For several years, we have tagged blue crabs in the Chesapeake Bay. Initially, we tagged only mature female blue crabs (from both the upper and lower Chesapeake Bay) to examine the timing and route of female migration to the spawning grounds at the mouth of the Bay. More recently we have begun to tag legal-sized male and female crabs to estimate the blue crab population size in the Rhode River as part of our larger study to assess the feasibility of blue crab stock enhancement in Chesapeake Bay. These tags consist of 1"x 2" pieces of hard pink plastic attached to the dorsal surface of the carapace with stainless steel wire. For each recaptured tagged blue crab please record tag number, capture location (GPS coordinates if able), capture date, and capture depth.
There is either a $5, $50 or $100 reward for individual recaptured tags. High-reward tags ($50 and $100) are marked accordingly on both sides of the tag. Every captor is also entered in yearly lottery drawings for $200 cash prizes. To see the latest crab tag lottery winners click here.
