Mussel farms in New Zealand serve as mid-water artificial reefs providing novel foraging/breeding habitat and a refuge from predators that enhance recreational and sport fishing. Fishermen report good catches around the mussel lines, which attract a wide range of fish species through the easy availability of food. Entrepreneurial operators have taken advantage of the mussel farms to create a thriving tourism experience.

Catalina Sea Ranch welcomes fishermen to tie up to buoys connected to submerged cultivation gear which, like the offshore oil platforms will create habitat for aggregating marine life. Tourists, charter boats and sport fisherman are encouraged to fish our offshore ranch.
