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 ...
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 ...
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 ...
Experimental infection of kuruma prawn (Penaeus japonicus) with Vibrio penaeicida
(The Society of Israeli Aquaculture and Marine Biotechnology, 1998)
To estimate the portal of entry of Vibrio penaeicida in kuruma prawn (Penaeus japonicus), immersion and oral infection experiments were conducted with pre-treated and intact prawns. In immersion challenge, V. penaeicida ...
Effects of antioxidants on feed quality and growth of Penaeus monodon juveniles
(Wiley-Blackwell, 1992)
Four practical diets were formulated to contain 0.05%, of the following antioxidants: butylated hydroxytoluene (BHT), butylated hydroxy anisole (BHA), propyl gallate (PG) or ethoxyquin (ETHQ). A fifth diet, with no added ...
