	abstract = {Fisheries management in the Mediterranean is planned on the basis of fishing effort allocation, gear technical characteristics and minimum landing sizes (MLSs), the latter being a measure recently updated in the EU Mediterranean fisheries policy. Very few elements on the evaluation of the MLS in regard to the catch and landings of the small-scale fisheries in the Mediterranean exist and this is due to both the great heterogeneity of the sector and the lack of systematic monitoring. The catch length composition of five species (Merluccius merluccius, Diplodus annularis, Mullus barbatus, Sepia officinalis and Squilla mantis) from a yearly record of small-scale fishing operations in the Patraikos Gulf(w. Greece, e. Mediterranean) was associated with temporal (season), spatial (depth of fishing, substrate type) and fishery (metier) characteristics by means of general linear models. Smaller individuals appeared in the catch in autumn for all five species indicating this season as suitable if a seasonal fishery Closure was established. When length was found to be significantly different between different metiers this was either due to smaller mesh sizes (M. barbatus) or due to gear type (M. merluccius). For all species except S. officinalis, depth significantly affected length of individuals in the catch providing in the case of M. merluccius a clear association of bigger individuals with deeper fishing grounds. Substrate types also affected the length for the species D. annularis, M. barbatus. In relation to MLSs, the sizes of Mullus surmuletus and Scomber japonicus were fully legal, M. merluccius, M. barbatus, Solea vulgaris, Trachurus mediterraneus, Pagellus erythrinus had higher than 80\% of the catch over MLS, while D. annularis, Diplodus sargus, Sparus aurata and Pagellus acarne had high fractions of the total catch below MLS. The metiers where undersized individuals appear were identified. Further management implications of the findings are discussed taking into account the current management scheme and the discarding practices in the area. (c) 2008 Elsevier B.V. All rights reserved.},
