Distribution, abundance, dredge efficiency, population structure and utilitation coefficient in catches of green sea urchin (Strongylocentrotus droebachiensis) in the southern part of Breiðafjörður, West Iceland. HV 2018-42

Útbreiðsla og stofnstærð ígulkersins skollakopps (Strongylocentrotus droebachiensis) var könnuð í september 2015 og október 2016 á aðalveiðisvæði í sunnanverðan Breiðafirði (suður af línu 65°10´N og austur af línu 22°40´W). Heildarstærð veiðisvæðis var áætlað 9.7 km2 og fundust ígulker í töluverðu magni á sjö undirsvæðum innan þess.

A dredge survey was conducted in September 2015 and April 2016 to provide the first assessment of sea urchin resources in southern Breiðafjörður (south of line 65°10´N and east of line 22°40´W) at 8 – 60 m depth. The whole area investigated was 9.7 km2. Sea urchins were patchy distributed in significant concentration in seven (I‐VII) small subareas within the investigated area.
