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...

This investigation was undertaken to verify the prevalence of helminths parasites in the gastrointestinal tract of catfish. A total number of 116 catfish (Silurus glanis) were collected from Zarrine-roud river and examined for helminths. Fish were examined after washing contents of gastrointestinal tract and observed for the presence of helminths using a stereo microscope and a light microscope...

The impacts of invasive species on resident communities are driven by a tangle ecological interactions difficult to quantify empirically. Combining niche model with population dynamic model, both allometrically parametrized, may represent consistent framework investigate in food web context when empirical data scarce. We used this assess the consequences an apex predator ( Silurus glanis ) peri...

Yeryüzünde gerek insan gerekse suda yaşayan organizmaların yaşamlarının devamlılığı açısından temiz su kaynakları giderek azalmaktadır. Tarımsal faaliyetler, sanayi atıkları ve evsel atıklardan kaynaklı gibi birçok kirletici suların kirlenmesine neden olmaktadır. Farklı kaynaklardan sulara karışan toksikantlar nedeniyle sularda organizmalarda çeşitli genetik hasarlar ortaya çıkabilmektedir. Gen...
