为提高鱼类对饲料养分的利用效率,必须深入研究鱼类的营养需要并弄清鱼类摄食与养分消化吸收的关系。一般讲,缺乏鱼类摄食方面的知识,就不可能合理地经营养鱼业,而忽视鱼对饲料的嗜好性也将是饲料问题的一个重大缺陷。鱼类摄食行动及其对饲料(包括饵料)的嗜好性是一个相当复杂的问题,它有着各种内、外因素的相互深刻的关联。因此,要探明鱼类的摄食机制并非易事。最近在国际上由于电生理学与化学生态学研究的进展,鱼类化学感觉和促摄物质的
In order to improve the utilization efficiency of fish to feed nutrients, we must deeply study the nutritional needs of fish and clarify the relationship between fish feeding and nutrient digestion and absorption. As a general rule, the lack of knowledge of fish consumption makes it impossible to operate the fish farming rationally. However, neglecting the preference of fish for feed will also be a major drawback to the feed problem. Fish feeding action and its preference for feed (including bait) is a rather complicated issue with a profound correlation between various internal and external factors. Therefore, to find out the feeding mechanism of fish is not easy. Recently, due to the progress of electrophysiology and chemical ecology in the world, the chemical sensation of fish and the
