INFORMATION FOR DEVELOPING SELECTIVE BREEDING PROGRAMMES
A compilation of information about oyster immune system is provided through three different approaches: (1) phenotypical
(expressed characters), (2) genetic and (3) field testing, based in the performance of several hatchery-produced families from
different populations. This will be valuable information needed for developing future selective breeding programmes.
This information package includes:
Description of the origin of oyster immune system failure to impede B.ostreae infection and of the differences in
bonamiosis susceptibility between different oyster stocks.
Identified phenotypical markers that can be used in selective breeding programmes for bonamiosis tolerance
Genetic information (list of candidate genes) directly related with immunity to bonamiosis
Identification and characterization of best performing families within stocks, which could be a source of broodstock for
developing selective breeding programmes.

INNOVATION
KEY BENEFITS
The information obtained will facilitate
the identification and validation of
potential resistance in stocks, which
could be applied for developing future
selective breeding programmes or for
improving on-going ones.
Traditionally, tolerant strains have been
obtained from a selection of survivors or
best performers. Despite being effective,
this is much slower and less efficient than
implementing a marker assisted selective
breeding programme based on the
biotechnological tools provided by the
OYSTERECOVER project
Possibility of implementing selective
breeding programmes adapted to
different environmental conditions, to
mitigate the effects of bonamiosis in the
short term
Despite the important progress
that can be derived from the application
of these methodologies, some technical
problems in the hatchery production may hinder
the successful development of selective
breeding programmes.
Indeed, O. edulis seed production in hatchery
facilities has been often reported to be erratic, with
sudden and unexplained larval and postmetamorphosis mortalities, and this is still an
important constraint that should be tackled
in the short term. Only then, these results
could be fully exploited and yield
all its potential impact
to the market
