摘  要:
为确定拟目乌贼发育生长最佳温度条件,采用单因子试验研究了不同温度(15、18、21、24、27、30、33℃)对拟目乌贼胚胎发育及幼体生长的影响.结果表明:不同温度对拟目乌贼胚胎发育及幼体影响显著(P<0.05).胚胎发育适宜温度为21~30℃,最适温度为24℃.最适温度下孵化率达(93.3±2.9)%,培育周期为(24.33±0.58)d,孵化周期为(6.00±1.00)d,卵黄囊完全吸收率为(96.4±3.1)%,初孵幼体体质量为(0.258±0.007)g.有效积温模型为N=284.42/(T-12.57).幼体生长适宜温度为21~30℃,最适温度为24~27℃.最适宜温度下幼体存活率达70.0%~73.3%,特定生长率为2.4%~3.8%.

摘  要:
A single-factor experiment was conducted to study the effects of different temperature (15,18,21,24,27,30,and 33℃) on the embryonic development and larval growth of Sepia lycidas,aimed to search for the optimum temperature for the development and growth of S.lycidas. The results showed that temperature had significant effects on the embryonic development and larval growth of S.lycidas(P
