  <dc:description xmlns:dc="http://purl.org/dc/elements/1.1/">Objectives
To conduct an acoustic survey to estimate the abundance and distribution of herring in the north western North Sea and north of Scotland between 58&#xBA;30&#x2019;-62&#xBA;N and from the shelf edge to 2&#xBA;E, excluding Faroese waters. In addition acoustic transects will be carried out in Moray Firth to estimate abundance of herring and sprat.
To obtain biological samples for echosounder trace identification using a pelagic trawl.
To obtain samples of herring (and sprat) for biological analysis, including age, length, weight, sex, maturity, ichthyophonus infection and stock identity for herring caught west of 4 &#xBA;W (photos for morphometric stock ID analysis and tissue samples for genetic analysis).
To test feasibility of using GoPro cameras mounted in the net and on a dropframe to further aid in species identification in the echogram scrutiny process.
To obtain hydrographic data for comparison with the horizontal and vertical distribution of herring (and sprat).</dc:description>
