Description
Summary:Results obtained with common bream (Abramis brama) originating from the rivers Trent and Sow (Great Britain) are presented with particular attention to the egg size and absolute and relative fecundity recorded during stripping of hormonally (pituitary extract) treated females. The average number of eggs obtained by stripping 1 kg of female biomass (RSF) from the river Sow and Trent were 93,642 ± 20,896 and 151,179 ± 25,123, respectively. These values were similar to the respective parameters in bream populations from north-western USSR lakes.[PUBLICATION ABSTRACT]
