Fig. 7. Two-day averaged maximum depth profiles for four Pacific halibut that demonstrate the general seasonal behaviors observed across all tagged fish (n = 72). A) Summer residence on the continental shelf with an offshore autumn migration and occupation of deep slope waters in winter (n = 54 fish). B) Use of continental slope habitat throughout the year (n = 6). C) Use of slope habitat in summer and shelf residence in autumn and winter (n = 1). D) Full-time shelf residence (n = 11). Gaps in the depth profiles of fish depicted in panels B and C represent data that were not received during satellite transmissions; tags for the fish depicted in panels A and D were physically recovered.
