Gonad development and fecundity of whitefish, Coregonus lavaretus (L. 1758) from the Pomeranian Bay
The Pomeranian Bay whitefish migrate to the Szczecin Lagoon to spawn. Gonads begin to develop strongly a month before spawning.

description | The Pomeranian Bay whitefish migrate to the Szczecin Lagoon to spawn. Gonads begin to develop strongly a month before spawning. After spawning in late November-early December, gonad development is very slow; the gonads do not gain weight until the end of May next year. The absolute fecundity was found to range from 23.650 to 131.418 eggs. The absolute fecundity was observed to increase considerably with fish length, age and weight. The average relative fecundity was 45.721 eggs per kg body weight (including viscera). |
