Ziel der Reise / Objectives of Cruise:

Objectives: The survey has the main objective to annually assess the clupeoid resources of herring and sprat in the Baltic Sea in autumn. The reported acoustic survey is conducted every year to supply the ICES ? Herring Assessment Working Group for the Area South of 62?N (HAWG) and ? Baltic Fisheries Assessment Working Group (WGBFAS) with an index value for the stock size of herring and sprat in the Western Baltic area (Kattegat/Subdivisions 21 and Subdivisions 22, 23 and 24). Narrative: The 694th cruise of FRV "SOLEA" represents the 27th subsequent GERAS survey. FRV "SOLEA" left the port of Rostock/Marienehe on 30 September 2014. The acoustic survey covered the whole area of Subdivisions (SD) 21, 22, 23 and 24. Both on the northernmost transect in SD 24 as well as on some sections of the transect in SD 23, the course had to be changed and measurements interrupted due to area closures of the Swedish armed forces. Several days were lost due to medical emergencies. Accordingly, survey operations had to be shifted to daytime in order to cover the northern survey area of SD 21 in the remaining survey time. The survey ended on 20 October 2014 in Rostock/Marienehe.
