MarGISTM_Shellfish system applications

– Facilitates the prediction of different scenarios, which could influence the nature and /or scale of shellfish aquaculture activity in a bay area.

– Provides decision support to the industry with respect the location and optimal size of shellfish aquaculture sites.Promotes sustainable aquaculture by identifying bays that are– Promotes sustainable aquaculture by identifying bays that are currently under-utilised with respect to shellfish aquaculture.

– Promote sustainable aquaculture by identifying areas where carrying capacity has been exceeded.

– Provides an information base and liaison facility for industry


M GIS™ i i i f i dl l h• MarGIS™ is an exciting, user-friendly management tool that integrates existing numerical models into a GIS framework. It has been specifically designed for use by non-modellers to efficiently undertake water quality model simulations, execute model runs, and visualise and report on simulation results within a single environment.

• MarGIS™ has been adopted by the Northwest Region of the United Ki d E i t A ‘b t ti ’ i f lfilli th iKingdom Environment Agency as ‘best practice’ in fulfilling their

obligations under the EU Habitats Directive
