...vae were investigated in rainbow trout(O. mykiss). The polyunsaturated fatty acids (PUFA) were found the highest followed by monounsaturated fatty acids (MUFA) and saturated fatty acids (SFA) in the unfertilized eggs. On the other hand, PUFA was the highest followed by SFA and MUFA in the semen. The proportions of the some fatty acids, such as C14:0, C16:1n-7, C18:0, C18:1n-9, C18:2n-6, C18:3n-3, C20:2n-6, C20:3n-6, C20:4n-6, C22:6n-3 remained stable fr...

...>Salmo rizeensis and rainbow trout Oncorhynchus mykiss. Different activation media (NaCl, 0.3%; NaHCO3, 1%) were supplemented with L-tryptophan [Control (0), 0.5, 1, 2, 3, 4 and 5 mM] for assessing sperm motility and its duration, fertility and hatching rate of eggs. The results from the present study indicated that addition of L-tryptophan increased the motility rate and duration in O. mykiss, S. rizeensis and S. coruhen...

...er and muscle tissues of rainbow trout (Oncorhynchus mykiss). Eight-days of fasting caused a significant decrease in glucose, total protein, triglyceride, cholesterol, high-density lipoprotein and low-density lipoprotein levels as well as protein and lipid reserves in liver and muscle tissue of fish (p<0.05). The fasting period had no significant effect on the hepatic thiobarbituric acid reactive substances (TBARS), but, it caused a significant decre...

...chitosan coatings on the rainbow trout fillets were evaluated based on the protein profile, bacterial content (total aerobic mesophilic, psychotropic and lactic acid bacteria, Pseudomonas and Enterobacteriaceae), lipid peroxidation (TBARS), total volatile basic nitrogen (TVB-N) and pH values on quality during 12 days. The decrease in bacterial growth activity, physicochemical values (TVB-N, TBARS and pH) and prolonged shelf life in a natural preservativ...

...fficiency in angling for rainbow trout in Karakaya Dam Lake (Malatya, Turkey). Field studies were conducted monthly for a total of 48 fishing operations between May 2013 and April 2014 and again from January 2015 to December 2015. Fishing activities were carried out using fishing gear with three spinner colours (yellow, blue or red), three hook sizes (No. 2: 2 cm; No. 3: 3 cm; or No. 4: 4 cm) and in different seasons (spring, summer, autumn or winter) by three...

In all isolates, cream colored, bright, round and S-type colonies with smooth margins were seen in TSA medium. They were alive during native examination without movement. It was observed that morphologically all isolates were Gram (+), α-hemolytic (BA), oxidase and catalase ne...
