Examples of escapement in a Sentence

Recent Examples on the Web The low sockeye escapement figures continue despite managers closing the regular, 12-hour Thursday fishing periods during the second and third weeks of the fishery. Elwood Brehmer, Anchorage Daily News, "Copper River sockeye fishery improves, but the run remains below normal," 5 June 2020 Through June 15 just 1,165 large kings had been counted on the Kenai, much less than the minimum optimal escapement goal of 3,900 fish. Elwood Brehmer, Anchorage Daily News, "Poor Kenai River king salmon returns will restrict start of Cook Inlet commercial fishery," 18 June 2020 But because the fish moved all at once in a huge slug, faster than the fishermen could catch them, thousands more passed upstream than the escapement goal. Miranda Weiss, Wired, "In Alaska, Summer's Getting Too Hot for the Salmon Run," 13 June 2020 The run is still better than 2018 when low sockeye returns forced managers to greatly restrict fishing time to achieve sufficient escapement. Elwood Brehmer, Anchorage Daily News, "Copper River sockeye fishery improves, but the run remains below normal," 5 June 2020 Nearly 50 million sockeye are expected to return to Bristol Bay rivers this summer and not catching the vast majority of them would make for salmon escapements that would far exceed the goals for each river. Elwood Brehmer, Anchorage Daily News, "Safe conduct of Alaska salmon fisheries is possible during coronavirus crisis, Fish and Game says," 16 Apr. 2020 The piece is equipped with a constant force mechanism called a remontoire that controls the heartbeat of the watch, transferring power between the mainspring and escapement to ensure its stability in timekeeping. Victoria Gomelsky, New York Times, "A Collection of Female Watch Collectors," 8 Mar. 2020 The Susitna River drainage is managed for an escapement of 10,200 to 24,100 coho salmon, while the combined goal for Chelanta, Judd and Larson Lake -- the three main sockeye-producing lakes in the drainage -- is about 50,000 to 120,000 sockeye. Matt Tunseth, Anchorage Daily News, "Alaska Board of Fish creates new dipnet fishery on the Susitna River," 14 Feb. 2020 The return would be about 60% larger than last year’s escapement of just 12,780 fish, which failed to meet the department’s sustainable escapement goal of 13,500 to 27,000 fish. USA TODAY, "Mammoth Cave sharks, waterfall chasing, Valentine’s divorce: News from around our 50 states," 31 Jan. 2020
