Özet:

 

In this study, an economic analysis of the effect of pingers as "anti-depredation" devices on artisanal fisheries and  dolphin depredation was performed. By comparing the data of the gross Profit Per Unit Effort (PPUE) over 29 fishing days  for two identical nets (900-m long, one was equipped with pingers, and the other did not have pingers), was assessed the  following: the different production trends of the nets (Advantage of Production, AP) and the Return Of Investment (ROI) for  the purchase of the pingers. Considering the difference in the PPUE values of the two nets, the frequency of the dolphin  interaction, and the effort of fishing activities, was assessed the one-year economic losses (ED) due to dolphin depredation.  Moreover, was assessed the economic damage caused by the destroyed area of the nets.  The AP over 29 fishing days for the use of the pinger net with respect to the control net is 25.7 Euros for each 50 m of  net. The ROI for the initial investment of the pingers (4 pinger = 800 Euro) is 50 fishing days, and the ED is 1400 Euros. The  damages suffered by the control and the pinger nets were 33 m2 (90 Euros) and 22 m2 (91 Euros), respectively.  The analysis of the results demonstrates that the critical factors that determine the success of the pinger technology  could be represented by the return of investment (ROI) and the use of the economic incentives provided by the European  Fisheries Fund (EFF). 	 	 		 .
