The in vitro effects of cyclic nucleotides, cyanoketone, and cycloheximide on the production of estradiol-17β by vitellogenic ovarian follicles of goldfish (Carassius auratus)
(Academic Press, 1986)
The effects of human chorionic gonadotropin (HCG), forskolin, cyclic nucleotides, the phosphodiesterase inhibitors IBMX and theophylline, cyanoketone, and cycloheximide on the production of estradiol-17β by isolated ovarian ...
Duration of feeding and indirect selection for growth of tilapia
(Elsevier, 1986)
Duration of spontaneous feeding was observed at three times each day in a laboratory population of nine juvenile tilapia (Oreochromis mossambicus). Growth of the fish was measured as change in length and weight, and also ...
Early development of fin-supports and fin-rays in the milkfish Chanos chanos
(The Ichthyological Society of Japan, 1986)
Development of fin-supports and fin-rays was observed in larval and juvenileChanos chanos, Chondrification of the caudal complex started at 4.70 mm SL. Ossification of the caudal elements started at 7.80 mm SL and was ...
Harvesting techniques for Nile tilapia fingerlings
(Fisheries Research Society of the Philippines, 1986)
The experiment was conducted in nine-320m<sup>2</sup> - freshwater ponds to evaluate various techniques of harvesting tilapia fry. Three treatments with three replicates each were used: harvesting by seining the fry ...
Early development of Crassostrea iredalei (Faustino, 1932) (Bivalvia: Ostreidae), with notes on the structure of the larval hinge
(California Malacozoological Society, Inc., 1986)
Larvae of the oyster Crassostrea iredalei were reared in the laboratory from eggs through settlement. The oysters were induced to spawn by increasing the temperature by 5-10°C and sometimes by adding stripped oyster sperm ...
Studies on the chronic soft-shell syndrome in the tiger prawn, Penaeus monodon Fabricius, from brackishwater ponds
(Elsevier, 1986)
Prawn culture is becoming more widespread in the Philippines. In recent years, prawn production in brackishwater ponds has been adversely affected by a chronic soft-shell syndrome. A field survey of prawn ponds in the ...
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 ...
Induced maturation and spawning of milkfish, Chanos chanos Forsskal, by hormone implantation
(Elsevier, 1986)
The milkfish, Chanos chanos Forsskal, does not reach gonadal maturity easily in captivity. In an attempt to induce maturation, exogenous hormones, LHRH-A and 17α-methyl-testosterone, were implanted into adult milkfish ...
Digestibility in milkfish, Chanos chanos (Forsskal): Effects of protein source, fish size and salinity
(Elsevier, 1986)
The true digestibility of casein, gelatin, fish meal, defatted soybean meal and Leucaena leucocephala leaf meal was measured in 60- and 175-g milkfish (Chanos chanos Forsskal) in fresh- and seawater. The diets contained ...
Effect of salinity on the osmotic, chloride, total protein and calcium concentrations in the hemolymph of the prawn Peneaus monodon (Fabricius)
(Elsevier, 1986)
1. Osmolality and chloride concentrations in the hemolymph of Penaeus monodon became stable 1 day after molting in 32 ppt, while total protein and calcium concentrations remained stable throughout the molting cycle. When ...
