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 ... -
Feeding ecology of silverperch, Terapon plumbeus Kner, and the impact fish-pens in Laguna de Bay, Philippines
(Blackwell Publishing, 2000)Aquaculture is an important factor in the fishery of Laguna de Bay in the Philippines; fish-pens and net-cages covered ≈10% of the lake surface in the late 1990s. The present study was carried out to assess the possible ... -
Survival of captive milkfish Chanos chanos Forsskal broodstock subjected to handling and transport
(Wiley-Blackwell, 2000)The survival of milkfish broodstock (body weight range 1–11 kg) was determined until 30 days after handling and transport in open tanks or in sealed oxygenated bags containing chilled sea water (20–25 °C). Maintenance of ... -
GABA enhances reproduction of the rotifer Brachionus plicatilis Muller: application to mass culture
(Wiley-Blackwell, 2000)Based on the results of individual and batch culture experiments in small volumes, we conducted experiments in larger volumes of 100 mL, 1 L and 10 L to determine: (1) at what phase of population growth would gamma-aminobutyric ... -
Effect of juvenile hormone and serotonin (5-HT) on mixis induction of the rotifer Brachionus plicatilis Muller
(Elsevier, 2000)Juvenile hormone (JH) and serotonin (5-HT) were previously shown to enhance mictic (sexual) female production of the rotifer Brachionus plicatilis in batch cultures. To explore the basis of these effects, experiments were ... -
GABA, 5-HT and amino acids in the rotifers Brachionus plicatilis and Brachionus rotundiformis
(Elsevier, 2000)γ-Aminobutyric acid (GABA) and 5-hydroxytryptamine (5-HT) have been shown to increase the reproduction of the Brachionus plicatilis (NH3L strain). In the present study, the endogenous presence of GABA and 5-HT in the ... -
Feeding, growth and survival of abalone (Haliotis asinina Linnaeus 1758) reared at different stocking densities in suspended mesh cages in flow-through tanks
(San Carlos Publications, University of San Carlos, 2000)Feeding, growth and survival of hatchery-bred juvenile abalone, Haliotis asinina (mean initial shell lengths: 32 mm) stocked at 25, 50 and 100 m-2 of shelter surface area in mesh cages suspended in indoor ... -
Nutritional evaluation of various plant protein sources in diets for Asian sea bass Lates calcarifer
(Wiley-Blackwell, 2000)A biological assay was conducted to evaluate the suitability of various leguminous seed meals and leaf meals as dietary protein sources for Asian sea bass, Lates calcarifer. In the growth experiment, fish (initial mean ... -
Salinity tolerance of larvae of the mangrove red snapper (Lutjanus argentimaculatus) during ontogeny
(Elsevier, 2000)Salinity tolerance and the effects of salinity on growth, condition factor and chloride cell (CC) densities were evaluated for Lutjanus argentimaculatus larvae during ontogeny. Tolerance of L. argentimaculatus larvae to ... -

Growth and survival of river catfish Mystus nemurus (Cuvier & Valenciennes) larvae fed isocaloric diets with different protein levels during weaning
(Blackwell Publishing, 2000)The growth of river catfish Mystus nemurus (Cuvier & Valenciennes) larvae fed four isocaloric diets (4200 kcal kg−1) with different protein levels during weaning was determined. Diets containing 45, 50, 55, ... -
