A European oyster population (Ostrea edulis) was recently discovered off the Eastern coast of Canada. The occurrence of this population led various aquaculture stakeholders to consider this species commercially. The aim of this study is to determine the best time to collect the European oyster larvae to maximize their collection. Gonad observations and plankton tows were carried out in 2005 and 2006 to estimate the time of settlement. Nine days after the first free-swimming larvae were observed, Chinese hat collectors were suspended in the water column every three days at two sites. The collectors were removed from the water after a mean streaming duration of 35 days. Spat were thereafter numbered on each collector. The spawning period lasted from mid-July to the end of August in 2005 and from mid-July to the beginning of August in 2006. Temperature was approximately 18°C during that time. The major peaks of free-swimming larvae were observed at the beginning of August (43,276 larvae m−3) in 2005... |
