Topic	Fish: Electrofishing at 24 Mattole Stations, 1972, Steelhead Vs Coho

Caption:  The Chart Table fish_brown_mattole_1972.dbf contains summary data from electrofishing surveys in the Mattole Basin conducted in 1972. Sub-basin is the NCWAP subbasin designation, FISH_100FT = number of salmonids estimated per 100 feet of stream in sampled area, 95_CI = the 95% confidence interval for fish population derived from mark-recapture. SURF_AREA = surface area of the stream sampling reach, FISH_SQ_YD = salmonids per square yard, SH_0_pct = the percentage of young of the year steelhead in the sample, SH_1_pct = percent of yearling and older steelhead in the sample, COHO_pct = coho salmon juveniles as a percent of the sample. All PCTD = percent of community multiplied times densities.
