水温和盐度对长牡蛎"海大1号"早期生长发育的影响
Effect of temperature and salinity on embryonic development, growth, survival, and setting of the Pacific oyster "Haida No.1" larvae
摘要
Abstract
This study examined the effect of temperature/salinity on embryos and larvae to verify the favorable and optimal temperature and salinity for the Pacific oyster "Haida No.1." The highest hatchability of fertilized eggs was 90% under the salinity 30–35. The salinity ranges 20–35, 20–35, and 20–35 were suitable and 20–30, 20–25, and 25–30 were optimal for the growth, survival, and setting of larvae, respectively. The temperature ranges 20–30°C, 20–25°C, and 20–30°C were suitable and the temperatures 30, 25, and 30°C were optimal for the growth, survival, and setting of larvae, respectively. When the temperature reached 35°C, all larvae were dead. The results obtained in this study will contribute to the improvement of the efficiency of mass aquaculture of the Pacific oyster "Haida No.1" larvae.关键词
