Free registration: Belt & Road Forum for International Freshwater Fishery Industry Innovation, 16 August

An online forum will be held on 16 August to enable technical exchange between policymakers, fishery extension officers, researchers and entrepreneurs in development of the freshwater fisheries industry through technology innovation.

The forum will focus on innovations and developments in freshwater fishery biotech, breeding, culture models, digitisation, and industrialisation, featuring presentations and discussions from experts of international organisations, the Chinese Academy of Sciences, Chinese Academy of Engineering, universities and entrepreneurs in virtual exchanges and discussions. Participation is free but registration is required.

Webinar: Culture-based fisheries for rural development

Join us on 31 May for a free webinar on Culture-based fisheries for rural development, with leading experts from the Asian region. Culture-based fisheries (CBF) are practices to enhance fish stocks in waters that don't have enough natural recruitment to sustain a fishery. CBF practices are usually applied in small water bodies such as village dams and irrigation reservoirs. Fish growth is driven by the natural productivity of the waters, foraging on natural food supplies. The simplicity and low capital requirements of CBF make it easy for farming communities to learn and adopt.

Exotic trout fisheries resources and potentialities in Uttarakhand

Commercial trout farming in Uttarakhand has advanced progressively during the last decade and has become a profitable occupation among the rural masses especially in the colder regimes where no other fish farming has possibilities. The rainbow trout here plays the most dominant role as a commercially important candidate species for culture in this hill locked Himalayan state of India. This article describes the current status of trout fisheries resources and trout aquaculture in Uttarakhand, and their potential further development.

Trout fisheries resources and potentialities in the Menchukha region of Arunachal Pradesh

The success of any aquaculture project or fish farm depends to a large extent on selection of a suitable site. Site selection using the conventional method, based on very limited data, can result in inaccurate information and cause discrepancies among the implementing agencies. The utilisation of remote sensing and geographic information systems can provide a useful source of additional information. This article provides a GIS-based analysis of the suitability of sites for trout farming and the establishment of sport fisheries in the Menchukha valley, Arunachal Pradesh.

Expert Consultation on Invasive Alien Fish Species, 19 December, New Delhi

An Expert Consultation on Invasive Alien Fish Species: Need for a Risk Benefit Assessment and Management Framework for Healthy Freshwater Systems will be organised on 19 December 2018 in New Delhi, India. The consultation will flag the need for an equilibrium between access to non-native germplasm and the minimisation of risk to ecosystems and native fish diversity from such introductions. As a major outcome, an objective tool is expected to be developed, which can be used to evaluate prospective introductions and support decision making.

Mahseer in recreational fisheries and ecotourism in India

Mahseer are the most popular game fish amongst anglers in India, with a reputation as one of the toughest fighters amongst freshwater sports fish. In this article, we have made an attempt to compile information on recreational mahseer fisheries in India. The importance of the mighty mahseer as a game fish is told through the perspectives of active anglers and the visions of stakeholders and researchers in conservation and ecotourism are presented.

Trout fisheries in the uplands of Arunachal Pradesh: Resources and opportunities

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.

Inspiring story of aquaculture in Sikkim: A journey from conservation to farming

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.

Giant Prawn 2017

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.

General aspects of stock enhancement in fisheries developments

In recent years, stocking programs have been subjected to substantial criticism due to perceived impact of hatchery-bred fish on genetic structure and fitness of wild stocks, transfer of disease, introduction of exotic species and non-target species, and their effects on other aquatic species and the environment. To maximise the potential benefits to fisheries from stock enhancement a responsible and ecologically sustainable approach should be adopted for all stocking programs.
