Magical role of live foods in boosting spawn survival of climbing perch: A success in the farmer’s field

Climbing perch inhabit water bodies ranging from fresh to brackish waters across a wide range of environments, and are widely distributed throughout south and southeast Asia through to southern China. In India it is prized both as a foodfish and as a traditional medicinal food. This article describes the induced breeding of climbing perch and the interaction of scientists and farmers to improve survival of larvae and fry in through the use of live feeds (rotifer) in small-scale hatcheries in India.

Some facts on cannibalism in Wallago attu and its management during captive seed production

Wallago attu is a large catfish reaching 45 kg found in the Indian subcontinent, Thailand, Vietnam, Cambodia and Indonesia. Early attempts at captive production encountered high losses due to cannibalism during early life stages. This article discusses the causative factors governing cannibalism in this catfish, including rapid transfer from live to commercial feed, size differences during stocking, seasonal changes, feeding at long intervals, high density rearing, feed distribution, feeding method and size of feed, and management strategies for minimising losses during the seed rearing period.
