Exploitation de la Coryphène Coryphaena hippurus sur les côtes Tunisiennes.

Abstract

The results are given of a study of the dolphinfish Coryphaena hippurus fishery production in coastal waters of Tunisia; catches were caught during a survey which lasted 3-4 months. Spatio-temporal fluctuations of the production were analyzed with respect to physico-chemical parameters (temperature and salinity) and exploitation data (recording of contributions, increase of landing sites). Details are given of the catching techniques using fish aggregating devices. The total size at recruitment was estimated at 15 cm. The average sizes were determined throughout the duration of the survey.
