1839) in Almus Dam Lake (Tokat, Turkey)]]>KARATAMehmet CANM. Fatih9200589Growth, mortality and yield of Barbel, Barbus plebejus, in Almus Dam
Lake (Turkey) were studied. A total of 201 specimens were collected from January
2003 to December 2003. The total length ranged from 15.2 to 41.5 (TL) cm and
total weight ranged from 33.7 to 816.5 g. Sex ratio (1: 1.83) was biased towards
females (p<0.05). A negative allometric growth was determined in population
(p<0.05). The length-weight relationships for all individuals was described
by the following parameters: a = 0.036, b = 2.60 with the R2 = 0.83.
The population comprised of ten age groups (I to X years). The von Bertalanffy
growth parameters for the entire population were: L8= 45.65±1.72 cm,
k = 0.249±0.023 1/year and to = -0.711±0.102 year (R2 =
0.89). The growth performance index was 2.71. The mortality rates for whole
population were found to be; Z = 0.76 1/year, M = 0.50 1/year and F= 0.26
1/year; and the exploitation rate was E = 0.34 1/year. The Bevarton and Holt
model of yield and biomass per-recruit indicated that the stock of B.
plebejus in the Almus Dam Lake is not over fished (Emax = 0.92, E0.1
= 0.80 and E0.5 = 0.38).]]>Geldiay, R. and S. Balik,1996pp: 265-267pp: 265-267Coad, B.W.,199529164Bianco, P.G.,1995Barbus sp.
