Migratory fish were not addressed in the species analysis of the LNE Plan 2000, but a tabulationof the migratory fish species in these EDUs shows migratory fish occur in each EDU. Thusmaintaining functional connected stream networks from headwaters to the ocean for migratoryfish will be critical in all EDUs. The migratory fish by EDU are listed in Table 2. These fishinclude diadromous fish, which move between freshwater and saltwater, and potamodromousfish which move entirely within freshwater. Anadromous species spawn in freshwater andprimarily grow in salt water. Catadromous species spawn in saltwater and primarily grow infreshwater. Amphidromous species may spawn and grow in either freshwater or saltwater, buthave a migration to the opposite habitat for feeding and this migration is usually brief.Potamodromous fish move entirely within freshwater during their lifecycle – from as little as 1mile to over 100 miles.Table 2: Migratory Fish Distribution by Ecological Drainage UnitMigratory Fish by Ecological Drainage UnitLife History Saco-Merrimack-Charles Upper Connecticut Middle Connecticut Lower Connecticut Cape CodAnadromous Atlantic Sturgeon Rainbow Smelt Atlantic Sturgeon Atlantic Sturgeon Blueback HerringBlueback Herring Sea Lamprey Blueback Herring Blueback Herring AlewifeAlewife Atlantic Salmon Striped Bass Alewife American ShadAmerican Shad Sea Lamprey Smerican Shad Striped BassStriped Bass Atlantic Salmon Striped Bass Rainbow SmeltRainbow Smelt Rainbow Smelt Sea LampreySea LampreyAtlantic SalmonSea LampreyAtlantic SalmonCatadromous American Eel American Eel American Eel American Eel American EelAmphidromous Shortnose Sturgeon Banded Killifish Stortnose Sturgeon Shortnose Sturgeon Shortnose SturgeonHickory Shad Banded Killifish Hickory Shad Hickory ShadBanded Killifish White Perch Fourspine Stickleback Fourspine SticklebackRainwater Killifish Sheepshead Minnow Gizzard ShadWhite Perch Gizzard Shad Banded KillifishNinespine Stickleback Banded Killifish Rainwater KillifishWhite PerchWhite PerchNinespine Stickleback Ninespine SticklebackPotamodromous Lake Whitefish Lake Whitefish Lake Whitefish Brook Trout Brook TroutBrook Trout Brook Trout Brook TroutREVISED 6/2003AQUA-RESULTS-5
