I'm pumped to learn more about fish because I love earth sciences but I also just want to commend you for doing this whole thing in the first place. Accessibility to academia and higher-level learning is so incredibly limited - by the cost of schooling, paywalls on academic literature, even just by overly jargon-intensive vocabulary - so it's always really nice to see something like this be free and open to everyone.

This bring me back to my college life...This is some great content and I can not believe it is free...When I was learning Ichthyology, beside all science, I remember that my prof use to also teach us which fish is best for smoke and which fish is best for fry...not a joke...that is what is like to learn animal related topic in some part of Alberta Canada...somewhat they will all came to hunting, fishing and ranching... 'Sander vitreus, taste really good but you can not fish it anymore because we almost eat them all. Ameiurus nebulosus, can not fish them either, they are pretty good though, use to be sell as fake lobster. Catostomus commersonii, bottom feeder, taste like dart, no body want it, you can try, there is no fishing restriction on them, but I bet you won't like it.etc....". This youtube video is a better class than the "professional education" I got.

Thank you for creating this AVNJ. I'm 22 and I started following your channel a few weeks ago and I'm really enjoying it. I grew up in the coastal regions of Southeast Asia and near to the massive lake Malawi. I was always interested in Marine Biology and have an Advanced Open water diving license, but I haven't had the time to study the field properly. I was nearly going to help some researchers map some reefs in Cambodia this winter but Covid cancelled the operation. I'm studying in the Netherlands right now doing Political Science and International Relations with a minor in sustainability because I want to help solve the worlds problems; but creating music and understanding the Biosphere, and especially the beauty of Marine life, are more deeply rooted passions that I'll forever be drawn to. I appreciate your work. I hope you touch on the Clown Triggerfish somehow.
