Salinity tolerance of fertilized eggs and yolk-sac larvae of the rabbitfish Siganus guttatus (Bloch)
(Elsevier, 1993)
Among naturally spawned and hormonally induced eggs of Siganus guttatus, salinity levels, at which at least 90% of the eggs hatched, ranged from 7 to 67 ppt for naturally spawned eggs and from 9 to 67 ppt for hormonally ...
Larval rearing of the grouper Epinephelus suillus under laboratory conditions
(Elsevier, 1997)
A protocol for rearing orange-spotted rockcod, Epinephelus suillus in the hatchery is described. The feeding regime consisted of Chlorella, Brachionus, Artemia and minced fish. With this regime, survival rates at Day 24 ...
The effects on growth and survival of feeding water fleas (Moina macrocopa Straus) and rotifers (Brachionus plicatilis ) to milkfish (Chanos chanos Forsskal) fry
(Society of Israeli Aquaculture and Marine Biotechnology, 1990)
The effects of feeding water fleas, Moina macrocopa Straus, and rotifers, Brachionus plicatilis, to milkfish, Chanos chanos Forsskal, fry at different feeding rates and frequencies were investigated. Fry (4.66 mg average ...
Effect of streamer tags on survival and growth of juvenile tiger prawns, Penaeus monodon, under laboratory conditions
(CSIRO Publishing, 1992)
The effects of streamer tags and initial prawn size on survival and growth in 2-month- and 7-month-old pond-reared juveniles of Penaeus monodon Fabricius (11-30 mm carapace length, CL) were assessed under laboratory ...
Survival and metamorphosis of Penaeus monodon larvae at different salinity levels
(Society of Israeli Aquaculture and Marine Biotechnology, 1993)
The survival rates of Penaeus monodon nauplii, protozoea and mysis abruptly exposed to salinity of 12, 16, 20, 24, 28, 36, 40 and 50 ppt were determined and compared. Larvae kept at 32 ppt, the spawning or initial rearing ...
Commercial evaluation of monosex pond culture of the mud crab Scylla species at three stocking densities in the Philippines.
(Elsevier, 1999)
The effects of three levels of stocking density (0.5, 1.5 or 3.0 m<sup>−2</sup>) and monosex culture (male or female) on the growth, apparent feed conversion ratio (FCR), survival, and production of mixed species of mud ...
Interaction between dietary levels of calcium and phosphorus on growth of juvenile shrimp, Penaeus monodon
(Elsevier, 1999)
Information on the dietary phosphorus (P) requirement is essential in the formulation of a cost-effective and low-pollutant feed. Ten isonitrogenous (40% CP) casein–gelatin-based diets containing five graded levels of P ...
Survival of Penaeus monodon postlarvae and juveniles at different salinity and temperature levels.
(Society of Israeli Aquaculture and Marine Biotechnology, 1998)
Penaeus monodon postlarvae (PL1, PL5, PL10, and PL15) and juveniles (0.2 and 2 g mean weights) were acclimated gradually within 6 h to test temperatures of 22°, 28°, and 33°C. After 24 h, the postlarvae were abruptly ...
Evaluation of different supplemental feeds for milkfish (Chanos chanos) reared in brackishwater ponds
(Elsevier, 1991)
The effects of supplemental feeding on milkfish growth, production, survival, water quality, and economic benefits in brackishwater ponds were evaluated by comparing a rice bran diet, containing 11.3% protein, and two ...
Effect of rotenone and saponin on the shell quality of juvenile tiger shrimp, Penaeus monodon
(Society of Israeli Aquaculture and Marine Biotechnology, 1993)
Tiger shrimp (Penaeus monodon) juveniles were exposed to varying concentrations of rotenone and saponin to determine their effects on survival and shell quality. The highest concentrations tested, 50 ppm rotenone and 100 ...
