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.

Abstract
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.File in questo prodotto:
