It seems that straight ceremonial harvest are most likely to include a number. The subsistence aspect of this leave the amount open. I personally talked to a couple of netters on the skok that were aiming for 6 totes from one net (set as a trap) for the day. I was there in the afternoon and they had just filled up their 3rd and 4th totes.

During the king season, the Nisqually tribe states they took over 1500 fish a day. So, while the chance of them hitting it hard is very slim, they could. A simple cap would add a lot of clarity.
