中文摘要:
      九孔鲍摄食人工饲料的盐度范围为 2 0~ 38,其中较适宜的盐度范围为 2 5~ 35 ,在此盐度范围内 ,小规格鲍 (平均壳长 1 .30cm ,平均体重 0 .37g)的壳长日增长为 91 .5~ 1 0 2 .3μm ,日增重为 8.6 0~ 1 2 .5 5mg ;大规格鲍 (平均壳长 2 .6cm ,平均体重 2 .3g)的壳长日增长为 5 6 .30~ 81 .80 μm ,日增重为 1 2 .6 8~ 2 2 .48mg ,其最适生长的盐度为 30~ 35 ,存活率为 97%~ 1 0 0 %。九孔鲍所能忍受的盐度变化范围为 :日渐变幅度 (2 4h内盐度变化 )为 1 6 ;日突变幅度 (瞬间变化 )为 1 4 ,这些研究结果对开展九孔鲍人工养殖将有一定的参考意义。 更多还原
英文摘要:
      This paper report the performance for the intake growth and survival of abalone, Haliotis diversicolor supertexta fed artif icial diets under different salinity conditions. The results showed the salinity range for H . diversicolor supertexta fed with artificial diets was from 20 to 38, so the suitable salinity for growth ranged f rom 25- 35, and the optimum salinity was 30~ 35, respectively. In the condition of the above salinity, the daily growth in shell length and in body weight of small juveniles ( Mean shell length= 1. 3cm and mean body weight= 0. 37g , initial size) was 91. 5- 102. 3..m, 8. 6- 12. 55mg. The same for the large juveniles ( Mean shell length= 2. 6cm and mean body weight= 2. 3g) , it was 56. 3- 81. 8..m, 12. 68- 22. 48mg. The trail also showed the endurance of H . diversicolor supertexta on daily salinity change by degress ( within 24h) was 16; and the endurance on sudden change of salinity ( within 24h) was 14.
