Preliminary studies on the cryopreservation of spermatozoa in the fresh water fish common carp (Cyprinus carpio L.)
Common carp [Cyprinus carpio (C. carpio)] is an economically important fish species cultured mostly in Asia and Europe. Global production of farmed common carp was about 6.14% (3 172 488 tonnes) of the total world aquaculture production[1]. Artificial insemination can be applied to increase the production to meet this demand due to exploitation of natural stocks. Cryopreservation is a valuable ...
متن کاملThe effects of different levels of biogen probiotic additives on growth indices and body composition of juvenile common carp (Cyprinus carpio L.)
An experiment was conducted to evaluate the effects of biogen probiotic additives on growth performance of common carp, Cyprinus carpio. Four practical diets containing 0 (control) , 0.1, 0.2 and 0.3 % Biogen probiotic were used to feed fish. Seventy-two juvenile common carp (65 ? 3.5g) were randomly distributed between 12 fiberglass tanks of 500 L capacity. During 60 days of feeding trial, the...
متن کاملCryopreservation of common carp (Cyprinus carpio) embryos using different cryoprotectant
This study reports that common carp (Cyprinus carpio) embryos were successfully frozen and preserved by vitrification. The modified Haga solution was tested by using two different cryoprotectants and three different concentrations at 4°C to obtain appropriate vitrified solutions ((dimethylsulfoxide 5, 10, 15% (DMSO) and glycerol 5, 10, 15% (gly)) in the study. The hatching rates of embryos exp...
متن کاملGenetic analysis of wild common carp, Cyprinus carpio L. in the Anzali wetland, the Caspian Sea
The Caspian Sea and its basin (e.g. Anzali wetland) is one of the natural habitats of wild common carp Cyprinus carpio. In this study the genetic structure of this species. In the south-west of Caspian Sea (the Anzali wetland) was investigated using PCR-RFLP analysis of D-loop region. Two hundred of mature fish were collected from 5 stations (40 individuals from each station) including Siahkesh...
متن کاملEvaluation of electronarcosis and clove oil for short-term anesthesia in common carp, Cyprinus carpio L. 1758
Anesthesia is considered to be the best way to ensure animal welfare during handling etc. Clove oil and electronarcosis are among the most popular chemical and physical anesthetics used in fisheries and biology; however there is a little information available on the effect of anesthesia using direct electric current in fish. In the present study, the impacts of clove oil (30 mg.l-1) and electro...
