The Mar Pacifico caught an average of 21 Chinook per tow for those 15 observed tows. If we knew the target species caught in those tows and the total for the season, we could extrapolate the total seasonal catch of Chinook for the Mar Pacifico. There is probably a fudge factor multiplier estimating error. In other words, we don't have evidence that is solid, ground truthed fact. But we do know that observed catches are cleaner than the unobserved catches, so we presume the actual catches are way out there beyond acceptability. That's they way the drag fleet likes it.

Put those together with the model they use for projecting reality, shake in a Martini shaker and voila! Then adjust downward if the draggers kick too much.<br />Wiglafhttps://www.blogger.com/profile/14357031507262299517noreply@blogger.comtag:blogger.com,1999:blog-5248187375964492769.post-61773887957110762992012-11-22T20:49:39.400-08:002012-11-22T20:49:39.400-08:00So I understand that when they do the halibut numb...So I understand that when they do the halibut numbers on that spreadsheet that it is kg/mt.
