Crabs

This manual includes the biology of the 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. This manual builds upon the 2nd edition of Biology and hatchery of mud crabs Scylla spp. published in 2008.

A 30-page manual detailing the different diseases of mud crab and the corresponding prevention/control measures.

Freshwater habitats and biodiversity in the Arabian Peninsula are unique and highly valued for the essential role they play in people's survival, as well as that of its native flora and fauna. This project aims to provide an accurate picture of the present conservation status and distribution of Arabian freshwater species, as well as to identify the main threats that affect them and action requirements for their successful long term conservation.
