Strategies to reduce disease incidence in mud crab culture
Amar, Edgar C.; ; ; Tendencia, Eleonor ; Faisan, Joseph P., Jr. (Aquaculture Department, Southeast Asian Fisheries Development Center, 2017)
Mud crab hatchery suffers from low survival due to susceptibility to bacterial infection in the early larval stages among many causes. Despite food safety issues, antibiotics continue to be used in the absence of effective ... -
Pilot scale production of pellets suitable for mud crab Scylla serrata
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2017)Studies were conducted towards the pilot scale production of stable and nutritionally adequate pellets suitable for mud crab Scylla serrata to help in efforts to increase mud crab production in the Philippines. Preliminary ... -
Nursery and grow-out feeding management of mud crab farmers in the Philippines: Santeh experience
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2017)Mud crab (Scylla serrata) farming has been one of the means of livelihood of many Filipino farmers in coastal areas, specifically in Southern Luzon and Visayas. Nursery and grow-out operations in these areas vary in terms ... -
Evaluation of the bioremediation capacity of the polychaete, Marphysa mossambica (Peters, 1854) in pond sediments
Mandario, Mary Anne; ; (Aquaculture Department, Southeast Asian Fisheries Development Center, 2017)
Marphysa mossambica is commonly found in brackishwater ponds and is an important natural food for cultured stocks particularly mud crabs. To understand the burrowing activity of polychaete, survival and capacity to ... -
Growth, survival, proximate and fatty acid composition of sandworm Perinereis quatrefagesi (Grube, 1878) fed variable feed types
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2017)Sandworm Perinereis quatrefagesi has been used as feed for crustacean broodstock due to its reproductive-enhancing properties particularly protein and highly unsaturated fatty acids (HUFAs). Juvenile sandworms collected ... -
Private sectors perspectives: Problems and constraints of the mud crab grow-out industry
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2017)Mud crab aquaculture industry in the province of Capiz received much attention after production constraints due to diseases were encountered by the prawn industry. Fishpond operators sought for an alternative high value ... -
Adoption of modified commercial scale mud crab hatchery and nursery systems in Alaminos City, Pangasinan
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2017)Pangasinan’s vast fishpond and mangrove areas have not been fully tapped for mud crab (Scylla serrata) production. The main reason identified for this is the limited supply of crab seedstock. At present, there is no reliable ... -
Nursery culture of mud crab Scylla serrata fed diets supplemented with trytophan at two stocking densities
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2017)Cannibalism has been recognized as one of the major problems in crab culture. The use of dietary tryptophan (TRP) that has been reported to reduce cannibalism in crabs under laboratory conditions was verified in pond nursery ... -
Management strategies for grow-out culture of mud crab
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2017)There is an increasing interest in mud crab farming because of the growing demand for mud crab in domestic and international markets. Different methods for rearing crabs in ponds, pens and cages have evolved through several ... -
Morphological deformities in mud crab Scylla serrata juveniles exposed to antibiotics during the larval stage
; Quinitio, Emilia T.; ; (Aquaculture Department, Southeast Asian Fisheries Development Center, 2017)
The effects of antibiotics on the survival, growth and external deformities of mud crab Scylla serrata larvae and juveniles were determined. Zoeae were exposed to 0, 3, 6, 9, 12 mgL-1 oxytetracycline (OTC) and ... -
Induction of molting in hatchery-reared mud crab Scylla serrata juveniles through temperature manipulation or autotomy
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2017)The effects of water temperature and autotomy of chelipeds on growth, survival and molting of mud crab, Scylla serrata, juveniles were investigated under laboratory conditions in separate experiments. Hatchery-produced ... -
Initiatives on mud crab culture at the Palawan Aquaculture Corporation
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2017)Mud crab (Scylla spp) has long been a prime commodity in both local and global market and is regarded as one of the important high-value crustacean species produced in the Philippines.
