Fecundity, hatching rate and crab larvae quality of blue swimming crab, Portunus pelagicus, broodstock reared inearthen ponds, fed with different feeds, were studied for about 150 days. Results showed that average fecundity ofP. pelagicus broodstock fed with trash fish (569,842±243,173 eggs), shrimp feed (464,098±188,884 eggs), mixed feeds(544,875.3±169,357.3 eggs) and hatching rate (50.78±25.19%, 62.33±26.79% and 50.86±20.76%) were not significantly different(P>0.05). Zoea produced by female broodstock fed with mixed feeds had a significantly higher survival rate (89.47±5.03%,P |
