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 ...
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 ...
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 ...
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 ...
Effect of temperature and salinity on the hatching of eggs and larval development of sugpo, Penaeus monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Incubation of Penaeus monodon eggs and rearing of different larval stages were undertaken at nine temperature-salinity combinations. The eggs, nauplii, zoea and mysis from one spawner kept as stock culture at ambient ...
The use of haptophyceae in rearing experiments on larval Penaeus orientalis
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The food value of five clones of Haptophyceae, Coccolithus pelagicus, Dicrateria zhanjiangensis, Isochrysis galbana, Tahitian Isochrysis aff. galbana, and Pseudoisochrysis paradoxa were tested for larval Penaeus orientalis. ...
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 ...
Molt staging in adult Penaeus monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Changes and formation of cuticular layers and setae bordering the uropods and endopodites of the pleopods of adult Penaeus monodon were examined under a light microscope. Observations and photographs were made at 0, 12 and ...
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 ...
