Economic evaluation of grow-out diets for Asian catfish Clarias macrocephalus (Gunther) production
(University of the Philippines in the Visayas, 2000)The economic feasibility of four grow-out diets for the Asian catfish Clarias macrocephalus was evaluated on a 1000 m2/crop basis. Hatchery-bred catfish juveniles with mean body weight (MBW) of 3.6 g and mean ... -
Changes in Na+, K+-ATPase activity and gill chloride cell morphology in the grouper Epinephelus coioides larvae and juveniles in response to salinity and temperature
(Springer Verlag, 2000)The activity of the enzyme Na+, K+-ATPase and morphological changes of gill chloride cells in grouper, Epinephelus coioides larvae and juveniles were determined 6–48 h after abrupt transfer from ambient ... -
Development of larval diets for milkfish (Chanos chanos)
(Blackwell Publishing, 2000)This study aimed to develop nutritionally balanced and costeffective processed diets for milkfish larvae (Chanos chanos). Two larval diets (feed A and feed B) were formulated and prepared to contain 45% protein and 10% ... -
Co-management in marine fisheries in Malalison Island, central Philippines
(Taylor & Francis, 2000)This study, conducted from November 1995 to February 1996, describes the evolution and impact of fisheries co-management arrangements in a coral reef fishing village at Malalison Island, central Philippines. The island is ... -
Isolation, cDNA cloning, and growth promoting activity of rabbitfish (Siganus guttatus) growth hormone
(Elsevier, 2000)We report the isolation, cDNA cloning, and growth promoting activity of rabbitfish (Siganus guttatus; Teleostei; Perciformes; Siganidae) growth hormone (GH). Rabbitfish GH was extracted from pituitary glands under alkaline ... -
Growth, agar yield and quality of selected agarophyte species from the Philippines
(Walter de Gruyter, 2000)Three local agarophyte species (Gracilaria firma, Gracilaria sp. and Gracilariopsis bailinae) were grown under controlled outdoor flow-through culture conditions. Growth rates and agar characteristics of the three species ... -
Elemental sulfur in the gills of the mangrove mud clam Anodontia edentula (Family Lucinidae)
(National Shellfisheries Association, 2000)Different sizes of the mangrove mud clam Anodontia edentula were collected from the mangroves in Brgy. San Roque in Estancia, Iloilo, central Philippines, and the mantle, gill, and foot tissues were analyzed for ... -
Gill structure, anatomy and habitat of Anodontia edentula: Evidence of endosymbiosis
(National Shellfisheries Association, 2001)Surveys and interviews were conducted to determine sources and habitat of Anodontia edentula. Results showed that they inhabit muddy substrate of mangrove areas or the adjacent mudflats, burying at 20-60 cm deep in the ... -
Collection of the clam Anodontia edentula in mangrove habitats in Panay and Guimaras, central Philippines
(Kluwer Academic Publishers, 2002)The mangrove clam Anodontia edentula is highly prized in the Philippines for its flavor and large size. Because this infaunal species is found down to one meter deep in mangrove areas, harvesting the clam reportedly damages ... -
Community fishery resources management on Malalison Island, Philippines: R & D framework, interventions, and policy implications
(Taylor & Francis, 2000)In 1991, the Aquaculture Department of the Southeast Asian Fisheries Development Center launched a community-based fishery resources management project on Malalison Island, in central Philippines, to help conserve the ... -
Commercial evaluation of monosex pond culture of the mud crab Scylla species at three stocking densities in the Philippines.
(Elsevier, 1999)The effects of three levels of stocking density (0.5, 1.5 or 3.0 m−2) and monosex culture (male or female) on the growth, apparent feed conversion ratio (FCR), survival, and production of mixed species of mud ... -
Use of copepod nauplii during early feeding stage of grouper Epinephelus coioides
(Japanese Society of Fisheries Science, 1999)Newly-hatched Epinephelus coioides larvae were stocked in five 5-ton tanks at an initial density of 25, 000 ind/tank. Copepod nauplii were propagated in four of these tanks by inoculating various densities (20 to 80 ind/l) ... -
Feed ration for different sizes of wild and hatchery-bred milkfish (Chanos chanos Forsskal)
(Wiley-Blackwell, 1999)Intensified production of fish involves stocking at high densities and the use of artificial feeds. These practices result in eutrophication and environmental degradation mainly because of feed wastage and fish excreta. ... -
Distribution pattern of shrimps and fish among Avicennia and Rhizophora microhabitats in the Pagbilao mangroves, Philippines
(Elsevier, 1999)For sustainable management of mangrove ecosystems, there is a pressing need to increase our knowledge of fish and invertebrates associated with this system. This study sampled microhabitats (89–258 m2) ... -
Analysing the diel feeding patterns and daily ration of Nile tilapia, Oreochromis niloticus (L.), in Laguna de Bay, Philippines
(Wiley-Blackwell, 1999)Cage cultured Nile tilapia, Oreochromis niloticus, were sampled at a commercial set-up on two occasions in 1995 in Laguna de Bay, Philippines, each time over a 24 h cycle. The stomach content weights were averaged for each ... -
Sargassum Studies in Currimao, Ilocos Norte, Northern Philippines II. Seasonal Variations in Alginate Yield and Viscosity of Sargassum carpophyllum J. Agardh, Sargassum ilicifolium (Turner) C. Agardh and Sargassum siliquosum J. Agardh (Phaeophyta, Sargassaceae)
(Walter de Gruyter, 1999)The yield (%) and viscosity (cps) of alginate from Sargassum carpophyllum, S. ilicifolium and S. siliquosum collected along the inter- and subtidal zones of Currimao, Ilocos Norte were determined monthly for a period of ... -
Interaction between dietary levels of calcium and phosphorus on growth of juvenile shrimp, Penaeus monodon
(Elsevier, 1999)Information on the dietary phosphorus (P) requirement is essential in the formulation of a cost-effective and low-pollutant feed. Ten isonitrogenous (40% CP) casein–gelatin-based diets containing five graded levels of P ... -
A combined upflow and fluidized sand filter for recirculating systems
(Society of Aquaculture Engineers of the Philippines, Inc., 1999)The process required and options for water treatment in recirculating systems have been clearly identified. The four most critical processes are: (1) solids removal, to take out fecal waste, uneaten feed, excess bacterial ... -
