NOAA Fisheries is checking the genetic range of Atlantic salmon making sure that salmon born in hatcheries might have a good possibility at surviving within the wild. We also want to make certain that wild salmon are genetically numerous which range is taken care of in the captive broodstock lines held in the hatchery.
Migration of adult Atlantic salmon could possibly be confined by beaver dams in the course of durations of minimal stream flows, nevertheless the existence of juvenile salmon upstream in the dams suggests They may be penetrated by parr.[29] Downstream migration of Atlantic salmon smolts was similarly unaffected by beaver dams, even in periods of very low flows.[29]
Obtaining remaining their natal streams, they experience a duration of quick expansion through the one to 4 decades they live in the ocean. Normally, Atlantic salmon migrate from their residence streams to a region about the continental plate off West Greenland.

Expanding numbers of hatchery-raised Atlantic salmon smolts are coming into the ocean through the Gulf of Maine, but fewer are returning to spawn, elevating thoughts concerning what is happening to those fish at sea.
NOAA Fisheries conducts several investigation functions around the biology, conduct, and populace health of Atlantic salmon. The outcome of this study are employed to inform administration choices for this species.
Young salmon shell out two to three many years from the rivers and streams of Maine, then bear Bodily adjustments to prepare them for all times in the ocean. The moment Gulf of Maine Atlantic salmon go away Maine streams and rivers, they migrate into the ocean.
