Whilst movements of organisms have been studied across a myriad of environments, information is often lacking regarding spatio-seasonal patterning in complex temperate coastal systems. Highly mobile fish form an integral part of marine food webs providing linkages within habitats, between patches of habitats and at different life stages. We investigated how movement, activity and connectivity patterns of Atlantic cod (Gadus morhua) are influenced by dynamic environmental conditions. Movement patterns of 39 juvenile and subadult Atlantic cod were assessed in two coastal sites in the Swedish Skagerrak for 5 months. We used passive acoustic telemetry and network analysis to assess seasonal and spatial movement patterns of cod and their relationships to different environmental factors, using statistical correlations, analysis of recurrent spatial motifs and generalised linear mixed models. Temperature, in combination with physical barriers, precludes significant connectivity (complex motifs) within the system. ... : Acoustic telemetry detections_DryadDetections of Atlantic cod using acoustic telemetryStation_attributes_DryadInformation; co-ordinates, depth, name of the stations / acoustic receiversEnvironmental data_DyradDaily data from weather station. e.g. sea surface temperature, wind speed/direction ...
