摘  要:
以罗氏沼虾幼体为研究对象,研究了60、110、160、210尾/L共4种养殖密度和2种不同投饵策略组合而成的8种养殖模式对罗氏沼虾幼体生长发育的影响。结果表明,罗氏沼虾幼体适宜的养殖密度为110~160尾/L;在养殖密度和投饵总量不变的情况下,投饵6次/d比投饵3次/d培育出的幼体存活率更高、变态发育时间更短。

摘  要:
The larvae of Macrobrachium rosenbergii were taken as research objects,eight breeding patterns which consisted of4 breeding densities( 60,110,160 and 210 larva / L) and 2 bait-casting strategies were designed,and the influences of different breeding patterns on the growth and development of this shrimp were studied. The results showed that: the appropriate breeding density of Macrobrachium rosenbergii larvae was 110 ~ 160 larva / L; under the conditions of constant breeding density and total bait-casting quantity,the larvae fed 6 times / d had higher survival rate and shorter metamorphic development time than those fed 3times / d.
