Abstract: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.
