Increasing milkfish (Chanos chanos) yields in brackishwater ponds through increased stocking rates and supplementary feeding
(Asian Fisheries Society, 1990)
Brackishwater milkfish culture in the Philippines is normally practiced at fish stocking rates of 2,000-3,000 ha<sup>-1</sup> with fertilizers as the sole nutrient input. Supplementary feeding is not common. We stocked two ...
Daily amount of rotifers taken by a sea bass Lates calcarifer larvae
(Science and Technology Information Institute, 1990)
The amount of rotifers consumed by a single sea bass Lates calcarifer larva per day (R) was examined by both the direct and by the satiation-digestion methods. In the direct method, R is estimated by the number of rotifers ...
Improved larval survival at metamorphosis of Asian seabass (Lates calcarifer) using ω3-HUFA-enriched live food
(Elsevier, 1990)
Asian seabass (Lates calcarifer) larvae were fed Brachionus cultured on Chlorella and, as soon as ingestin was possible, different types of Artemia, i.e., nauplii of the San Francisco Bay (SFB) strain, Great Salt Lake (GSL) ...
Studies on the digestive lipases of milkfish, Chanos chanos
(Elsevier, 1990)
Milkfish grown on two natural foods were examined to determine the distribution pattern of the digestive lipases along the digestive tract and to identify the optimum condition for lipase activity. One food consisted of a ...
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 ...
