Abstract

Cheilodactylus variegatus "pintadilla" is a species of interest to artisanal fishermen and sports fishermen, the objective of this study was to know the situation of this species in the La Libertad Region in 2020, only focused on commercial fishing. The global sex ratio is adjusted to 1M:1H and in the pattern of the sex ratio to the length the predominance of females is observed. The growth is allometric and the infinite length has been estimated at 39.90 cm, K= 0.48/year with Rn of 0.376, to=-0.56 years. The exploitation rate 0.59 is higher than the optimal level (0.50), however, the impact of recreational fishing on this stock still needs to be evaluated. The vessels dedicated to pintadilla fishing are boats and punts, with the most frequent use of net gills The percentage of extracted juveniles is 43%, which places this hydrobiological resource at risk.
