I have to enter my thoughts here..
We spend thousands upon thousands on electrofishing equipment and then measure and weigh in inches and pounds/ounces.
mm and grams are in order. It's been proven to me time after time that pounds/ounces/inches can create up to a 15% error in WR and bad assumptions are made because corners were cut on accuracy.
This is something I don't think is "good" in fisheries management, if it isn't as accurate as possible, how can you adjust or manage with faulty data????
Sorry guys, I'm OCD with this particular step.
