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.

Expert consultation on genetic erosion risk analysis for shrimp diseases in Asia

Shrimp aquaculture in tropical regions is facing a disease-induced catastrophe of lost production. There is reason to believe that current broodstock management practices may induce genetic erosion that increases susceptibility to disease and vulnerability to epizootics. The basic tenet for this Expert Consultation is that an important aggravating factor in the disease crisis is an agro-economic system that locks shrimp breeders, hatcheries and farmers into behaviour that induces high levels of inbreeding.

Aquaculture in a genetic plunge towards extinction?

Artisanal shrimp aquaculture is in a disease-induced crisis of lost production, into which are falling farms, gene pools adapted to farms, and small-hold farming as a way of life. Rising levels of inbreeding and an exceptionally strong, positive relationship between inbreeding and disease which is described here. The root cause is social: a nexus of human behavior in which breeders protect their intellectual property by generating inbreeding and farmers suffer the consequences.

Artisinal tropical aquaculture in a genetic plunge towards extinction

Artisanal shrimp aquaculture is in a disease-induced crisis of lost production. The immediate cause is biological: rising levels of inbreeding and a strong, positive relationship between inbreeding and disease. The root cause is social: a nexus of human behavior in which breeders protect their intellectual property by generating inbreeding, local hatcheries sell copied, inbred shrimp, and farmers suffer the consequences.
