Abstract
SEFABAR is a EU-sponsored thematic network that combines the expertise of over
40 scientists and business representatives in animal breeding, reproduction
and socio-economics from all over Europe. The working group on aquaculture contains
representatives from Belgium (Leuven University), France (INRA, IFREMER, SYSAAF),
Great Britain (Stirling), Greece (Selonda), Norway (Akvaforsk, Aquagen), the
Netherlands (Wageningen University), Ireland (Nutreco) Spain (CSIC) and the
European Aquaculture Society. SEFABAR aims at finding sustainable, economically
sound and accepted breeding scenarios for major European farm animal species,
including fish. The three-year project was started in 2000.
The common principle for SEFABAR was defined as "Genetics for Future use".
The main elements are quality (end-product, safety, healthiness to consumers),
diversity (bio-diversity, product diversification to local markets, adaptation
and robustness), acceptability (ethical aspects and animal welfare) and economic
viability in the short and long term.
In aquaculture, the main priorities are economic viability (high costs of fish
production), minimization of environmental impact (escapes and possible interbreeding
of domesticated and wild animals) and maintenance of animal integrity (normal
physiological and reproductive functions). The main option is to redefine breeding
goals for fish into a wider perspective by a) producing animals with a economic
productive life without giving signs of disturbed health and welfare in a specific
environment and b) by optimizing input/output and feed efficiency with sustainable
feed resources. In fish, biotechnologies derived from plant breeding offer exciting
possibilities, but before they are implemented, and extended to new traits,
good selection criteria have to be defined. Breeding schemes need to cover the
wide range of production environments used in aquaculture, to be able to select
animals that perform well in a wide range of production circumstances, and to
select animals that are best adapted to specific farming environments.
