the time series of landing per unit of effort of some elasmobranch species/category by the Porto S. Stefano and the Viareggio bottom trawls fleets were analyzed by means of Min/Max Auto-correlation factor Analysis. This approach was useful to highlight the increasing trend of such species during the investigated period (1991-2008). the trends were positively affected by the reduction of fishing effort in both Porto S. stefano and Viareggio trawl fleets. the effects of the environmental variables were significant as well.
