You have lobster traps that not only catch lobster. They're essentially fish traps and they're designed to catch lobster. They catch other fish as well, like sculpins and wolffish. Wolffish now have a mandatory release back into the water, alive if possible, because this species is protected under the Species at Risk Act now. A number of fish species that co-occur with lobster also go into the trap, attracted by the same bait that the lobster is attracted to. A lot of these species are then in turn used as bait by fishermen, so they don't survive the bycatch process. It then depends again on the objectives of MPA if that bycatch problem needs to be addressed and how serious a threat it is to the objectives of the MPA.
