Abstract :
Occurrence of diseases caused by bacteria
during larval culture is still one of the major constraints
in aquaculture. Understanding the host-microbe
interactions is certainly relevant to develop disease
control systems for the aquaculture industry. Therefore,
obtaining test animals free from microorganisms (germfree or axenic) is necessary, as the presence of naturally
occurring microorganisms in the host may lead to false
conclusions. The aim of this study is to obtain axenic
blue mussel (Mytilus edulis) embryo using different
disinfectants. The efficacy of chemicals in reducing the
bacterial load associated with mussel eggs and embryos
is tested, as well as the resistance of the eggs to these
chemicals. For that purpose, fertilized eggs are exposed
to different chemicals at different concentrations. The
disinfectants tested include hydrogen peroxide,
chlorhexidine, and Sanocare HC. All disinfectants are
found to be detrimental for the mussel embryo.
