Evaluation of the bioremediation capacity of the polychaete, Marphysa mossambica (Peters, 1854) in pond sediments
(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
(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. Decades ago, its culture basically ... -
Mud crab production trials at the College of Fisheries and Marine Sciences, Aklan State University, New Washington, Aklan
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2017)Two hatchery and nursery trials have been conducted at the College of Fisheries and Marine Sciences, Aklan State University (ASU) for the Multi-species Hatchery and Fishfarm Project from August to September 2014 and April ... -
Mud crab Scylla serrata hatchery operation
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2017)The initial exposure of the Santos family in aquaculture was the culture of milkfish (Chanos chanos) and mud crab (Scylla serrata) in brackishwater pond in Quezon. The milkfish fry were obtained from our own milkfish ... -
Updates on the larviculture of mud crab at SEAFDEC/AQD
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2017)Although the mud crab (Scylla serrata) hatchery technology has been developed, issues such as high cost of production due to the need for additional facilities and labor for natural food culture, inconsistent survival rate ... -
High throughput RNA sequencing reveals temperature tolerance mechanisms in Scylla serrata
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2017)The effects of increasing temperature from global climate change threaten the sustainability and production of mud crabs from farms and wild populations in mangroves. Adaptation of mud crab populations to temperature stress ... -
Population structure of Scylla serrata from microsatellite and mtDNA markers
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2017)Determination of the population structure and connectivity of natural populations of Scylla serrata are useful tools for decision making related to conservation and management efforts of this species. They provide important ... -
