Abstract
    In this study we present the length frequency distributions of Boopsboops, Mullus barbatus, Scomber japonicus, Spicara smaris and Trachurus mediterraneus caught with different gears (trawls, purse-seines, beach-seines, gill nets, trammel nets and longlines) in Cyclades during 1995-2000. Trawls generally caught the smallest sizes for four out of the five species studied (i.e. B.boops, M. barbatus, S. smaris and T. mediterraneus) and purse-seines caught individuals with intermediate sizes between those caught with trawls and small-scale gears. For S. japonicus, gill nets caught smaller individuals than those caught with purse-seines and trammel nets. The same general pattern was also observed comparing the seasonal length frequencies of the three most abundant species (i.e. B. boops, T. mediterraneus and S. smaris).Generally, trawls caught immature individuals when compared to small-scale gears and the vast majority of the individuals caught by all gears (with the exception of trammel nets for M. barbatus) was smaller than the optimum exploitation size, indicating that the gears examined are not appropriate for the sustainable exploitation of these resources.
