Chasing Giants: In Search of the World's Largest Freshwater Fish
Join Zeb Hogan, host of the National Geographic television show Monster Fish , on the science adventure of a lifetime.
On May 1, 2005, a Thai fisherman caught a truly monstrous Mekong giant catfish. At 646 pounds, it captured the world’s attention, and with awe and wonder, it was deemed the largest freshwater fish on record. There was no denying its size, but when biologist and research associate professor Hogan saw a photo of the fish, he wondered if it really was the biggest in the world. To his surprise, no one had systematically sought to answer the Which of the giant freshwater species really was the largest?
Seeking to answer that question has brought Hogan face to face with massive arapaima and piranha in the Amazon, alligator gar in Texas, pigeon-eating wels catfish in France, stingrays in Cambodia, and the gnarled-toothed sawfish in Australia. Part of his scientific adventure has been captured on Monster Fish , and Hogan now tells the full story of his 25-year quest to understand the mysteries of some of the oldest, largest, most bizarre creatures on Earth.
The fate of these giant fish motivates Hogan to understand the various species he studies. The megafish’s numbers are dwindling, and the majority of them face extinction. In this book, he teams up with award-winning journalist Stefan Lovgren to tell, for the first time, the remarkable and troubling story of the world’s largest freshwater fish. It is a story that stretches across the globe, chronicling a race against the clock to find and protect these ancient leviathans before they disappear forever.
Chasing In Search of the World’s Largest Freshwater Fish combines science, adventure, and wonder to provide insights into the key role the massive fish of our lakes and rivers play in our past, present, and future.

Non-fiction that seeks to answer the question: What is the world’s largest freshwater fish? Author Zeb Hogan is a research biologist at the University of Nevada, Reno, and host of National Geographic’s show Monster Fish. Hogan has traveled the world for twenty years searching for and studying rare, large freshwater fish species. This book documents his travels to places such as Thailand, Cambodia, Vietnam, China, Brazil, Guyana, Australia, Russia, and more. In addition to the search for the largest freshwater fish, he informs the reader of the role these species play in the ecosystem. He relates the environmental consequences of human actions such as overfishing, dam building, and pollution.
One of the aspects of this book I most enjoyed was the way Hogan engages the local inhabitants of the regions he visits. Many of the people who guide him are those who fish as a way of life. Readers learn about the culture and history of these regions in addition to specifics on the types of fish that live in their waterways. Examples of “Monster Fish” include paddlefish, sawfish, sturgeon, catfish, and rays. I was astounded that fish weighing hundreds of pounds live in these rivers! I learned a lot from this book. Recommended to those who enjoy learning more about and preserving our natural world.
Many thanks to NetGalley and the publisher for providing an advance reader’s copy.

I really enjoyed this book. It wasn’t quite what I expected, but I liked the different threads that Hogan includes, such as his own research work, trying to find the world’s largest fresh water fish, conservation efforts, history, and ichthyology. My favorite parts were the descriptions of rivers and dams, something I knew nothing about before this book, and the history of various fishes, especially the ancient and weird fish. The voice of the narrative is very lively, and I found the whole book engaging, whether I was reading about Hogan’s adventures in Cambodia and Mongolia (my favorite destination Hogan describes) or about Hogan’s childhood. Overall, I really enjoyed this book and would recommend it to people who like fish, weird things, conservation, and rivers. I read parts of this to my dad but most of it alone. My dad never really seemed to get into this one. Some things, he’d comment, “Wow,” but for the most part, I don’t think this was his thing. It happens 🤷🏻♀️

If you got this hoping for pictures of giant fish, you will be disappointed. However, if you got this for the stories of learning more about giant freshwater fish, you will be thrilled! Zeb Hogan gives you the insider’s look at how he pursued the research and expanding the knowledge base of these monstrous sized fish. It is well founded and explained well (you don’t need to be brilliant or even science minded to understand it and appreciate it). It is informative and enjoyable as you travel through various regions in the world.

