Effects of different sex ratios on maturation, fecundity and hatching rates of ablated Penaeus monodon wild stock
(Fisheries Research Society of the Philippines, 1980)
The minimum number of males per female that would still ensure high maturation, fecundity and hatching rates in Penaeus monodon broodstock, is determined. Wild stock P. monodon were stocked in 4 m diameter circular tanks ...
Histopathology of the chronic soft-shell syndrome in the tiger prawn Penaeus monodon
(Inter Research, 1987)
One of the disease problems that affect the production of tiger prawn Penaeus monodon Fabricius in brackish-water ponds is the chronic soft-shell syndrome, a condition in which the prawn shell is persistently soft for ...
An assessment of algal growth in net cages in Laguna Lake
(Fisheries Research Society of the Philippines, 1981)
Quantitative determination of the algal population, in terms of cells/ml and biomass/ml, was conducted during the first month of growing P. monodon postlarvae in Laguna Lake. Algae were sampled from each side of net cages ...
Studies on the chronic soft-shell syndrome in the tiger prawn, Penaeus monodon Fabricius, from brackishwater ponds
(Elsevier, 1986)
Prawn culture is becoming more widespread in the Philippines. In recent years, prawn production in brackishwater ponds has been adversely affected by a chronic soft-shell syndrome. A field survey of prawn ponds in the ...
Midgut gland as monitor organ for the nutritional value of diets in Penaeus monodon (Decapoda)
(Elsevier, 1985)
Midgut gland cells of Penaeus monodon postlarvae were investigated by electron microscopy after starvation and refeeding with different diets.
Well nourished postlarvae could be starved for 5 days without irreversible ...
Feeding behavior and food preference of Penaeus monodon Fabricius with scrap Tilapia mossambica
(Fisheries Research Society of the Philippines, 1981)
The time of day during which P. monodon feeds at different depth levels in earthen ponds, and its preference for three types of tilapia feeds (dry, fresh and fermented) were determined. It was observed that P. monodon ...
Acclimation of Penaeus monodon postlarvae to fresh water
(Fisheries Research Society of the Philippines, 1980)
Gradual acclimation of Penaeus monodon Fabricius to fresh water was conducted in glass aquaria and marine plywood tanks over a one-day, two-day, and three-day acclimation periods. Different stages of postlarvae were ...
The response of Penaeus monodon juveniles to varying protein/energy ratios in test diets
(Elsevier, 1986)
Two sets of factorial experiments were conducted for 8 weeks to determine the response of Penaeus monodon juveniles (average weights = 0.60 ± 0.16 g and 0.80 ± 0.05 g) to diets containing various protein/energy ratios. The ...
