There are several factors that cause variability within a fishery (e.g. biological and environmental conditions, management rules, vessel characteristics, etc) leading fishermen to implement different strategies. The goal of this study was to characterize the fishing operations of the Peruvian anchovy industrial fishery by classifying them into different groups which represented particular fishing strategies. To this end, more than 15000 fishing operations documented by an on-board observer program (i.e. Logbook Program- Programa Bitácoras de Pesca o PBP) over 2005-2014 were analyzed. Each fishing operation was describe according to its geographic location, distance to the coast, distance to the shelf break, duration, catch and efficiency of the fishing operation. With the combination of two multivariate techniques (i.e. Principal Component Analysis and Clustering), four groups were identified. These were mainly associated with different environmental conditions, fleet segments and management measures. Identifying these groups and their relationship to the above factors will allow the recognition of changes in fishing strategies in the face of changes in environmental conditions (i.e. El Niño/La Niña events), or in the composition of the fleet (i.e. increase in the proportion of wooden vessels or vessels in the south) and this in turn will provide better tools for good management of the fishery.
