PREGUNTAS FUNDAMENTALES

RETROSPECTIVE ANALYSIS Includes recovery and review of historical data, mainly of foreign fleets (Soviet amd Cuban trawling Fleeet).

Questions:

• 1. ¿What about spatial and temporal variability of jack mackerel

distributión on peruvian sea? (mainly juveniles and adults)

• 2. ¿ What about decadal changes affect jack mackerel population?
