随着鱼类及甲壳类水产动物养殖业的迅速发展,小面积高密度的养殖方式正在兴起.高密度养殖,虽可增加养殖数量,提高产量,但由于动物之间相互接触多.容易碰撞,往往会使动物发生外伤,进而造成细菌感染.导致成活率低.本剂可以预防、抑制和减免上述情况的发生,并能促进鱼类及甲壳类水生动物健壮生长.现将该剂的原料、配方、配制及使用方法介绍如下,供各地鱼民及水生动物养殖户参考和使用。1、原料与性质①色氨酸学名β-吲哚基丙氨酸。它有3种异构体。1体(左旋体)多片状晶体.无味,溶于水和热乙
With the rapid development of aquaculture of fish and crustacean aquaculture, small-area, high-density farming is emerging.High-density farming can increase the number of breeding and increase the yield, but due to the mutual contact between animals and more easily collided, The animals often cause trauma, and then cause bacterial infections, resulting in low survival rate.This agent can prevent, inhibit and reduce the occurrence of these conditions, and can promote the robust growth of fish and crustacean aquatic animals now the agent of raw materials, Formulation, preparation and use of methods described below, for all local fish farmers and aquatic animal farmers reference and use. 1, raw materials and nature ① tryptophan scientific name β-indole alanine. It has 3 isomers. 1 body (L-body) multi-plate crystal tasteless, soluble in water and heat B.
