Effects of unilateral eyestalk ablation on ovarian histology and oocyte size frequency of wild and pond-reared Penaeus monodon (Fabricius) broodstock
(Elsevier, 1991)
Effects of eyestalk ablation on ovarian maturation of wild and pond-reared Penaeus monodon were determined to compare their reproductive potential. This was done by counting the oocyte size frequency in four regions of the ...
Profiles of progesterone- and estradiol-like substances in the hemolymph of female Pandalus kessleri during an annual reproductive cycle
(Elsevier, 1991)
The changes in GSI and HSI of Pandalus kessleri were monitored during an annual reproductive cycle. GSI reached a peak when ovaries were composed of yolky oocytes and decreased sharply during the spawning season. HSI ...
Effects of Gusathion A on the survival and shell quality of juvenile Penaeus monodon
(Elsevier, 1991)
Juvenile Penaeus monodon (body weight=10–20 g) were exposed to a commonly used organophosphate pesticide, Gusathion A, in ponds for 96 h. Prawns exposed to 1.5–150 ppb Gusathion A had 27–53% shell softening, with a 96 h ...
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 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 ...
Accumulation and tissue distribution of radioiodine (131I) from algal phytoplankton by the freshwater clam Corbicula manilensis
(Springer Verlag, 1991)
Radioactive wastes discharged from establishments involved in the use of radioisotopes such as nuclear powered industries, tracer research and nuclear medicine are a potential public health hazard. Such wastes contain ...
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 ...
Yield of Penaeus monodon Fabricius in brackishwater ponds given different fertilizer combinations
(Elsevier, 1991)
Yields of Penaeus monodon Fabricius in brackishwater earthen ponds were determined using different fertilizer combinations in two sets of experiments. Results indicated that the use of fertilizers was vitally needed to ...
Growth and fatty acid composition of Penaeus monodon juveniles fed various lipids
(Society of Israeli Aquaculture and Marine Biotechnology, 1991)
A 4-week feeding trial was conducted to determine the growth and fatty acid composition of Penaeus monodon juveniles fed dietary lipids from different sources. The animal lipid (cod liver oil, pork lard and beef tallow) ...
Selective diversification of aquaculture stocks: A proposal for economically sustainable genetic conservation
(NRC Research Press, 1991)
The genetic diversity of aquaculture stocks can be maintained, and their genetic impact on wild stocks minimized, by breeding programmes that deliberately generate genetic diversity. Current animal breeding practices are ...
