It is necessary to establish breeding programs for the species used in aquaculture. However, until such programs have been established and start producing superior strains, these species will be under widespread, intensive culture. Unless the propaga

Genetic differences among natural populations of the blue mussel (Mytilus edulis) appear to have implications for commercial exploitation of the species. Growth and mortality patterns in transplanted versus resident wild stocks presented here verify

One of the potential sources of genetic variation to be used by the breeder working in aquaculture lies in the heterogeneity of natural populations of the species to be cultured. Work on many species, not necessarily aquatic or marine, has shown that

The Chilean oyster, Ostrea chilensis Philippi, shows high phenotypic variability for growth rate within populations. In order to determine if the serial correlation of growth rate in oysters is positive, the correlation between shell height and live

Three shell-shape parameters of Littorina saxatilis were measured and found to vary in a regular pattern with distance up an estuary. The translation rate of the shell increased, the rate of whorl expansion decreased and the circularity of the apertu

Oysters, Crassostrea virginica (Gemlin), were taken from a low- and an intermediate-salinity habitat. Males from each population were crossed with females from both populations and the offspring were raised at three salinities. Observations on surviv

Through a series of factorial matings, it has been determined that in one population of the mussel, Mytilus edulis (L), there is some additive genetic variance for larval growth rate, but the predominant genetic component is nonadditive. In two separ

Adult Crassostrea virginica were obtained from 4 populations and spawned in the laboratory. The larvae from the within-population crosses and the hybrid crosses were raised at 4 salinities. There were no significant differences in survival of the lar

The heritability of oyster (Crassostrea virginica) larval growth rate was estimated to be in the range of 0.25 to 0.50 and a significant part of this genetic variation is of the additive type. Larval growth rate and spat growth rate were found to be
