This research was conducted during the period from June to November 2010 in the North of Tunisia (Kelibia). The schools of dolphins realize a negative interference effect when it attacks in the fish surrounded by purse seine, or on pursing. This damages the fishing nets and reduces the catches. Fishing operations carried without pingers shows a mean of attacks cases more important then the boats with Pingers. The technical efficiency is about 19, 85%. The technical efficiency is doubtful.
