Our aim was to investigate the survival rate at the hatching and yolk sac stage of close-rearing and crossbred rainbow trout population (Erzurum female X Erzurum male - E_F x E_M; Erzurum female X Silifke male - E_F x S_M; Silifke female X Silifke male - S_F x S_M; Silifke female X Erzurum male - S_F x E_M). A total of 32,976 eggs were incubated, 29,012 of which hatched. The survival rate of the larvae was 88%. The insemination rate, brooding yield and hatching rate of E_F x E_M, E_F x S_M, S_F x S_M and S_F x E_M were …

D1, D2 and D3 diets containing 15.5, 12.5 and 9.0 MJ kg^{-1} digestible energy concentrations were offered to rainbow trout (Oncorhynchus mykiss Walbaum, 1792), and the rates of gastric evacuation and feed intake were determined. Gastric evacuation determinations were achieved by slaughtering eight fish every 6 h until no residue was found in the cardiac stomach. Return of appetite experiments were conducted by re-feeding groups of trout every 6 h following the first feeding. The data provided from each process was modelled by regression analysis and compared statistically. Square root equations best explained the gastric evacuation data, whereas first-order models …

The aim of this study was to determine the effect on non-specific defence mechanisms in rainbow trout (Oncorhynchus mykiss) fed diets containing different doses of \beta-glucan (MacroGard), Schizosaccharomyces pombe and S. pombe P450. Over a period of 3 weeks, fish were given 0.1% and 1% MacroGard, 0.1% and 1% S. pombe, 0.1% and 1 % S. pombe P450 in their food. Then phagocytosis, intracellular and extracellular respiratory burst activity, total protein, and specific growth ratio and condition factor values were determined. After feeding for 3 weeks with three different immunostimulants, extracellular and intracellular respiratory burst and phagocytic activity were significantly …

The Effect Of Rainbow Trout (Oncorhynchus Mykiss Walbaum, 1792) Cage Culture On Benthic Macrofauna In Kesikköprü Dam Lake*, İlknur Karaca, Serap Pulatsü
Turkish Journal of Veterinary & Animal Sciences
The aim of this research was to determine the effect of a cage farm with a capacity of about 55 t on the benthic macrofauna in Kesikköprü Dam Lake. At 3 stations (the cage and 15 m and 60 m from the cage) selected for this purpose the abundance and composition of benthic macrofauna were determined for 11 months. The abundance of benthic macrofauna (individuals/m^2) between the stations was statistically significant (P < 0.05). The abundance of benthic macrofauna was higher at the cage station than at the other 2 stations, except in April and November. During the research period the lowest number of individuals (937 individuals/m^2) was found at the second station 15 m from the cage in February; and the highest number (14,091 individuals/m^2) was determined at the cage station in December. Members of the class Pelecypoda were found at all 3 stations. Dreissena, which is a member of the class Pelecypoda, was the most dominant benthic organism (54%), followed by Chrinomus (30%) and Tubifex (11%). At the cage station, while members of the class Pelecypoda were found, no members of the classes Insecta, Oligocheta or Crustacea were found. The highest number of benthic macrofauna genera (7) was found at the station 60 m from the cage in April and November. The lowest number of genera (1) was found at the cage station in July. The results of this study in Kesikköprü Dam Lake reveal that the cage culture has a localizing effect on the abundance and composition of benthic macrofauna.

At the end of the spawning season, semen was collected without anesthesia by abdominal massage from 37 rainbow trout according to different age groups. In collected semens, color, volume, motility, activity time (duration of motility), concentration, total spermatozoa and pH were recorded. Furthermore, body weight and body length were measured and correlations beetween spermatological properties and these parameters were assessed. In the 1-2 years age group, volume (ml), motility (%), activity time (s), concentration (x 10^9 sp/ml), total spermatozoa (per ejaculate) and pH were 9.7, 81.0, 79.0, 8.97, 87.0 and 7.20 respectively; in the 2-3 years age group, these values …

The pharmacokinetics of oxytetracycline (OTC) were investigated in rainbow trout in freshwater at 10.5 ^oC. A group of 70 fish received OTC, an intravascular injection (i.v.) of 5 mg/kg body weight. Another group of 105 fish were fed medicated feed containing a dose of 100 mg/kg body weight. OTC plasma concentrations were determined by high performance liquid chromatography. The pharmacokinetic parameters were described by a two-compartment open model giving distribution half-lives of 0.907 h and 16.058 h, and elimination half-lives of 33.5 h and 27 h for i.v. and oral administration of OTC, respectively. After i.v. administration of OTC, other …

The Characterization Of Protein Profiles Of The Aeromonas Hydrophila And A. Caviae Strains Isolated From Gull And Rainbow Trout Feces By Sds-Page, Hani̇fi̇ Körkoca, Banur Boynukara
Turkish Journal of Veterinary & Animal Sciences
Ten motile Aeromonads, including one Aeromonas hydrophila ATCC 7512, were used. Of the strains, five were isolated from gulls (one A. hydrophila strain and four A. caviae strains) and four from rainbow trout (three A. hydrophila strains and one A. caviae strain). Whole cell protein profiles of these strains were analyzed by SDS-PAGE. Forty-five pairs were formed in comparing the protein profiles of each strain. Of the pairs, 17 (37.8%) were different, 18 (40%) were unclear and 10 (22.2%) were identical. When the strains belonging to the same species were compared within themselves, four A. caviae strains were found to …
Alterations In Hematological Parameters Of Rainbow Trout (Oncorhynchus Mykiss) Exposed To Mancozeb, Muhammed Atamanalp, Telat Yanik
Alterations In Hematological Parameters Of Rainbow Trout (Oncorhynchus Mykiss) Exposed To Mancozeb, Muhammed Atamanalp, Telat Yanik
Turkish Journal of Veterinary & Animal Sciences
Rainbow trout reared in fresh water were exposed to a sublethal concentration of mancozeb (1/2 of LC_{50} = 1.1 mg/l) at 24 h intervals, for 3 weeks in tanks containing 780 l water under natural light conditions with a constant flow (1.5 l min^{-1}) of aerated dechlorinated tap water at 9-11 °C and with no recirculation. Approximately 2 cc venous blood was drawn from each subject (after weekly exposure) for the determination of hematological parameters, using heparin as an anticoagulant. Hematological parameters were investigated weekly. The findings of this study showed that mancozeb had some effect on the hematological parameters …
