Abstract
    The tryout of a new Irish bottom trawl with a big vertical opening in the region of Mahdia shows that this trawl is very efficient. The comparison of the catches between the Irish trawl and the Tunisian shrimp trawl, shows that the catching efficiency of the Irish trawl is three times better than the catching efficiency of the Tunisian trawl. Also, this study shows that the Irish trawl is more selective than the Tunisian trawl because the catches obtained by the Irish trawl are composed essentially by big fishes. Consequently, the introduction of the Irish trawl in Tunisian fisheries can reduce the problem of catching a big amount of small fish and can protect our marine resources.
