DAERA Annual Estuarine Fish Survey 2009

The DAERA estuarine fish survey is an annual assessment of fish communities in seven river estuaries in Northern Ireland. Data is collected primarily for the purposes of reporting to Water Framework Directive (WFD), although a subset of the data is reported to the MERMAN database for inclusion in the Clean Seas Evidence Group (CSEG) work programme.
