6. Ghent University Aquaculture R&D Consortium



The Ghent University Aquaculture R&D Consortium brings together 17 research groups from 3 different faculties focusing on various aspects related to aquaculture. Research activities include zootechnology (larviculture), morphology, immunology, genetics, pathology, microbiology (protistology, bacteriology and virology), biochemistry, ecology, marine biology, (human) nutrition, (organic) chemistry and synthesis, and economy. The consortium is managed by the Laboratory of Aquaculture & Artemia Reference Center.

The Laboratory of Aquaculture & Artemia Reference Center has long years of experience with respect to aquatic host-microbe interactions: disease prevention and control, immunology, immunostimulation and priming, virulence gene regulation (including quorum sensing), antivirulence therapy and microbial ecology. Several model systems that allow studying the behaviour of vibrios during infection of a host are operational at the laboratory, including brine shrimp (Artemia franciscana) larvae challenged with V. anguillarum, V. campbellii, V. harveyi or V. parahaemolyticus, sea bass (Dicentrarchus labrax) larvae challenged with V. anguillarum, and blue mussel (Mytilus edulis) larvae challenged with V. anguillarum, V. campbellii or V. splendidus. These organisms can be reared under conventional as well as under (semi-)gnotobiotic conditions.
