We report the presence of the parasitic copepod Ergasilus mosulensis Rahemo, 1982 (Copepoda, Ergasilidae) on the Caspian sheaya, Chalcalburnus mossulensis (Heckel, 1843) (Teleostei, Cyprinidae), caught from Atatürk Dam Lake (360 41' N 370 49' E, Sanliurfa, Turkey) between July and August 2006. A total of 23 Ergasilus mosulensis Rahemo, 1982 (Ergasilidae) were recorded from the gills of this fis...

Abstract Laminarin is a source of immunostimulants and antioxidative biomolecules involved in supporting the performance health aquatic animals. Hence, this study investigated growth performance, intestinal morphology, blood biomarkers, immune response Thinlip Grey Mullet ( Liza ramada ) fed dietary laminarin. For 60 days, mullets were diets supplemented with laminarin at 0, 200, 400, 600, 800 ...

Outbreaks causing mass mortalities have been observed in the golden grey mullet (Liza auratus) population in southern coastal area of the Caspian Sea since 2002. The clinical signs include neurological abnormalities, such as erratic swimming behavior, spiral swimming, belly-up at rest and over inflation of the swim bladder. Three hundred and twelve samples of moribund fish with sizes that range...

This study evaluated the toxicity of dispersant application which is, in nearshore area, a controversial response technique to oil spill. Through an experimental approach with juveniles of Liza aurata, the toxicity of five exposure conditions was evaluated: (i) a chemically dispersed oil simulating dispersant application; (ii) a single dispersant as an internal control of chemically dispersed o...

Fish eyes and brain are highly susceptible to environmental Hg exposure but this issue is still scarcely investigated, mainly regarding methylmercury (MeHg) accumulation. Yet, Hg levels in fish lens have not been previously examined under field conditions. Total Hg (tHg), MeHg and inorganic Hg (iHg) levels were assessed in the brain, eye wall and lens of the golden grey mullet (Liza aurata) fro...

High dietary nitrate and nitrite intake may increase the risk of gastro-intestinal cancers due to the In vivo formation of carcinogenic chemicals known as N-nitroso compounds. In this study nitrate and nitrite residues in smoked Caspian kutum, Rutilus frisii kutum and mullet, liza auratus in the local markets (considered as batch no. 1, 2 and 3) of north of Iran were determined using Spectropho...
