Anesthesia practices in aquaculture are important for preventing potential stress in fish. For this purpose, interest in natural anesthetic agents as substitute for currently used synthetic anesthetics has increased. In this context, the present study demonstrated the anesthetic efficacy of citronella oil (Cymbopogon nardus) in rainbow trout (Oncorhynchus mykiss) individuals. Based on an artificial neural network (ANN) model derived from preliminary studies, the optimal anesthetic concentration for rainbow trout individuals was estimated as 90 μL L−1. Validation of the concentration predicted by ANN revealed no time-dependent hematological or histological effects on fish to citronella oil. Furthermore, biochemical tests revealed that the partial post-anesthesia increase in ALT and AST values was transient and negligible in light of histological findings. Although oxidative stress was observed during the acute period, the enzymatic activity of SOD and CAT effectively reduced the oxidative damage, demonstrating their role in protecting the fish from oxidative stress. The antioxidant activity observed was temporary, returning to baseline levels without any accompanying tissue damage at the tested concentration. Behavioral monitoring further indicated a swift reduction in motor activity followed by a smooth recovery process, with no evident signs of stress or avoidance behaviour. Overall, these results position citronella oil as a promising natural anesthetic for rainbow trout under the studied parameters. That said, further studies involving various solvents, temperature ranges, and fish species are necessary to comprehensively establish its efficacy and safety.

The polychlorinated biphenyls (PCBs) in aquatic environment adversely affect non-target organisms, including fish. Especially, the male reproduction and next generation can be damaged through high exposure to these pollutants. Hence, the sperm cells were exposed to sublethal concentrations of Aroclor 1254 (0, 1, 5, 10, or 25 mg/l) for 4 h. The sperm quality parameters were analyzed by SCA (Sperm Class Analyzer). The fertility, eyeing, and hatching rates were determined as gamete markers. Lipid peroxidation (malondialdehyde-MDA), glutathione (GSH), and antioxidant enzymes [superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT)] were measured for determination of oxidative stress. Our results showed that Aroclor 1254 negatively affected the motility rate and duration, fertilization rate, embryogenesis, and hatching and also triggered antioxidant defense mechanisms at the highest concentration (25 mg L−1). Furthermore, linear speed (VSL), linearity index (LIN), and amplitude lateral head (ALH) were significantly changed after exposure to 25 mg L−1, and the lowest concentrations (1 and 10 mg L−1) did not significantly affect the motility and fertilizing capacity. The embryogenesis and hatching were significantly affected by sperm exposure to 1, 10, and 25 mg L−1 of Aroclor 1254. Consequently, Aroclor 1254 causes potential hazards in male germ cells, and the exposure of sperm cells to pollutants can adversely affect next generation of wild populations.

Özçiçek, Esin; Can, Erkan; Yılmaz, Ökkeş
In this study, fatty acids, fat-soluble vitamins (A, D, E, K vitamins) and cholesterol contents of wild-caught and farm-raised rainbow trout (Oncorhynchus mykiss) were compared. The amounts of docosahexaenoic acid (22:6 n-3, DHA) in wild and farmed forms were 21.56%–18.14%, 18.79%–16.21% and 14.34%–11.49% in April, May and June, respectively. Vitamin E, which is one of the fat-soluble and antioxidant vitamins, showed highest level among the vitamins. Vitamin E levels in both wild and farmed fish were 5.11–4.26, 4.83–2.89 and 0.99–1.95 mg/100 g in April, May and June, respectively. The substantial difference between wild and farmed rainbow trout was found in May (p < 0.05). In conclusion, both wild and farmed rainbow trout from Keban Dam Lake (Pertek Region) can be considered as good sources of n-3 polyunsaturated fatty acids (PUFA). However, it was observed that the n-3 PUFA level in wild form was higher than the culture fish within the investigated monthly periods. On the other hand, farmed fish demonstrated higher levels of n-6 PUFA over the wild individuals.

Akça, Ayşe; Kocabaş, Mehmet; Kutluyer, Filiz
As a widespread pollutant, glyphosate (GLY) adversely affects the aquatic environment and can impair the reproductive ability and functions of fish. The purpose of the current study was to assess in vitro effect of GLY on rainbow trout (Oncorhynchus mykiss) sperm cells. The sperm cells were exposed to different GLY concentrations (2.5, 5, 10 mg/L). Sperm motility parameters were analyzed with computer assisted sperm analysis. DNA fragmentation (%) was measured by the comet assay using fluorescence microscopy. With increased GLY concentration, sperm motility and duration decreased after exposure. DNA fragmentation (% DNA in tail) in sperm cells was higher in treatments containing GLY than control (p < 0.05). Consequently, sperm cells are sensitive to low doses of GLY, and this can negatively affect natural populations.

