  • In mid-May and the beginning of August every year,the abundance indexes of both eggs/larvae and the juveniles were surveyed in the spawning sites and habitats of penaeid shrimp in the Bohai Bay,the relationship of the egg abundance index (S[t]) and the recruitment (R[t]) in Ricker Model is:R[t]=aS[t]e[-bS][t],and the obtained parameters are:a=29.2243,b=0.069,R[2]=0.47,P<0.005. The results indicated that the egg abundance of penaeid shrimp had the determinant effect on the recruitment and the environmental factors of the habitat,such as rainfall,wind,sunlight and runoff from the Yellow River,would also largely affect the survival rate of eggs and larvae as well as the recruitment.

The Study on Dynamic Characteristics of Egg Abundance and Recruitment of Penaeid shrimp (Penaeus chinesis) in The Bohai Bay

Abstract: In mid-May and the beginning of August every year,the abundance indexes of both eggs/larvae and the juveniles were surveyed in the spawning sites and habitats of penaeid shrimp in the Bohai Bay,the relationship of the egg abundance index (S[t]) and the recruitment (R[t]) in Ricker Model is:R[t]=aS[t]e[-bS][t],and the obtained parameters are:a=29.2243,b=0.069,R[2]=0.47,P<0.005. The results indicated that the egg abundance of penaeid shrimp had the determinant effect on the recruitment and the environmental factors of the habitat,such as rainfall,wind,sunlight and runoff from the Yellow River,would also largely affect the survival rate of eggs and larvae as well as the recruitment.
