Feeding regimes in relation to reproduction and survival of ablated Penaeus monodon

Abstract

Pond-reared P. monodon were stocked in four 12-cu m flowthrough maturation tanks at 25 males and 50 females per tank; females were unilaterally ablated. The combinations of feeds for the morning and afternoon rations were pellet-pellet, frozen mussel-frozen mussel, frozen mussel-pellet, and frozen squid-pellet. Reproductive performance in terms of total number of spawnings, total number of eggs produced, total number of nauplii produced, average number of eggs per spawning and average hatching rate was best for the mussel-pellet combination followed by the mussel-mussel and squid-pellet rations. The all pellet diet gave the poorest results.
