RETRACTED: Detection of LC50 of crude oil in silver carp (Hypophthalmicthys molitrix), common carp (Cyprinus carpio) and Caspian roach (Rutilus rutilus caspicus)

Abstract

The aims of the present study are to investigate acute effects of crude oil as potential dangerous additives to assess mortality effects of these petroleum products on some main cultured fish of Iran. Silver carp, common carp and roach were exposed to the crude oil (0, 2, 5, 10, 20 and 40 ppm). The median lethal concentration (LC50) was determined with probit analysis. The 96 h toxicity tests showed 100% mortality in 40 ppm, and no mortality in 5 ppm for all species. As can be found, LC50 of crude oil in common carp (22.4 ppm) was higher than other species, however silver carp (16.7 ppm) had the lowest one. AC.
