Workshop on methods to develop a swept-area based effort index

A workshop to analyse trawl data and develop a new marine indicator

​​The workshop will look into establishing an effort estimate based in trawl swept-area, applicable for all trawl surveys across ICES countries and ecoregions. The data from these surveys is stored in ICES online database of trawl surveys (DATRAS). This new effort index will ideally reduce biases in calculations resulting from other effort measures based on variables such as types of fishing vessel and gears.

The workshop will also apply the swept-area indices in defining a fish size indicator, and a marine litter indicator as case studies. These two cases studies are of great interest for their potential to be used as ecosystem indicators in ICES ecosystem overviews.

The workshop takes place at ICES Headquarters in Copenhagen in early January 2019.
