9 Due to its widespread geographic distribution, redbait has been reported as bycatch in
23 target fisheries over the last five fishing years. For the fishing years 2002/03 –

taken by the method of mid-water trawl. The following table summarises the total
catch distribution by FMA for the fishing years 2002/03 – 2006/07.
