Larval culture and rearing techniques of commercially important crab, Portunus pelagicus (Linnaeus, 1758): Present status and future prospects

Abstract

For consistent seed production, better understanding of larviculture and rearing techniques is crucial to maximize production of high quality and healthy larvae of cultured species. There are many different larval rearing methods in the world due in part to the geography, climatic patterns, species culture, and feeding regimes. This review provides available information on the present status of hatchery techniques in aspect of larval production, identifies husbandry techniques, recognized the main bottlenecks of current hatchery operations and identify likely future technique for consistent production of blue swimming crab, Portunus pelagicus. It is important to simplify larval rearing methods to develop easy-to-use and efficient systems for the mass rearing of healthy crabs.The information on this review will be useful as a guideline to culture others Portunid crab as well as a reference to the academician, aqua-culturist, and the industry that indirectly support the sustainable aquaculture development for P. pelagicus crab.
