摘要: When searching for food different fish species use the same sensory mechanisms differentially. At one extreme there are omnivorous fishes such as catfish and carp that, in addition to vision, taste system excite release reflex responses olfactory discriminate chemical stimuli. On other predatory that detect prey visually and, if not conditioned differentially at fry fingerling stages, do chemosensory information finding all. Depending on they collect food, have been studied date occupy following ecological niches. (1) Bullhead (Ameiurus melas) type niche: bullhead catfishes tactile senses appetitive consummatory phases of feeding behavior. They also by passive electric sense. (2) Channel (tctalurus punctatus) channel vision predation addition, senses. (3) Carp (Cyprinus carpio) goldfish (Carrasius auratus) visual collection, taste-controlled snapping/biting oral sorting separate edible from inedible objects. (4) Rainbow trout (Oncorhyncus mykiss) hunters farmraised rainbow and/or olfaction get excited search food. (5) Exclusively nature, European hue hen (Hucho hucho) walleye (Stizostedion vitreum) consume exclusively living crustaceans locate vision.
