本文对高体受精卵和早期仔色发育与盐度的关系进行了初步研究。结果表明：受精卵在不同盐度下表现出不同的沉浮性，在盐度为30％。以下的海水，呈沉性；在32‰以上的海水，呈浮性；受精卵孵化的适盐范围为30－40‰，最适为32－35‰；仔鱼在不同盐度海水中的分布状态是：盐度低于30‰时，主要分布于中下层，活力差；盐度高于32‰时，主要分布中上层，活力好；在不同盐度和无投饵状态下，仔鱼生存指数SAI大小为：盐度25－40‰，SAI为10．20－18．80，其中在32－35‰时，SAI值最大（18．30－18．80）。从不同盐度下仔鱼的分布状态及仔鱼的生存指数综合分析，高体仔鱼培育的最适盐度范围为32－35‰。
This article has carried on the preliminary research to the relation between the high body zygote and the early development of the baby and the salinity. The results showed that the fertilized eggs showed different uplifting at different salinities with a salinity of 30%. The following seawater was subsidence; in 32 ‰ above the sea water, was floating; fertilized eggs hatch suitable salt range 30-40 ‰, the most suitable for 32-35 ‰; larvae in different saltwater seawater distribution The salinity is below 30 ‰, which is mainly distributed in the middle and lower layers with poor activity. When the salinity is higher than 32 ‰, it is mainly distributed in the middle and upper strata with good vitality. Under different salinities and no-feeding conditions, the larval survival index (SAI) The salinities ranged from 25-40 ‰ and SAI ranged from 10.20-18.80, with the highest SAI (18.30-18.80) at 32-35 ‰. Based on the analysis of the distribution of larvae and the survival index of larvae at different salinities, the optimal salinity range of larvae was 32-35 ‰.
