Combining scientific and fishers' knowledge to identify possible roundfish 'Essential Fish Habitats'
Fishers have often complained that standard United Kingdom groundfish survey data do notadequately reflect the grounds targeted by commercial fishers, and hence, scientists tend to make overcautiousestimates of fish abundance. Such criticisms are of particular importance if we are to make acreditabl...

Fishers have often complained that standard United Kingdom groundfish survey data do notadequately reflect the grounds targeted by commercial fishers, and hence, scientists tend to make overcautiousestimates of fish abundance. Such criticisms are of particular importance if we are to make acreditable attempt to classify potential essential fish habitat (EFH) using existing data from groundfishsurveys. Nevertheless, these data sets provide a powerful tool to examine temporal abundance of fishon a large spatial scale. Here, we report a questionnaire-type survey of fishers (20012002) that invitedthem to plot the location of grounds of key importance in the Irish Sea and to comment on key habitatfeatures that might constitute EFH for Atlantic cod Gadus morhua, haddock Melanogrammus aeglefinus,and European whiting Merlangius merlangus.
