Strict environmental regulations perhaps? Used to be that Alaskan buyers in Ketchican would process their fish and pump the waste out into the bay in what we called ‘bubble ups’ sea gulls and eagles loved them. But I never saw that method of disposal with Seattle based buyers -

Back in the days of my youth and right up through the 80s, at the marina down the street from my home, they used to clean or fillet the day's catch at dockside and throw the waste into the river. Needless to say, crabs were abundant, large and easily caught, and small baitfish as well that were feasting on the bounty. Now the heads, guts and racks (bones) are put into trash containers, which even though covered can get pretty smelly between pickups. The crab population is way down, too.

But the landfills are full and growing ... just what the wackos hate - putting the waste from cleaning fish back into the water is not pollution, but recycling: a concept over the heads of most envirowackos.
