Genetics and Biodiversity

74879 views

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.

Free online Training on Mariculture Technologies for the Asia-Pacific Region

The Yellow Sea Fisheries Research Institute, Chinese Academy of Fisheries Sciences and NACA are organising a free online training course on mariculture technologies, to be held from 21-25 September 2020. The programme will cover breeding, disease control and prevention, nutrition and feed research, breeding model construction, farm technology development, engineering, quality, safety and inspection technology for aquatic products. The course is open to government officials, researchers, enterprise managers and technicians from developing countries. The deadline for applications is 19 September 2020.

Regional Workshop on Underutilized Fish and Marine Genetic Resources and their Amelioration – Proceedings and Recommendations

The workshop was held from 10-12 July 2019, Colombo, Sri Lanka. The objectives of the workshop were to i) assess the current status of underutilised aquatic genetic resources at the regional level and to assess R&D status of priority species with potential for use in food and agriculture; ii) discuss knowledge gaps and regional priorities concerning underutilised genetic resources and create awareness on their role and value for diversification of food supplies and livelihoods; and iii) formulate strategies for strengthening the institutional framework for management and conservation of genetic resources at the regional level.

Lovesome chum of the aquarium are wreaking havoc in the East Kolkata Wetlands, India

Loricariid catfish species of the genus Pterygoplichthys, known in the aquarium trade as 'plecos' and 'algae eaters', have extensively invaded and proliferated in the East Kolkata Wetlands in West Bengal. Loricariids have capacity to alter the ecosystem and biodiversity of invasion sites, by physically altering the invaded habitats and by competing with native animals for food and space. The aquarium trade pathway is the most significant source of loricariid introductions globally. This article discusses the invasion of loricariid catfish in the East Kolkata Wetlands, and the environmental and economic impact on local fishers.
