Abstract

Rearing experiments were conducted using several regimes combined with different photoperiods and water temperatures to investigate the role of temperature and photoperiod as environmental cues regulating reproduction in red marbled rockfish, Sebastiscus tertius. The initial gonadosomatic index (GSI) was 1.62±0.32% and that in the 15°C control was 7.01±0.46% at the end of the experiment. The highest GSI was 9.10 ± 0.35% in the 12L:12D photoperiod-treated fish. The highest GSI at 19°C was 15.03±0.86% in the 12L:12D photoperiod treatment. The initial hepatosomatic index (HSI) was 3.09±0.72% and that in the 15°C control was 3.88 ± 0.45%. The highest HSI was 4.00 ± 0.56% in the 15L:9D treated fish. The highest HSI at 19°C was 4.05±0.63% in the 12L:12D treated fish.

摘要

采用几种不同光照周期和水温组合的养殖方式进行饲养实验，以研究温度和光照周期作为环境信号对红石斑鱼（Sebastiscus tertius）繁殖的调节作用。实验开始时性腺指数（GSI）为1.62±0.32%，实验结束时15°C对照组的性腺指数为7.01±0.46%。在12小时光照:12小时黑暗（12L:12D）光照周期处理的鱼中，最高性腺指数为9.10±0.35%。在19°C时，12L:12D光照周期处理下的最高性腺指数为15.03±0.86%。实验开始时肝脏指数（HSI）为3.09±0.72%，15°C对照组的肝脏指数为3.88±0.45%。在15小时光照:9小时黑暗（15L:9D）处理的鱼中，最高肝脏指数为4.00±0.56%。在19°C时，12L:12D处理的鱼中最高肝脏指数为4.05±0.63%。
