A great deal of research into mud crab husbandry at academic levels and at more grassroot levels has been undertake in the Philippines. Esperanza A. Santos and Leah Charito T. Tambolero have written about a Bureau of Fisheries and Aquatic Resources – Fisheries Resource Management Project entitled Reviving a Coop: Rising Above Waters Through Mangrove Crab Culture. The coop also raised tilapia and prawns as secondary stocks. The authors report report: ‘After a full year implementation, the project provided substantial earnings for all the members of the coop. They hope that their learnings will be valuable lessons as well for those areas, families and people’s organizations interested to venture into mangrove crab culture.’
The Science and Development Network sumarises, and the New Agriculturalist reports on research to more closely integrate crab culture with sustainable mangrove management. From the introduction:
The rapid spread of aquaculture in recent decades has brought riches to some, ruin to many, exclusion to the poorest coastal dwellers, and environmental degradation. Scientists in the Philippines are adapting aquaculture to make it sustainable over the long term and suitable for small-scale, family-level operators. An innovative system of captive crab culture in live mangrove is being developed in the central Philippines and is now being verified and demonstrated on the southern island of Mindanao.
The Culture and Management of Scylla Species (CAMS) project was a collaboration among four institutions worldwide – the University of Wales (Bangor) in the United Kingdom, Artemia Reference Center of the University of Ghent in Belgium, Can Tho University in Vietnam, and SEAFDEC/AQD in the Philippines. The CAMS project has reported on aquasilviculture projects in the Philippines and Vietnam. The objective: To refine systems for integrated aquasilviculture of mud crabs within mangroves, specifically by reducing fish biomass requirement through low cost incomplete feeds and utilization of natural productivity. The aquasilviculture reports are available online.
