Effect of dietary astaxanthin and vitamin A on the reproductive performance of Penaeus monodon broodstock
(Cambridge University Press, 1998)
The reproductive performance of pond tiger shrimp given astaxanthin (100 mg·kg<sup>−1</sup>) and/or vitamin A (20 000 IU·kg<sup>−1</sup>) for 61 d in tanks was assessed in a 2 × 2 factorial experiment in a completely ...
Bacterial diseases in shrimp (Penaeus monodon) culture in the Philippines
(Japanese Society of Fish Pathology, 1998)
The hatchery system for Penaeus monodon evolved from the Japanese community culture system to the modified Galveston method and this shift in culture technique triggered the outbreak of diseases due to opportunistic bacteria. ...
L-ascorbyl-2-phosphate Mg as source of vitamin C for juvenile Penaeus monodon
(Society of Israeli Aquaculture and Marine Biotechnology, 1994)
Phosphated ascorbic acid (MAP), a stable vitamin C derivative, was used in practical diets for Penaeus monodon (wet weight, 126-254 mg) as a source of vitamin C. In Experiment I, the levels were from 0 to 1,500 ppm MAP. ...
Effects of unilateral eyestalk ablation on growth and reproductive parameters in wild and pond-reared Penaeus monodon (Fabricius) broodstock
(San Carlos Publications, University of San Carlos, 1991)
Effects of unilateral eyestalk ablation on wild and pond-reared Penaeus monodon during ovarian maturation were determined by examining the growth (e.g., carapace length, body length, body weight) and reproductive (e.g., ...
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 ...
Effect of dehulling on the nutritive value of some leguminous seeds as protein sources for tiger prawn, Penaeus monodon, juveniles
(Elsevier, 1991)
Feeding experiments were conducted to evaluate the effect of dehulling on the nutritive value of cowpea and rice bean as protein sources for P. monodon juveniles. Diets were prepared by adding legumes to replace 15.6% of ...
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 ...
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 ...
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 ...
