Interesting developments in the estuary of the Campbell river on Vancouver Island.

Any idea how the nets don't do damage to the wild salmon that go into them?

The nets have a small mesh diameter and are strung tight, essentially acting like a wall for the fish, but allowing the water to flow past. So there's no chance of entanglement with this type of rigging. They swim up, then move laterally until they enter the collection and sorting area. Yes, there is potential for rubbing to occur, but these fish are at the maturation stage of up-river migration, so they are physiologically prepared for that kind of minor contact.
