In September 2011, we tagged about 5,000 lobsters off the coasts of Laguna, Point Loma, and South La Jolla in zones slated to become MPAs. Each green tag is inserted into the back of the lobster between the tail and the upper section of the exoskeleton called the carapace. The tags are numbered and information on the lobster’s GPS coordinates, sex, reproductive state, and size are recorded corresponding to the tag number so that researchers can learn how the lobster travels in and out of the MPA (spillover), its growth rate, and other relevant information when the lobster is recaptured.
