Growth parameters were estimated, using the ELEFAN 1 method [program] of D. Pauly and N. David, from length-frequency data covering the years 1953 to 1982 and pertaining to the northern central stock (4 to 14 degrees South) of the Peruvian anchoveta (Engraulis ringens) and, for larvae and young juveniles, from daily otolith rings. Growth was found to oscillate seasonally with an annual minimum in August when temperatures are usually lowest. The dynamics of "condition" and fat content are discussed with emphasis to their relation to water temperature. A marked increase in the 30-year period covered of anchoveta maximum length and growth performance is documented along with a simulation model used to identify some density-dependent factors capable of explaining the changes in growth that have occurred.
