PORTLAND, Maine (WABI) - U.S. regulators are allowing teams to return to freeing most whales tangled in fishing line.
The National Oceanic and Atmospheric Administration suspended such efforts last week to review safety protocols.
It came days after 59-year-old Joe Howlett of Campobello was killed while freeing a right whale off New Brunswick, Canada.
NOAA says it'll allow teams to begin disentangling whales again, except right whales.
North Atlantic right whales are among the most endangered marine mammals in the world.
NOAA says the whales' unpredictable behavior can be particularly challenging during rescue attempts.
NOAA says it plans to continue working closely with whale experts to review all rescue protocols for large whales.
