Biology
adjective: phototrophic
(of an organism) obtaining energy from sunlight to synthesize organic compounds for nutrition.
Stripers are phototrophic. They sense less daylight which translates to less time to synthesize food to get energy. So as the amount of daylight decreases they head South for longer days and more time to obtain energy.
