While visually ugly and wasteful on the surface, from a purely fish management perspective I have to agree with Parker. Figure there are equal attrocities going on out in front of the river fisheries by non tribal fisheries, just not as in your face. River chum have no value as table fare, as many on this board have attested. There is value in the eggs, apparently worth the effort to go after. The excess biomass goes back to the river. So other than a potential loss of recruitment, it is just a big pile of biomass going back to the river after they extract the economic value. Not pretty, but there are many other resource extraction industries that have similar approaches.
