Description:Total returns to USA rivers in 2021 was 680 salmon; this is the sum of documented returns to traps and returns estimated by redd counts. Returns to the USA ranks 28th out of the 31-year time series (1991- 2021) and 47th out of the full 55-year time series (1967-2021). Most returns (676; 99.4%) were to the Gulf of Maine Distinct Population Segment (GoM DPS), which includes the Penobscot River, Kennebec River, Sheepscot River and Eastern Maine coastal rivers with only 4 returns documented outside of the GoM DPS. Documented returns to traps totaled 591 and returns estimated by redd counts were 85 adult salmon. Overall, 34.6% of the adult returns to the USA were 1SW salmon, 63.8% were 2SW salmon and 1.7% were 3SW or repeat spawners. Most (77.6%) returns were of hatchery smolt origin and the balance (23.4%) originated from either natural reproduction, hatchery fry, or planted eggs. A total of approximately 4,404,500 juvenile salmon (eggs, hatchery fry, parr, and 1 smolt), and 2,212 adults were stocked into U.S. rivers. Atlantic salmon at various origins and life-stages had marks applied during the year, with a total of 116,711 marks administered in 2021. Eggs for USA hatchery programs were taken from a total of 1,370 females consisting of 77 sea-run females and 1,293 captive/domestic and domestic females. Total egg take (5,266,000) was lower than the previous year of 6,404,000 eggs. Production of farmed salmon in Maine was not available, due to regulations concerning privacy.
