So let's make this clear - is it closed to bottom bouncing or is it open to bottom bouncing?
The only answer is "Yes".
To quote DFO NOTICE FN0772 (that's the one that opened the river on August 3rd):
"There is no retention of sockeye salmon permitted at this time. Given the low abundance of sockeye and the expected en-route mortality, impacts on sockeye are to be minimized and DFO is working with all users of the resource to limit impacts on sockeye.
While fishing for pink, chinook and chum salmon, anglers should avoid using fishing methods that catch sockeye salmon and fish selectively.
The first principle of selective harvesting is to avoid catching non-targeted stocks. This means that anglers should use methods that do not catch sockeye. The following fishing methods enable anglers to catch pink, chinook and chum salmon and rarely intercept sockeye salmon:
Bar Fishing
Trolling Spoons at Creek mouths
Float Fishing
Pulling Plugs
Fly Fishing
We encourage anglers to continue to use these methods to target pink, chinook and chum while avoiding sockeye.
Please note that bottom bouncing is NOT considered a selective fishing method and is strongly discouraged. The Department requests that selective fishing techniques be used and will continue to closely monitor the situation to ensure impacts on sockeye are at a minimum.
Should DFO feel that the rate of compliance is insufficient to ensure the adequate passage of sockeye, spot closures or a "no fishing for salmon" restriction may result."
