The foundation of quantitative genetics theory was developed during
the last century and facilitated many successful breeding programs
for cultivated plants and t- restrial livestock. The results have
been almost universally impressive, and today nearly all
agricultural production utilises genetically improved seed and
animals. The aquaculture industry can learn a great deal from these
experiences, because the basic theory behind selective breeding is
the same for all species. The ?rst published selection experiments
in aquaculture started in 1920 s to improve disease resistance in
?sh, but it was not before the 1970 s that the ?rst family based
breeding program was initiated for Atlantic salmon in Norway by
AKVAFORSK. Unfortunately, the subsequent implementation of
selective breeding on a wider scale in aquaculture has been slow,
and despite the dramatic gains that have been demonstrated in a
number of species, less than 10% of world aquaculture production is
currently based on improved stocks. For the long-term
sustainability of aquaculture production, there is an urgent need
to develop and implement e- cient breeding programs for all species
under commercial production. The ability for aquaculture to
successfully meet the demands of an ever increasing human p-
ulation, will rely on genetically improved stocks that utilise
feed, water and land resources in an ef?cient way. Technological
advances like genome sequences of aquaculture species, and advanced
molecular methods means that there are new and exciting prospects
for building on these well-established methods into the future.
