The NMFS admits that they need more observers, and they asked for a pile of money to do it last year. I don't know if they got the funding. I am guessing its a low priority.

2-3% can be a statistically valid sample, what percentage of the voting public do you think those presidential polls use? A small sample increases the margin for error (standard deviation) but even with a 2-3% sampling rate, all else being equal (i.e. times of year, fishing areas, etc) their current statistics do indicate little bycatch in the sea herring fishery. I'm not saying that figures are gospel, but even if they were double, it would indicate little bycatch in the sea herring fishery.
