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 response of Penaeus monodon juveniles to varying protein/energy ratios in test diets
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)The response of Penaeus monodon juveniles (0.71±0.11 g) to varying protein/energy ratios in test diets was determined. Purified diets consisting of different levels of protein, lipid and carbohydrates were formulated. Two ... -
A review of maturation and reproduction in closed thelycum penaeids
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)Commercially important penaeids of the closed thelycum group belong to five subgenera of the genus Penaeus — Penaeus, Fenneropenaeus, Marsupenaeus and Melicertus that are almost exclusively Indo-West Pacific and Farfantepenaeus ... -
A review of the diseases of cultured penaeid shrimps and prawns with emphasis on recent discoveries and developments
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)The development of the commercial culture of penaeid shrimps and prawns has been accompanied by the occurrence of diseases of infectious and noninfectious etiologies. Many of the important penaeid diseases are caused by ... -
Role of bacteria and meiofauna in the productivity of prawn aquaculture ponds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)Detrital food chains, based on the use of manures and compost have been used in aquaculture for centuries. Heterotrophic bacteria convert organic detritus into protein and thus constitute an important food source in ponds. ... -
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 ... -
Seasonal abundance of Penaeid prawn seed in the Ennore estuary, Madras in relation to hydrography and lunar phase
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)An estimate of seed resources in the coastline, estuarine, and backwater bodies is an important prerequisite for developing prawn farming. A one-year (1983) survey on penaeid seed, based on tide and lunar periodicity, ... -
Seasonal and local occurrence of adults and postlarval stages of Penaeus merguiensis and Penaeus indicus in Batan bay, Philippines
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)Studies on seasonal and local occurrence of adults (spawners) and postlarval stages of Penaeus merguiensis and P. indicus in Batan Bay and Banate Bay, Aklan yielded the following results: 1) small-sized P. merguiensis and ... -
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 ... -
Studies on the artificial insemination and fertilization of grass shrimp, Penaeus monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)The culture of grass shrimp, Penaeus monodon has become a fast-growing enterprise in Taiwan since formulated shrimp feed was successfully developed in 1978. In 1983, the total postlarval production for stocking reached 600 ... -
Study on the larval rearing of Penaeus merguiensis
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)Nursing postlarvae of Penaeus merguiensis in the same tank as rearing always results in low survival rates, around 30%. One reason is that stocking density for P1 is too high for postlarvae grown to P20 size. Another reason ... -
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 ... -
Thermal tolerance of larval greentail prawn Metapenaeus bennettae (Raced and Dall) a comparison with school prawn Metapenaeus macleayi
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)The thermal tolerance of four larval stages of Metapenaeus bennettae was studied in the laboratory. Critical Thermal Maximum (CTM), One hour Median Lethal Temperature (lhLT50), and Median Resistance Time (MRT) were measured. ... -
The tolerance of Penaeus monodon eggs and larvae to fungicides against Lagenidium sp. and Haliphthoros philippinensis
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)The in vivo effect of mycostatic levels of fungicides against the fungi Lagenidium sp. and Haliphthoros sp. were tested on Penaeus monodon eggs and larvae. Hatching rate and survival of nauplii, zoeae, myses and postlarvae ... -
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. ... -
The use of microencapsulated feeds to replace live food organisms in shrimp hatcheries
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)An adequate supply of hatchery produced shrimp fry is the major constraint to the intensification and growth of shrimp culture practices. If even 20% of the more than 500,000 ha of the world's existing tropical and ... -
