Several ways to help limit LMB over crowding.

Seine (net) the nests while the young are there and remove as many as possible. Even if you don't get them all it will run off the male which will also help. Can also rotenone them. Not sure rotenone is legal in Italy.

Those are indeed PS and will not reproduce enough to sustain LMB. Are there any other forage species available?

Can also catch (fishing) some adults for food and seine net out some adults also.
