Fig. 2

Images depicting the fates of acoustic tags in Atlantic salmon (Salmo salar) post-smolts following a 92-day monitoring period. A Incision from tag insertion (with retained sutures) has completely healed and there is no external sign of tag rejection. B Example of a tag that has been encapsulated by mesentery in the coelom of the fish. C Tag is starting to be expelled through the lateral surface of the dorsal musculature away from the incision. D Expulsion of the tag can be seen first as a bulge on the lateral surface of the fish, E culminating in it rupturing through the skin. F In the case of fish that did retain their tags, the tag was often seen lodged in one of the organ structures, such as in the pyloric ceca as depicted here
