Among the freshwater catfishes, magur (Clarias batrachus) is in great demand in eastern and north-eastern India; it is revered as highly nutritious and therapeutic in nature. During May-June 2016, Sri Sayer Mohammad Sarkar, an experienced magur breeder and seed producer, has achieved success in producing induced-bred hybrid seed of Heteropneustes fossilis and Clarias batrachus. His breeding protocol and experiences in nursery and growout of hybrid catfish are shared in this article.

Murrels (snakeheads) are the third most important group of freshwater fishes in India after carps and catfishes. Murrels are the most common and dominant group of air breathing freshwater fishes and are highly regarded as food fish. Murrels have a pair of cavities in the pharynx that have folded linings, richly supplied with blood vessels for taking in air. These organs enable these fishes to survive out of water for a few hours or migrate from one pool to another.

Since 2009, tilapia aquaculture has been threatened by mass die-offs in Israel and Ecuador, which have been caused by a novel Orthomyxo-like (RNA) virus named Tilapia lake virus. This has been reported as a newly emerging virus that causes syncytial hepatitis of tilapia. An emergency regional consultation was held in Guangzhou, China from 27-28 September 2017 to discuss and plan actions on the overall prevention and management of this disease.

The potential for augmentation of fish production and fish-based eco-tourism in Arunachal Pradesh are immense. The landscape of the state is characterised by lofty mountains with snow-clad peaks, dense forests, turbulent streams and a rich diversity of flora and fauna. We review the potential of some of the lakes in the region to support trout fisheries for both recreational fishing and eco-tourism, with a view to providing job opportunities for highland communities.
