ABSTRACT

An 8 weeks experiment was conducted to determine the effects of two fish meal protein level diets (Diet A and Diet B) on the growth and survival rates of 36 families of Penaeus monodon. The results showed that significant differences were observed in the weight gain of different P. monodon families fed with the same diet(P<0.05). The AGR (absolute weight gain rate) of the fastest weight gain families was 97.16% and 95.46% higher than that of the slowest weight gain families fed with Diet A and Diet B, respectively, but the order of weight gain of different families in the different diet groups was not the same. The average survival rates of P. monodon fed with different diets were significantly different (80.59% and 77.88%, respectively). The order of survival rate of different families in the different diet groups was not the same, either. There were significant differences(P<0.05) in production performance among families in different feed groups. The highest yield of families in Diet A group and Diet B group was 100% and 124.44% higher than that of the lowest families, respectively. The production of No.10 family and No.6 family ranked the top two at two dites. Therefore, the potential for selection for growth and survival is available and genetic materials for breeding selection are demanded in future.
