So minus the chemicals, they're actually somewhat of a benefit from that waste stream in terms of prawn enhancement. That's interesting.
Now, going way back--and this is maybe just getting muddied in details--I was interested when you were talking about the sea lion kills. I certainly know this isn't a palatable justification for it, but just out of curiosity I'm wondering if there is any benefit to the Pacific wild salmon from the predators being shot.
