Biology and hatchery of mangrove crabs Scylla spp. Quinitio, Emilia T.; Parado-Estepa, Fe Dolores; dela Cruz-Huervana, Joana Joy This 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.

Diseases of juvenile and adult mud crab Scylla spp. in the Philippines Tendencia, Eleonor; Cabilitasan, Ma. Venuz C.; Tobias-Quinitio, Emilia This manual aims to provide updated information on the diseases of mud crabs initially authored by Lavilla-Pitogo and dela Peña (2004). It includes the name of the disease, causative agent, stages affected, effects on mud crab and methods of prevention and control. Except for the infectious diseases caused by viruses, which can be detected through molecular methods, most of the diseases can be visually diagnosed. Photographs of the external and internal anatomy of a normal mud crab, including the different sexes and species are included to help readers differentiate a normal from a diseased mud crab. A 30-page manual detailing the different diseases of mud crab and the corresponding prevention/control measures.

Health management of milkfish Chanos chanos Cruz-Lacierda, Erlinda R.; Estante, Erish G.; de Jesus-Ayson, Evelyn Grace T.; Corre, Valeriano L., Jr. This monograph provides updated information on diseases of marine and brackishwater cultured milkfish in the Philippines. The information presented here is largely based on the results of a three-year research project on milkfish at the University of the Philippines Visayas funded by the Department of Science and Technology (DOST). The project involved surveillance and monitoring of hatchery, nursery and grow-out operations for occurrence of diseases as well as on disease diagnosis, prevention and control. Previously documented reports in the Philippines and in other documents, both published and unpublished, are also included in this monograph. The diseases are discussed on a culture phase basis, that is, disease problems encountered in hatchery-reared larvae and fry are listed first, followed by diseases observed in fingerlings and juveniles grown in nursery and grow-out culture areas, and adult stages maintained in broodstock facilities. Information regarding the causative agent, diagnostic procedures, and methods of prevention and control for each disease are provided, if available.
