WebDiadromy is a term used to describe migrations of fishes between fresh waters and the sea; these migrations are regular, physiologically mediated movements which occur at predictable life history phases in each diadromous species, they involve most members of a species' populations, and they are usually obligatory. Around 250 fish species are … Diadromous fish are a special group of fish that have the ability to migrate between the ocean and freshwater. Well-known diadromous fish—such as shad, river herring, salmon and eels—serve several vital ecosystem functions throughout their life cycle. During spawning migrations, they provide a … See more Prior to European colonization of New England, the Merrimack River and tributaries supported staggering populations of diadromous fish. The American shad run was particularly impressive. One … See more As the Industrial Revolution began in America in the late 1700s and early 1800s, the Merrimack River watershed saw the construction of many dams. Spurred by the need for power to … See more Today, with more than 3,000 barriers in the watershed, habitat connectivity remains the biggest challenge facing the restoration of diadromous fish. Many of the large dams that originally provided power for mills have since … See more By the 1860s, resource managers decided to act in an attempt to restore these fish. By 1866, they began building the first “fishways”—structures such as fish ladders that allow fish to pass over a dam or other obstruction. … See more WebDiadromy.
