Recreational fisheries in Uttarakhand

Establishing recreational fisheries in Uttarakhand's highland lakes and river systems offers new opportunities to generate livelihoods and income for hill people. The development of catch-and-release sport fisheries can also contribute to conservation of aquatic biodiversity through development of captive breeding technologies, supportive breeding based stock enhancement, and community participation in management of both fishery and habitat. This article describes established and emerging sport fisheries in the highlands of Uttarakhand including for mahseer, goonch and brown trout. It also addresses as yet unrealised opportunities for establishment of recreational fisheries identified through geoinformatic approaches, and partnerships between local communities and government in natural resource management.

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.

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.
