Fish's Endocrine Systen
In fish and other marine animals, hormones play a similar role regulating various biological processes such as molting of the exoskeleton, growth, reproduction, and development. While the endocrine organs of fish may differ from those in humans (Figure 1), their hormones that are similar in structure, similarly synthesized and have many of the same mechanisms of action. Many of the same building blocks in the biosynthesis of these hormones are shared between species and conserved in human hormones, thus contributing to non target organism exposures and biological effects.
