Growth of Wels (silurus Glanis L.) in the Vistula River and the Zegrzyñski Reservoir
The age of wels (Silurus glanis L.) and the back calculated length at subsequent ages were estimated using sections of the first pectoral fins. The growth of this species in the Vistula River follows the von Bertallanfy curve. Some fish grew faster in the Zegrzyñski Reservoir after its inundation in 1962 than they had before. The two populations exhibited an intermediate growth rate which was b...

An increased number of reports (by anglers, in the angling press) of European (wels) catfish Silurus glanis occurrences in the River Thames (England) has led to the perception that the species has become more abundant in that river. If proved true, then this would have ramifications for non-native species policy and practice. To assess catfish density, a total of 256 rod hours of specialized an...
متن کاملInhibitory effect of citric acid on rancidity of frozen catfish (Silurus glanis)fillets
The effect of aqueous solution of citric acid (CA) on the lipid stability of the European catfish (Silurus glanis) fillets during frozen storage (up to 6 months) was investigated. Rancidity development was measured by several biochemical indices (free fatty acids, peroxides and TBA) and complemented by the measurement of expressible moisture and sensory evaluation (flesh odor, consistency and f...
