Sorry I can't always get into words what i am thinking. Dom did a great job.

The same number of fish were caught and kept in the same period of time as if it were a two fish limit. Bingo!
Thus any extension of the season was not going to happen based on a good fishery/ catch rates. The reason fishing was so good is because there was a ton of fish in the river. The only way to extend the season is to have closed it more than 1 day a week.
