摘要
近年来 ,养殖对虾业在全世界得到了迅速的发展 ,究其原因很多 ,但对虾饵料的解决是其中一个非常重要的因素。从天然饵料发展到配合饵料的过程中 ,对虾养殖业进入了指数增长阶段。然而随之而来的虾病 ,又使对虾养殖业进入了相对的滑坡阶段。为了解决这个问题 ,大量的科研工作者从饵料入手 ,研究对虾的抗病机理 ,有的学者提出了人工鲜活饵料 (如沙蚕、蛤、蝇蛆等 )能提高对虾的抗病能力 ,延缓病程。但是投喂鲜活饵料成本很高 ,而且营养成分不全。为此 ,有的学者提出了配合饵料和鲜活饵料配合使用。本文查阅了大量文献 ,试图对国内外对虾饵料的发展状况及其天然饵料、鲜活饵料和配合饵料的特点作一简要概述。
In recent year,aquaculture of prawns has been developed very quickly around the world.There are many reasons for that.But,the solution of prawns' bait is a very important factor.During the process from natural bait to assorted bait,aquaculture of prawns got into an exponential rise phase.At the same time,prawns' disease followed,which made aquaculture of prawns get into a relative decline phase.In order to solve the problem,many scientific research staff entered on the research of prawns' immunity from the disease by way of studying the bait.Some scholar believed that artificial fresh bait such as clamworms,clams,larvae etc can develop prawns' antidisease capacity and prolong the course of disease.But the cost of these fresh baits was very high and lack of plenty nutrients.Therefore,some scholars suggested that fresh bait and assorted bait should be arranged in pairs.This paper tried to give a brief review of the developmental history of prawns' bait at home and abroad and a simple description of the caracteristic of natural bait,fresh bait and assorted bait based on a large number of references.
