Blue swimming crab hatchery production

Abstract

Portunus pelagicus, commonly known as the blue swimming crab (BSC), is a species of Portunid crab that is widely distributed in the coastal and estuarine areas of the Indo-Pacific Region, including the Philippines. It is a highly important commodity that supports the livelihood of smallscale fisherfolk in many coastal communities in the country.

Its natural stock in major fishing grounds, however, has become overexploited due to the increasing demand from both domestic and international markets. The high fishing pressure, coupled with urbanization, has also resulted in the degradation of the species’ natural habitat.

It is therefore imperative that stocks be replenished to sustain market demand for blue swimming crabs. Seed production is one of the ways to ensure the sustainability of this resource.

This training module aims to provide participants with knowledge and skills on hatchery techniques for seed production and methods for stock enhancement of blue swimming crabs.
