_b _b _c _aIntroduction While there are more than 6,700 identified species of crabs, there are mostly only four mud crab species that commercial fisheries and aquaculture production focus on for distribution, namely Scylla Serrata, S. tranquebarica, S. paramamosain, and S. olivacea (Shelley & Lovatelli, 2011). The bigeest end-user of vrabs is the foodservice industry. The rise of said industry and the increasing demand for the product is predicted to catapult the global Crab market to 3.7 Million Metric Tonnes by the end of 2026 Research and Markets (2020) determined the primary driving force of the global crab market to be the rising per capita seafood consumption, rising incomes, and increased urbanization. Among the species above of mud crab commercially produced, the Philippines is among the countries that make Indo-Pacific Swamp Crab, or the Scylla Serrata. Specifically, the Philippines is one of the biggest producers of S. Serrata in the Indo-pacific region. In monoculture or polyculture with milkfish or shrimp, mud crabs fetch high prices form domestic and international markets (Agbayani, 2001; Agbayani et al., 1997). With the projected growth in demand, there is the following increase in mud crab culture businesses. In comparison with other types of aquaculture, mud crab culture still has many variants. The variants include feedstock collected from the wild and produced from a hatchery, varying farming systems, monoculture to polyculture, and farm sites, As a result, techniques, technologies, and principles have been developed based on the needs of farmers and even governments that wish to establish and sustain a mud crab aquaculture business or industry (Shelley & Lovatelli, 2011). For instance, in the Philippines, the farm sites for the aquaculture of mud crabs include aquaculture in ponds and mangroves or tidal flats. The means of production employed by domestic producers utilize chopped trash fish, animal hide or entrails, and snails are used as feed. After 4-5 months, marketable sizes (300-350 g) may be harvested and handpicked during low tide. A production yield of 1,200 kgs. They were maybe achieved by the producers with a survival of 70%. Typically, Return of Investment (ROI) is placed 60% and has a payback period of 1.4 years. In addition to crab culture, local producers of crabs utilize a technique called Mudcarb Fattening. This technique takes a minimum of 15 days and a maximum of 30 days, during which growers fatten lean crabs before they are sold for export. One of the standard features of mud crab fattening in ponds or mangroves is selective or progressive harvesting and restocking (Santos, n.d.). Although, there is a need to point out that, in crab culture, growers experience two unusual behaviors of crabs, as pointed out by Shelley & Lovatelli (2011). First, Cannibalism among mud crabs is a behavioral trait that is poorly understood but currently presents a significant problem for culturing them in open systems at anything other than density. Investigations into the influence of molting and even though crabs of different sizes and sex exhibited different responses to stimuli. By holding mud crabs in individual containers, as in fattening operations, survival can be dramatically improved compared with pond-reared crabs, where Cannibalism is prevalent. Second, the spawning migration of female mud crabs from the mangrove forests to offshore habitats has been well documented and seems to be a behavior shared by all Scylla. The spawning migrations of female S. Serrata into deep water, often kilometers offshore, was argued to provide an effective dispersal mechanism. About a month following the spawning migration, a migration of young crabs towards backlash water was reported in the Philippines, with vast numbers found in river mouths and along the shoreline. Swarms of young crabs were said sometimes to be left exposed on the mud during an ebb tide. Production and techniques aside, sales are integral in the mud crab business. According to Agbayani (2001), the marketing systems of mud crab producers in the Philippine use the 4 Ps marketing mix, while the distribution channels of mud crabs are similar to fish marketing. Limited quantities of crabs are sold in local markets. Restaurants, and at times, directly to consumers. Media advertising and promotions aimed at informing and attracting customers to patronize seafood products were very evident based on his study. The proponents of this study intend to determine the feasibility of mud crabs cultivation in San Juan Norte, Agoo, La Union. _u |
