Table 1 Summary data for the present study. Area; the larger regional study area on the Norwegian coast for western (WN) and mid Norway (MN), the number in brackets refer to the number of spawning grounds monitored in each location. SP_M; the defined spawning period in months for each area. Study_Per; the present study period for the regional study areas. Fish were tagged and released every year at each spawning ground during the respective study periods. # cod; the number of mature cod retained in the final datasets post filterering and used for analyses of overall depth differences in the feeding and spawning period. Detections; the total number of detections in each dataset. #Codsp; the number of data – rich sexed mature cod selected for analyses, i.e. > 2000 detections and > 20 observational days, of periodic descents during the spawning period. Det_sp_dr; the total number of detections for the datarich cod in the spawning period. #Cfp; the number of data – rich cod selected for analyses of periodic descents during the feeding period, i.e. the months June to August. Det_fp_dr; the total number of detections for the data - rich cod in the feeding period.
