Mud crab

Why mudcrab culture?                                                                    

  • High demand in local and export markets
  • Large and good taste
  • Polyculture with milkfsh, tilapia or siganids
  • Easy to transport
  • Culture in mangroves
  • Investment for people’s cooperatives and fisherfolk organizations with tenure of mangrove area

SEAFDEC/AQD’s work on mud crab

Studies on mud crab at the SEAFDEC/AQD started in 1977, but were soon discontinued to give way to a priority shrimp species, Penaeus monodon. Studies were resumed in 1997 in collaboration with Australian Centre for International Agricultural Research (ACIAR) mainly to develop seed production and improve farming techniques. The project ran for 3 years.  A collaborative four-year project was later funded by the European Union in 2002 for the culture and management of Scylla species. This involved not only SEAFDEC/AQD but the University of Wales Bangor (U.K.), University of Gent (Belgium), and Can Tho University (Vietnam). The main objective was to improve the reliability and economic viability of mud crab hatchery and nursery production for mangrove-pond aquasilviculture production systems and stock enhancement. The Government of Japan Trust Fund partially funded the study on the domestication of mud crab in 2007 and recently on its selective breeding.

Grow-out studies on mud crab culture started in 1981 when researchers first tried different stocking densities. Two years later,  trials on polyculture of mud crab with milkfish were conducted. In 1995, SEAFDEC/AQD initiated studies on mud crab culture in mangrove pens in Panay Island. Then trials on mud crab monoculture in tidal flats with existing mangroves were verified in various places in the country. A study was conducted to evaluate the effects of crab net pen systems on mangrove (Fig. 1) macroflora, and the replacement of dietary fish with low-cost pellets.

In 2007, a 30-month project on Enhancing the Adoption of Mud Crab Technology in Northern Samar was implemented under the Community Agricultural Technologies Project of ACIAR. The framework was based on the Institutional Capacity Development on Sustainable Aquaculture of SEAFDEC where science-based technologies are disseminated to coastal communities, Local Government Units and other stakeholders.

The various collaborations and the continuous activity on seed production enabled SEAFDEC/AQD to package mud crab technologies, conduct local and international training courses and on-site technology demonstrations, and publish extension manuals and scientific publication. Mud crab culture has also been one of the activities under the SEAFDEC/AQD’s Agree-Build-Operate-Transfer program and Institutional Capacity Development for Sustainable Aquaculture, which is meant to disseminate science-based aquaculture technologies to stakeholders.
