The possible of improving productivity in aquaculture by
applying selection and crossbreeding is very good. This is
particularly due to large genetic variance in most of the
economically important traits and to high fecundity in species
of interest. To increase the efficiency of the breeding
program individual selection should be combined with family
selection since some of the traits have low heritability and
since traits like meat quality, survival and age at maturation
are included. It is recommended that breeding stations for
carrying out selection programs are develop. Progeny testing
is of little interest, although both sexes could be tested,
since it increases the generation interval markedly.
