Subacute Toxicity Effects of Deltamethrin on Oxidative Stress Markers in Rainbow Trout.

Deltamethrin is a pyrethroid insecticide that is considered extremely toxic to aquatic organisms. We evaluated the effect of subacute doses (0.033, 0.

Oxidative stress and related biomarkers in cupric and cuprous chloride-treated rainbow trout.

We examined the time-course stress responses in the liver of rainbow trout exposed to cuprous chloride (CuCl) and cupric chloride (CuCl). The treatment groups received a single intraperitoneal injection of CuCl or CuCl (both at a dose of 0.01 and 0.

Prevalence of Diphyllobothrium latum (Cestoda: Diphyllobothriidae) plerocercoids in fish species from four Italian lakes and risk for the consumers.

In recent years there has been a re-emergence of diphyllobothriasis by Diphyllobothrium latum (Cestoda: Diphyllobothriidae) in Italy, France and Switzerland, where in the past this fish-borne zoonosis was widespread and then virtually disappeared. A change in eating habits such as the consumption of raw/undercooked freshwater fish, has led to an increased risk for consumers of ingesting infective larvae of D. latum.

Antioxidant biomarker survey ensuing long-term selenium withdrawal in Acipenser baeri fed Se-cysteine diets.

Two selenium withdrawal periods, 30 and 90 days, were considered for sturgeon fed 90 days three Se-cysteine diets (1.25, 5, 20 mgkg(-1)). Subsequently Acipenser baeri was fed the previous control diet (0.
