After the gas exchange in the gills, the oxygenated blood passes on to the capillary network throughout the body of the fish. It is called “adipose”, which means “fatty”, because it has no fin rays It may serve to help with stability and to sense the flow of water over the fish’s back. Trout anatomy slideshow courtesy of the nyc and watersheds tic program background This pdf lays out the basics of trout anatomy with detailed photos and diagrams. Using dep’s lesson on the adaptations of trout around the world, talk about the evolutionary adaptations related to fish anatomy and review external trout anatomy.
The skeletal system provides support and flexibility, the digestive system breaks down food and absorbs nutrients, and the respiratory system allows the trout to extract oxygen from the water.
