There is a freshwater sardine in the Philippines which is vulnerable from overfishing. Perhaps it could be trained to live in saltwater.

Salmon can famously survive in both environments at different times in their life cycle.

Freshwater fish account for about 40% of the species even though only about 2.5% of the earth's surface is freshwater. If vulnerable freshwater species could be trained to live in saltwater, that would ease conservation efforts, particularly for cavefish

Of course, the introduction of the Nile perch to Lake Victoria shows the dangers of invasive species.
