2024 - Snow Crab movement study in the southern Gulf of St. Lawrence

Moncton and Quebec – March 22, 2024

Fisheries and Oceans Canada (DFO) is informing snow crab fish harvesters fishing in the southern Gulf of St. Lawrence of a study being conducted by DFO Science to better understand the movement of snow crab.

What to do if you capture a tagged snow crab?

• Record the tag number, the date and position of catch (minimum information required for the study) and then return the tagged crab (without cutting off the tag) to the water as soon as possible. Returning the tagged snow crab at sea allows multiple recaptures of the same animal during its lifespan.
• The following information would also be beneficial to DFO:
• Name and mailing or e-mail address of person reporting the tagged crab
• name of fishing vessel;
• catch position; and
• any other information associated with the catch of the tagged snow crab such as carapace condition, water temperature and/or depth of water at catch position (fathoms).
• We currently have two types tags deployed: the first being a spaghetti-shaped plastic tube (usually red in color) with a numbered plate secured around the crab’s body and a second is an acoustic tag (similar to the size of a AA battery) fixed on the back of the carapace. Please record any numbers related to the tags in your submission of tag information.

The information can be emailed to: Stephanie.boudreau@df0-mpo.gc.ca, sent by text to (506) 377-2037 or sent by mail to the following address:
