The National Oceanic and Atmospheric Administration (NOAA) has dismissed arguments against its new halibut bycatch rule as 'too vague and ambiguous.' The rule, which reduces the prohibited species catch limit by 35% when halibut abundance is low, has been challenged by the Groundfish Forum, a group representing several fishing companies. The Forum claims the rule is causing severe economic losses and is seeking a fixed bycatch limit of 1,745 metric tons for the Amendment 80 fleet. However, NOAA has countered that the Forum's complaint 'has failed to state a claim upon which relief can be granted.'
