This study was carried out to determine the reproductive performances of wild and<br />

cultured female Giant freshwater prawn, Macrobrachium rosenbergii. This includes the<br />

comparison between fecundity, hatching rate, salinity stress test and larvae<br />

development (Larval Stage Index - LSI) between wild caught and cultured prawn.<br />

Three samples of wild berried female broodstock each were sampled from Manir River,<br />

Terengganu and commercial farm at Marang, Terengganu. Each of the broodstock<br />

was stocked in 20L of brackish water (12 ppt) and reared until hatching. The larvae<br />

produced were reared in the same condition as the broodstock. The result shows<br />

significant different between wild and cultured broodstock where the wild broodstock<br />

has higher fecundity and larvae hatching rate. LSI shows almost similar result between<br />

wild and cultured. The result from the stress test (15ppt) signified that the mortality<br />

of post larvae from cultured broodstock was higher than wild caught broodstock.<br />
