Description:Total return to USA rivers was 626; this is the sum of documented returns to traps and returns estimated by redd counts on selected Maine rivers, this year ranks 24 out of 26 years for the 1991-2016 time series, but represents a 164% increase over 2014 (the lowest in the time series) and only 15% of the recent high return number in 2011. Adult salmon returns to USA rivers with traps or weirs totaled 564 in 2016. Estimated return to Gulf of Maine small coastal rivers was 62 adult salmon. Most returns occurred to the Gulf of Maine Distinct Population Segment, which includes the Penobscot River and eastern Maine coastal rivers, accounting for 98% of the total return. Overall, 37.1% of the adult returns to the USA were 1SW salmon, 62.1% were 2SW salmon and 0.8% were 3SW or repeat spawners. Most (72 %) returns were of hatchery smolt origin and the balance (28%) originated from either natural reproduction or parr, hatchery fry and eggs. A total of 4,936,654 juvenile salmon (eggs, fry, parr, and smolts), and 3,757 adults were stocked in 2016. Of those fish 323,392 carried a variety of marks and/or tags. Eggs for USA hatchery programs were taken from 134 sea-run females and 1,620 captive/domestic and domestic females. Total egg take (5,426,096) was lower than the previous three years by nearly 1,000,000 eggs even with an increase of almost 200 spawners. Production of farmed salmon in Maine was not available, due to regulation concerning privacy.
