Developments in sustainable shrimp farming in Southeast Asia
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2001)In Southeast Asia, shrimp aquaculture has been practiced for many years and is a traditional coastal farming activity in several countries. The recent trend has been towards more intensive forms of culture resulting in a ... -
Responsible aquaculture development for the next millennium
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2001)With the world population doubling in size from 3 to 6 billion people from 1960 to 1999 and currently growing at 1.33% per year (or an annual net addition of 78 million people), and expected to reach 7.3 to 10.7 billion ... -
Development of a brood stock of the jumbo tiger prawn, Penaeus monodon Fabricius
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1976)The full-scale cultivation of sugpo, P. monodon Fabricius, could only be realized if there is an assurance of continuous supply of fry. Obviously, a steady supply will depend largely on the availability of spawners. In ... -
A study on the milkfish fry fishing gears in Panay Island, Philippines
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)This study was conducted to obtain information for evaluating the present fry fishing practices and for understanding the behaviour of the fry. A description of the milkfish, Chanos chanos, fry fishing gears is presented. ... -
Traditional devices and gear for collecting fry of "sugpo" giant tiger prawn, Penaeus monodon in the Philippines
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)Eight typical devices and gears for catching the wild fry of the giant tiger prawn, Penaeus monodon, locally called sugpo are described and illustrated. There are three stationary ones vis. fry lure, fry filter net and set ... -
Weather observation at Tigbauan, Iloilo, Philippines from 1977 to 1980
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)The observations include: (1) air and sea water temperatures; (2) cloud cover; (3) rainfall; (4) wind direction and speed; (5) salinity; (6) sea wave condition. -
An annotated list of scientific and english common names of commercially important penaeid prawns and shrimps
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)There are 318 species of penaeid shrimps (Family Penaeidae) recorded in the world, of which about 80 species are placed under exploitation in fishing industry and/or cultivated artificially. The species under the genus ... -
A guide to induced spawning and larval rearing of milkfish Chanos chanos (Forsskal)
(Aquaculture Department, Southeast Asian Fisheries Development Center; International Development Research Centre, 1983)The techniques for the artificial propagation of milkfish (Chanos chanos ) developed at SEAFDEC are presented. These include: 1) capture and transport of spawners; 2) determination of sex and weight and maturity of fish; ... -
Intermediate culture of chinese prawn without feeding in nursery ponds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)The aim of the experiments is to find a new way to accomplish intermediate culture of the penaeid prawn in nursery ponds. Experiments have been carried out in prawn farms in Haiyang County, Shandong Province. Prawn fry ... -
An improved strategy for building brackishwater culture ponds with iron pyrite soils in mangrove swamps
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)The problems associated with acid sulfate soil limit the potential utilization of vast coastal areas of mangrove swamps for brackishwater aquaculture. There is an estimated 4.8 million ha of mangrove area in the ASEAN ... -
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, ... -
Characterization of ovarian maturation stages in wild unablated Penaeus monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)At least five wild-caught Penaeus monodon from various maturation stages (initially classified in vivo as 0, I, II, III, IV, V) were measured, weighed and dissected for histological and histochemical studies. The anterior ... -
Effect of carrageenan micro-binded diet on the larval stages of Penaeus indicus
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)At present, most hatcheries depend on live food like diatoms, Chlorella, rotifer and brine shrimp to rear the larval stages of various penaeid species. Mass production of live feed requires much space (tanks) and labor, ... -
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 ... -
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 ... -
Effect of various levels of squid protein on growth and some biochemical parameters of Penaeus japonicus juveniles
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)An unknown growth factor previously suspected in squid meal was found in the protein fraction of squid (Loligo vulgaris). It is clearly different from hydro-alcohol-soluble feed attractants that are also present in squid ... -
The integrated use of artemia in shrimp farming
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)The use of freshly hatched Artemia nauplii in penaeid hatcheries is a common practice, although a broader application of Artemia in shrimp farming is gaining more and more interest. In this regard, an integrated use of ... -
Imperatives for the future development of prawn culture in the Cochin backwater system (Kerala, India)
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)A traditional system of prawn culture practised in the Cochin Backwater System, the largest backwater system in Kerala State, has an estimated yield of 4,000 tons from about 4,500 ha. Governmental investments to encourage ... -
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 ... -
