适应南方多品种对虾育苗的育苗场

A hatchery suitable to multispecies of shrimps in South China

本文针对我国南方多季、多品种对虾养殖现状及这些种类不同的习性及生态特点,介绍一种适应南方多品种、多茬次、专业化对虾幼体培育的育苗场设计方案。内容包括:1.改造育苗池结构,使育苗池趋向小型化(每口育苗池面积24～40m^2),育苗池周边留工作道,使成为真正的半埋式,以便于操作。2.结合几个主要经济种类的暖、温性特点,配套增温、保温和调节光线强度设施,使能根据各种类的不同需要随时灵活调节,以满足各种类、各阶段对虾幼体的生态要求。实践证明,这样的设计是可行的。

The design of hatchery,which is based on the characteristics of cultivation of multi-species of shrimps and multibatch,and the different habits and ecological characters of thesespecies,is introduced in this paper.In the design,the hatcheky ponds are small,about 24 to40m^2 in area.The water temperature and light can,freely,be regulated in the light ofrquirements of each species.This design is suited to larval rearing on several occasions oneyear on the warm and temperate species too.Moreover,the workinglanes are reservedhatching ponds so that it is comfortable to work in the hatchery.It is demonstrated that thisdesign is right in larvel rearing of multi-species of shrimps.The design can be populated inthe southern China.
