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.

Join us for the SDG-aligned Artemia Aquaculture Workshop, 22 September

Join us online at the SDG-aligned Artemia Aquaculture Workshop, which will be held on 22 September, via Zoom. With the expansion of hatchery production, the demand for Artemia cysts has continued to increase and annual consumption is now estimated at 3,500 – 4,000 tonnes, underpinning the production of over 10 million tonnes of high-value aquaculture species. Approximately 90 percent of the current Artemia production is harvested from inland salt lakes. The purpose of the Artemia workshop is to explore needs and opportunities for a new international initiative to guarantee a more sustainable provision of Artemia, both from natural sources and from controlled extractive Artemia farming integrated with salt production and other fish/crustacean aquaculture.

Videos from the webinar Status of the use of Artemia cysts in fish and crustacean hatcheries

Videos from our recent webinar Status of the use of Artemia cysts in fish and crustacean hatcheries around the world are now available on NACA's Youtube channel. Please consider subscribing for more technical aquaculture content!

Webinar: Status of Artemia cyst use in fish and crustacean hatcheries

Join us on 2 September at 12 noon GMT for a free webinar on the Status of the use of Artemia cysts in fish and crustacean hatcheries around the world. The webinar is facilitated by the International Artemia Aquaculture Consortium (under formation). The webinar will document differences in practices used by fish and crustacean hatcheries in the use of Artemia cysts for the preparation of live feeds. Speakers include technical experts using Artemia in the production of shrimp, freshwater prawn, mud and mitten crabs, seabass, sabream and other marine fish from Bangladesh, Brazil, China, Ecuador, Greece, India, Spain, and Thailand. Participation is free but registration is required.

Aquaculture for livelihoods and food security in North-western India

In the north-western states of India there is great scope for aquaculture to generate employment opportunities, improve the socio-economic status of farming communities, furnish additional food and nutritional security and boost the national economy. This article describes the present state of Indian aquaculture and prospects for increasing production through diversification, use of village/community ponds and inland saline aquaculture of shrimp and other species, along with major concerns and action plans.

An insight to red tilapia breeding and culture: A a farmer advisory

The aquaculture of red tilapia is proving to be highly successful due to its attractive colour, faster growth rate and good market demand. Expansion of the industry will depend on adequate supply of quality seed. This article describes the status of red tilapia aquaculture and good practices in broodstock management and nursery rearing using hapa systems and all-male seed production techniques, including hapa installation, breeding, egg collection and related issues.

Report of the Nineteenth Meeting of the Asia Regional Advisory Group on Aquatic Animal Health

This report summarises the proceedings of the 19th meeting of the Advisory Group, held 26-27 November 2020 via video conference. The group's role includes reviewing disease trends and emerging threats in the region, identifying developments in global aquatic disease issues and standards, evaluating the Quarterly Aquatic Animal Disease Reporting Programme and providing guidance on regional strategies to improve aquatic animal health management.