Spanning roughly 25 years of searching for the largest freshwater fish, Prof. Hogan’s stories of research, conservation and adventures are engaging. Freshwater fishes are often overlooked because they are not as exciting as their saltwater cousins. However, the story of freshwater fishes growing to giant proportions in environments not so far from home is engaging and keeps you turning pages.
As a fisheries and wildlife major myself, but one that doesn’t really fish, I found the story of Prof. Hogan’s journey through his PhD work into his career beyond really interesting and relatable. It also brought back great memories of my field tech years doing fisheries work. Too bad I was chasing minnows and not giants. Recommend for anyone interested in conservation, fisheries and river ecology. 4 stars.

As the author rightly points out, freshwater fish are somehow neglected animals. There are so many popular science books about birds, large predators, even insects - but I think this is the first I have read about the creatures that live in our lakes and rivers.
Zeb Hogan's quest to find the largest freshwater species is just a pretext for a compelling story of fish biology, evolution and ecology. The book combines scientific memoir, travelogue, popular science and behind-the-scenes details of how National Geographic TV shows are made. It is well written, full of adventure and curious details - my only complaint is that it can be a little chaotic as the author jumps between different topics in subsequent chapters.
I think it will be a pleasant read for anyone interested in biology and the realities of fieldwork in exotic parts of the world.

My thanks to both NetGalley and the publisher University of Nevada Press for an advance copy of this book on the freshwater life that is found all over the planet, and how little we still don't know about them.
About 71 percent of the planet is covered in water, and yet in many ways all that water is still a mystery, a final frontier in a way. The seas and oceans teem with life, as does every waterway stream, lake and rivers. What lives there is still being discovered even now. Though our conservancy leaves much to be desired. The news is filled with stories about poisoned waters making it hard to towns and cities to even get clean drinking water. What this is doing to the creatures that live in these waters is anyone's guess. Many mysteries will probably be unsolved or in many cases undiscovered, as is pointed out in the following book there wasn't even a consensus on what the largest freshwater fish is. Which makes the work of educators and media personalities so important in pointing out the mysteries not only of the deep sea, but what lives near our homes, and what many people gather to provide food for their families. Zeb Hogan, host of the National Geographic television show Monster Fish and writer journalist Stefan Lovgren have written Chasing Giants: In Search of the World's Largest Freshwater Fish, a book about their travels discovering fish, and what lessons they have learned and shared along the way.
The book begins with a Thai fisherman hoping for a good catch that will provide for his family. The fisherman offers a tribute to the spirits for a catfish, a large one, but one that has become rare in his area. Something much have worked for soon the fisherman and his companions were pulling a huge catfish to shore. One that weighed almost 650 pounds, and was over nine feet long. This was thought to be one of the largest freshwater fish, but as Zeb Hogan knew, no one could really be sure. No one was really keeping track, or knew for sure what different varieties of fish could grow to, or if there could be larger. Many fishermen who fish for their families survival might be far out of contact with authorities to share information. Hogan had set up hot lines and dealt with fisherman on rare fishes before, and thought that this would be a good project to get behind. Soon Hogan and his team were traveling the world finding sting rays, fish in the Amazon and even France, learning about the culture of the people fishing, and the fish themselves. And how the world of the fishes were changing, sometimes not for the best.
The book is a bit of memoir, along with fish stories and conservation efforts dealing with fish and other animals. The writing is very good, very informative and interesting with a lot of fish stories, and again even more in trying to get information. Stories about driving through monsoon rains to get to where certain fish have been caught. Followed by stories of trying to release these large fish into the waters, tagged as part of tracking experiments. The biology is well explained and tells a lot about the fish, the people who count on the fish for life, and what is happening to them as the world changes. The details are informative and would be interest for young readers who like to read about the natural world.
Recommended for readers of both fishing stories and conservation efforts. Also for people who might like to get into marine biology, just to learn about the different aspects of study, and how one little question can lead a person around the world for the answers.

