Plantlet regeneration of Kappaphycus alvarezii var. adik-adik by tissue culture
(Springer Verlag, 2007)Three color morphotypes of Kappaphycus alvarezii var. adik-adik (brown, green and red) collected from a farming area in Tictauan Is., Zamboanga City, Philippines were used as explants in the study in order to micropropagate ... -
Formalin as an alternative to trifluralin as prophylaxis against fungal infection in mud crab Scylla serrata (Forsskål) larvae
(Blackwell Publishing, 2007)The toxicity of formalin and trifluralin to the larval stages of the mud crab Scylla serrata was compared in a static bioassay. Prophylactic doses of 5, 10, 15, 20 and 25 μg L−1 formalin and 0.05, 0.1, ... -
Prevalence of white spot syndrome virus (WSSV) in wild shrimp Penaeus monodon in the Philippines
(Inter Research, 2007)Prevalence of white spot syndrome virus (WSSV) was determined using polymerase chain reaction (PCR) methodology on DNA extracted from the gills of wild black tiger shrimp Penaeus monodon collected from 7 sampling sites in ... -
Nitrogen and phosphorus utilization in the cyanobacterium Microcystis aeruginosa isolated from Laguna de Bay, Philippines
(Springer Verlag, 2007)Phytoplankton supports fisheries and aquaculture production. Its vital role as food for aquatic animals, like mollusks, shrimp, and fish cannot be overemphasized. Because of its contribution as a food source for fish, the ... -
Reproductive performance, lipids and fatty acids of mud crab Scylla serrata (Forsskål) fed dietary lipid levels
(Blackwell Publishing, 2007)Natural food (NF, control), artificial diets (AD) containing total lipid levels of 10%, 12% and 14% (AD10, AD12 and AD14) and their combinations (AD10+NF, AD12+NF and AD14+NF) were fed for 112 days to pond-sourced ... -
Are mangroves worth replanting? The direct economic benefits of a community-based reforestation project
(Cambridge University Press, 2006)Competition for coastal land use and overexploitation have reduced or degraded mangrove coverage throughout much of their distribution, especially in South-east Asia. Timber production was the initial motivation for early ... -
Presence of snapper, seabass, and siganid inhibits growth of luminous bacteria in a simulated shrimp culture system
(Elsevier, 2006)The antibacterial effect of the presence of Tilapia hornorum against luminous bacteria in shrimp culture has been reported. This study investigates how the presence of commercially valued marine species such as seabass, ... -
Effect of shrimp biomass and feeding on the anti-Vibrio harveyi activity of Tilapia sp. in a simulated shrimp–tilapia polyculture system
(Elsevier, 2006)The efficiency of Tilapia hornorum to control luminous bacteria in a simulated shrimp farm environment has been reported. However, the effects of different factors such as feed input and the shrimp biomass were not taken ... -
Price relationships in Philippine milkfish markets: Univariate and causality analysis
(International Association of Aquaculture Economics and Management (IAAEM), 2006)Uncertainties and lack of information on milkfish product prices, along with production-related problems with inputs, generally constrain efficient resource use in milkfish grow-out operations. Milkfish growers complain ... -
Hatchery-produced milkfish (Chanos chanos) fry should be fed docosahexaenoic acid-enriched live food: A case of the difficulty in the transfer of improved aquaculture technology in the Philippines
(Ministry of Tropical Agricultural Research Centre, 2006)Levels of highly-unsaturated fatty acids, the most important nutritional factors in fry production of marine fish, were compared between hatchery-produced and wild-caught milkfish Chanos chanos fry. The most striking ... -
Microsatellite–centromere mapping in the Japanese eel (Anguilla japonica) by half-tetrad analysis using induced triploid families
(Elsevier, 2006)Genetic improvement of the Japanese eel (Anguilla japonica) can be achieved by artificially controlling its life cycle using recent advances in reproductive biology. In this study, we developed 43 microsatellite loci to ... -
The coral communities of Mararison Island, Culasi, Antique, Philippines
(University of the Philippines in the Visayas, 2006)An assessment of the extensive fringing reefs surrounding Mararison lsland, Culasi, Antique was undertaken in 1994 to 1996 and in 1998 to provide scientific basis for management and enhancement of the island s resources ... -
Growth and agar quality of Gracilaria heteroclada (Zhang et Xia) grown in a filter tank
(College of Agriculture, University of the Philippines Los Baños, 2006)Gracilaria heteroclada Zhang et Xia was grown in filter tanks to determine the growth, agar quality and uptake pattern of nitrogen and to observe the water quality in recirculating water system with seaweed. Rapid uptake ... -
Occurrence of Polysiphonia epiphytes in Kappaphycus farms at Calaguas Is., Camarines Norte, Phillippines
(Springer Verlag, 2006)This paper describes the occurrence of an epiphyte infestation of Kappaphycus farms in Calaguas Is. Camarines Norte, Philippines. In particular, percentage cover of ‘goose bump’-Polysiphonia and ‘ice-ice’ disease, and some ... -
Air breathing of aquatic burrow-dwelling eel goby, Odontamblyopus lacepedii (Gobiidae: Amblyopinae)
(Company of Biologists, 2006)Odontamblyopus lacepedii is an eel goby that inhabits both coastal waters and intertidal zones in East Asia, including Japan. The fish excavates burrows in mudflats but, unlike the sympatric amphibious mudskippers, it does ... -
Immunolocalisation of nervous necrosis virus indicates vertical transmission in hatchery produced Asian sea bass (Lates calcarifer Bloch)—A case study
(Elsevier, 2006)A probable vertical mode of piscine nodavirus transmission is reported in the present investigation based on a case of nodavirus associated larval mortalities in hatchery produced Asian sea bass. Polyclonal rabbit anti-SJNNV ... -
Comparison of fatty acid profile between cultured and wild-caught grouper Epinephelus coioides
(Japan Aquaculture Society, 2005)The lipid content and fatty acid composition were examined in the liver, eye, muscle, brain and intraperitoneal fat body (IPF) of hatchery-bred and wild-caught orange-spotted grouper, Epinephelus coioides. The cultured and ... -
