In the Pacific (at least) there’s the concept of a “fish aggregating device” (FAD). Fishing boats build and deploy smallish structures that create a local environment that eventually results in the production of commercially valuable fish. Usually it’s just logs, rope, and such. Apart from the energy, an offshore wind farm would be a great sanctuary for fish. If you need to visit regularly for maintenance, bringing along a few extra FADs and the occasional marine biologist isn’t going to break the bank.
