Mortality and biological performances of half-grown Crassostrea gigas were studied from spring 2000 to autumn 2001 at six instrumented stations located in two areas (Gefosse and Grandcamp) of
the Bay of Veys (Normandy). Shell and meat growth, condition indexes and a macroscopic maturity index were determined on oysters
deployed at the six stations in order to assess spatial variability in the influence of environmental conditions. In addition,
histological and biochemical analyses were performed in order to determine the sex and establish the reproductive cycle (at
all six sites) and the biochemical composition (at four stations). The data set including monthly mean temperatures and data
provided by examination of 2,837 oysters were analysed by Principal Component Analysis and a Hierarchical Ascending Clustering
which resulted in the formation of four clusters. The highest station on the shoreline belonged to a cluster characterized
notably by low total weight due to a short immersion/feeding period, whereas all other stations belonged to another single
cluster. Nevertheless, various biological differences were found between these stations, e.g. the reproductive cycle was generally
synchronized throughout the bay but some differences relative to spawning occurrence were observed. In 2000, oyster mortality
was higher at Gefosse than at Grandcamp, the latter being a more marine area. In 2001, oyster mortalities were significantly
higher and all stations were strongly affected. In the Bay of Veys, oyster biological performances and mortality thus showed
spatio-temporal variations which were worthy to be discussed. 相似文献
