Oil for Fish: An Energy Return on Investment Analysis of Selected European Union Fishing Fleets 5
Guillen, Jordi; Cheilari, Anna; Damalas, Dimitrios; Barbas, Thomas.
World food production has increased substantially in the past century, thanks mostly to the increase in the use of oil as input in the production processes. This growing use of fossil fuels has negative effects, both on the environment and the production costs. Fishing is a fuel consuming food production activity, and its energy efficiency performance has worsened over time. World-wide fisheries are also suffering from overexploitation, which contributes to the poor efficiency performance, adding more pressure and criticism on this economic activity. In this paper we analyzed the energy efficiency performance of more than 20,000 European Union (EU) fishing vessels for the period 2002-2008, using the edible energy return on investment (EROI) indicator. The...

The efficiency of using remote sensing for fisheries enforcement:Application to the Mediterranean bluefin tuna fishery 5
Cicuendez Perez, Juan; Alvarez, Marlene Alvarez; Heikkonen, Jukka; Guillen Garcia, Jordi; Barbas, Thomas.
This paper analyzes the impact of applying vessel detection technology using satellite images (vessel detection system, VDS) to complement air patrols for fisheries enforcement and control. Due to limited fisheries enforcement budgets there is the need to allocate costs efficiently among competing control tools. This paper focuses on assessing the benefits of using VDS jointly with VMS (vessel monitoring system) and air patrol surveillance to improve effectiveness of controls. A statistical model to estimate the number of inspections was developed and was used with enforcement costs data as reported by a number of EU countries. The result of applying VDS in fisheries enforcement is presented in one of the most demanding fisheries enforcement contexts: the...
