Phenotypic analysis of the european oyster Ostrea edulis L.: Relationship between length of larval period and postsetting growth rate

Individually tagged oysters ( Ostrea edulis L.) from two year classes were monitored from day of setting to a mean size of 61 and 73 mm. The length of larval period (LLP) was measured as the numbered days from release to setting. In some spawning groups, the LLP was found to be negatively correlated...

Description
Summary:Individually tagged oysters ( Ostrea edulis L.) from two year classes were monitored from day of setting to a mean size of 61 and 73 mm. The length of larval period (LLP) was measured as the numbered days from release to setting. In some spawning groups, the LLP was found to be negatively correlated with the size of individuals during the first season (mean size of 14 to 23 mm). However, in subsequent seasons, the correlations become close to zero and, at last measurement, the effect of LLP had disappeared completely. Although culling of slow-growing larvae will have no impact on improving growth to market size, it may be important in improving the economics of intensive nursery culture.