In this study, alpha and gamma iron oxide nanoparticles, characterizations, toxic effects after being exposed to rainbow trout (Oncorhynchus mykiss) at 0, 1, 10 and 25 mg/L concentrations for 10 days, and then 10-day recovery period without any nanoparticle exposure were examined for histopathological (kidney, liver and gill), hematological, iron accumulation and potential for oxidative stress (TBARS and GSH). Histopathological damages significant at the exposure of increasing concentrations of both nanoparticles (increase in melanomacrophage aggregations, epithelial tissue deformations, cytoplasmic vacuolizations, fatty changes, necrosis, pyknosis, hyperplasia, hypertrophy, lamellar fusions, capillary dilatations). Gamma nanoparticles were determined to accumulate more than the alpha nanoparticles. The most Fe accumulation was detected in the liver. The findings of oxidative stress parameters showed that both nanoparticles have the potential to generate oxidative stress. It was concluded that the exposure of alpha and gamma nanoparticles at specified concentrations and durations had a toxic effect on rainbow trout and the toxicity of these nanoparticles was similar.

The present study was focused on determining the effect of L-tryptophan on quality of sperm and its fertilizing capacity in endangered trout Salmo coruhensis, Anatolian trout 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. coruhensis compared to control group. Highest sperm motility rate and its duration, and fertility and hatching rate of eggs of O. mykiss, S. rizeensis and S. coruhensis were 0.5 mM, 5 mM and 2 mM, respectively. To conclude, sperm quality and fertility were positively affected by quantitative changes different concentrations of L-tryptophan. In addition, L-tryptophan can be used in activation medium for O. mykiss, S. rizeensis and S. coruhensis. Copyright 2018 Zoological Society of Pakistan.

Chemical composition of the essential oil was analyzed by GC-MS, and found to contain the phenol (40.95 %) as major component. Results showed that Y. ruckeri (3 × 107cfu fish-1) infection caused the characteristic symptoms on rainbow trout (petechial hemorrhages on the surface of body and liver). Y. ruckeriinducedinhibitions of Cas-3, Cas-8, p53 and HSP-70. After the administration of thyme essential oil (10 mg kg-1 diet) to infected fish tissues, Cas-3, Cas-8, p53 and HSP-70 mRNAs were up-regulated by 9.31, 9.18, 9.58, and 6,1 fold change, respectively. According to the results of the study, the inhibitions seen all analyzed genes were due to Y. ruckeri infection. However, they were entirely increased by thyme treatment. Thus, targeting pro-apoptotic proteases by agents such as T. vulgaris could improve therapeutic options for infectious disease in fish.

There is limited information on the scientific literature about the effect of in vitro exposure of fish sperm to pesticides. In vitro effect of cypermethrin on sperm quality and oxidative stress has not yet been fully investigated. Therefore, the effects of cypermethrin, a type II pyrethroid insecticide, on quality and oxidative stress of spermatozoa were examined in vitro. To explore the potential in vitro toxicity of cypermethrin, fish spermatozoa were incubated with different concentrations of cypermethrin (1.025, 2.05 and 4.1 mu g/l) for 2 h. The motility rate and duration of sperm were determined after exposure to cypermethrin. Reduced glutathione (GSH), glutathione peroxidase (GSH-Px), catalase (CAT) and malondialdehyde (MDA) in spermatozoa were analyzed for determination of oxidant and antioxidant balance. Our results indicated that spermatozoa motility and duration significantly decreased with exposure to cypermethrin. Additionally, activity of GSH-Px (P < 0.05) and MDA and GSH levels increased in a concentration-dependent manner while CAT activity decreased (P < 0.05). Consequently, the oxidant and antioxidant status and sperm quality were affected by quantitative changes and different concentrations of cypermethrin. (C) 2015 Elsevier Inc. All rights reserved.

