Coastal aquaculture in Thailand
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1994)
The coastal area has been explored for aquaculture and coastal aquaculture has expanded quite rapidly in Thailand. The economically important culture species are shrimp (Penaeus monodon), sea bass (Lates calcarifer), and ...
Overview of seafarming and searanching technology in Japan
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1994)
In 1989, artificial seed production was attained in 37 species of fishes, 16 species of Crustacea, 25 species of shellfishes, and 9 species of other fishery animals in Japan. Eighty species of fishery animal seed, including ...
Net cage culture of Lates calcarifer Bloch and other marine animals in Thailand
(Aquaculture Department, Southeast Asian Fisheries Development Center; International Development Research Centre, 1979)
Feeding experiments on sea bass, Lates calcaifer , have been carried out in nylon net cages in Songkhla, since 1971, to obtain information on: (1) growth rates; (2) survival rates; (3) food conversion rates; (4) environmental ...
Prospects of developing cage and pen culture in Sudan
(Aquaculture Department, Southeast Asian Fisheries Development Center; International Development Research Centre, 1979)
This paper describes the prospects of cage and pen culture in Sudan and recommends that a project for developing pen and cage culture techniques be started for marine and freshwater aquaculture.
Transgenic fish and aquaculture
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1995)
Transgenic fish species can be routinely produced by transferring foreign DNA into developing embryos via microinjection or electroporation. This technology offers an excellent opportunity for modifying or improving the ...
Health management in tropical aquaculture systems
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1995)
Health management strategies are very important in aquaculture. In Asia, health management practices are broadly similar for the various aquatic species that are cultured. These focus mainly on maintaining the good health ...
Farm-made feeds: preparation, management, problems, and recommendations
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
Making feeds exclusively for certain farming activities is quite common in the tropics particularly in the farming of fishes that feed low in the food chain. Feed preparation will depend on several factors such as availability ...
Effect of dietary astaxanthin and vitamin A on the reproductive performance of Penaeus monodon broodstock
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
Reproductive performance of pond-reared tiger shrimp given astaxanthin (100 mg/kg diet) and Vitamin A (20,000 IU) for 61 days was assessed in a 2x2 factorial experiment in a completely randomized design. Mean gonad index ...
Feed formulation and evaluation for semi-intensive culture of fishes and shrimps in the tropics
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
Semi-intensive farming systems account for about 70% of fish and crustacean aquaculture production in the tropics, employing semi-intensive feeding methods ranging from the use of low-cost pond fertilization techniques to ...
The use of chemicals in aquaculture in the People's Republic of China
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2000)
