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.

Impacts of climate change on aquaculture in Vietnam: A review of local knowledge https://enaca.org/?id=1089&title=impacts-of-climate-change-on-aquaculture-in-vietnam

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.

Simple means of water aeration adopted by progressive fish breeders in West Bengal, India https://enaca.org/?id=1088&title=simple-means-of-water-aeration

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.

Breeding striped snakehead (Channa striata) using the concrete tank method in the Cangkringan Area, Special Region of Yogyakarta https://enaca.org/?id=1087&title=breeding-striped-snakehead-channa-striatus

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.
