Assessing Potential Impacts of Offshore Fish Farming on Small-Scale Fishery in Monastir Bay (Eastern Shore of Tunisia)
Journal Title: Haya: The Saudi Journal of Life Sciences - Year 2018, Vol 3, Issue 3
Abstract
Abstract:The establishment of offshore aquaculture production areas that compete with traditional fishing activities is a potential source of conflict that needs to be assessed in coastal areas. Having little specific data available on the impacts of these farms, we aimed, through the present study, to gather information on this issue, especially regarding Monastir bay, a major zone of aquaculture production in the eastern shore of Tunisia. Hence, we have surveyed fishers’ observations through a questionnaire-based methodology. A total of 78 fishermen were interviewed, in December 2016, in three different ports: Monastir, Sayada and Teboulba. Results revealed that 77 % of local fishing communities complained about the loss of fishing grounds and changes in the quantity and quality of catches. Net damage, caused by dolphin predation, was reported by 31% of fishermen. The most abundant and dominant fish and mollusc species around fish farms, as reported by 30% of inquired fishermen, were Mugil cephalus, Octopus vulgarisand Sardinella aurita, while 15% of fishermen interviewed reported the presence of marine turtles near cage fish farms. The present survey already provides an important data platform that will be useful to decision makers, to adopt appropriate strategies allowing harmonious coexistence between fish farms and fishing activities, in order to ensure ecological sustainability. Keywords: Aquaculture, Coastal fishing, Marine species aggregation, Survey.
