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 ...
Ovarian maturation stages of the wild giant tiger prawn, Penaeus monodon Fabricius
(Elsevier, 1989)
A qualitative and quantitative study of the ovarian maturation stages of wild-caught Penaeus monodon was conducted to refine the existing method of staging. For industrial purpose, measuring the ovarian width at the first ...
Evaluation of milkfish (Chanos chanos Forskal) and prawn (Penaeus monodon Fabricus) in polyculture system
(Fisheries Research Society of the Philippines, 1982)
The growth, survival and profitability of milkfish (C. chanos ) and prawn (Penaeus monodon ) (averaging 3.1 g and 0.3 g, respectively) grown in five different combinations for 100 days in 500-m super(2) brackishwater ponds ...
Survival, growth and production of Penaeus monodon Fabricius at different stocking densities in earthen ponds with flow-through system and supplemental feeding.
(Fisheries Research Society of the Philippines, 1981)
Penaeus monodon juveniles (P<sub>53</sub>-P<sub>54</sub>, 0.45 g) were stocked in 200 m<sup>2</sup> earthen ponds with water exchange rate of 5-10% daily, and reared for 3.5 months. Stocking density levels of 2.5, 5.0, 10 ...
Effect of tagging on maturation and survival of ablated Penaeus monodon in painted and unpainted tanks
(San Carlos Publications, University of San Carlos, 1989)
A study was conducted to determine the effects of tags and tank color on reproductive performance and survival of pond-reared Penaeus monodon after eyestalk ablation. In 1986, the best over-all reproductive performance was ...
Supplement of various attractants to a practical diet for juvenile Penaeus monodon Fabricius
(Fisheries Research Society of the Philippines, 1983)
Practical diets supplemented with krill meal (5%), earthworm meal (5%), glycine (2%), sucrose (5%) or mussel extract as an attractant were fed for eight weeks to juvenile Penaeus monodon. The major protein sources of the ...
Use of kappa-carrageenan microbound diet (C-MBD) as feed for Penaeus monodon larvae
(Springer Verlag, 1989)
The performance of an artificial practical diet, kappa-carrageenan microbound diet (C-MBD) was assessed on Penaeus monodon larvae at the SEAFDEC Broodstock and Maturation Experimental Laboratory in March 1986. Shrimps were ...
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 ...
