3.2.1 How FLR is developed under and supporting EFIMAS

The EFIMAS project aims to develop an operational and generic fisheries management evaluation framework (MEF) that can be used for evaluating different types of management measures, i.e. that allows evaluation of the trade-off between different management objectives when choosing between different management options. In the Technical Annex of the EFIMAS Project Contract [EFIMAS, 2004a] the process of developing the evaluation framework has been described as an iterative, cyclic feed-back process of developing the methodology (between WP3-WP4) and then applying these methods in different case studies (WP4). The overall usefulness of the evaluation framework will be addressed in WP5 - also through a cyclic feed-back process between WP5, WP3 and WP4. The development of the MEF will additionally be based on feed-back from a review of relevant knowledge basis in WP2. Consequently, the general aspects of the evaluation framework are being developed in cooperation between EFIMAS WP3-5 and informed as well by WP2 in order to inform an exploratory, adaptive decision-making process. The analytical tools developed utilise stochastic simulation techniques. These tools simulate the complete fishery management system, including the fish resources and fleets, through data collection, assessment and management, and the response of the system to management.

The evaluation tools are applied to a variety of case studies in order to appraise the biological, social and economic effects of fisheries management measures in the EU. As noted under WP4, these case studies were chosen as they to a large extent reflected the full scope of the management system currently in operation in Europe, as well as widely varying biological, economic, technical and environmental conditions. The proposed simulations also cover the current and potentially alternative management tools that are being considered in European fisheries management. Finally, the case studies represent different types of important EU fisheries.

In practice, there has been a very close link between the development of the management evaluation framework (WP3) and the application in case studies (WP4). The main fisheries management evaluation tool developed by EFIMAS and sister projects is FLR (Fisheries Library in R being an object oriented simulation framework) which is described in detail in the below chapters under WP3. Most of the generic biological FLR objects (FLStock, FLSR, FLXSA, FLSURBA, FLFleet, FLEcon, etc. - see below) have been developed and documented and are operational. Some of those are further developed on in a continous development process under FLR. Biological and technical / economical operating models have been implemented and parameterized in mostly FLR, and from base case studies full scenarios have been applied and completed. Consequently, several economical operating models have been established. This work has been supported through the work of EFIMAS ECONOWS (Economist Workshops)(see below). Full implementation of the economical and fisheries operating models have been achieved as well as the linking of those to the biological operating models.

Consequently, most of the development work has been focussed on generic fisheries and economical FLR objects as well as implementation of those through WP3 and WP4. The economical object FLEcon has been finally established and contains a row of general and case specific equations for the various relevant economic processes. The economist meeting and workshops (ECONOWS) - also with participation of biological OM experts - in Copenhagen January 2007, Lissabon April 2007, and Copenhagen January 2008 (EFIMAS 2008. Final ECONOWS Report) produced a full economic report summarizing the previous economist meetings in Sevilla, London and Nantes (see the EFIMAS Products and Activity List) and also produced generic mathematical equations to be used for different relevant processes in the economical OMs. This has been formulated into R/FLR, and into FLEcon with full documentation.

Because the work has been conducted through the close linkage and cooperation between the development of the generic framework (WP3) and the application in the case studies (WP4) it has been accepted by the EU Commission to merge the case specific application and implementation of MEF under WP3 and WP4 (i.e. to combine EFIMAS Deliverables D3.2 and D4.1 as well as Deliverables D3.4 and D4.2). Both the generic MEF development as well as the case specific application and implementation under EFIMAS has been completed.
