Ziel der Reise / Objectives of Cruise:
On this cruise, eight bachelor students of the Institute of Marine Ecosystem and Fishery Science (IMF) were given the opportunity to learn about the most commonly used scientific methods, gears and working procedures on board of a research vessel for fisheries science as well as biological oceanography. The chief object of the cruise was the investigation of distribution patterns of certain spawning fish species, such as cod, whiting, sprat, plaice, flounder and dab in the Kiel Bight, Mecklenburg Bight and in the Arkona Basin. In addition to fisheries, a comprehensive grid of plankton net stations was sampled in order to gain insights into the spatial distribution of fish eggs, planktivorous prey (larval to adult life stages) of sprat and cod larvae and plankton distribution (most important for sprat) from Kiel Bay towards Arkona Basin. Of special interest were the picoplankton communitys short term responses (on board) to temperature and salinity along the respective gradient in the Baltic Sea with an additional sampling scheme to later isolate Ostreococcus sp. and its associated viruses for future laboratory studies at the IMF.
