Effects of transport media and duration on the mortality and physiological responses in silver carp Hypophthalmichthys molitrix fingerlings

Aspects of Embryonic and Larval Development in Bighead Carp Hypophthalmichthys nobilis and Silver Carp Hypophthalmichthys molitrix

As bighead carp Hypophthalmichthysnobilis and silver carp H. molitrix (the bigheaded carps) are poised to enter the Laurentian Great Lakes and potentially damage the region's economically important fishery, information on developmental rates and behaviors of carps is critical to assessing their ability to establish sustainable populations within the Great Lakes basin. In laboratory experiments,...

Effect of chemical herbicides and insecticides on mortality and feeding of silver carp (Hypophthalmichthys molitrix)

Fingerlings of Silver Carp (Hypophthalmichthys molitrix) were used in an ecotoxicological investigation. The fish were exposed to (0.3-10 mg/l) Machete, (3-5 mg/l) Saturn, (1.5-13 mg/l) Diazinon and (1-10 mg/l) Malathion to measure the toxicity effect of these chemicals on mortality, feeding and ingestion rate. Methods for investigation on mortality were according to TRC (1984) and feeding beha...

Evaluation of the Effects of Exposure to Copper Sulfate on some Eco-physiological Parameters in Silver Carp (Hypophthalmichthys molitrix)

Background: Copper is a trace element vital to life, but the toxic effect of water pollution with it on fish is now exhibited. Fish blood is susceptible to contaminationinduced stress and its alternation due to the hematological and immunological parameters can be utilized as toxicity indices of xenobiotics. Methods: In this study, juvenile species of silver carp with average weight of 200gr we...
