将花尾胡椒鲷 (Plectorhynchuscinctus)受精卵置于不同盐度的水体中进行孵化。结果表明 ,当盐度≤ 2 6 .47时 ,花尾胡椒鲷受精卵沉于水底 ;当盐度≥30 .1 2时 ,花尾胡椒鲷受精卵浮于水面。以孵化率和畸形率为指标 ,花尾胡椒鲷胚胎发育的适宜盐度范围为 1 1 .2 0～ 45 .1 7,最适盐度范围为 2 6 .47～ 37.95。初孵仔鱼在盐度≤ 2 0 .99的水中沉入水底 ,盐度≥ 2 6 .47则上浮。本文还报道了将 1 3日龄的仔鱼置于不同盐度的水中进行培育的结果。
Plectorhynchus cinctus fertilized eggs were placed in different salinities of water hatching. The results showed that when the salinity was less than 26.77, the fertilized eggs of the cauliflower were immersed in the water, while the fertilized eggs of the caulis Based on the hatchability and malformation rate, the suitable salinity range for embryo development of the peppermouth beetle ranged from 11.2 to 45.7, and the optimum salinity ranged from 26.47 to 37.95. The newly hatched larvae sink to the bottom of the water in salinity ≤ 20.99, with a salinity of ≥ 26.77. This article also reports the results of incubating 13-day-old larvae in salinized water.
