The present study evaluated the economic impact of growth overfishing in the industrial fishing of Peruvian anchovy (Engraulis ringens) during the period 2000-2019. The Thompson and Bell (1934) predictive model was used to project the biomass of juveniles captured until they reach the minimum catch size of 12 cm, incorporating conversion factors and prices to estimate the volume and value of fishmeal and oil fish production. The projected biomass was estimated using information on the size composition of the monthly catch, von Bertalanffy growth parameters, natural mortality and length-weight relationship. The production volume was estimated using conversion factors and the production value was estimated using updated prices through the consumer price index. The income not received from the production of fishmeal and oil fish was estimated by subtracting the value of the biomass of the juveniles that reached the minimum catch size of 12 cm and the value of the weight of the juveniles captured. The results show that, during the periods 2001-2005 and 2015-2019, the annual catch of anchovy exceeded the tolerance limit allowed for the extraction of juveniles of 10 %, while, during the period 2006-2014, the extraction of anchovy juveniles did not exceed the tolerance limit. The results indicate captures of 780.7 million juvenile individuals during the 2000-2019 period. These captures represented income not received of 516.7 million USD, equivalent to 1.83 % of the total income received. In addition, a significant positive trend was observed in income not received during the 2010-2019 period (p<0.05). In the sense, the effectiveness of fisheries management measures and the application of other management measures to reduce the capture of juvenile anchoveta should be evaluated and discussed.
