  The profile of fatty acids in the gametes of brook trout (Salvelinus fontinalis) ofduring the spawning period under culture conditions

  The fertilization and subsequently embryo and larvae development are linked to gamete quality and FA (fatty acid) content is one of the specific factors affecting egg or sperm quality. Hence, FA profile of gametes (egg and sperm) was documented in brook trout (Salvelinus fontinalis) under cultivation. FAs were detected and measured using gas chromatography. These results indicated that a total of 26 and 22 FAs were determined in egg and sperm, respectively. The levels of PUFAs were determined in nearly identical quantities in both egg (47.57%) and sperm (47.53%). DHA (Docosahexaenoic acid), LA (Linoleic acid), EPA (Eicosapentaenoic acid) and ARA (Arachidonic acid) were predominant PUFAs for egg and sperm. Interestingly, vaccenic acid (C18:1 n-11) (24.07%) was major FAs in egg. In conclusion, the analysis of fatty acids in broodstock gametes contributes valuable insights into the dietary requirements necessary for effective aquaculture breeding programs.

  The fertilization and subsequently embryo and larvae development are linked to gamete quality and FA (fatty acid) content is one of the specific factors affecting egg or sperm quality. Hence, FA profile of gametes (egg and sperm) was documented in brook trout (Sa lve linus fontinalis) under cultivation. FAs were detected and measured using gas chromatography. These results indicated that a total of 26 and 22 FAs were determined in egg and sperm, respectively. The levels of PUFAs were determined in nearly identical quantities in both egg (47.57%) and sperm (47.53%). DHA (Docosahexaenoic acid), LA (Linoleic acid), EPA (Eicosapentaenoic acid) and ARA (Arachidon ic acid) were predominant PUFAs for egg and sperm. Interestingly, vaccenic acid (C18:1 n-11) (24.07%) was major FAs in egg. In conclusion, the analysis of fatty acids in broodstock gametes contributes valuable insights into the dietary requirements necessary for effective aquaculture breeding programs.

  Spermatologic characteristics and sperm motility alterations caused by short-term copper exposure in Brook Trout Salvelinus fontinalis

  Kutluyer, Filiz; Kocabaş, Mehmet; Başçınar, Nadir

  Spermatozoa movement in many aquatic animals with external fertilization is directly related to the external aqueous environment. In particular, environmental toxic metals can cause harmful effects and impair sperm cell functions. The high concentrations of copper (Cu) may be harmful for aquatic animals, while low levels are required for metabolic interactions. Herein, we investigated the effect of different copper concentration [0 mg L−1 (Control),.5 mg L−1, 1 mg L–1, and 2 mg L−1] on spermatozoa of brook trout Salvelinus fontinalis. Motility and survival of sperm cells were assessed. Our results indicated that Cu exposure caused to an evident decrease in motility and longevity of spermatozoa with increasing concentrations (p <.05). Overall, we showed that Cu exposure can impair sperm motility of S. fontinalis. Our study suggested that sperm motility has the potential to be a sensitive bioindicator of freshwater environmental pollution.

  Comparison of Hatching Performances and Yolk Sac Absorptions of Black Sea Trout (Salmo trutta labrax Pallas, 1811), Brook Trout (Salvelinus fontinalis Mitchill, 1814) and Their Hybrid

  Basçinar, Nadir; Kocabas, Mehmet; Sahin, Sebnem Atasaral; Okumus, Ibrahim

  The aims of this study were to determine hatching performance, body and yolk weight at hatching, the growth rate during the yolk absorption and yolk conversion efficiency of Black Sea trout, brook trout and their hybrid larvae, and to compare the relationships between length, total wet weight, dry yolk body weights of alevins and degree-days. The Black Sea trout egg has shorter incubation duration than brook trout and their hybrid. Survival from fertilization to swim-up of brook trout, Black Sea trout, and hybrid were 45.8%, 54.3% and 30.7%, respectively. Length, total wet weight, dry larva weights, and dry yolk weights of brook trout, Black Sea trout and hybrid exhibited a linear relationship with degree-days; dry yolk weight decreased, while length, total wet weight and dry body weight increased with degree-days. The linear regression parameters excluding length slope were significantly different. Length and weight increase as well as growth rates, daily yolk sac consumption and yolk sac efficiency values were calculated as 0.21 mm/day, 0.63 mg/day, 0.30 mg/day, and 0.61 for brook trout; 0.19 mm/day, 0.87 mg/day, 0.60 mg/day, and 0.76 for Black Sea trout, and 0.20 mm/day, 0.45 mg/day, 0.28 mg/day, and 0.46 for hybrid, respectively.

  Effect of Duo-Culture on Growth Performance of Brook Trout (Salvelinus fontinalis Mitchill, 1814) and Black Sea Trout (Salmo trutta labrax Pallas, 1811) in Tank Reared Condition

  Basçinar, Nadir; Sahin, Sebnem Atasaral; Kocabas, Mehmet

  The objectives of the present study were to compare growth performance and feed conversion ratios of brook trout (Salvelinus fontinalis) and Black Sea trout (Salmo trutta labrax) in monoculture and duo-culture tank reared conditions. The fish were about 9-month-old hatchery reared brook trout and Black Sea trout with initial weights of 24.18 +/- 0.64 (n=60) and 23.87 +/- 1.11 (n=60) g, respectively. Fish were kept in 0.2 m(3) fiberglass tanks. Nine tanks were used and the fish were equally allotted to 3 groups with tree replicates and fed for 240 days. Each tank contained 20 fish from each species for monoculture and 10+10 fish from each species for duo-culture. At the end of the study, mean live weights of brook trout and Black Sea trout increased to 265.47 +/- 17.25 g and 206.18 +/- 2.95 g in monoculture. 235.53 +/- 10.25 g and 222.47 +/- 1429 g in duo-culture, respectively, and significant differences were found among the groups (P<0.01). The highest and lowest specific growth rates were found in brook trout and Black Sea trout in monoculture (P<0.01), respectively. The highest and lowest final condition factors were calculated in duo-culture for brook trout and in monoculture for Black Sea trout (P<0.01), respectively. The feed conversion ratio (FCR) for Black Sea trout was higher than it was for the other groups (P < 0.01).
