Some varieties of freshwater fish have low growth potential but remain economically attractive due to market preferences. The endangered catfish Horabagrus brachysoma is one such fish, which has limited production but high market demand, and a number of favourable biological characteristics. This article provides guidelines for the culture of this catfish in captivity including for the breeding, nursery, stocking and growout, including advice on pre- and post-stocking practices, harvesting and health management.

Despite their abundance at one time in India and other Asian nations, wild mahseer populations have been declining because of degradation of aquatic ecosystems, urbanisation and indiscriminate fishing. Wild mahseer are populations are presently struggling for their mere existence.

An international workshop on mahseer conservation, propagation and rehabilitation will be held in Bhimtal, India from 23-24 April 2018. The workshop is organised by the ICAR-Directorate of Coldwater Fisheries Research in collaboration with the Coldwater Fisheries Society of India.

BRAQCON 2019 wil cover latest research and development in the broader themes of the conference in the form of special sessions, contributed papers, expert group discussions and brainstorming on issues facing aquaculturists and ecosystem managers in India and around the world. The conference themes include: Brackishwater ecosystems, estuarine biodiversity and conservation; aquaculture production systems; larviculture; fish and shellfish nutrition; environment and climate change; aquatic animal health; socio-economic and livelihood issues; and aquaculture genetics and biotechnology.

This collection contains video recordings of the lectures from the Regional Training Course on Culture-based Fisheries in Inland Waters, held at Nha Trang University, Vietnam. The objective of the course was to provide participants with the skills to assist local communities to plan and manage culture-based fisheries; a relatively simple and low cost technology that can deliver nutritional and economic benefits to rural communities with few livelihood options. The course was sponsored by the United Nations University Fisheries Training Programme.

Better management practices for stocking and transport of seed for culture-based fisheries.

The first ever Regional Training Course on Culture-based Fisheries in Inland Waters was held at Nha Trang University from 30 October to 8 November. The objective of the course was to provide participants with the skills to assist local communities to plan and manage culture-based fisheries. These practices are an example of a relatively simple and low cost technology that can deliver nutritional and economic benefits to rural communities, which often have few livelihood options.

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.

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.

The Asian Institute of Technology (AIT) is launching a new Certificate programme on Sustainable Asian Aquaculture via the AARM Academic programme, for one semester beginning August 2017. This certificate programme is a combination of well-designed course work and hands-on experience in specialised areas (fish/shrimp hatchery or farming). The programme is useful for both students (with credit transfer) and for working professionals and entrepreneurs (without credits).

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.

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.

The fourth major international event on giant freshwater prawns was organised by the Asian Institute of Technology from 20-24 March 2007. The conference, organised by Salin Krishna and Michael New, built on a series of highly successful events that trace back to the very beginnings of the industry. The first conference, Giant Prawn 1980 brought together all those involved in freshwater prawn research and farming for the first time and set many priorities for future research and development.

Bangana dero is one of the most popular indigenous minor carps in the north eastern states of India, fetching triple the market prices of Indian major carps. B. dero is a bottom feeder and feeds on insect larvae, molluscs, algae, zooplankton and detritus. Over the last two decades the occurrence of wild juveniles of this fish in Indian rivers has fallen drastically. A protocol for induced breeding, larviculture, nursery rearing and growout including polyculture of B. dero is described.

In Nepal, low quality and seasonal access to fish seed is an important restriction on the development of the aquaculture sector. Commercialisation of fish farming cannot progress rapidly in the absence of critical inputs and a regular supply of quality fish seed is an integral requirement for the transition of fish farming from a subsistence activity to a commercial enterprise. Participatory market chain approaches are a key tool for the social and economic improvement of farmers and market participants.

The objectives of this project were to i) develop a guidebook in English on "Farmer-to-farmer extension approaches for small-scale aquaculture" and ii) to translate the developed guidebook into selected local dialects in Asia-Pacific and other regions (e.g. Africa). The project made use of the significant results from the JICA projects in Cambodia, Benin and other countries on farmer-to-farmer extension approaches on technology extension for small-scale farmers. The book is available in eleven languages (English, Arabic, Bahasa Indonesia, Burmese, French, Khmer, Loatian, Malay, Nepali, Thai and Vietnamese.

The objective of this manual was to provide basic guidelines for the hatchery production of Pa Phia (Labeo chrysophekadion) fingerlings. It includes information on managing and spawning broodstock, genetic guidelines, egg incubation, hatching larviculture and fry rearing. Although the guidelines were specifically developed for production of Pa Phia at government hatcheries in the Lao PDR, they may be applied to other, related, species and could be adopted and commercialised by the private sector hatcheries

This publication is the major output of a regional programme jointly implemented by FAO and NACA in 2015 to document and disseminate successful practices that contribute to the sustainable intensification of aquaculture in the Asia-Pacific region. Twelve practices are described that contribute to at least one of the following: Improved production and resource use efficiency (land, water, feed, energy); improved environmental benefits; strengthened economic viability and farmers' resilience; and improved social acceptance and equity.
