Adult artemia as life feed for african catfish (Clarias gariepinus) fingerlings

Abstract

The study of soft-shell crab production culture technology was carried out in the marine hatchery University Malaysia Terengganu. The study was to determine the best temperature, photo period and salinity factors used to produced the soft-shell crab using mud crab (S. olivacea). The culturing was carried out in the culture tank with different set of salinity, photo period and temperature combinations. The size of the crabs, days of moulting and survival rate had been recorded. The statistical analysis that had been used in the study was using descriptive, One-Way ANOV A and the correlation in the Statistical Package of Social Science (SPSS) program. The experiment had show a succession in the production of soft-shell crabs using the mud crab. The result showed that there was no significant different between the six culturing tank due to the P-value higher than the significant level 0.05. Result also showing no significant different between the different set of salinity and photo period. Comparison had done to show the interaction with the survival of crabs. The Tank no.3, 4 and 5 culturing condition can be used as the reference for future study. The removing the pincer and walking legs also contribute to the succession of the soft-shell crabs production.