Chasing Giants: In Search of the World's Largest Freshwater Fish
is a captivating book that takes you on a journey with Zeb Hogan, a biologist and host of the National Geographic television show Monster Fish. The book, told from Hogan's perspective, is co-written by Stefan Lovgren a journalist and filmmaker. Together, they explore the fascinating and endangered world of "megafish" - the giant freshwater species that can grow to enormous sizes.
The book is based on Hogan's 20 year quest to find out which megafish is the largest in the world, a question that was sparked by a photo of a 646-pound Mekong giant catfish caught by a Thai fisherman in 2005.
Hogan's quest proves to not only provide a thrilling adventure story, but also a sobering reminder of the threats that these megafish face. Fresh water fish, and megafish especially, suffer from overfishing, habitat loss, pollution, and climate change. Hogan and Lovgren make a compelling case for why we should care about these ancient leviathans of our lakes and rivers, and what we can do to protect them before they disappear forever.
Along the way, Hogan and Lovgren encounter amazing creatures such as arapaima and piranha in the Amazon, alligator gar in Texas, wels catfish in France, stingrays in Cambodia, and sawfish in Australia. They also learn about, and explain to us, the environmental threats and conservation challenges facing these ancient leviathans, and the complex cultures and places that depend on them.
Hogan's passion, curiosity, and empathy shine through as he relays his experiences as a scientist and adventurer. He gives us insights into the biology, ecology, and behavior of the megafish, as well as the history, myths, and legends surrounding them. The book is full of fascinating stories and anecdotes that will appeal to readers of all backgrounds and interests.
I enjoyed Chasing Giants . I learned about a hidden and mysterious world that I had known very little about before cracking open this book. I was impressed by the authors' dedication and courage to pursue their quest, and by their efforts to raise awareness and protect these magnificent creatures. The book is well-written, informative, and engaging, with vivid descriptions and anecdotes that bring the fish and their environments to life.
I would recommend it to anyone who is interested in fish, wildlife, nature, adventure, or science.

National Geographic fans may be familiar with Zeb Hogan and his show Monster Fish. I didn’t know anything about him or the show but was intrigued by his quest to find the largest freshwater fish. His show is available on Apple TV for a fee, but I did find several videos on Youtube as well as a TED Talk he did at the University of Nevada. Be sure to check them out if interested.
Hogan travels to Thailand and Cambodia in search of the Mekong Giant Catfish, hoping to catch and see one for himself. These fish are truly monstrous coming in at over 6 feet and over 200 pounds. I can’t even imagine catching a fish this size let alone seeing one in person. These fish are having trouble surviving due to excessive fishing, environmental changes, and developments happening near their natural habitat. By training the local fisherman and tagging the fish, Hogan and his team have been able to keep track of and save the declining population of many of the endangered fish in the rivers there.
“The decline of giant fish was one hundred percent the result of human activity. And if humans were the ones causing this catastrophe, then humans could also stop it.”
If you like the “thrill of the catch” kind of stories, keep in mind this has a slower pace and lots of research and stories attached. But, there are some great stories of some amazing fish and surprising catches. He does find the largest freshwater fish, but you’ll have to read it yourself to find out what it was and where it was located.
“Handling a large fish is always a thrill. Immediately, I am filled with adrenaline, trying to figure things out. How does the fish feel? How does it move? How does it react to being caught? Or being handled? Is it injured? How can I ensure that the fish is released back into the wild unharmed? It’s my favorite part of the job, being in the field, handling the fish as rare and special as the sawfish.”
There were a few photos in the book, but I wish there were more. I was doing a lot of googling to see where in the world he was catching these fish and what certain fish looked like even though his descriptions were pretty accurate. His youtube videos were also pretty accurate in how he described the fishing, netting, and catching/releasing the fish in the book. I learned so much about fish I have never even heard of or knew very little about including sawfish, lungfish, alligator gar (that I was surprised can be found in Iowa rivers), and arapaima to name a few.
For those that like adventure types of books, National Geographic shows, or fishing, I recommend this book. Even though most of this book talks about places around the world, there are some pages that discuss large fish in the US.

