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...

Without sustainable rehabilitation measures, the Lobau, a freshwater Biosphere Reserve, will soon became a primarily terrestrial ecosystem with major implications for its rich aquatic and amphibic biodiversity. An innovative ecosystem management scheme for this Danube floodplain needs to optimally balance between conservation and restoration objectives and to harmonize the partly competing ecol...

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...

BACKGROUND In ectothermal animals such as fish, -temperature affects physiological and metabolic processes. This includes sensory organs such as the auditory system. The reported effects of temperature on hearing in eurythermal otophysines are contradictory. We therefore investigated the effect on the auditory system in species representing two different orders. METHODOLOGY/PRINCIPAL FINDINGS...

The concentrations of iron, lead, cadmium, copper, manganese, mercury and arsenic were measured in water, sediment, five macrophytes (Typha angustifolia, Iris pseudacorus, Polygonum amphybium, Myriophyllum spicatum and Lemna gibba) and five fish species (Sander lucioperca, Abramis brama, Carassius gibelio, Silurus glanis and Arystichtys nobilis) in the Gruža Reservoir, used for water supply and...

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...

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...
