I'm certainly not an expert on what the rules were in the 1970s related to trawling, but what I can tell you is that in our current rules, there are at-sea observers that are deployed, there are strict gear requirements, and there are dockside monitoring and ongoing quota monitoring to ensure these fishing approaches don't result in quota overruns.
All of this is predicated on a very robust scientific basis for setting the total allowable catch, which is based on robust world-class monitoring to ensure the removals that are being authorized are sustainable, and then, as I say, all of the measures that are in place to ensure those sustainable levels are adhered to.
