I will reiterate that the absolute fastest way to get food to the SRKW's is for humans to stop killing the food they eat and stop killing the food of the food they eat. The second fastest would be removal of the smolt-eating pinnipeds. Kill them, and in 3,4,5 years more adults might come back if fisheries don't kill them first.

Although the most obvious, pinnipeds eating adult salmonids may not be a great issue for the SRKW's because the salmon have passed the whales by; the pinnipeds eat fish that the whales don't/won't access.

But, getting the Save the Whales group onboard for habitat issues brings more power to the battle. Won't save the whales, but may get rid of reasonably useless dams.
