Fertility of the capelin Mallotus villosus in the estuary and the Gulf of Saint-Lawrence in 2003 Fecondite du capelan Mallotus villosus dans lestuaire et le golfe de Saint-Laurent en 2003

, : Fertility of the capelin Mallotus villosus in the estuary and the Gulf of Saint-Lawrence in 2003 Fecondite du capelan Mallotus villosus dans lestuaire et le golfe de Saint-Laurent en 2003. Canadian Technical Report of Fisheries and Aquatic Sciences, 2560: 1-22, VI

A capelin fecundity study was carried out in the Estuary and Gulf of St. Lawrence in 2003. Ovaries were collected at three of the most important fishing locations between 10 May and I July. The fecundity, obtained using the gravimetric method, was evaluated at 18,326 eggs for the ovaries sampled in the Lower St. Lawrence compared to 16,129 eggs and 19,559 eggs for those coming from Sept-Iles and Newfoundland. Linear regressions were used to describe the relationships between fecundity, weight, and fresh length. Slopes of these regressions were not significantly different from one site to another. Histological examination of the ovaries revealed that the development of the vitellogenic or mature oocytes is synchronous. The mean diameter of the vitellogenic oocytes from Lower St. Lawrence capelin was 0.610 mm compared to 0.613 nun and 0.619 mm from Sept-Iles and Newfoundland capelin. A large difference was observed between the frequency distributions of vitellogenic and previtellogenic oocyte diameters. This means that capelin spawning is determinate. We found that capelin fecundity can be calculated rapidly from a relationship between the mean number of oocytes per gram of ovary and the mean oocyte diameter. Fecundities obtained with this relationship are similar to those calculated using the gravimetric method.
