Why when I was a kid we used to pull smelt from the Swinomish Channel boat docks in LaConner that were only slightly smaller. Took two or three to fill a large bucket. Now those were the days. Of course I was pretty little and that was a long time ago, but yeah those were really nice smelt. We must have over fished that race of giants, that bloodline, because them smelt are just little buggers now. What else could explain it but over fishing.
Then we would take the ferry to the islands and go net rabbits. Why we could fill up a truck bed in one night's haul with them pesty rabbits. Then they brought the foxes over and ruined that. Seems all the fun stuff is gone.
And there was a friend up along the Skagit east of the town of Concrete that ran a cedar mill and owned a stable of Belgian draft horses I believe they were. Why he roped a bear from a pickup once. Those were wild times. True story.
When you get old you drift sometimes. Don't need a boat either. Sometimes you even do it on purpose.
Jet sleds/boats destroy redds in the spawning grounds with their turbulent jet wash, scouring the bottom and further burying some of the eggs while ejecting the rest into the stream flow to be eaten. To protect fish, these boats must be restricted from the spawning grounds.
