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, ... -
Marine leech (Zeylanicobdella arugamensis) infestation in cultured orange-spotted grouper, Epinephelus coioides
(Elsevier, 2000)Heavy infestation of a marine leech occurred among tank-reared juvenile and adult orange-spotted grouper, Epinephelus coioides Hamilton, at SEAFDEC AQD, Philippines with a prevalence of 83% and 17%, respectively. The leeches ... -
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)
