Description
From observations gathered on grilse populations sampled during the fishing period (March -mid-June) or after the fishing season, the authors noted: a strong heterogeneity and length, the mean value of which increase from May to December, a sex-ratio not different from 1 male for 1 female, a high relative fecundity superior to those of spring salmon population sampled. The comparison between fish of local and foreign origins did not allow to observe significant differences between the biological characteristics studied (weight, length, sex-ratio and fecundity).
