State of Maine Anadromous Fisheries Goals State of Maine Statewide Fisheries Management Plan, June 1982 To restore, maintain, and enhance anadromous fish resources for the benefit of the people of Maine To provide increased employment through the expansion of commercial and recreational fisheries for anadromous fish resources.
Kennebec River Watershed Fisheries Restoration Goal Restore river herring, American shad, striped bass, rainbow smelt,Atlantic sturgeon, and shortnose sturgeon, to their historic range
Strategic and Operational Plan for the Restoration of Shad and Alewives Goal: To restore the alewife and shad resources to their historical range in the Kennebec River system –Objective: To achieve and annual production of 6.0 million alewives above Augusta –Objective: To achieve an annual production of 725,000 shad above Augusta
Anadromous Life History 1 - 5 years FW SW adult egg 1 summer in FW juvenile 3-5 years in SW
Alewife life history Adults migrate upriver from the ocean to spawn in lakes and ponds at ages 4- 9 from mid-May to early June (repeat spawn) Juveniles migrate downstream from lakes to ocean in August-Sept Planktonic feeders primarily Range from Newfoundland to North Carolina
Importance of Alewives Important prey fish for coastal and inland fish species Important prey source for bald eagles, osprey, king fishers, fur bearing mammals Important source of bait for the spring lobster fishery
Causes of decline Lack of access to upstream spawning and nursery habitat and access downstream to the ocean due to dams Degraded habitat Poor water quality Soil erosion Reduced riparian cover Overfishing
