Effects of pollution on chub in the River Elbe, Czech Republic
Ecotoxicology and Environmental Safety, 2009 The Elbe River is one of the most polluted aquatic ecosystems in the Czech Republic. The effect of three major chemical plants located on the Elbe River (at Pardubice, Neratovice, and Usti nad Labem) on fish was studied in 2004. Health status, chemical concentrations (Hg, PCB, DDT, HCH, HCB, OCS, 4-tert-nonylphenols, 4-tert-octylphenol) in muscle, and ...

Effect of Bleeding on Lipid Oxidation in the Chub Mackerel Muscle
Bioscience, Biotechnology, and Biochemistry, 2008 Chub mackerel samples were prepared by two different methods of killing, struggling death in iced sea water (control) and instant death by mechanical bleeding (bleeding). The malonaldehyde content in the muscles of the bleeding sample were significantly higher than those of the control after 119 h of storage at 0 degrees C.
