Advice on the dimensions of the escape mechanism in American lobster (Homarus Americanus) commercial fishing traps in the southern Gulf of St. Lawrence

Regional Peer Review – Gulf Region

Chairperson: Jenni McDermid


The escape mechanism on commercial American lobster (Homarus Americanus) fishing traps is a key conservation measure as it allows under-sized lobsters to exit the trap. This in turn reduces injury and mortality to these lobsters, both within the traps (e.g. from other lobsters) and at the surface (e.g. from handling). The minimum required height and length of the escape mechanism form part of the lobster license conditions and are dependent on the Minimum Legal Size (MLS) as larger lobsters need larger openings to exit the traps. Previous advice was provided by DFO Science on the height and length of escape mechanisms but the maximum MLS considered was 80 mm. Further advice is now needed as the MLS is now above 80 mm in Lobster Fishing Area (LFA) 26B, and may eventually reach 80 mm or above in other LFAs.


Develop science advice on the dimensions of the escape mechanism in commercial lobster fishing traps at MLSs of 80 mm and above.