Hogan writes about his travels around the world in search of the largest freshwater fish. He filmed a series entitled "Monster Fish", from 2009 to 2015, which included over twenty episodes, each one focusing on a different location and different fish.
Most of the book is a description of the author's travels. The amount of information on the natural history of the various fish is surprisingly minimal, being largely about their preferred habitat and the methods used by the locals to catch them.
The fish include arapaima, gars, sawfish, catfish, stingrays, sturgeon and others. One out of every twenty vertebrate species on the planet is a catfish.
UNESCO designated the Tonle Sap Lake an official biosphere reserve in 1997. The basin’s square mileage is equal to the forty-eight contiguous US states. Some studies suggest that more fish are drawn from this one lake than from all of North America’s rivers and lakes combined.
A major area of Hogan's studies have been about the effect of dams on freshwater fish. Most species move along the rivers to spawning grounds. Dams have severely curtailed this movement, and resulted in huge reductions in the the numbers of migratory fish.
The Fraser River in British Columbia has a healthy population of white sturgeon as there are no dams on he river.
An extraordinary fact about the arapaima is that it breathes air and may survive up to 24 hours outside of water. It can stay submerged for ten to twenty minutes at a time, but then it needs to come to the surface to breathe. When it rises, it makes a distinctive coughing noise. With its small gills, it sucks in oxygen using a modified swim bladder that opens into the fish’s mouth and acts as a lung.
A small proportion of females of the smalltooth sawfish, a species that maintains a relatively healthy population in Florida waters, reproduce on their own, without any male input, through parthenogenesis.
The wels catfish is truly a real-life monster. Also known as the European catfish, or sheatfish, it is the largest-bodied freshwater fish of Europe, potentially growing more than sixteen feet long and possibly attaining a weight of more than 300 kilos. Medium sized wels prey on pigeons.
In the late 1800's, over five million pounds of lake sturgeon were reportedly taken from Lake Erie in a single year. While dams and over-fishing have hugely reduced the number of lake sturgeon, Wisconsin has managed to sustain a large population. The Lake Winnebago system now has the largest self-sustaining stocks of lake sturgeon in North America.

We all know the biggest land mammal and the largest sea creature but, what is the largest freshwater fish? No one knows for sure and Zeb Hogan has devoted his life to trying to find out. This volume is a mixture of memoir, travelogue and science book. Hogan tells readers a little about his background, but mostly all of his adventures studying fish all over the world. It is heartbreaking to learn how much these creatures have suffered as a consequence of industrialization. I never thought how dams have affected their lives, leading to the extinction of so many species that we’re not even aware of. To be honest, I read every book I can about animals but I’d only come across a few about fish, and most are about the ones who live in the sea. Hogan finds many cool species, from electric eels, rays, catfish and many other creatures that I’d never even heard of. The science bits were a little too technical, but it was mostly all the content devoted to fishing techniques that went over my head. I’m more into ethology so this book didn’t engross me as much as I expected, but if you’re looking to learn about the denizens of lakes and rivers, this is a great way to start.

Review of eBook
Imagine a giant catfish caught in the Mekong River . . . almost nine feet from head to tail, weighing six hundred forty-six pounds. Is this the largest freshwater fish ever caught? Why did some fish grow so big?
And so begins The Megafishes Project.
Travel with the author as he searches for the leviathans of the river and seeks answers to their decreasing numbers. Can the giant fish be saved?
This fascinating look at leviathan freshwater fish is both informative and intriguing . . . travel with him to the Amazon in search of arapaima and piranha; search for alligator gar in Texas. Head to France to find wels catfish, to Cambodia in search of stingrays, and seek gnarled-toothed sawfish in Australia.
The only disappointment amid all these fascinating facts is the lack of pictures. Wouldn’t it be amazing to see a picture of these leviathans?

Initially interesting there are only so many ways to tell the story of scientific study after scientific study identifying large freshwater fish species. Over 20 years the author travels to every continent except Antarctica conducting studies to determine the life span, migratory range, size and estimated population of the largest freshwater fish. What was abundantly clear is that the building if hydroelectric dams, mining, and other human behaviors have caused some of these species to become extinct, some extinct in dammed rivers, and all threatened. Most of the giant fish are not fished commercially as they are rare and only found in extremely remote locations. They are caught as by-catch on occasion.
The winner is the freshwater ray found in the Mekong River. I did have fun looking each fish up on the web for photos and videos. Most are so ugly but HUGE - taking 4-14 men to lift them safely from the water for weighing & tagging.

