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.

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.

[Postponed]: 2022 Global Forum on Sustainable Development of Fisheries

Update: The forum has been postponed, we will announce the new date in due course. In the meantime, you are welcome to register and we will email you when the new arrangements are available. Apologies for the inconvenience - Ed.

A free online forum will be organised by the Agriculture Trade Promotion Center, Ministry of Agriculture and Rural Affairs of the People’s Republic of China, and Yellow Sea Fisheries Research Institute, Chinese Academy of Fishery Sciences. The forum aims to strengthen international exchange and cooperation in aquatic trade, promote high-quality development of fisheries, disseminate advanced concepts, technologies, and models of aquaculture in the Asia-Pacific region and Silk Road countries, and promote the health and sustainable development of global fisheries. Participation is free but registration is required.

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.

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

Video recordings of technical presentations from the webinar on Culture-based fisheries for rural development (31 May 2021) are now available on Youtube. Presentations cover technical constraints, the socio-economic and impact on communities, micro-nutrient security, monitoring and evaluation, improving water quality through stocking selected species, biodiversity considerations, and success stories.
