Staggered harvesting as a method of increasing prawn production with supplemental feeding
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Prawns, like any other animals, exhibit dissimilarities in growth rates. As they grow, a wide range of body weight distribution from the same population is observed. Staggered harvesting method is commonly practised in ...
Ruppia maritima and Najas graminea as natural foods for Penaeus monodon juveniles
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Ruppia maritima (kusay-kusay, Hiligaynon) and Najas graminea (digman, Hiligaynon) are macrophytes growing in local brackishwater ponds believed to provide food and shelter to prawns and fishes. Their effect on growth and ...
Effects of diet on reproductive performance of ablated Penaeus monodon broodstock
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Four practical diets were compared for their effects upon ovarian maturation and spawning of ablated Penaeus monodon broodstock. Diets were formulated based upon the fatty acid profile of wild P. monodon. Diets 1 and 3 ...
Growth and survival of Penaeus monodon postlarvae with different feeding regimes and stocking densities in earthen brackishwater nursery ponds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The effect of different stocking densities (50, 100 and 150/m2) and two feeding regimes (natural food, consisting mainly of lablab, and natural food plus artificial diet) on the growth and survival of Penaeus monodon ...
Effect of dietary fatty acids on the fatty acid composition of Penaeus monodon juveniles
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Six purified diets containing either pollack liver oil or a combination of dietary fatty acids (18:1ω9, 18:3ω3, 20:5ω3) at 5% level and a control (no lipid) were assessed for their influence on the fatty acid composition ...
Lecithin requirement of Penaeus monodon juveniles
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
An 8-week feeding experiment was carried out to determine the lecithin requirement of Penaeus monodon postlarvae. Six shrimps with initial mean weight of 0.11 g were stocked in oval fiberglass tanks in a flowthrough system ...
Evaluation of artificial feeds for shrimp (Penaeus monodon) production in brackishwater ponds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The experiment was conducted in fifteen 500-m2 brackishwater ponds to determine the response of Penaeus monodon juveniles fed with various artificial diets. Five treatments with three replicates each were: two commercial ...
Water quality criteria for farming the grass shrimp, Penaeus monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Physiological and growth effects of pH, salinity, temperature, heavy metals, pesticides and others on juvenile grass shrimp Penaeus monodon have been investigated to
determine the biologically safe concentrations. Optimal ...
Biology and ecology of Penaeus monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The giant tiger prawn, Penaeus monodon, the largest and most commercially important species among penaeids reaching 270 mm in body length or 260 g in weight, is suitable for culture in ponds and offers high market prices. ...
Induced ovarian maturation and rematuration by eyestalk ablation of Penaeus monodon collected from Indian ocean (Phuket province) and Songkhla lake
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Because of the difficulty involved in maintaining a supply of sexually mature female shrimp for larval production in hatcheries, experiments on induced ovarian maturation in tiger shrimp, Penaeus monodon by eyestalk ablation ...
