--- Some biological, population, and fisheries indicators of “hairy crab” Cancer setosus (Molina, 1782) were determined in the area of Callao with the purpose of providing some technical elements for fisheries management. First, 4 553 specimens from Callao’s artisanal fishery area were analyzed during the period 2006 to 2008. The observed sexual proportion differs from 1:1, which is the most frequent measure between male specimens since a major pressure of fishing is exercised over them due to their larger size and better performance according to their weight. Along with that, the relationship between length and weight was isometric in both sexes; defined as Peso total = 0,0001 * AC^3,10 in males, and Peso total: 0.0006 * AC^2,77 in females. Besides, morphometric maturity for males was estimated as 120.5 mm AC. The growth also showed some differences between both sexes, males reach larger sizes (L∞=204.1) and grow more rapidly (K=0.56), while females are smaller size (L∞=194.1) and lower growth rate (K=0.52). The capture and effort values were higher during summer and autumn; there was no direct relationship between captures and environmental variables but with the effort applied in extractive activities. As a result from the obtained and analyzed information, it can be said that despite the strong pressure over fishing, the “hairy crab” population could stand by itself the rhythm of fishery during the study period. Moreover, to be more conclusive, is important and necessary to make effective more researches which allow us to establish the optimal capture and effort levels for a sustainable activity.
