Fishing methods and gears in Panay Island, Philippines
(Faculty of Fisheries, Kagoshima University, 1980)The authors surveyed the fishing methods and gears in Panay and smaller neighboring islands in the Philippines in September-December 1979 and in March-May 1980. This paper is a report on the fishing methods and gears used ... -
Effects of different sex ratios on maturation, fecundity and hatching rates of ablated Penaeus monodon wild stock
(Fisheries Research Society of the Philippines, 1980)The minimum number of males per female that would still ensure high maturation, fecundity and hatching rates in Penaeus monodon broodstock, is determined. Wild stock P. monodon were stocked in 4 m diameter circular tanks ... -
Effect of various salinity levels and stock manipulation methods on the survival of milkfish fry (Chanos chanos) during storage.
(Fisheries Research Society of the Philippines, 1980)The survival and growth of milkfish (Chanos chanos ) fry stored in plastic basins at different salinity levels and stock manipulation methods without aeration and fed with hard-boiled chicken egg yolk over a period of 14 ... -
Effect of substrate types on fecundity and nauplii production of ablated Penaeus monodon Fabricius
(Science and Technology Information Institute, Department of Science and Technology, 1980)The survival, spawning, fecundity, and nauplii production of ablated Penaeus monodon females reared in flow-through broodstock tanks with white coralline and black sand substrates for 62 days, were assessed. Prawns exposed ... -
Ecology on the feeding of milkfish fry and juveniles, Chanos chanos (Forsskal) in the Philippines
(Kagoshima University Research Center for the South Pacific, 1980)An extensive ecological survey was conducted in the Philippines to study the feeding of milkfish, Chanos chanos Forsskal. Types of environments examined included coral reefs, lagoons, mangrove and nipa swamps as well as ... -
Early postmysis stages of the giant tiger prawn, Penaeus monodon Fabricius
(Carcinological Society of Japan, 1980)The morphological development of the early postmysis stages of the giant tiger prawn, Penaeus monodon are described and illustrated using laboratory-reared specimens and wild ones. The first 3 or 4 substages are termed ... -
Culture experiments on the harpacticoid copepod, Tisbintra elongata Mori, and evaluation of that species as a food organism for milkfish larvae
(Faculty of Fisheries, Kagoshima University, 1980)The mass culture of the harpacticoid copepod, Tisbintra elongata, indigenous to Panay Island were conducted, feeding them on several kinds of food materials. Salinity tolerance as physiological parameter was also examined. ... -
