Larval rearing of the Philippine freshwater catfish, Clarias macrocephalus (Gunther), fed live zooplankton and artificial diet: A preliminary study
(Society of Israeli Aquaculture and Marine Biotechnology, 1991)
A preliminary study was conducted to determine growth and survival of Clarias macrocephalus fed live zooplankton (Artemia or Moina macrocopa ) and/or a dry artificial diet. The specific growth rate over a 14-day rearing ...
Harvesting Gracilariopsis heteroclada (Gracilariales, Rhodophyta) in Iloilo, Philippines
(Science and Technology Information Institute, 1993)
Gracilariopsis heteroclada thalli were planted in a 1 m2 ditch along a drainage canal at Leganes, Iloilo, Philippines. Monthly growth rate and production were calculated to determine the effect of harvesting on the ...
Thyroid hormone surges during milkfish metamorphosis
(Society of Israeli Aquaculture and Marine Biotechnology, 1994)
Both thyroxine (T<sub>4</sub>) and triiodothyronine (T<sub>3</sub>) were detected in fertilized eggs and larvae of milkfish. The concentration of T<sub>4</sub> was lower than that of T<sub>3</sub> only in fertilized eggs ...
The essential fatty acid requirement of milkfish (Chanos chanos Forsskal)
(Springer Verlag, 1992)
The essential fatty acid (EFA) requirement of milkfish was examined by a 12-week feeding trial using defined, purified diets at water temperature of 28–29°C and salinity of 32‰. The test diets contained varying levels of ...
Acceptability of territorial use rights in fisheries: towards community-based management of small-scale fisheries in the Philippines
(Elsevier, 1992)
The granting of territorial use rights in fisheries (TURFs) to fisherfolk associations, similar to that practiced in Japan, is recommended as a management tool for small-scale fisheries in the Philippines. This study, ...
Spermiation response of mature rabbitfish, Siganus guttatus Bloch, to luteinizing hormone-releasing hormone analogue (LHRHa) injection
(Elsevier, 1991)
A method to quantify the spermiation response of mature rabbitfish to hormonal therapy is described. Spermatocrit or packed sperm volume was measured after milt loaded in non-heparinized microhematocrit capillary tubes was ...
Agar production from Gracilariopsis heteroclada (Gracilariales, Rhodophyta) grown at different salinity levels
(Walter de Gruyter, 1994)
Gracilariopsis heteroclada grown in fiber glass tanks at four salinity levels was treated with three different concentrations of aqueous NaOH. Yield, gel strength, gelling and melting temperatures of the extracted agar ...
Virulence and production of extracellular proteins (ECP) of Aeromonas hydrophila associated with the epizootic ulcerative syndrome (EUS) of freshwater fish
(University of the Philippines in the Visayas, 1996)
Sixteen isolates of Aeromonas hydrophila isolated from normal, apparently normal and epizootic-ulcerative syndrome (EUS)-affected fish were screened for virulence and production of extracellular proteins (ECP). Results ...
Tissue lipid content and fatty acid composition during ovarian maturation of ablated Penaeus monodon
(Society of Israeli Aquaculture and Marine Biotechnology, 1993)
The total lipid content and fatty acid composition in the hepatopancreas, muscle and gonad of ablated Penaeus monodon females at ovarian maturation Stages I to V were examined. The lipid content was highest in the ...
Agar yield, gel strength and sulfate content in Gracilariopsis heteroclada farmed in brackishwater canals
(Society of Israeli Aquaculture and Marine Biotechnology, 1996)
This paper aimed at determining the optimum NaOH pretreatment strength and duration and the monthly variations in gel strength, agar yield and sulfate content of agar from Gracilariopsis heteroclada (Zhang et Xia) farmed ...
