A Regional Expert Consultation on Genetically Responsible Aquaculture was convened by the ICAR National Bureau of Fish Genetic Resources and NACA, from 26-27 February. The immediate objective of the consultation was to discuss mechanisms for establishing quality seed production systems to improve hatchery and on-farm genetic diversity. A long-range objective is to establish networks of registered broodstock holdings. Linked via IT systems, such networks will form a virtual global aquaculture gene pool that can, collectively, sustain high genetic diversity and adaptive capacity, while checking inbreeding depression.

The 79th edition of the Quarterly Aquatic Animal Disease report contains information from eleven governments. The foreword discusses the outcomes of the 17th Meeting of the Asia Regional Advisory Group on Aquatic Animal Health, held in Bangkok, 13-14 November 2018.

The ICAR-National Bureau of Fish Genetic Resources, Lucknow, India is conducting a School on Aquatic Animal Epidemiology and Disease Surveillance from 1-6 March, 2019. Five seats are available in the school for researchers from NACA member countries (outside of India) on first-come first-served basis. Participants should be nominated by research centres participating in NACA or by member governments. Accommodation, hospitality and meals will be provided for the duration of the training. Travel grants are not available. Please apply / express interest by 13 February 2019.

Current status of freshwater cage aquaculture in India; Fattening of mud crab Scylla serrata in estuarine region of south-eastern West Bengal; Aquaponics - sustainable farming method in the fight against hunger; aquatic invasive apple snails (Pomacea spp.) in Timore-Leste - current status, spread and management in rice fields; NACA Newsletter.

Initial attempts to develop freshwater cage aquaculture in India focussed on air breathing catfish and Indian major carps in the Yamuna and Ganga rivers, with later efforts in several large reservoirs. Cage-based aquaculture in inland waters is currently being promoted by some state governments with a view to enhancing fish production. This article examines the history of cage aquaculture in India and some of the factors to be considered in cage design and site selection.
