Heterogeneity in Philippine milkfish populations
(Asian Fisheries Society, 1990)
Twelve milkfish (Chanos chanos ) populations from 6 coastal areas in the Philippines, collected at the fry stage and reared until fingerling size, were analysed for electrophoretic variation at 28 presumptive loci. Seven ...
Survival of young rabbitfish (Siganus guttatus Bloch) under simulated transport conditions
(Blackwell Publishing, 1990)
The effect of loading density, transport duration, water temperature, and salinity on survival of young rabbitfish (Siganus guttatus Bloch) under simulated transport conditions was investigated. The rocking motion of ...
Variation in the biochemical composition of Penaeus monodon tissues during the reproductive cycle.
(Bamidgeh, 1990)
The gonadosomatic index (GSI) and the hepatosomatic index (HSI) were determined for wild-caught, eyestalk ablated Penaeus monodon at 5 reproductive stages (I to V). Tissues of the muscle, ovary and hepatopancreas in each ...
Chlorination of seawater used for shrimp culture
(SIAMB, 1990)
Chlorination of sand-filtered and microfiltered seawater for 24 hours significantly reduced the initial bacterial load from 10<sup>5</sup> to 10<sup>0</sup> - 10<sup>1</sup> colony forming units (cfu) per ml. The total ...
Advancement of sexual maturation and spawning of sea bass, Lates calcarifer (Bloch), using pelleted luteinizing hormone-releasing hormone analogue and 17α-methyltestosterone.
(Elsevier, 1990)
The ability of luteinizing hormone-releasing hormone analogue [(D-Ala<sup>6</sup>, Pro<sup>9</sup>-NEt)LHRH], 17α-methyltestosterone (MT), and their combination to advance gonadal maturation and spawning in captive sea ...
Supplemental feeding of Penaeus monodon juveniles with diets containing various levels of defatted soybean meal
(Elsevier, 1990)
Varying levels of defattedsoybeanmeal DSM (15, 25, 35, 45 and 55%) in supplementaldiets with approximately 40% crude protein and 10% crude fat were fed to tiger prawn juveniles in 1 m×1 m×1 m net cages set on the bottom ...
Studies on the chemical control of luminous bacteria Vibrio harveyi and V. splendidus isolated from diseased Penaeus monodon larvae and rearing water
(Inter Research, 1990)
The minimum inhibitory concentrations (MICs) and minimum bactericidal concentrations (MBCs) of 24 drugs for luminous bacteria Vibrio harveyi and V. splendidus were determined. Only chloramphenicol, sodium nifurstyrenate ...
Isolation and characterization of vitellin from the ovary of Penaeus monodon
(International Society of Invertebrate Reproduction and Development, 1990)
Female-specific protein (FSP, vitellogenin) in Penaeus monodon hemolymph and its related ovarian protein (vitellin, lipovitellin) were identified and characterized using electrophoretical and immunological procedures. The ...
Tissue distribution of mercury and selenium in minnows, Phoxinus phoxinus
(Springer Verlag, 1990)
The protective effect of selenium against mercury toxicity has been extensively demonstrated in a number of studies (Burke eta]. 1977; Kasuya 1976). Since mercury uptake is not always diminished by the presence of selenium ...
Organic pollution resulting from excess feed and metabolite build-up: Effect on Penaeus monodon postlarvae
(Elsevier, 1990)
Penaeus monodon postlarvae, PL, with mean weight and mean total length of 0.57 mg and 6.5 mm respectively, were stocked in aerated aquaria at 20 litre<sup>−1</sup> of seawater. They were fed minced shrimp meat at rates of ...