I read about 25% of this ARC before it disappeared from my device and I was unable to download it again. I will write a review based on the 25% I was able to read.
This book is intelligently written and interesting. I have not watched the author's TV program or heard of him before. The topic intrigued me. I have a strong science background which is not necessarily required to enjoy this book. It seems to have been written for an educated reader or at least for someone with some general knowledge of science. The ARC I received does not contain photos, at least not in the section I accessed. It also does not include references, a bibliography, or appendices other than an index, which was inserted as a place holder in the ARC. In my opinion, photos would broaden the appeal of this book.
Thanks to the publisher and NetGalley for an ARC in exchange for an unbiased review.

Fisheries research biologist Dr. Zeb Hogan and science journalist Stefan Lovgren share fascinating stories about efforts to study and save the world’s largest freshwater fish. Dr. Hogan has spent the last 25 years trying to determine the largest freshwater fish species, a question that has been surprisingly difficult to answer. He has traveled all over the world studying fish populations, the threats to their health, and efforts to save them.
Part memoir and part scientific adventure, this is a well-written, exciting story for anyone interested in fish biology, field research, and conservation efforts. I discovered interesting new facts on almost every page. I was particularly happy to learn about how researchers are working with local villagers and fishermen to study and preserve these species.
I was provided an unproofed ARC through NetGalley that I volunteered to review.

This begins with the author wondering what the world's largest freshwater fish is......& then the book follows his quest to search out that answer. He actually makes a great career out of it, does a lot of traveling & has lots of adventures. He really put together a very readable book, even to a person who isn't into fishing! I learned a lot about freshwater fish....all over the world....paddlefish, rays, gar, sturgeon, eels, catfish & others, about different countries & their landscapes, conservation, about habitat loss, overfishing, the effect of dams & pollution, & sadly....extinction. It's quite an interesting look into that career/vocation/science. I learned a lot, & could recommend it to anyone!
I received an e-ARC from publisher University of Nevada Press via NetGalley, & offer this ....my own fair & honest review.

I used to love the show River monsters with Zeb Hogan and couldn’t wait to read this book chasing Giants written by Zeb Hogan and Stefen Lovgren End it did not disappoint from his studies in Thailand as a young college student to his day is on the show with his good body Brant Allen it’s all here and his search to find the biggest freshwater catfish, something that continues to this day. He even talks about his days in Cambodia his heart for stingrays and much more I truly enjoyed this book and hardly recommend it if you’re a fan of adventure in those living life the Rhône original way then you’ll definitely love this book I certainly did and highly recommend it. I want to thank the publisher and Net Galley for my free arc copy please forgive any mistakes as I am blind and dictate my review.

This is a captivating blend of adventure memoir, ecological science, and urgent conservation plea. Written by Zeb Hogan, the renowned biologist and host of National Geographic's Monster Fish series, and award-winning journalist Stefan Lovgren, the book chronicles Hogan's extraordinary twenty-five-year quest to locate, study, and protect the planet's most massive freshwater fish.
The narrative takes readers on a global journey from the Mekong River in Cambodia to the Amazon Basin, from the rivers of Australia to remote waterways beyond. Hogan's quest is driven by a profound curiosity about these "megafish"—ancient leviathans like giant stingrays, catfish the size of humans, and six-foot-long pikeminnows, some weighing over 200 pounds. More than a simple catalog of giants, the book delves into the deep connections between these fish and human cultures, exploring their roles in local traditions, economies, and ecosystems.

It took me a while to get into the book but I wound up enjoying it. It was interesting to learn that there are so many species of giant freshwater fish but at the same time it’s disheartening to read that so many are in danger of disappearing. But hopefully the research that the author and other scientists are undertaking to understand and save populations of these giants will help.
I read this on a kindle and the one thing that I wish had been set up differently was having all of the pictures in the center of the book. While it’s easy to flip back and forth in a print copy, I wasn’t able to see the fish the author was talking about until I reached that section and going back to take another look was difficult.

