一、前言 人工饲养鱼事业的不断发展,必然要求饲料工业部门能提供大量的品质优良、种类齐全的鱼饲料。为了达到理想的饲养效果,鱼饲料必须具有一定的耐水性能,在一定的时间内悬浮于水中,为鱼的捕食创造条件。但是.饲料被鱼吮入后,又希望它具有易溶和易消化的性能,使其营养能够被迅速吸收。因此鱼饲料的耐水性能需适度。过低.引起饲料浪费;过高,又不易被鱼消化吸收。解决这矛盾的较简易的方法是,在鱼饲料成形后
I. Introduction The continuous development of the artificial rearing fish industry necessarily requires that the feed industry department provide a large quantity of fish feed of good quality and variety. In order to achieve the ideal feeding effect, fish feed must have certain water resistance, suspended in water for a certain period of time, to create conditions for fish prey. However, after the feed has been sucked into the fish, it is also desirable that it has the properties of being soluble and digestible so that its nutrition can be quickly absorbed. Therefore, the water resistance of fish feed needs to be moderate. Too low, causing feed waste; too high, but not easy to digest and absorb fish. A simpler way to solve this paradox is after fish feed is formed
