摘    要:为探讨盐度、pH对云纹石斑鱼Epinephelus moara胚胎发育和仔鱼活力的影响,采用单因子实验的方法,在水温22±0.2℃条件下,将受精卵在不同盐度(5、10、15、20、25、30、35、40和45)、不同pH(5.5、6.0、6.5、7.0、7.5、8.0、8.5、9.0和9.5)下孵化,观察比较其孵化率HR、畸形率DR以及对初孵仔鱼活力和仔鱼培育周期的影响。并在上述设定条件下,进行了初孵仔鱼耐受试验,测定其存活率SR及生存活力指数(SAI)。结果表明,云纹石斑鱼胚胎发育的最低和最高临界盐度分别为10和45,最低和最高临界PH分别为6.O和9.5;盐度、PH的适宜范围分别是20~40、6.5~9.0,最适范围分别是30~35、7.5~8.0。仔鱼生存盐度、pH的适宜范围分别是20~35、6.0~9.0,最适范围分别是25~30、7.5~8.0。

关 键 词:云纹石斑鱼  盐度pH  胚胎发育  生存活力指数

Abstract:Kelp bass Epinephelus moara, a fast growing and commercially valuable marine fish, is considered as a species of the highest potential for marine net cage culture in thetemperate seas along the coast of Northeast Asia. It has been investigated intensively for aqua culture during the past several decades in a number of countries. However, little is known a- bout its environmental requirements. In this study, the environmental impact on the embryonic development and the survival activity index (SAI) of the kelp bass larvae was investigated under salinity of 5, 10, 15, 20, 25, 30, 35, 40 and 45, and pH of 5.5, 6.0, 6.5, 7.0, 7.5, 8.0,8.5, 9.0 and 9.5, with water temperature of (22±0.2)℃. The results indicated that the mini mum and maximum saliny for the embryonic development of kelp bass was 10 and 45, the mini mum and maximum pH as 6.0 and 9.5, respectively. Based on the development time, hatching rate and deformity rate of the animal, the suitable salinity range was 15-40 , and 6.5-9.0 for pH, and the optimal salinity range was 30-35, and 7.5-8.0 for pH. Salinity 20-35, and pH 6.0- 9.0 were suitable for larvae survival, and the optimums were 25-30 for salinity, and 7.5-8.0 for pH, respectively.
Keywords:Kelp bass Epinephelus moara Salinity pHEmbryonic development Survival activity index (SAD
