28th NACA Governing Council, Dhaka, Bangladesh; register for the First Regional Training Course on Culture-based Fisheries; 11th Indian Fisheries and Aquaculture Forum, Kochi, 21-24 November; audio recordings for regional feed consultation now available; tilapia lake virus; Proceedings of the International Symposium on Aquatic Animal Health and Epidemiology for Sustainable Asian Aquaculture; ICAR-CIBA launch "Vanami Shrimpapp", a mobile app on Pacific white shrimp (Penaeus vannamei) farming; Pakistan officials train on aquaculture certification.

These are the proceedings of a symposium convened by the ICAR National Bureau of Fish Genetic Resources, Lucknow, India, from 20-21 April 2017. The symposium included presentations from national and international experts on aquatic animal epidemiology and related disciplines to address a range of risk factors that catalyse horizontal spread of disease, spread of transboundary pathogens and increased disease susceptibility, thereby contributing to strengthening of surveillance efforts, especially in the Indian context.

The 73rd edition of the Quarterly Aquatic Animal Disease Report contains information from 14 governments. The foreword provides a disease advisory on tilapia lake virus (TiLV), an emerging threat to farmed tilapia in the Asia-Pacific region.

A regional consultation on aquaculture feed production and use in Asia-Pacific was held from 7-9 March 2017. The consultation reviewed the current situation of aquaculture feed production and use, sourcing of ingredients, policy and research needs. This collection contains audio recordings of the technical presentations made by experts, international organisations, the private sector and governments in the region. The report of the consultation is in press and will be made available for download in due course.

Inspiring story of aquaculture in Sikkim - a journey from conservation to farming; farming of scampi and tiger shrimp together - a case study from West Bengal; Labeo pangusia - a candidate for diversification of hill aquaculture; sustainability of an integrated livestock-fish-crop farming system as a small scale enterprise; sustainable coastal aquaculture in India; potential scope and prospects of domestic fish market in Chhattisgarh.

Sikkim is a small Himalayan state of India with three climatic zones ranging from tropical to temperate to alpine. The moderate-cool and warm agro-climatic zones are suitable for farming rainbow trout and exotic carp species, while brown trout hatchery and ranching can be conducted in the alpine areas. We report on the status of exotic carp and trout farming in Sikkim including farming practices, constraints faced by local farmers and possible solutions.

We report on an Indian farmer co-culturing tiger shrimp Penaeus monodon and the giant freshwater prawn, Macrobrachium rosenbergii. The farm utilises wild-caught riverine seed, stocked at a relatively low density and fed on a Macrobrachium pellet which P. monodon also accepts.

Labeo pangusia is a highly prized hill stream carp found mainly in the deeper pools of upland streams. Heavy fishing pressure has led to depletion of wild populations in recent years and the species is likely to become threatened if a conservation strategy is not developed. We report on an investigation into the reproductive biology of this species and on the result of successful induced breeding trials.

We examined the sustainability and economic viability of a model integrated livestock-fish-crop farming system developed by the Fisheries Research Centre, Assam Agricultural University, over an extended period of 13 years. The system was developed as an ecologically sustainable alternative technology for small and margin farmers. It incorporates two livestock components, pig and poultry, with horticulture and carp polyculture. Analysis of cash flow and benefit-cost ration revealed the system to be economically sustainable over the long term.

Coastal aquaculture in India was historically focussed mainly on tiger shrimp farming (Penaeus monodon) but production issues and disease led to the introduction of SPF Pacific white shrimp (L. vannamei) in 2009. A robust technical and legal framework was established by the Coastal Aquaculture Authority. Improved regulation has improved sustainability of the sector and underpinned production, with farmed Pacific shrimp output rising from 1,731 tonnes in 2009-2010 to 353,413 tonnes in 2014-2015.
