Mahseer sanctuaries of Meghalaya: A conservation and recreational perspective; Impacts of climate change on aquaculture in Vietnam: A review of local knowledge; Simple means of water aeration adopted by progressive fish breeders in West Bengal, India; Breeding striped snakehead (Channa striata) using the concrete tank method in the Cangkringan Area, Special Region of Yogyakarta; NACA Newsletter.

This article presents available information regarding the present status of chocolate mahseer and the conservation measures been undertaken in the East Garo Hills of Meghalaya. A total of 54 sanctuaries have been established since 2012 in Garo, Khasi and Jaintia hills under the Meghalaya State Aquaculture Mission project of the Fish Farmers Development Agency. The sanctuaries have been established with the objective to preserve and enhance aquatic biodiversity, protect indigenous fish species, preserve breeding and feeding grounds, and serve as tourist attractions to provide livelihood opportunities.

Vietnam has a vast coastline which exposes it to typhoons and flooding. Farmers are at the frontlines of experiencing climate change as their livelihoods are intrinsically linked with the natural environment. Our study collected local knowledge of aquaculture farmers living in South Central Vietnam. The purpose of the interviews was to gather firsthand knowledge on current climate change impacts experienced by farmers, as well as which climate change threats they are most concerned about, and how they are adapting to these threats.

In India, West Bengal is the leading state in hatchery-based seed production (spawn, fry, advanced fry) of major carps and other economically important freshwater fishes. Dissolved oxygen is the most critical parameter of water quality and basic necessity in fish hatcheries, nursery and grow-out ponds. Hatchery fish seed production can be limited by the dissolved oxygen content of circulating water. Progressive fish breeders in villages of West Bengal have overcome and eliminated this problem by designing simple but effective means of water aeration to improve dissolved oxygen in hatchery water supplies, maximising survival of fertilised eggs, hatchlings and spawn. This article describes some of the techniques that have been adopted using low-cost and recycled materials.

The striped snakehead (Channa striata) is a species of swamp fish that has a high economic value. Intensive fishing has reduced the wild populations. Hatchery production of this species has the potential for both commercial aquaculture supportive breeding programmes to conserve fish resources and increase the natural population. Below we describe a protocol we used for controlled spawning and hatchery operations for striped snakehead.

The 83rd edition of the Quarterly Aquatic Animal Disease report contains information from twelve governments. The foreword discusses the upcoming 11th Symposium on Diseases in Asian Aquaculture (DAA 11), which will be held from 29 September to 2 October 2020, at the Borneo Convention Center, Kuching, Sarawak, Malaysia.

Join us for the aquaculture event of the decade! 18th Meeting of the Asia Regional Advisory Group on Aquatic Animal Health; New Director General of the Department of Fisheries, Thailand; Thailand holds National Sea Bass Fair; Tuskfish CMS 2.0 is available; Regional consultations on strengthening aquaculture governance and demographic changes in fishing communities; INFOFISH World Shrimp Conference and Exposition.

The 35th Session of Asia-Pacific Fishery Commission has identified the lack of effective governance as a major threat to sustainable aquaculture growth for greater contribution to achievement of the Sustainable Development Goals. The objectives of the consultation were to: Share the results of country studies on aquaculture governance in respective countries; identify gaps, issues and challenges in aquaculture governance; and recommend strategies and actions to improve and strengthen aquaculture governance.
