Resumen

This article describes the actors involved in the recommendation of the Peruvian anchoveta catch quota prior to the fishing seasons of each region (north-central and south), as well as the bias associated with it. The data on biomasses, quotas, and landings correspond to the 2000-2022 period, while the recommendations for the total quota correspond to 2019-2022. For the north-central region, Imarpe recommends Produce an exploitation rate lower than or equal to 0.35. This is done through a decision table for four probable oceanographic environment scenarios, considering a remaining biomass to ensure sustainability. The compliance of Peruvian anchoveta catches quotas in the first fishing seasons has been higher than 90 %, while in the second fishing seasons, catches have even been less than 50 %, as in the case of: 2001, 2019, 2010 and 2017. Between 2019 and 2022, Produce opted for the following: i) with a quota lower than that recommended in the decision table (I-2021, II-2020, I-2019) and ii) with a quota higher than that recommended in the biomass of the decision table (I-2022, II-2021, II-2022, II-2019 and I-2020). The observation error is lower (0.10) for the summer surveys and higher (0.15) for the winter-spring (spawning biomass and hydroacoustic surveys).
