Topic Fish: Downstream Migrant Salmon Counts in Sheepscot River 1956-1959

Caption:  The Chart Table "fish_dsmt_sheep_stickney_1956_1999.db" contains number of Atlantic salmon smolts caught each year in the Sheepscot River from 1956-1959 at a weir at Head Tide Dam operated by the U.S. Fish and Wildlife Service and the Maine Atlantic Salmon Commission, from Stickney (1959). Due to an earlier ice-out date, traps began operating several weeks earlier in the season in 1957 and 1959 than in 1956 and 19580. Because of this, counts for 1956 and 1958 are incomplete and the actual numbers of fish were likely substantially greater than is shown in these data, especially for wild smolts because they emigrated earlier than hatchery smolts. Because the trapping presumable missed nearly the entire wild smolt migration in 1956 and 1958, no estimates of wild smolt numbers were made for those years. See Info Links for more information and a link to the original document. A Key to column headings: Year = year, Weir_count_1yr = Number of 1-year-old hatchery smolts caught at weir, Weir_count_2yr = Number of 1-year-old hatchery smolts caught at weir, Weir_count_wild = Number of wild smolts caught at weir, Weir_count_total = Total number of smolts caught at weir, Estimated_count_1yr = Estimated number of 1-year-old hatchery smolts, Estimated_count_2yr = Estimated number of 2-year-old hatchery smolts, Estimated_count_wild = Estimated number of wild smolts, Estimated_count_total = Estimated total number smolts.
