Abstract |
This paper describes a crab tagging method with a potential for retention during ecdysis. Miniature ferromagnetic tags are injected magnetically into they dactylus of crab legs and are recovered in commercial landings using a magnetic detector. The method was tested in the field and shown to be practical for the rapid tagging of large numbers of crabs at sea. A statistically valid estimate of stock size was calculated. |
