Topic 3: INTEGRATED COASTAL ZONE MANAGEMENT<br />
collapse of pluviometric levels during summer. Prevailing and strongest winds are<br />
those from I and IV quadrants. The superficial sea temperature has a regular seasonal<br />
cyclical trend, typical of Sicilian coastal waters, with increasing temperatures from<br />
June to September. The geomorphological and bionomical surveys revealed high<br />
heterogeneity of coastal bottoms, for the co-occurrence of hard bottoms, soft (mainly<br />
silt-clay) bottoms and wide zones colonised by Posidonia oceanica (L.) Delile which<br />
generally resulted in good state of health; benthic communities appeared qualitatively<br />
and quantitatively poor, due to high sedimentation (Perzia et al., 2010). The main<br />
human activities are small-scale fishery and tourism. The artisanal fleet (26 total active<br />
vessels) resulted in high contraction, compared with that (66 vessels) recorded in 1992.<br />
Trammel net was the most used gear during the whole study period; entangling net for<br />
capture of European hake (Merluccius merluccius) and drifting longline for capture<br />
swordfish (Xiphias gladius) are used seasonally; seine net for “bianchetto” (larvae of<br />
clupeiforms) is also a seasonal gear, according to regional authorizations; all the other<br />
gears (bottom longline, monofilament, purse seine) are very rarely utilized (Falautano<br />
et al., 2008). The principal target species of Sciacca artisanal fishery resulted Palinurus<br />
elephas, Diplodus spp, Sepia officinalis, M. merluccius (adult stage) and X. gladius.<br />
The data analysis by GIS revealed that the fishing areas mainly exploited by artisanal<br />
fishermen are displaced near the coast. The socio-demographic analysis showed an<br />
encouraging percentage of fishermen’s sons working with their own fathers and willing<br />
to go in for the paternal profession (Falautano et al., 2008). The analysis of cultural<br />
heritage showed the disappearance of some fishing metiers and the permanence of<br />
some cultural traditions linked to local fishery such as gastronomic traditions, folk<br />
songs, poetry, legends and architectonical elements typical of fishing villages<br />
(Falautano et al., 2008).<br />
Identifying phase. The environmental limits are ascribable to the occurrence of urban<br />
wastes, conspicuous coastal building and rubbish dispersed on the beaches and<br />
deposited on coastal bottoms which cause ecological alteration and may conflict with<br />
fishery activities. The factors limiting and impoverishing small-scale fishery in the<br />
study area are referable to the sector structure and to the use of resources and space.<br />
The artisanal vessels resulted old and poorly modernized, to the detriment of safety on<br />
board and product quality. Their limited engine power obliges most fishermen to<br />
operate only near the coast. Another structural limit is the inadequacy and paucity of<br />
harbour infrastructures supporting artisanal fishery: there are no reserved mooring<br />
areas for fishing vessels which are sparsely displaced in harbour areas at unhealthy<br />
sanitary conditions, nor fishing gear storages. The use of resources is limited by the<br />
well developed and uncontrolled recreational fishery, which operates in unfair<br />
competition with the artisanal fishery; also industrial fishery competes with artisanal<br />
fishery, illegally exploiting coastal resources, as evidenced by the traces of trawling<br />
observed by side scan sonar (Perzia et al., 2010). Terrritorial limits are represented by<br />
flourished nautical tourism which competes with artisanal fishery for spaces<br />
exploitation at sea and in the harbour.<br />
Proposal phase. The principal intervention activities to be actuated for overcoming the<br />
identified limits are: to promote behaviours and actions aiming at safeguarding the<br />
environment; to provide incentives for the modernization of artisanal vessels in order<br />
to improve safety and life quality onboard and product quality, also favouring fishing<br />
offshore; to improve harbour infrastructures supporting artisanal fishery; to regulate<br />
