Sphyrion Tag Loss from the American Lobster Homarus americanus

Through use of a secondary mark, it was estimated that sphyrion tag loss from American lobsters Homarus americanus recaptured 1 year after tagging amounted to 36% for lobsters that had molted and 24% for those that had not. Much of the substantial tag loss from nonmolting animals may be due to substrate entanglement and removal by other lobsters.
