Abstract:
This study was motivated by the need to find a
solution to poor egg quality and the resulting mass mortality of
hatchery-produced larvae of the tiger prawn, Penaeus monodon. The
approach adopted sought to improve the broodstock condition and determine
its effect on egg quality using rates of fertilization, hatching and
metamorphosis. Broodstock specimens were given four separate dietary
treatments (D1–D4), all of which comprised
squid and trash fish plus supplements. D2, D3 and D4 were supplemented with
bloodworm, bioencapsulated bloodworm and a commercial broodstock diet,
respectively. Tricalcic phosphate (Ca3(PO4)2)
was used to enrich the live bloodworm. The bioencapsulated ration performed
better than regular bloodworm and other diets. This was evident from the
bioencapsulation results which showed the highest rate of hatching, survival
of nauplii and larvae metamorphosing into zoea stage.
