They do not stock the lake anymore, no. The fish currently in it are considered invasive by the park and there are no catch limits.
It's odd the article poses this as a "problem" in an article about Crater Lake, where uniquely among lakes this "problem" is most likely to just fix the other problem.
Kill all the fish in the lake and the lake is better off.
It won't selectively kill fish, it'll kill frogs, turtles, algae, and anything else that lives in the water which isn't a bacteria or archaea capable of living in an anoxic environment. Possibly also the predators of those species which live on land.

That's a bit dramatic. Frogs, turtles, salamanders, etc, can breathe air.
The only predators are birds, who can find food at any of the many other lakes in the area.
Crater Lake's geography is essentially unique among lakes that may be having this issue. There is a near-total lack of native fauna that would be affected by an anoxic event.
