Abstract
Length-weight relations (LWRs) and different indices of condition factor for roach from Lake Volvi (Northern Greece) were estimated. Results showed that roach are heavier of a given length in Lake Volvi than in other areas worldwide, with females exhibited higher weight than males of the same length. Significant differences (P<0.05) of LWRs were also exhibited between sexes depending on month. CLARK condition factor peaked at the end of summer displaying no significant difference between sexes, whereas the other three estimated condition factors (Allometric, FULTON, LE CREN) peaked in winter. The estimation of different proxies of condition factor disaggregated by sex might reduce the uncertainty raised by the estimation of fish growth.
对希腊北部Volvi湖地区蟑螂的长权关系(LWRs)和条件因子的不同指标进行了估算。结果表明:在一定长度范围内,沃尔维湖的蜚蠊比世界其他地区的蜚蠊重,相同长度范围内雌蜚蠊比雄蜚蠊重;不同性别、不同月份的lwr也有显著差异(P<0.05)。CLARK条件因子在夏末达到高峰,性别差异不显著,而其他3个条件因子(Allometric, FULTON, LE CREN)在冬季达到高峰。按性别分类的条件因子的不同代用物的估计可以减少鱼类生长估计带来的不确定性。
