Most of the delayed release will stay in the Sound while only some of the fingerlings. It becomes a math exercise. When survival rates are high enough, the yearlings support a fishery. When they fall low enough, as they have, they actually return numerically fewer fish.

Remember, too, that the delayed releases will number in the thousands, maybe hundreds of thousands while fingerling releases can be in the millions.

And, as noted, it is money and water. I believe that yearlings released from freshwater are the ones that residualize at high rates. Apparently, the trigger to stay is age at saltwater entry so raising yearling in marine net pens was not as good a way to go. And, of course, it costs a lot less to produce the smaller fish.
