Repeat spawning rate for the Mount Desert fishery is unknown. The Maine Department of Marine Resources manages this system for a commercial escapement of 35 fish per acre. The spawning escapement need for this system is 3,640 river herring passed upstream. The municipality of Mount Desert selects to keep the run closed for conservation at this time, though recent counts indicate that a harvest is possible. Fisheries staff will collect age and repeat spawning data at this location beginning in 2010. The spawning habitat at this location is limited and historically never produced large numbers of fish migrating to Somes Pond.
The fishway is a tidal fishway that is accessible only as the tide rises to meet the fishway entrance. This limits the opportunities for fish to access the fishway and spawning location upstream. This is common at several commercial harvest locations throughout the state. This emphasizes the need to maintain, clean, and monitor the tidal fish passages daily to ensure unobstructed upstream passage. The harvesters hired by the municipalities often fill this role, freeing state personnel to address other passage issues.
