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 effect of different levels of vitamins premix in the diet of African catfish (Clarias gariepinus) fingerlings
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
The present study was conducted to determine the growth and survival of African catfish (Clarias gariepinus) fingerlings fed diets with various levels of vitamin premix. The fingerlings (mean weight, 1.55 to 2.12 g) were ...
Effects of dietary carbohydrate, lipid and energy on the growth, feed efficiency, and tissue composition of bighead carp (Aristichthys nobilis) fry
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
The utilization of dietary carbohydrate and lipid as energy sources for bighead carp (Aristichthys nobilis) fry and various protein:energy ratios were investigated in a 2x3x3 factorial feeding experiment. Semi-purified ...
Aquaculture in Malaysia
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1995)
Aquaculture in Malaysia is experiencing rapid growth. Total production in 1992 amounted to 79,699 tons valued at RM 207.4 million. These figures are 23% and 25% higher than the previous year's. Semi-culture of the cockle ...
Bivalves
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1994)
Mollusc research at the Aquaculture Department of the Southeast Asian Fisheries Development Center from 1989 to 1991 was primarily focused on the highly exploited window-pane oyster, Placuna placenta Linnaeus. Other species ...
Nutritional requirements of commercially important shrimps in the tropics
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
The culture of tropical shrimps has gained greater economic importance particularly among Southeast Asian countries. As shrimp fanning moves from low-input, low-technology operation to the intensive and even highly intensive ...
