During last summer they started to get
semicircular wounds on their bodies and one had it's face eaten away.

This is not the kind of damage a dragonfly nymph would do. And it would not
attack large fish.
Dragonfly nymphs prey on fish fry and very small fish. They grab them with
their jaw parts (think the second set of teeth in Alien) and then they tear
their prey apart and eat it. There would never be a circular wound.
