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.

Future considerations for the domestication and breeding of penaeid shrimp

Domestication in livestock industries is the process in which animal populations change in response to the artificial environments of farming production systems. Significant and widespread economic gains have been achieved through genetic improvements made through domestication and selective breeding of commercially farmed shrimp species, particularly Litopenaeus vannamei. Different policies on the translocation of shrimp genetic resources have influenced the approaches to shrimp domestication in different countries. The present paper examines the different approaches.

Inbreeding and disease in shrimp aquaculture: A reappraisal and a caution

Tropical shrimp aquaculture is facing a disease crisis that may be propelled by an interaction between management practices that cause inbreeding, and the amplification by inbreeding of susceptibility to disease and other stresses. Broodstock accumulate inbreeding and lose genetic diversity when they experience bottlenecks or are chronically too small. The genetic lock is a practice that leads to inbreeding at farm level. Inbreeding may be amplifying the severity of diseases, including the major current threats.

Broodstock management in aquaculture: Long term effort required for regional capacity building

Asia produces nearly 90% of world aquaculture output. However, growth of the industry is increasingly constrained by various factors, including poor broodstock quality and genetic deterioration of domesticated stock. This has arisen in part from a general lack of planning, knowledge and skills in broodstock management. Capacity building across the region is urgently required for hatchery operators at different scales through information exchange, experience sharing and training.
