Fish Recycling

For reasons unknown even to myself, I receive the US Fish and Wildlife Services fish count emails for places like Foster Dam, Oregon. While not much can be gleaned from the numbers themselves, (sometimes up, sometimes down, always too few to be encouraging) the reports reveal other aspects of the business of dams and fisheries that might go otherwise unnoticed. Like recycling.
Fish recycling, that is. Recycling in fisheries speak is what humans would call shuttling. Like in rafting, when after the float you have someone pick you up and shuttle you back to your vehicle at the top of the run, presumably to have another go. This is what they do with the fish.
So what they do is, they manufacture thousands of tiny test tube fish and release them into the river, presumably to help sustain the wild populations. Then they wait for them to return, and scoop them up and drive them upstream to harvest their eggs. They then scoop them back up and drive downstream to the most popular fishing holes, and let them see if they can get past the anglers.
This is our tax dollars rigorously at work implementing our wildlife and resource management policies.
This year’s recycling program at Foster Dam will end September 1.
