Profile
Name of species/group : mud or mangrove crabs (Scylla spp.)
Primary potential : Aquaculture. There is limited scope for stock enhancement.
Once mud crab are through their larval stage they appear to have robust health. In many areas throughout Southeast Asia juvenile mud crabs are collected from the wild and stocked into ponds or enclosures for grow-out.
Once through the larval stage survival through grow-out is high, if ponds are stocked at appropriate densities. Mud crabs can grow from juvenile to adult size in 4-6 months, dependent upon species and water temperature, providing the potential for 2 crops (grow-out) per year.
Live mud crabs fetch market prices of around AUD10 per kg, whilst higher prices can be obtained for soft-shell mud crab in Asian markets from smaller crabs of 100-150 g. For crabs picked for crab meat for canning, a price of around AUD3 per kg is common. Premium prices, of around AUD20 per kg, can be obtained for hard shell crabs in excess of 1 kg for the banquet market in restaurants, with particularly high prices during the New Year and Chinese New Year periods.
In Indonesia and Philippines the price paid for crablets for farming is rising every year as the supply situation from the wild worsens.
Mud crabs are quite hardy organisms. Little is known of disease problems in the juvenile or grow-out phase of their culture. It is only during larval culture that susceptibility to bacteria has been identified.
Mud crabs (S. serrata) have a high fecundity, producing several million eggs per individual. They are easily bred in captivity, which means that selective breeding (e.g. for rapid growth) can be introduced in the near future.
Broodstock husbandry is simple.
Mud crabs are easily transported either as larvae in water, or dry once they have reached the crab stage.
