Christmas eve and that info brings out the cynic in me. Those fish were described as being excess at their hatcheries of origin but what does that mean?

If they would have been destroyed then this is good news. If they would have been reared and released anyway then transferring them to Minter is not a net increase but may have other benefits.

And now for the rest of the story (if anyone knows).
