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.

Farming of the anadromous shad, Tenualosa ilisha: Signs of taking off in India https://enaca.org/?id=1179

The andadromous shad Tenualosa ilisha (also known as hilsa) is an economically important food fish in south and southeast Asia. Populations of the species are declining globally, largely due to overexploitation and habitat modification. Its fishery has drastically declined in the Bay of Bengal bordering India. Considering the excessive demand and very high market price there have been efforts for domestication and farming of the species in India. Early efforts were not measurably successful. However, momentum on developing captive breeding and farming technologies for this species has been re-invigorated with research funding from the Indian Council of Agricultural Research.

Imparting skill on formulated fish feed preparation to women’s self-help groups in villages – an experience https://enaca.org/?id=1178

Preparation of locally made floating pelleted fish feed can be a profitable and sustainable income generating entrepreneurial activity for women's self-help groups in rural areas. Using such feed can also help small-scale marginal fish farmers to improve production and reduce their operating costs. This article describes initiatives to train women's self-help groups in formulated feed production in West Bengal, India.

Opinion: Benefits of animal welfare in Indian aquaculture https://enaca.org/?id=1177

Parasites and disease are amongst the greatest issues affecting Indian aquculture, incurring substantial economic losses every year. Due to disease risk, some farmers may use antibiotics as a prophylactic measure, with consequent risk of increasing anti-microbial resistance. Organic aquaculture has the potential to allow reduced chemical inputs, but must be coupled with other paradigms to alleviate disease issues. The Fish Welfare Initiative believes that measures to improve animal welfare, in particular water quality and stocking density, can contribute to improved animal health outcomes.
