The mean potential fecundity in S. norvegicus was estimated to be 123,300 oocytes and relative fe cundity averaged 116 oocytes g –1 . Mean potential fecundity in S. mentella was 50,013 oocytes and relative fecundity was 64 oocytes g –1 . Strong fecundity down-regulation (50% on average) was observe d during oocyte devel opment estimated from September to November, when oocyt es reached the advanced stage of vitellogenesis. T his result implies th at fecundity can only be comparable between individuals pre senting the same stage of oocyte develop ment. However, the development ra tes differed between species a nd between stocks, and therefore the same s tage is reached at a different time of the year. Fecundity varie d significantly with female we ight and length, while condition had little influe nce on fecundity variation. 2015 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48039202003 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.2 Vol.41
