Salmon require gradual brackish estuaries to survive their saltwater transition

Evidence

The transition to salt water is a major assault on the body chemistry of a salmon born in freshwater. One fish biologist likens it to the rigors of a chemotherapy transfusion. The fish need a gradual transition zone, a halfway house of sorts. The brackish water of estuaries, the wetland buffer between river and ocean, plays a critical role in salmon survival. — Robin Wall Kimmerer, Braiding Sweetgrass, 892
