Early larval development of the seabass Lates calcarifer with emphasis on the transition of energy sources
(Japanese Society of Fisheries Science, 1986)
The early growth, yolk and oil globule resorption, early morphological and behavioral de-velopment, and initial feeding of hatchery-raised Lates calcarifer were studied. Based on the developmental events and the energy the ...
Effects of exogenous hormone injections on milt consistency in newly caught, wild milkfish
(University of the Philippines at Los Baños, 1980)
The study was conducted to study the effects of single injections of Human Chorionic Gonadotropin (HCG) (Ayerst Laboratories, Inc) and Durandron Forte 250, a long-acting androgen preparation (N.V. Organon Oss, Holland), ...
Milkfish fry and fingerling resources of Sri Lanka
(Ministry of Fisheries and Aquatic Resources, 1982)
Sri Lanka has the milkfish (Chanos chanos) seed and water resources for the development of milkfish aquaculture as a new industry. Milkfish fry and fingerlings are present in all surveyed coastal wet lands, but are abundant ...
Midgut gland as monitor organ for the nutritional value of diets in Penaeus monodon (Decapoda)
(Elsevier, 1985)
Midgut gland cells of Penaeus monodon postlarvae were investigated by electron microscopy after starvation and refeeding with different diets.
Well nourished postlarvae could be starved for 5 days without irreversible ...
An inexpensive tag for short-term studies in milkfish (Chanos chanos Forsskal) and in seabass (Lates calcarifer Bloch)
(Blackwell Publishing, 1988)
An opercular tag for marking adult milkfish (Chanos chanos Forsskal) and seabass (Lates calcarifer Bloch) is described. High tag retention and relatively low mortality rates were observed in adult fish handled two to ten ...
A fundamental study on the behavior of milkfish fry for improving the efficiency of traditional fry collecting gear in the Philippines
(Kagoshima University Research Center for the South Pacific, 1980)
The reaction of milkfish fry to miving and stationary nets of different meshes and colors in an experimental tank was determined. The underwater visibility of the nets saw measured and the water filtration in a fry-sweeper ...
Larval and postlarval development of the window pane shell, Placuna placenta Linnaeus, (Bivalvia: Placunidae) with a discussion on its natural settlement.
(California Malacozoological Society, Inc., 1980)
Stages of development of P. placenta from the straight-hinge veliger to the adult are described. Mature larvae metamorphose at lengths from 220-230 m. Larvae probably attach byssally to the water surface at metamorphosis ...
Ovarian maturation stages of the wild giant tiger prawn, Penaeus monodon Fabricius
(Elsevier, 1989)
A qualitative and quantitative study of the ovarian maturation stages of wild-caught Penaeus monodon was conducted to refine the existing method of staging. For industrial purpose, measuring the ovarian width at the first ...
Growth and survival of bighead carp (Aristichthys nobilis) fry fed at different intake levels and feeding frequencies
(Elsevier, 1988)
This study was conducted to assess the effect of different levels of dietary intake and feeding frequencies on growth and survival of bigheadcarp, Aristichthys nobilis, fry. The feeding rates consisted of 10%, 20%, and 30% ...
Hatchery production of Oreochromis niloticus L. at different sex ratios and stocking densities
(Elsevier, 1988)
The influence of various sex ratios and stocking densities on hatchery production of Nile tilapia, Oreochromis niloticus L., was studied in land-based (concrete tanks) and lake-based (hapa nets) systems. In both hatchery ...
