摘要：
The growth rate and annual production of the crayfish Cambarus bartonii were estimated in Crouch Run, a 3rd-order stream that drains a high-elevation catchment in West Virginia and which has been acidified because of acidic precipitation. Production of C, bartonii in Crouch Run was 525.8 mg AFDW m(-2) yr(-1) and was less than that for C, bartonii in Upper Ball Creek, a high-elevation circumneutral stream in North Carolina (961.0 mg AFDW m(-2) yr(-1), Huryn & Wallace, 1987). This difference seemed to be related to differences in the biomass of C. bartonii between the streams, because the P/B ratio for C. bartonii in Crouch Run was 1.4 compared with 5.8 in Upper Ball Creek.
