科学研究人员根据对鱼类胃含物的测定,将鱼类的食性分为以下四大类:①鱼食性鱼类,②肉食性鱼类,③杂食性鱼类,④浮游生物食性鱼类。 1.鱼食性鱼类:海洋中生活的主要鱼类有:鲨鱼、金枪鱼、鲣鱼、银带鱼、杜父鱼、鳗鱼、(鱼师)鱼、鳚鱼、毛烟管鱼、鲑鱼等。内陆淡水中生活的鱼类有:鳡鱼、蒙古鲌、翘嘴红鲌等。 2.肉食性鱼类:海洋中生活的主要鱼类有:东方鲀、鲈鱼、鲐鱼、大黄鱼、小黄鱼、多鳞(鱼喜)、刺(鱼叚)虎等。内陆淡水中生活的鱼类有:青鱼、鳜鱼、星鱼、鲶鱼、虹鳟鱼、红鳍鲌、黄鲦(鱼桑)鱼等。
Scientific researchers based on the determination of fish stomach content, the fish food into the following four categories: ① fish-eating fish, ② carnivorous fish, ③ omnivorous fish, ④ plankton feeding fish. 1. Fish-eating fish: The main fish living in the oceans are: sharks, tuna, anchovies, silver octopus, daddy fish, eels, (croaker) fish, anchovies, flue-cured tobacco, salmon and the like. Inland freshwater fish live in: mandarin fish, Mongolian pomfret, Cichorrets and so on. 2.
