Pens

Mud crabs can be grown in pens installed in existing mangroves for up to 3 months. The pen can be rectangular, square or irregular shape and the size ranges from 500-1,000 m2. The use of net enclosures in mangroves offers an alternative to pond culture. It also promotes a better image for brackishwater aquaculture that had been linked to the historical clear-cutting of mangroves to make way to ponds. Lean crabs may also be fattened using pens set in mangroves within 30-45 days. Mud crab pen culture is recommended in sites with mature mangrove trees in lower part of the intertidal zone. Procedure: Enclose the selected area with bamboo slats or nets (durable enough that cannot be destroyed by crabs) …

Grow-out

Crabs are commonly cultured with fish in earthen brackishwater pond.  Cannibalism in crabs is reduced by lowering the stocking density and maximizing the space by stocking fish. Common combination of crab is milkfish. Crabs (15 g to 30 g) are stocked in the pond with fish and grown for 3 to 5 months. The culture period depends on the initial size of crabs and fish and the stocking density. Two or more crops may be done in a year, depending on the desired crab size at harvest. Procedure: Prepare pond using standard procedure. Grow natural food such as ‘lablab’, plankton and other natural food prior to stocking. Stock milkfish fingerlings at 2,000-3,000/ha and crab juveniles at 500-800/ha. Acclimate animals to …

Nursery

Nursery is the intermediate phase between hatchery and grow-out. Crabs with 0.6-1.0 cm carapace width (CW) (Fig. 1) are cultured to 1.5-2.0 cm CW in net cages installed inside the pond (Fig. 2), in a pond fenced/lined with nets (Fig. 3), or in a pond provided with net fence along the dikes (Fig. 4). Some farmers prefer bigger crabs than 1.5-2.0 cm for stocking so crabs are further grown to 3.0-4.0 cm (Fig. 5) in ponds lined or fenced with nets or dikes installed with net fence (Phase 2) prior to stocking in grow-out ponds. Phase 1 and 2 may be done one after the other separately or continuously using the same pond compartment. The culture period is 3-4 weeks …

Hatchery

Although the technology applies to all the three species of mud crab (Scylla serrata, S. tranquebarica, and S. olivacea) available in the Philippines, S. serrata or the giant/king crab has been the focus of culture in the hatchery/nursery and grow-out pond due to its economic viability. Procedure: Obtain healthy adult crabs 500-700 g for S. serrata and 320-500 g for S. tranquebarica and S. olivacea with orange ovaries (‘aligi’) and complete legs as source of broodstock from ponds or traders. Put crabs in an empty basin and pour seawater over them slowly.  Transfer crabs to basin containing 150 ppm formalin for 30 minutes to disinfect. Transfer crabs in tanks provided with sand substrate. Feed crabs with mussel, fish and/or marine …
