Temperature effects on the anchoveta Engraulis ringens egg development: do latitudinal differences occur?
We assessed differences in the development rates among anchoveta, E. ringens populations from the extremes of its range under different temperatures. Time to hatch decreased with increasing temperature but there was no difference in the temperature–development time relationship between eggs from different localities. These results and observations of hatching success differences between populations at lower temperatures support the hypothesis that interpopulation differences in the earlier life stages occur along the distribution range of anchoveta, although the current genetic evidence suggests substantial gene flow between localities.
