Description du projet
Améliorer les connaissances dans le domaine de l’ostréiculture
L’expansion rapide de l’aquaculture des bivalves marins dans le monde accroît la demande de production d’embryons d’huîtres en écloserie. Le manque de synchronisation physiologique des individus freine l’augmentation de la production. Le projet NEUROSHELL, financé par l’UE, améliorera le contrôle environnemental, neuroendocrinien et endocrinien des phases de production des bivalves, dans le but de promouvoir la production d’huîtres en écloserie et la science. Ce projet multidisciplinaire et intersectoriel mettra en œuvre une méthode des rythmes quotidiens en étudiant l’incidence des cycles environnementaux quotidiens sur la reproduction et la métamorphose des larves en naissains. En outre, il produira un profil de facteurs neuroendocriniens et endocriniens ciblés à des stades déterminés.
Objectif
The rapid worldwide expansion of marine bivalve aquaculture has lead to a growing demand for hatchery production of seed. Increase in this production has however been hampered by a lack of physiological synchrony of individuals, with difficulties in 1) conditioning of broodstock and predicting when they will spawn, 2) metamorphosis of larvae into spat. The overall research objective of Neuroshell is to advance knowledge on the environmental, neuroendocrine and endocrine control of these key stages in bivalves. This will be done through a daily rhythms approach, by investigating the effect of daily environmental cycles on reproduction (sub-project 1) and metamorphosis (sub-project 2), and generating a profile of target neuroendocrine/endocrine factors at given stages under these conditions. Then determining whether these factors too exhibit daily rhythmicity. Work will be performed on the European oyster, Ostrea edulis, through in vivo experiments. Neuroshell is multidisciplinary and intersectoral, combining physiological, biochemical and molecular techniques with shellfish aquaculture and industry integration. It also includes a secondment in Spain. Transfer of knowledge and comprehensive training of the researcher are key elements of the action. The core focus of the researcher to date has been on reproductive neuroendocrinology and physiology in fish species for commercial aquaculture. To broaden her research scope dramatically, the project has been developed with the Scottish Association of Marine Science UK (host), to enable her to gain knowledge, skills, competencies, experience and contacts in an entirely new group of species of major commercial importance. Overall, results have the potential capacity to advance hatchery production of marine bivalves and fundamental science, and promote the researcher to a level of professional maturity and independence. Ultimately contributing to the excellence and competitiveness of EU aquaculture research and industry.
