As a result, the growth parameters of Mya arenaria were determined for a large part of mollusc life cycle (from 7 years at sites 3 and 4 to 25 years at site 1). Both individual and group (average) growth characteristics of the 1988 and the 1999 generations were used to analyse the variability of Mya growth rate at the studied beds.

2014-01-01 · 1. Introduction. In the Baltic Sea and its estuaries, water salinity is one of the key factors determining the occurrence, distribution, and abundance of species via its effect on the functional ecology of aquatic animals (e.g. growth rate, life cycles, production, and energy flows) (Kullenberg, 1991, Gogina and Zettler, 2010, Ojaveer et al., 2010, Bleich et al., 2011).
