>In fact, it would affect anadromous and catadromous fish the same way- it would kill most of them off. There are significant physiological (and physiologically stressful) changes that must occur before a salmon, say, can move to fresh water or an eel can move to the ocean. If it's the wrong time of year or the wrong point in their life cycle they're not going survive.
Possibly not; I'm not an ichthyologist (or for that matter,
any sort of biologist), and I assumed it was a matter of
gradual adaptation during migration, perhaps by loitering at
river mouths or in brackish estuaries for some period of
time to allow "rebalancing" of salt tolerance. And I should
have included "non-catadromous" as well, even though as you
note it was wrong to single out non-migratory species.
And of course, there's still that "sow the fields with salt"
issue... ;-)
