In this data, NMFS helps hide the true halibut damage by putting it in terms of percentage of targeted catch. Since these vessels may hold +300,000 pounds, the percentages of halibut bycatch mean very large numbers of dead halibut. Insist on actual halibut numbers.
The true damage to Chinook stocks are hidden by the low observation rates for the catcher vessels. The Pacific Star, for instance might have had a bad day, or, that could be more common than the bean counters at NMFS will admit. NMFS is decidedly pro-trawler. Notice that it appears bottom dragging is the greatest Chinook killer this year, and mainly for very low value 'trash' fish.
