DEEP: Notice to Whelk and Eel Fishermen

Notice To Whelk and Eel Fishermen

April 19, 2013


In the past year some bait dealers in other states have begun to import small quantities of three species of Asian horseshoe crabs (Tachypleus gigas, Carcinoscorpius rotundicauda, and Tachypleus tridentatus) for use as bait in the eel and whelk fisheries. The use of these non-native species as bait in our waters raises potential concerns for the health of native marine resources.

These crabs, even though dead, can carry parasites. One species of parasitic flatworm lays eggs in tough cocoons on the shell of the Asian horseshoe crab, which can easily survive and hatch even if the host crab is killed. The introduction of such parasites could have detrimental effects on our native horseshoe crab population.

The United States Fish and Wildlife Service is moving to add these species to the Injurious Wildlife list of the Lacey Act so importation can be regulated on a federal level, however such action can take up to a year to put in place.

In the meantime, we ask your help in preventing the introduction of potentially harmful organisms to Long Island Sound by avoiding using non-native species as bait.
