摘　　要：为了提高膨腹海马(Hippocampus abdominalis)养殖效率,了解温度、配对方式与数量、养殖密度等对膨腹海马生长、存活及生殖的影响,本研究测定了不同温度、不同雌雄数量比对膨腹海马亲本产苗量的影响和不同培育密度对膨腹海马苗种生长、存活的影响。研究结果表明:膨腹海马亲鱼适宜的繁殖水温范围为16.0~19.0℃;膨腹海马雌雄鱼比例控制在1∶1、2∶3的范围内繁殖效果最佳,产苗量相对较高;膨腹海马苗种生产的早期阶段(30日龄前),最适培育密度为0.50~1.00尾/L,中期阶段(30~60日龄),最适培育密度为0.25~0.50尾/L。本研究为膨腹海马人工繁殖与育苗技术提供了科学数据。In order to improve the breeding efficiency of seahorse,Hippocampus abdominalis,and understand the effects of temperature,pairing mode,stocking density and breeding density on the growth,survival and reproduction,we studied the effects of different temperatures and different sex ratios on the seedling yield,and the effects of different breeding densities on the growth and survival of the seedlings.The results showed that the suitable breeding water temperature for broodstock was 16-19℃.The best ratio of male to female fish ranged from 1∶1 to 2∶3,resulting in relatively high seedling yield.In the early stage(within 30 days)the optimal density was 0.5-1.0 ind./L,whereas in the middle stage(between 30 and 60 days)it was 0.25-0.50 ind./L.Our study can be taken as scientific reference for artificial propagation and seedling in H.abdominalis rearing.
