Synthesis of New Knowledge about Determinism of Pacific Oysters (Crassostrea gigas) Larval Recruitment in the Mediterranean Thau Lagoon

摘要

Recent discoveries of Japanese oysters spat field in Thau lagoon open up interesting prospects for research in nanotidal system. The analyses of collected environmental parameters allow to better characterize favorable sites and periods. Spat collecting in Thau lagoon presents high spatial, small-time scale and inter-annual variabilities induced by hydrodynamic, predation, competition and trophic resource variability. These first results give highlights about explicative factors of ecological variations of the natural oyster recruitment in Thau lagoon.
