Abstract--Larval growth rates of the anchoveta Engraulis ringens were determined for two periods during the winter spawning season offTalcahuano, central Chile. Because winter is the season of minimum plankton production during the year, we hypothesized that larval growth rates during winter should be constantly low because of decreased larval fish food availability. Our results, however, indicate that 1) mean larval growth rates determined from three growth models in winter (mid-July through mid-September) were as high as in other periods of the year (linear, Gompertz, and von Bertalanffy; 0.47 mm/d, 0.50 mm/d, and 0.48 mm/d, repectively); 2) differences in larval growth ...
