“…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.…”