I was not the target audience and I had really hoped for pictures.
Nonfiction.
Who is the author? A research biologist at the University of Nevada, adventurer, conservationist, diver, photographer, videographer, educator, researcher.
What many of these enormous pisces face is extinction by greedy humans.
Where? Anywhere in this world where legends and rumor lead.
How? By travelling with a competent journalist to discover just what is happening in the world of fish.
Research includes local cultural anecdotes and scientific data.
I requested and received an EARC from University of Nevada Press via NetGalley. Thank you!

#NetGalley asked, "Do you want to read a book about the search for giant freshwater fishes?" I replied, "Heck, yeah!" This was not the most readable science book I've ever read and we seem to jump back and forth and to and fro amongst the author's many fishery projects so it's hard to keep them all straight. That said, the enthusiasm and passion the author has for this subject is clear and conveys itself on the page. I've never seen the National Geographic series that this author did on the same topic of monster-sized freshwater fish, but the book was fascinating. We get to travel the world with the author learning about river eco-systems and conservation all while hunting for the largest freshwater fish we can find. I thoroughly enjoyed reading this book!

Chasing Giants
Yes, there are still monsters on earth! Giant size freshwater fish that is. Biologist Zeb Hogan has spent 25 years traveling the world studying these rare and unusual fish. Many of these creatures are in danger of extinction. The authors’ point out that once these creatures die out they are gone forever, and so is whatever knowledge might have been gained from them.
This is a fascinating look at some little known animals. There is a tie-in with a television program. Both teens and adults with an interest in nature would enjoy this book.

Have you watched the Nat Geo show "Monster Fish"? If you have, you know Zeb Hogan as the host. I have watched his show and loved the way he tells a story, so when I learned that he had written a book, I HAD to read it! This is the story of his search for the largest freshwater fish on the planet. Zeb has a way with words, and this book is like walking through this story with him sitting across the table from his as he shares one of the best fish stories ever!

This is one of those books that while you are reading, you keep showing the pictures nad articles to everyone in the room. Then you tell someone else about one of the stories, so you pull the book out to show them. This is repeated so often, you don't put the book away, you keep it handy so you can show and tell. Just be careful that no one "borrows" it. A great book full of information and amazing stories.

Had to read for class but ended up thoroughly enjoying it. Have a great appreciation for freshwater ecosystems now and an even greater hatred for dams.

This review is based on an ARC of Chasing Giants: In Search of the World's Largest Freshwater Fish which I received courtesy of NetGalley and the publisher (University of Nevada Press).
2.5 stars
Chasing Giants is a treasure trove of fish factoids that satisfies the itch of the armchair traveler craving something exotic and aquatic. Although a great read for amateur ichthyologists, this book is not for everyone. If you yearn to learn about big fish around the world and how local communities react to their presence you will be well met. However, if you just like to see big creepy fish, I'd recommend you just watch River Monsters reruns.
Interesting and educational, albeit somewhat bland, Chasing Giants is a middling nonfic selection.

3.5 stars and recommended recommended for anyone interested in ecology and environmental issues, anglers and those who love fish, or those who are interested in what science research can look like around the world.
The book loosely follows Hogan’s quest to figure out what species is the largest freshwater fish in the world. I found the chronology a bit hard to follow in parts as the authors jump from place to place and topic to topic, but the book was full of fascinating stories that will appeal to readers no matter what their background in science.
Great insights into environmental issues facing freshwater ecosystems around the world and the amazing world of giant fish. I enjoyed traveling vicariously through the authors to Southeast Asia, the Amazon, Arizona, Mongolia, and more.
While Zeb Hogan and Stefan Lövgren are co-authors, the book is written from Hogan’s perspective. While sometimes I found him a bit of a scattered storyteller, Hogan’s curiosity, empathy, experiences, and drive to protect the environment make him an able narrator.
