Mischka, apologies as my comment regarding the typo seems a bit snarky as I read it now. 
The point I am trying to make is that Halibut are part of an ecosystem that is in danger. We all know the various species of Salmon are declining rapidly. Predator species like Orcas & Whales are in danger as the food chain is degrading. 
Clearly there is massive evidence provided by scientists that all the oceans are being affected by pollution and climate change. Only the Pollution Defenders aka climate deniers are unwilling to accept this evidence.
This will be the 1st summer in human history when there will be no ice cover on the North Pole. The ice used to reflect 85% of solar radiation. Open water reflects only 6%. This temperature increase will speed up an already cascading degradation in the ocean waters. This is a much larger issue than local fishing regulations.
We all need to unite to decide how to deal with these issues that could very well lead to human extinction.
