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. ...
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 ...
The effects of stocking densities on growth and survival of Penaeus vannamei in cow manure-enriched ponds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Ecuadorian Penaeus vannamei were stocked in eight dirt ponds (approximately 163 m2) at four different types of density, i.e., 5 shrimp/m2, 10 shrimp/m2, 15 shrimp/m2, and 20 shrimp/m2. The initial body weight ranged between ...
Aquaculture development in Singapore
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1988)
The trend of fish production in Singapore is towards increasing contribution from marine and brackishwater aquaculture. Aquaculture production in 1986 represented 6.8% of local fish production. It is envisaged that this ...
Overview of penaeid culture research: Impact on commercial culture activity
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The paper gives a comprehensive review of the state of penaeid culture research, its impact on commercial activity, and the major research efforts required to solve remaining problems. After providing a brief historical ...
Nutrition of penaeid prawns and shrimps
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Since Hudinaga succeeded in the artificial hatching and subsequent culture of larvae of the prawn, Penaeus japonicus, techniques for rearing this prawn from hatching to commercial sizes have been improved in Japan 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, ...
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 ...
A new approach in intensive nursery rearing of penaeids
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The need for a nursery phase between the hatchery and the growing pond to avoid mortalities of young postlarvae, and provide a better assessment of stocked animals is general in crustacean aquaculture.
The Centre ...
