Abstract
The possibility for a trade-off between age-specific residual reproductive value (RRV) and reproductive effort (RE) was investigated. Different ways of estimating RE did not affect conclusions which were: a) there is no clear trade-off between RRV and RE until the scallop has reached an age of about 13 years, i.e. after a reproductive life of about eight years; b) the larva of C. islandica is more important as a means of dispersal than as a means of maintaining the parent population.Keywords
