| Abstract |
Gametogenesis in two populations of Mytilus edulis was studied by measuring (with stereological techniques) the relative volume fractions of vesicular connective tissue cells, adipogranular cells (these two cell types comprising the nutrient store of the mantle) developing and ripe gametes. In one population the expected seasonal cycle, of nutrient storage in the summer, gametogenesis in the autumn and winter and spawning in the spring, was evident. In another population, however, both gametogenesis and the development of storage reserve tissue occurred concurrently in the summer, followed by a second spawning in the late summer or autumn. In two years characterized by high air temperatures during the summer, mussels in this population showed disturbance to the gametogenetic rhythm. |
