Notes:
A prepared dry feed containing bloodworm meal Glycera chirori Izuka and oyster meal Crassostrea rivularis Gould, together with a natural diet consisting of G. chirori and shelled C. rivularis (1:1 ratio) and a mixed diet consisting of the prepared dry feed and the natural diet in equal proportion were evaluated as broodstock diets for female Pacific white shrimp Litopenaeus vannamei- (Boone). Results showed that shrimp fed the prepared dry feed gave higher maturation ratio and significantly higher hepatosomatic index (HSI) values (P 〈 0.05) than those fed the natural diet and the mixed diet. The prepared dry feed and the mixed diet induced higher total spawn numbers and significantly higher average daily spawns per female than the natural diet (P 〈 0.05), while the gonadosomatic index (GSI) values and fecundity (eggs per spawn) were not significantly affected by these diets. Results of this study showed that both the prepared dry feed and the mixed diet outperformed the natural diet to improve the spawning performance of female L. vannamei, and that using G. chirori meal and C. rivularis meal as the main ingredients of the prepared dry feed would be an effective way to promote the broodstock nutrition.
