Fish are very important to a majority of ecosystems in this world and their sex lives need to be pristine so that they are able to keep contributing to their ecosystem and this world. Please watch my Snapchat Story below as I go through the physiology of fish reproductive systems, the endocrine system and how synthetic hormones affect the reproductive success of fish populations.
