Studies on the Seed Production of Urechis unicinctusⅠ. Influence of Water Temperature on Embryonic Developmentand Larval Rearing
单环刺螠(Urechis unicinctus)的人工苗种生产研究Ⅰ.水温对胚胎发育及 幼体培育的影响
Three experiments in the larvalurearing of kuruma shrimp, P. japonicus with different dosages and different feeding mode of an organic quickening-suporting curative compound were made- The application of Q. S. to the larval rearing of P. japonicus was investigated.
以复方有机疗效助长剂（简称Q．S．）的不同剂量和不同投喂方式对日本对虾（Penaeusjaponicus）各期 幼体培育进行三批的试验，分析了Q．S．在日本对虾 幼体培育中的应用效果。
A "safe level "calculated for larval of farmed P. penicillatus is 1. 38 mg/dm3 NO-2 -N. A more conservative "safe level,' is 0. 16 mg/dm3 NO-2 -N.
/cm2. In the ～pond 12-10, the density of nematodes is 0.27.0 inds. /cm2and the average density is 3.2 inds. /cm2.In the middle of culture phase, the nematode densities of both ponds reach a peak.
号池的线虫的密度为～个12-10 0.27.0 /cm2平均密度为个, 3.2 /cm2,到 幼体培育的中期,两个池的线虫密度都达到最高峰。
The experiment also showed that survival of larvae would not be affected even though the concentration of ammonia in rearing tanks reached as high as 1056. 4 μg/l.
the method for rearing larvae of Changjiang crab is as same as that for rearing larvae of the Yellow River crab,and there is no marked difference between the rearing rate,but the depth of overwintering water should keep at above 1.5 m,and the parent crabs’intensive culture should move up 15～20 days.
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.
