Description 
Summary

The specific objectives of MAFCONS are to: (1) Bring together and formalise the relevant ecological theory in order to develop suitable hypotheses related to the mechanisms through which the ecological disturbance of fishing affects the diversity of fish and benthos communities. (2) Collect the relevant data to test these hypotheses, including data on: (a) variation in fishing effort to estimate variation in ecological disturbance. (b) variation in benthic invertebrate productivity and species diversity. (c) variation in groundfish species diversity. (3) Establish the relationships between fishing effort (which will be used to predict ecological disturbance) and the tools used to manage fisheries (at present TACs, but moving towards restriction of effort and closed areas or seasons in some situations).
