Luminescent vibrios associated with mortality in pond-cultured shrimp penaeus monodon in the Philippines: Species composition
(Japanese Society of Fish Pathology, 2001)Heavy mortalities due to luminescent vibriosis have been observed among pond-cultured Penaeus monodon shrimp in the Philippines. The species composition of luminescent Vibrio associated with mortalities was determined. A ... -
Occurrence and histopathogenesis of a didymozoid trematode (Gonapodasmius epinepheli) in pond-reared orange-spotted grouper, Epinephelus coioides
(Elsevier, 2001)A didymozoid trematode encapsulated in the gills of orange-spotted grouper, Epinephelus coioides Hamilton, was observed in October 1997 and September 1999 among pond-reared fish in the Philippines. Capsule prevalence was ... -
Effect of dietary phosphorus and vitamin D3 on phosphorus levels in effluent from the experimental culture of rainbow trout (Oncorhynchus mykiss)
(Elsevier, 2001)Excessive phosphorus (P) levels in aquaculture effluents violate federally mandated limits and pose a serious threat to the freshwater environment. In rainbow trout culture, effluent P probably originates as fecal and ... -
Effect of dietary protein and lipid levels and protein to energy ratios on growth, survival and body composition of the mangrove red snapper, Lutjanus argentimaculatus (Forsskal 1775)
(Wiley-Blackwell, 2001)The approximate levels of dietary protein and energy that would sustain good growth and survival of the mangrove red snapper Lutjanus argentimaculatus (Forsskal) were determined in two feeding experiments. In the ... -
Dietary phosphorus requirement of juvenile milkfish, Chanos chanos (Forsskal)
(Blackwell Publishing, 2001)Seven isocaloric and isonitrogenous diets with graded levels of monopotassium phosphate to yield total phosphorus levels of 0.28 (no P supplementation), 0.43, 0.58, 0.73, 0.88, 1.03 and 1.18% were prepared and fed to five ... -
Culture and economics of wild grouper (Epinephelus coioides) using three feed types in ponds
(Elsevier, 2001)The performance of wild Epinephelus coioides juveniles was compared by feeding with live tilapia juveniles, fish by-catch, and formulated diet for 5 months in grow-out ponds. To minimize cannibalism, the groupers were ... -
Reproductive performance of hatchery-bred donkey's ear abalone, Haliotis asinina, Linne, fed natural and artificial diets
(Blackwell Publishing, 2001)Hatchery-bred donkey's ear abalone, Haliotis asinina, Linne broodstock were given diets consisting of natural food, seaweed (SW), Gracilariopsis bailinae, D1; combination of SW and artificial diet (AD), D2; and AD alone, ... -
Influence of various dietary synthetic carotenoids on bio-defence mechanisms in rainbow trout, Oncorhynchus mykiss (Walbaum)
(Wiley-Blackwell, 2001)This study examined the influence of different carotenoids on growth and some immune indices in rainbow trout. Six semipurified casein-based diets were formulated to contain one of three different carotenoids: astaxanthin, ... -
Production economics and marketing of mud crabs in the Philippines
(Asian Fisheries Society, 2001)The current price of mud crabs in the local market is relatively higher than fish and mollusks and is projected to increase in the world market. This increasing trend in domestic and export markets is expected to step-up ... -
Effect of prepared diet and vitamins A, E and C supplementation on the reproductive performance of cage-reared bighead carp Aristichthys nobilis (Richardson)
(Blackwell Publishing, 2000)Twenty-month-old bighead carp, Aristichthys nobilis (Richardson), were fed prepared dry diets for 20 months in cages in Laguna de Bay, Philippines, to determine the effect on reproductive performance. The experimental diets ... -
Transport of Scylla serrata megalopae at various densities and durations
(Elsevier, 2000)The optimal conditions for transport of Scylla serrata megalopae were determined. Loading densities of 50, 100 and 150 ind l−1 of hatchery-reared megalopae were studied over a 6-h simulated transport, including ... -
Runt-deformity syndrome in cultured giant tiger prawn Penaeus monodon
(Crustacean Society, 2000)A total of 24 morphological abnormalities associated with the Runt-Deformity Syndrome (RDS) is reported for the first time in 17- to 18-mo old F3 generation Penaeus monodon (>40 mm CL) belonging to ... -
Size and diel differences in activity patterns of Metapenaeus ensis, Penaeus latisulcatus and P. merguiensis
(Taylor & Francis, 2000)The nursery function of mangroves as shelter has been postulated to explain the positive correlation between shrimp catches and mangrove area. This study was undertaken to document shelter use and other activities in ... -
The yellow mangrove: its ethnobotany, history of maritime collection, and needed rehabilitation in the central and southern Philippines
(University of San Carlos Publications, 2000)Most mangrove reforestation program in the Philippines and elsewhere in Asia focus on the genus Rhizophora, hence there is a need to identify and develop planting and harvesting techniques for other mangrove species, ... -
Development and conservation of Philippine mangroves: institutional issues
(Elsevier, 2000)The decline of Philippine mangroves from half a million hectares in 1918 to only 120 000 ha in 1994 may be traced to local exploitation for fuelwood and conversion to agriculture, salt beds, industry and settlements. But ... -
Measures of egg quality in induced spawns of the Asian sea bass, Lates calcarifer Bloch
(Springer Verlag, 2000)The egg morphometry and lipid and protein components were determined in induced spawns (n = 14) of the sea bass, Lates calcarifer, to identify measures of egg quality. Based on fertilization and hatching rates, the spawns ... -
Growth regulation by insulin-like growth factor-I in fish
(Japan Society for Bioscience, Biotechnology, and Agrochemistry, 2000)Insulin-like growth factor-I (IGF-I) is a mitogenic polypeptide that plays an essential role in the regulation of development and somatic growth of vertebrates, mainly by mediating growth hormone actions. It has clearly ... -
The effects of diets on reproductive performance of eyestalk ablated and intact mud crab Scylla serrata
(Elsevier, 2000)The reproductive performance of female mud crabs was evaluated as affected by various diets. Dietary treatments were as follows: D1 — natural diet (mussel meat, squid, trash fish); D2 — combination ... -
Processed meat solubles, protamino aqua, used as an ingredient in juvenile shrimp feeds
(Society of Israeli Aquaculture and Marine Biotechnology, 2000)The nutritive value of processed meat solubles, Protamino Aqua, a by-product from slaughter-houses, was examined in a growth trial with juvenile tiger shrimp Penaeus monodon. Experimental diets were formulated to contain ... -
Why are Halophytophthora species well adapted to mangrove habitats?
(Springer Verlag, 2000)Halophytophthora species are commonly isolated from fallen mangrove leaves from early to late stages of decay. In this study we show that these organisms are well adpted to mangrove habitats as they have a wide tolerance ...
