Variation in tissue lipid content and fatty acid composition during ovarian maturation of unablated and ablated Penaeus monodon broodstock
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The tissue lipid content and fatty acid composition in the hepatopancreas, tail muscle and gonad of unablated and ablated Penaeus monodon were determined. Females at various stages of maturity were collected from offshore ...
Earthworm, marine annelids and squid as feed ingredients in formulated diets for juvenile Penaeus monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Earthworm and annelids were incorporated in diets for Penaeus monodon juveniles (mean weight 0.54 g) either in wet or dry form. These protein sources were added in amounts needed to replace 10% of the animal source of ...
Effects of some water-soluble vitamins on the growth of Penaeus monodon juveniles
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The response of Penaeus monodon juveniles (ave. wt.= 0.076 g) in terms of survival and growth rates to vitamin test diets was observed in a 35-day feeding experiment. The prawns were reared in 60-ℓ oval tanks containing ...
The influence of temperature and salinity on oxygen consumption of Penaeus monodon postlarvae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The effect of salinity and temperature on oxygen consumption at different developmental ages of Penaeus monodon postlarvae (P5 to P60) was studied. The design was a 2 × 5 factorial, using two levels of temperature (15 and ...
Lipids and essential fatty acids in the nutrition of Penaeus monodon larvae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Total lipid levels and fatty acid distribution during larval development of Penaeus monodon were determined. Larvae were cultured utilizing standard rearing procedures and feeding schemes adopted by the Crustacean Hatchery ...
Carbohydrate requirements of Penaeus monodon juveniles
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Penaeus monodon juveniles (initial mean weight=0.62 g) were fed semi-purified diets containing 10, 20 and 30% trehalose, sucrose or glucose for eight weeks. Results showed that shrimps fed 20% trehalose gave the highest ...
Survival, growth and production of white shrimp Penaeus indicus in brackishwater ponds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
This study was conducted in 4 one-ha ponds, 70-100 cm deep and 2 two-ha ponds, 40-70 cm deep to evaluate the survival, growth and production of white shrimp, Penaeus indicus stocked at 50,000/ha and cultured within a period ...
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 ...
Observations on the nauplii production from wild, cultivated and mixed populations of the blue shrimp (Penaeus stylirostris)
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Due to low nauplii production from cultivated broodstock and to minimize dependence on wild stock, an experiment was run in which four treatments, consisting of combinations of 400 adult blue shrimp (Penaeus stylirostris) ...
