Mud crab hatchery and grow-out status in the Philippines
MetadataShow full item record
Interest in mud crab aquaculture is increasing throughout the Philippines because of its demand both in local and export markets. Mud crab culture started as low-density polyculture with fish or shrimp using wild crab juveniles and developed to monoculture in ponds and cages. Recently, an integrated mangrove-crab culture system has been practiced. Mud crab species commonly cultured are Scylla serrata, S. tranquebarica, and S. olivacea. The yearly increase in production from 1996 to 2000 (Table 1) may indicate a corresponding increase in the seed collection activity due to greater demand of seeds for stocking. According to many gatherers in the country, there has been a declining volume of all size-classes, from juveniles to adult crabs, gathered from the wild over the last decade. Hence, the development of a commercially viable hatchery technology can play an important role in promoting sustainable crab aquaculture and fisheries management.

Aquaculture, 2018 - ElsevierThe increasing global demand for mud crabs (genus Scylla) and threats to the wild populations highlight the urgency of fully rearing them in captivity. Despite considerable progress in mud crab production, most crab farms still rely heavily on wild-caught crablets and juveniles while the low and inconsistent success rates of larviculture remain as the main bottleneck impeding the development of mud crab aquaculture. Over the years, numerous studies have been conducted to determine the optimum larval rearing parameters, the ontogenic changes in digestive function and feeding behaviour, and the diets for different larval stages. These data, however, are dispersed and not summarised to inform culture practices. This review provides an update on the current progresses and to pinpoint the gaps in knowledge regarding mud crab larval rearing. We include all four mud crab species under the genus Scylla, i.e. Scylla serrata, Scylla olivacea, Scylla tranquebarica and Scylla paramamosain. Knowledge compiled in this review serves as an important guideline for prospective mud crab larviculture. Future research should gear towards filling in the gaps in our knowledge to advance mud crab larval rearing, thus fully incorporating mud crab into the aquaculture sector.

Series: Aquaculture extension manual; No. 34This manual includes the biology of crab (Scylla serrata, S. tranquebarica, and S. olivacea), and describes principles and procedures for spawning the mature crabs and rearing the zoea to ‘fly’ size crabs. It focuses on the hatchery rearing of S. serrata as the farming of this species is more economically viable than the two other species. The techniques may be modified depending on the conditions or problems encountered in a specific site.
