Food preference of wild milkfish juveniles in connection with habitat and food availability
(Taylor & Francis, 1989)
Through quantitative determination of the gut content of wild milk fish (Chanos chanos) juveniles, the study aimed to evaluate the food preference of the fish in relation to its availability in the pond so that necessary ...
The effects of Vibrio anguillarum extracellular products on Japanese eels
(Elsevier, 1989)
To test the effect of Vibrio anguillarum extracellular products (ECP) on Japanese eels (Anguilla japonica ), test fish were injected intramuscularly with ECP at a dose of 1 mg protein/100 g body weight of fish.At 3,6,12,24 ...
Ion chromatography of inorganic anions in brine samples
(Oxford University Press, 1989)
An ion chromatographic method for separating and detecting anions in brine samples is described. Nitrite, bromide, nitrate, and sulfate ions in brine samples are well separated when chloride ion concentration in the sample ...
Identification and characterization of vitellin in a hermaphrodite shrimp, Pandalus kessleri
(Elsevier, 1989)
1. A female specific protein (FSP, vitellogenin) in hemolymph and its related ovarian protein (vitellin) of Pandalus kessleri were studied by means of electrophoretical and immunological procedures.
2. The vitellin was ...
Dose-dependent spawning response of mature female sea bass, Lates calcarifer (Bloch), to pelleted luteinizing hormone-releasing hormone analogue (LHRHa)
(Elsevier, 1989)
The induction of sequential spawnings of mature female sea bass following intraperitoneal implantation of various doses of luteinizing hormone-releasing hormone analogue (LHRHa) in a 95% cholesterol pellet was investigated. ...
Ingestion saturation and growth responses of Penaeus monodon larvae to food density
(Elsevier, 1989)
Different larval stages of Penaeus monodon were fed with increasing densities of Tetraselmis sp. to evaluate the relationship between food density, ingestion rates, development and growth of Penaeus monodon larvae. Ingestion ...
Effect of salinity on hemolymph calcium concentration during the molt cycle of the prawn Penaeus monodon
(Springer Verlag, 1989)
Prawns (Penaeus monodon) were obtained from ponds in Iloilo, Philippines, in 1984 and 1985 and maintained in salinities from 8 to 44‰. Total hemolymph calcium was largely affected by molt stage and less so by salinity. A ...
Development of an ovarian biopsy technique in the sea bass, Lates calcarifer (Bloch).
(Elsevier, 1989)
A convenient and rapid biopsy method for taking ovarian samples from mature sea bass (Lates calcarifer Bloch) is described. Intra-ovarian oocytes siphoned with polyethylene tubing from any region of the ovary provide a ...
Ovarian development and changes in the serum vitellogenin levels in the river sculpin, Cottus hangiongensis, during an annual reproductive cycle
(Faculty of Fisheries, Hokkaido University, 1989)
Annual changes in the ovarian development and serum vitellogenin concentration were investigated in the river sculpin, Cottus hangiongensis, sampled monthly from a river in southern Hokkaido, Japan. Ovarian development ...
An evaluation of indigenous protein sources as potential component in the diet formulation for tiger prawn, Penaeus monodon, using essential amino acid index (EAAI)
(Elsevier, 1989)
The essential amino acid index (EAAI) could be used in screening potential protein sources. However, when formulating diets, EAAI should be supported with feeding trials and digestibility tests to determine the extent of ...
