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?

BIOLOGICAL PROCESS Includes researches of biological process who are important for changes on abundance. Questions: 1. ¿What are the spawning areas on peruvian sea? 2. ¿What are the main factors who affect success recruitment? 3. ¿ What are its feeding preferences? 4.- ¿There is changes on growth parameters?

PREGUNTAS FUNDAMENTALES RESEARCH ABOUT AVAILABILITY OF RESOURCES To know abundance of jack mackerel using direct and indirect assesments. Questions: 1.- ¿What about biomass of jack mackerel inshore and ofshore 200 miles in front of peruvian coast? 2.- ¿Is possible to get a relative abundance index for jack mackerel ? 3.- ¿Is possible to identify unit stocks of jack mackerel on peruvian sea, using isotopic analyses? 4.- ¿What is the spatial dynamics of fishing areas?

PREGUNTAS FUNDAMENTALES BIOECONOMIC RESEARCH Try to correlate economic, biological and social aspects on jack mackerel fisheries. Questions: 1.- ¿What is the optimal economic yield? 2.- ¿Wich is better: to use jack mackerel on national market or 2.- ¿Wich is better: to use jack mackerel on national market or international market?
