Genomic polymorphism in symbiotic populations of Photobacterium leiognathi
(Blackwell Publishing, 2004)Photobacterium leiognathi forms a bioluminescent symbiosis with leiognathid fishes, colonizing the internal light organ of the fish and providing its host with light used in bioluminescence displays. Strains symbiotic with ... -
Mass mortalities associated with viral nervous necrosis in hatchery-reared sea bass Lates calcarifer in the Philippines
(Ministry of Tropical Agricultural Research Centre, 2004)Viral nervous necrosis (VNN), also known as viral encephalopathy and retinopathy (VER), is an emerging disease affecting larvae and juveniles of many farmed marine fish species in Asia, Australia, Europe and North America. ... -
Effects of low nitrogen-phosphorus ratios in the phytoplankton community in Laguna de Bay, a shallow eutrophic lake in the Philippines
(Springer Verlag, 2004)The effects of low nitrogen-phosphorus ratios on microalgae from a large eutrophic freshwater lake in the Philippines were investigated. Natural microalgal populations from Laguna de Bay, the largest lake in the Philippines, ... -
Mass mortality of hatchery-reared milkfish (Chanos chanos) and mangrove red snapper (Lutjanus argentimaculatus) caused by Amyloodinium ocellatum (Dinoflagellida)
(Elsevier, 2004)Outbreaks of heavy infestation by the parasitic dinoflagellate Amyloodinium ocellatum in hatchery-reared milkfish (Chanos chanos) and mangrove red snapper (Lutjanus argentimaculatus) caused 100% mortality events in hatcheries ... -
Tryptophan requirement of juvenile Asian sea bass Lates calcarifer
(Blackwell Publishing, 2004)The dietary requirement of tryptophan for juvenile Asian sea bass (Lates calcarifer Bloch) was studied. The juveniles (mean initial weight, 5.30 ± 0.06 g) were given semi-purified test diets containing fish ... -
Partial replacement of fishmeal by defatted soybean meal in formulated diets for the mangrove red snapper, Lutjanus argentimaculatus (Forsskal 1775)
(Blackwell Publishing, 2004)This study was conducted to evaluate the effect on growth and feed efficiencies of the mangrove red snapper (Lutjanus argentimaculatus) when dietary fishmeal is partially replaced by defatted soybean meal (DSM). In the ... -
Fishing cooperatives’ participation in managing nearshore resources: the case in Capiz, central Philippines
(Elsevier, 2004)This study documents the resource management initiatives undertaken by fishing cooperatives in Capiz, central Philippines and examines the conditions and the socioeconomic determinants that persuade members to assume ... -
Enhancement of innate immunity in rainbow trout (Oncorhynchus mykiss Walbaum) associated with dietary intake of carotenoids from natural products
Amar, Edgar C.
; ; ; (Elsevier, 2004)
The effects of orally administered carotenoids from natural sources on the non-specific defense mechanisms of rainbow trout were evaluated in a nine-week feeding trial. Fish were fed four diets containing either β-carotene ... -
Investigation of some components of the greenwater system which makes it effective in the initial control of luminous bacteria
Tendencia, Eleonor; (Elsevier, 2003)
Two components of the greenwater system, the tilapia water and Chlorella, were investigated separately for their effect on the population of luminous bacteria. For the investigation of tilapia water, Tilapia hornorum was ... -
Water quality and holding capacity of intensive and semi-intensive milkfish (Chanos chanos) ponds
(Elsevier, 2003)This study determined the holding capacity of semi-intensive and intensive milkfish ponds and water quality in relation to fish biomass and feed input. Six units of 1000 m2 brackishwater ponds were used, three ... -
Nitrogen and phosphorus digestibility and excretion of different-sized groups of milkfish (Chanos chanos Forsskal) fed formulated and natural food-based diets
(Blackwell Publishing, 2003)This study determined the digestibility of nitrogen and phosphorus, and the excretion rate of different-sized groups of milkfish fed a commercial diet, a SEAFDEC formulated diet or lab-lab (natural food-based diet). Fish ... -

Response of bighead carp Aristichthys nobilis and Asian catfish Clarias macrocephalus larvae to free-living nematode Panagrellus redivivus as alternative feed
(Blackwell Publishing, 2003)The use of Panagrellus redivivus as live feed for bighead carp and Asian catfish larvae was tested. In experiment 1, carp larvae were given Artemia nauplii (control) or Panagrellus twice daily for 21 days. A third ... -
Diet and harvesting regimen for the production of mud crab Scylla olivacea in brackish water ponds
(Japanese Society of Fisheries Science, 2003)The effects of diet (fish bycatch or a mixed diet of 75% brown mussel flesh and 25% cooked cracked corn) and harvesting regimen (bimonthly selective harvesting, or single terminal harvesting) on growth, survival and ... -
Terrestrial leaf meals or freshwater aquatic fern as potential feed ingredients for farmed abalone Haliotis asinina (Linnaeus 1758)
(Blackwell Publishing, 2003)Three terrestrial leaf meals, Carica papaya, Leucaena leucocephala, Moringa oliefera and a freshwater aquatic fern, Azolla pinnata were evaluated as potential ingredients for farmed abalone diet. All diets were formulated ... -
Ontogeny of feeding apparatus and foregut of mud crab Scylla serrata Forsskål larvae
; Quinitio, Emilia T.; ; ; (Blackwell Publishing, 2007)
The development of the feeding apparatus of the mud crab Scylla serrata larvae was studied using electron microscopy for mandibles and light microscopy for other paired mouthparts and the foregut. The six paired mouthparts, ... -
Cell growth and nutritive value of the tropical benthic diatom, Amphora sp., at varying levels of nutrients and light intensity, and different culture locations
(Springer Verlag, 2007)Two series of experiments were conducted to determine suitable growth factors for the mass propagation of the local algal isolate Amphora sp. A higher growth rate of 0.2 doubling (μ) day-1 was attained at a lower ... -
Larviculture of marine species in Southeast Asia: current research and industry prospects
(Elsevier, 2003)The increased requirement for food fish, the lucrative market for expensive seafood, and the need to conserve marine resources, have motivated the rapid pace of larviculture research in Southeast Asia. Various research and ... -
Tank culture of Gracilaria heteroclada (Zhang et Xia)
