Variabilidad en el tamaño de ovocitos y fecundidad parcial de anchoveta (<i>Engraulis ringens</i>,

Abstract: suMMarY: utilising histological preparations of ovaries from Engraulis ringens females collected in two contrasting spawning habitats along the Chilean coast, we assess the variability in oocyte size and batch fecundity during the peak spawning seasons in three years. the effects of female size (length and weight), batch fecundity and mean sea surface temperature on oocyte size were also examined. results showed larger oocytes and lower batch fecundity in females from the southern area. oocyte volume differenc… Show more

“…Similarly, showed for the Chilean sardine that variations in batch fecundity were not explained by differences in egg size. On the contrary, an inverse relationship between offspring quantity and quality was reported by Leal et al (2009) for the Chilean anchoveta, who observed an inverse latitudinal trend between batch fecundity and oocyte size. Given that both relative batch fecundity and planktonic egg size are conditioned by environmental factors in sardine (see below), large-scale assessments might reveal some degree of interplay between these two factors.…”
