Description:

Total return to USA rivers was 2,613; this is the sum of documented returns to traps and returns estimated on selected Maine rivers. Adult salmon returns to USA rivers with traps or weirs totaled 2,506 in 2008, a 106% more than observed in 2007 and 76% more than returned in 2006. One hundred and thirty eight (90% CI = 106 - 178) adult salmon were estimated to return to the rivers with Endangered populations, the 10th highest for the 1991-2008 time-series. Most returns occurred in Maine, with the Penobscot River accounting for 81% of the total return. Overall, 31% of the adult returns to the USA were 1SW salmon and 69% were MSW salmon. Most (84%) returns were of hatchery smolt origin and the balance (16%) originated from either natural reproduction or hatchery fry. A total of 12,534,300 juvenile salmon (fry, parr, and smolts) and 5,848 adults were stocked, with 468,246 carrying a variety of marks and/or tags. Eggs for USA hatchery programs were taken from 450 sea-run females, 2,882 captive/domestic females, and 146 female kelts. The number of females (3,480) contributing was less than 2007 (3,940); and total egg take (19,579,000) was also less than in 2006 (22,074,000). Production of farmed salmon in Maine was reported to be 9,014 metric tonnes in 2008, just over three times the 2,715 metric tonnes of production reported in 2007.
