Very elucidating on the topic of koi fish raising from koi care, lifecycle and even disease care. I didn’t expect such an expansive view on this subject matter, and expected mostly rumination on pond preparation and care. I’m tempted to say treatment of this topic was sparse and perhaps lacking, but it in fact feels concise and to the point, deeper explaining of the “why” to the user. Due to this, users might find this book prescriptive and even a bit too strict. I’d offer that the strict tolerances that the book preaches are more situated for raising competitive koi as opposed to those of us for whom a Petsmart Koi will more than suffice.
Don’t expect hand holding on topics that were covered in a high school chemistry class. The nitrate cycle was explained in a single page and paragraph, all packed with details that could themselves reserve a chapter in it’s own book. I’ll need to do followup learning on how to properly measure for chemical imbalances and proper plants and devices to attack this problem area. The book simply offers a few solutions, but moves on to the many other areas involved in pond maintenance like oxygenation, koi numbers, measurement devices, temperature, ph levels, etc.
The section on all the koi varients was perhaps the most well done part of the book and provides a great jumping off point for koi that a person might practically acquire in their pond. It’s easily the best chapter of the book and perhaps placed in proper order for this book. It’s clear that the authors prioritize owners resourcing the bulk of their expenses on preparing the environment for which the koi will live and hopefully thrive. By the time i reached this section, i was much more willing to settle on less variant versions of koi as a practical hedge to investing in koi that, while not harder to raise, would be a much harder hit to the pocket.
Great book overall. Love that this sets a gold standard and saved me hours of watching koi videos and reading blogs. Certainly much more reading will be needed to properly complete a koi project end to end, but this guide was a great intro.
