Management Strategy Evaluation toolkit for Ecopath with Ecosim (model output and technical report)
Description
This dataset consists of output from a computer model that predicts responses
of 69 functional groups from plankton to whales to changing fishing pressure.
Scenarios are run using the newly built plug-in (see report) that allows for
an assessment of the effect of model parameter uncertainty. The base model is
the ICES key-run of EwE for the North Sea described here
`http://data.cefas.co.uk/#/View/2847`_. Format of the data: Zipped csv files
covering the hindcast period 1991-2013 (inclusive) with 20 year forecasts.
Output includes annual average values for the whole North Sea: For both
functional groups and fishing fleets: landings (tonnage and value, £),
discards (tonnage),for functional groups only: biomass (tonnage) and fishing
mortality (split by landings and discards), for fishing fleets only: fishing
effort relative to 1990. Also identified are 'choke species' that lead to
closure of fisheries. The report (pdf) describes the development of a tool for
assessing the effect of model parameter uncertainty on the performance of
management options simulated using an ecosystem model. It provides the
rationale, description of methods and algorithms, and a step-by-step guide for
users of the tool. While the interface of the tool is designed to be user
friendly, the setup of input files and its application requires a thorough
understanding of the parameterisation of Ecopath models, advanced experience
with Ecosim and understanding of Management Strategy Evaluation procedures.
