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 ...
Light color and ovarian maturation in unablated and ablated giant tiger prawn Penaeus monodon (Fabricius)
(Elsevier, 1992)
The effect of light color (green, blue and white fluorescent lights, with natural light as a control) on maturation in intact and eyestalk-ablated Penaeus monodon was tested in 12-m<sup>3</sup> broodstock tanks. Size and ...
Utilization of feed pea, Pisum sativum, meal as protein source in practical diets for juvenile shrimp, Penaeus monodon
(Elsevier, 2003)
The potential of feed pea meal as an alternative protein source to soybean meal in practical diets for the juvenile tiger shrimp, Penaeus monodon, was assessed in several experiments. Six isonitrogenous diets were formulated ...
Presence of snapper, seabass, and siganid inhibits growth of luminous bacteria in a simulated shrimp culture system
(Elsevier, 2006)
The antibacterial effect of the presence of Tilapia hornorum against luminous bacteria in shrimp culture has been reported. This study investigates how the presence of commercially valued marine species such as seabass, ...
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 ...
Variation in the biochemical composition of Penaeus monodon tissues during the reproductive cycle.
(Bamidgeh, 1990)
The gonadosomatic index (GSI) and the hepatosomatic index (HSI) were determined for wild-caught, eyestalk ablated Penaeus monodon at 5 reproductive stages (I to V). Tissues of the muscle, ovary and hepatopancreas in each ...
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 ...
Survival rates of different Penaeus monodon Fabricius postlarval stages
(National Science Development Board, 1976)
Four different postlarval stages (P<sub>11</sub>, P<sub>15</sub> , P<sub>21</sub>, and P<sub>25</sub>) of P. monodon were stocked in suspension nets at the rate of 200 fry/sq m with 3 nets for each postlarval stage. Pond ...
A simple method of tagging prawns
(University of the Philippines, 1976)
The recognition of individual animals is crucial to many aspects of research. Prawns present unique difficulties in this respect since they molt regularly. Thus almost all tagging and marking methods developed for prawns ...
