Hepatopancreas cells as monitor cells for the nutritional value of prawn diets in aquaculture
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The hepatopancreas is considered to be the central organ of metabolism in decapod Crustacea. It is a system of blind tubules consisting of four cell types. The E-cells at the summits of the tubules develop into R-cells ...
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 ...
The biology of Penaeus monodon in the capture fisheries off orissa coast, India in the context of occurrence of natural broodstock
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The tiger prawn of India, Penaeus monodon Fabricius has a differential distribution in the two coasts of India. Density is high in the northeastern part of the Bay of Bengal gradually declining towards the mid-east and ...
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 ...
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 ...
Recruitment of postlarval penaeid prawns in the Vellar estuary, South India
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The northern bank of Vellar estuary (Parangipettai, India) is ideal for postlarval penaeid prawn recruitment. The annual recruitment, distribution and the substratum preference of postlarval immigrants at three different ...
The production economics of an integrated prawn hatchery-floating nursery project
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The paper aims to present an economic evaluation of an integrated prawn (Penaeus monodon) hatchery-floating nursery project using standard economic tools and methods of analysis. The data used in the analysis were taken ...
Environmental physiology of the prawn Penaeus (melicertus) latisulcatus
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
There are a number of intrinsic and extrinsic factors which affect the normal routine activity of the prawn. The present study attempts to elucidate the optimum levels of various environmental factors for the culture of ...
