Description:Total return to USA rivers was 921; this is the sum of documented returns to traps and returns estimated by redd counts on selected Maine rivers, this is the fourth lowest for the 1991-2015 time series, 204% increase over 2014 (the lowest in the time series) and only 22% of the recent high return number in 2011. Adult salmon returns to USA rivers with traps or weirs totaled 803 in 2015. Estimated return to Gulf of Maine small coastal rivers was 118 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 96% of the total return. Overall, 16% of the adult returns to the USA were 1SW salmon, 83% were 2SW salmon and 1% were 3SW or repeat spawners. Most (80%) returns were of hatchery smolt origin and the balance (20%) originated from either natural reproduction or hatchery fry and eggs. A total of 4,044,000 juvenile salmon (eggs, fry, parr, and smolts), and 4,271 adults were stocked in 2015. Of those fish 328,792 juveniles carried a variety of marks and/or tags. Eggs for USA hatchery programs were taken from 348 sea-run females and 1,243 captive/domestic and domestic females. The total number of females (1,591) contributing was similar to 2013 (1,577); and the total egg take (6,962,000) was similar to 2014 (6,520,000). Production of farmed salmon in Maine was not available, due to regulation concerning privacy.
