Abstract:
This data contains monitoring data of the RV ALKOR cruise AL607 conducted in February 2024 (February 10th – February 16th) in the Western Baltic Sea by the University of Hamburg. Sampling activities conducted during this teaching cruise was part of the international sampling efforts to investigate the spawning activity of Western Baltic cod (Gadus morhua) coordinated by the Western Baltic cod Forum (WBCF). The data set includes cod single fish analysis data. All single fish measurements were made directly on board. Full wet weights of cod were measured and subsequently cod were gutted and liver weights, gonad weights and sexes, gutted wet weights (i.e., gutted wet mass), gonad stages and liver nematode infestations were recorded, and Otoliths were taken.
