A pool of Italian and Tunisian research bodies has started a yearly joint project on monitoring cetacean in the Region between Sicily and Tunisia. In order to: systematically survey regularly the region throughout the years also in high sea areas; reduce reduces spatial heterogeneity; and to make more efficient the use of the budget resources the project, co-financed from ACCOBAMS, uses regular passengers ferries as platform of observations. http://itucre.blogspot.it/ Due to high productive values, the region between Sicily and Tunisia is considered one of the potential wintering grounds for fin whale. The area is also considered a critical habitat for cetacean species due to important anthropogenic pressures such as fishing, aquaculture, maritime traffic, oil and gas industry, communication cables and construction of wind-mill farms. Despite this, no systematic monitoring study has never been undertaken so far. In order to start a systematic cetacean monitoring of the area, a partnership of Tunisian and Italian research bodies participated with success to the ACCOBAMS 2012 open call for “Monitoring, research, training and projects relating to the conservation of Cetaceans”. Main aim of the project was capacity building issues and, to reach this goal, a partnership within the scientific international network that monitors cetacean using ferries as platforms of observation was built. Moreover, two ferry companies were involved in the project allowing to monitor the area among Tunisia, Sicily and Sardinia. Collected data will allow to: assess cetacean presence and distribution in this poorly surveyed area; investigate seasonal trends in cetacean presence and distribution (sighting will be shared on OBIS Sea Map); investigate fin whale migration patterns. In addition, the project will contribute to assess the quantity of events of collision risks. Networking with the other partners that use the same monitoring protocol is an important added value that will allow a synoptic view of cetacean in the Western Mediterranean Sea Region. Overall, the project goal is also to enact policies, between Tunisia and Italy, so to strengthen the cooperation and dialogue between peoples through the sectors of scientific research, culture and friendship
