Twenty years ago we could harvest clams all summer long. At present, we have twice the population, so we should be able to harvest 1/2 the summer. Right?? 1/2 * 2 = 1, right?? This is the type of math I understand. WDFW math I do not understand. 6-10 days of clamming a year I do not understand. A Lake Wa sockeye escapement requirement of 350,,000 fish for one river I do not understand. A 3 dollar per fish cost to count harvested Lake Wa sockeye I do not understand.
