A tough part of fisheries management to be sure ... however, the state has a long record of the "kill 'em first, count 'em later" mentality. Given this record, it is time to see this come to an end ... why not start conservative with fishing harvest and adjust from there?? Keeping count of in-river escapement can be done with a decent degree of accuracy: it is the manner in which all the streams in the area I fish in AK are managed. NO reason it can't work there too. Fish first!
