Resumo: | Fishing power analysis leads to determine a typology of fleet which depends on target species. Three factors are examined : port of origin, engine power and type of trawl. Specific abundance index analysis leads to determine a diagram of principal stages of vital cycle : juvenile, reproductive adult and recovery adult. Then calculs are made in value for all species combined : we obtain thus an economical index by location and season.
