Abstract
The objective of this study was to examine the space and environment variables that contributed to the presence of swordfish in the Strait of Messina during the 2003 and 2004 harpoon fishing activity. The relationships between catches per location and environmental factors (current, moon phase and sea surface temperature) were analyzed using a generalized linear model (GLM). The GLM analysis showed differences in CPUE (catch per unit effort) values in terms of swordfish numbers per location over the 2-year period. The central locations of the Strait were found to be teeming with fish; the CPUE was also higher in these areas during the new and rising moon phases.
