Genetics and biodiversity

The Genetics and Biodiversity Programme supports member states to improve scientific knowledge of aquatic genetic resources and to guide strategic planning in their management. The programme addresses both the conservation aspects of genetic resources and their responsible usage in aquaculture to minimise impacts on biodiversity and wild strains and to assist members to meet their obligations under international treaties.

The programme promotes international linkages between member states, capacity building, research programs to develop improved strains of finfish and shellfish, genetic characterisation of existing strains, adoption of new genetic tools and technologies and consortia regional programmes to address common issues, species and strains of value from conservation and/or aquaculture perspectives.

Key activities

Key activities of the programme include:

  • Building capacity in aquatic genetic resource management and application of new molecular technologies, tools and strategies.
  • Characterising aquatic genetic resources to discover species, stocks and valuable genomic resources.
  • Facilitating national and regional programs for domestication, genetic improvement and conservation.
  • Applying conservation aquaculture models to support diversification, fishery enhancement and in-situ conservation of indigenous fish species.
  • Facilitating responsible exchange of germplasm, safe propagation and access-benefit sharing.

Aspects of air-breathing fish farming practiced at Mathurapur-II Block, West Bengal, India

Climbing perch Anabas testudineus is a high-priced fish, nutritious and economically profitable for small- to medium-scale fish farmers, who can obtain fry from local paddy fields and low-lying inundated areas in late summer, monsoon and post-monsoon periods. Climbing perch is a facultative air-breathing fish that is able to move between water bodies by undertaking short migrations overland. This article describes techniques for climbing perch and major carp aquaculture, including use of biofloc systems, preparation of live feeds including mealworms, and some concerns regarding the hybridisation of native Indian strain of A. testudineus with an imported Vietnamese strain.

A free training course on mariculture technologies will be offered online via Zoom from 18 October to 5 November, by the Yellow Sea Fisheries Research Institute (YSFRI), People’s Republic of China. The course will cover genetics and breeding of mariculture species; large-scale propagation; disease control and prevention; nutrition research and feed development; technology for different farming models; equipment research, engineering and construction of farming facilities; quality and safety inspection technology for aquatic products. Space is limited, applications close 11 October.

Global Conference on Aquaculture Millennium +20

The GCA +20 was successfully held as a hybrid event from 22-25 September, with physical participation at the venue in Shanghai, China, and international participation via video conference. A total of 1,728 people participated in the event, of which 500 were physically present in Shanghai. A key output from the GCA +20, the Shanghai Declaration is a call to action that highlights the principles and strategic pathways to maximise the contribution of sustainable aquaculture in achieving the Sustainable Development Goals, with a special focus on “Leaving no one behind”.

Videos from the webinar on Culture-based fisheries for rural development

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.

Integrated taxonomy, conservation and sustainable development: Multiple facets of biodiversity

Focussed explorations from the ICAR-National Bureau of Fish Genetic Resources (NBFGR), an organisation mandated for cataloguing of genetic resources of India include surveys of various ecosystems ranging from fauna of deep sea to the high-altitude regions of the Himalaya, falling under diverse biogeographic zones and unexplored regions of the country, including North-eastern India, Western Ghats, Lakshadweep and the Andaman and Nicobar Islands. This article describes the results of these efforts, which include discovery of 14 new fish species and six new distribution records between 2015 to 2020.
