Mb. Griffith et al., PRODUCTION OF THE CRAYFISH CAMBARUS-BARTONII (FABRICIUS, 1798) (DECAPODA, CAMBARIDAE) IN AN ACIDIC APPALACHIAN STREAM (USA), Crustaceana, 69, 1996, pp. 974-984
The growth rate and annual production of the crayfish Cambarus bartoni
i were estimated in Crouch Run, a 3rd-order stream that drains a high-
elevation catchment in West Virginia and which has been acidified beca
use of acidic precipitation. Production of C, bartonii in Crouch Run w
as 525.8 mg AFDW m(-2) yr(-1) and was less than that for C, bartonii i
n Upper Ball Creek, a high-elevation circumneutral stream in North Car
olina (961.0 mg AFDW m(-2) yr(-1), Huryn & Wallace, 1987). This differ
ence 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.
