Summary: | The genus Scylla is commonly known as mud crab or mangrove crab, inhabit muddy
substrate in estuaries and mangrove areas. Aquaculture of mud crabs is expanding due to
increasing demand on crab meats in Asia. Mud crab wholesale prices may exceed MYR
80+/kg during peak season, as many people consider it a delicacy. The study of egg
development crabs by applying alternate feeding technique are still poorly discovered. Hence, the study regarding egg development of mud crab by applying alternate feeding are
important in order to provide farmers with a consistent supply due to the shortage in
Malaysia and even other countries around the world. The study was conducted at Puncak
Innovasi Sdn. Bhd., Kampung Seri Lalang, Batu Enam, Kluang, Johor with the
Recirculation Aquaculture System (RAS). The source of brood stocks, female mud crab
Scylla olivacea had been provided by ABCrabs Trading, Kluang. Alternate feeds such as
squid, mussel, fish and cockle were fed in this study.The stages of ovarian maturity and the
weight of mud crabs were recorded as proxy of egg development because it is correlated to
the egg development. One-way ANOVA had been used to study the data collected. The
repeated measure ANOVA test showed that the mixed feeds did not give significant effect
on egg development of mud crab, Scylla olivacea |
