Temperature and salinity data were collected to characterise the species' environment. Data subsequently integrated with those of other nations' within the ICES framework. Equipment used: GOV trawls, CTD. Additional work included such as MIK sampling undertaken during night-time periods for Clupeoid post-larvae. Servicing of SPAN moorings also undertaken on this survey across selected sites within survey area.
