Quelques résultats concernant les travaux en cours sur la fécondité en lots du maquereau bleu (Scomber scombrus L.)
By F. Grégoire; C. Lévesque
Abstract
Batch fecundity for the mackerel in the Gulf of St. Lawrence has been estimated in 1992 and 1993 at 69.05 and 50.80 eggs per gram of female. These results are similar to some values calculated for the mackerel in Europe. No value has been calculated in 1994 because most of the gonads didn't contain hydrated oocytes. Besides annual variations, it seems that batch fecundity shows also spatial variability. The results obtained in this study are preliminary and could be improved after an histological exam of the gonads.
