Parasitic infestations constitute an important part of aquatic animal diseases. In order to study the prevalence of parasitic skin infections of rainbow trouts in mordad of 1385, 5 breeding farms were selected and 386 rainbow trouts with the body weight of 250-300 gr we More

Parasitic infestations constitute an important part of aquatic animal diseases. In order to study the prevalence of parasitic skin infections of rainbow trouts in mordad of 1385, 5 breeding farms were selected and 386 rainbow trouts with the body weight of 250-300 gr were collected randomly from each farm and examined. Of the 1930 examined specimens of 5 farms in this study, 14 were infected by Ichthyophthirius sp. (0.7%), 890 by Trichodina sp. (46.1%), 41 by Dactylogyrus sp. (2.1%), 111 by Gyrodactylus sp. (508%) and 874 were without any parasitic infections (45.3%). The highest infection rate belonged to Trichodina sp. Manuscript profile

This study was designed to investigate the influence of supplementing multi-enzyme in feed on growth and survival rate of rainbow trout fish. The multi-enzyme were incorporated into a commercial pellet ration to constitute three experimental diets containing 500, 1000, 1500 gram kemin phytase multi-enzyme per one ton feed intake, while a fourth diet without the multi-enzyme supplement served as the control diet. The diets were offered to rainbow trout (150 g average weight) in quadruplicate pools (each treatment) for 40 days. Fish were sampled at 10, 20, 30 and 40 days after commencement of the feeding trial to determine feed conversion ratio (FCR), weight and length rate and survival rate. Results of our study indicated that effect of different supplementing multi-enzyme levels on feed conversion ratio (FCR), weight and length rate and survival rate, there was not any meaning relation in dose rates (p>0.05). According to affect of type and concentrates of enzyme on animal response, we can recommend that type or concentrates of consummated kemin- phytase multi-enzyme is not suitable for rainbow trout.