There is little information in the scientific literature about effect of in vitro exposure of fish spermatozoa to pesticides. In vitro effect of Lambda-cyhalothrin (La) on sperm quality and oxidative stress has not been fully explored yet. The effects of LCT, which is a synthetic pyrethroid insecticide, on quality and oxidative stress of spermatozoa were investigated in vitro due to extensively use to control a wide range of insect pests in agriculture, public health, and homes and gardens. To explore the potential in vitro toxicity of La, fish spermatozoa were incubated with different concentrations of LCT (0.6, 1.2 and 2.4 mu g/L) for 2 h. Reduced glutathione (GSH), glutathione peroxidase (GSH-Px), catalase (CAT) and malondialdehyde (MDA) in spermatozoa were analyzed for determination of oxidant and antioxidant balance. Our results indicated that the percentage and duration of sperm motility significantly decreased with exposure to LCT. Activity of GSH-Px and MDA (P < 0.05) and GSH levels (P < 0.05) increased in a concentration-dependent manner while CAT activity decreased (P < 0.05). In conclusion, the oxidant and antioxidant status and sperm quality were affected by increasing concentrations of LCT. (C) 2015 Elsevier B.V. All rights reserved.

In present study, it was examined whether addition of different antioxidants to the cryopreservation extenders had an effect on semen post-thaw fertility and motility in rainbow trout (Oncorhynchus mykiss) and also it was investigated the sperm characteristics post-thaw sperm characteristics and fertility. The collected semen was pooled to minimize individual variation. Each pooled ejaculate was split into 12 equal aliquots and diluted with base extenders supplemented with the antioxidants, and a base extender with no additives (control). The pooled semen samples diluted at the ratio of 1:10 by the extenders were subjected to cryopreservation. Antioxidants were separately added to the extenders (one per experimental group): catalase (250 U/l), superoxide dismutase (250 U/l), peroxidase (250 U/l), oxidized glutathione (1.5 mmol/l), reduced glutathione (1.5 mmol/l), L-methionine (1.5 mmol/l), uric acid (0.25 mmol/l), L-ascorbic acid (0.5 mmol/l), alpha-tocopherol (2.0 mmol/l), beta-carotene (0.5 mmol/l) and camitine (0.5 mmol/l). After dilution the semen was aspirated into 0.25 ml straws, the straws were placed on the tray, frozen for 10 min, and plunged into liquid nitrogen. Our results indicated that the post-thaw motility rate increased in extenders supplemented with uric acid, L-methionine, SOD, L-carnitine, alpha-tocopherol and L-reduced glutathione (p < 0.05). The motility duration of frozen thawed semen increased in extenders supplemented with uric acid, L-methionine, SOD, alpha-tocopherol and L-reduced glutathione (p < 0.05). Fertilization rate and hatching rate of frozen-thawed semen was not affected by the tested antioxidants. Consequently, the tested antioxidants affected the motility parameters and cryopreservation extenders could be supplement with antioxidants. This study suggested usage of antioxidants in the cryopreservation of rainbow trout. (C) 2014 Elsevier Inc. All rights reserved.

The fish (84 +/- 1.02 g mean +/- SEM) were divided into 3 groups (N=15 in each group) as control (CNT), infected with Yersinia ruckeri (INF), and infected and essential oils (+EO). The CNT and INF groups were fed only with commercial fish feed. The +EO group was fed with feeds prepared with the rate of 10 ml herbal essential oils (mixed thyme and fennel) / 100 g feed during 21 days. The liver tissue (0.4 g) of fish was dissected in third day of the experimental period and mRNA transcription levels in liver tissue were determined by Real Time PCR analysis. INF and +EO groups exhibited decreased immunity against the challenging with Y. ruckeri infection (53.57 and 42.85 % mortality, respectively) when compared with CNT group (93.33 %). Gene mRNA transcription levels of tumour necrosis factor alpha (TNF-alpha), interleukin 1 beta (IL-1 beta), inducible nitric oxide synthesis (iNOS), serum amyloid A (SAA), that are responsible during the initiation and continuation of the inflammation increased in 1.86, 2.46, 1.62 and 55.7 fold change, respectively in INF group, whereas mRNA expressions of haptoglobin (Hp) decreased (1.2-fold change) in 3th day of experimental period.

The aim of study was to compare the effects of supplementation of food with herbal oils (Thymus vulgaris and Foeniculum vulgare) on biochemical properties and electrolytes of rainbow trout infected with Yersinia ruckeri. In total, 120 healthy fish (mean weight 84 +/- 1.02 g) were equally divided into four experimental groups. The experimental study was carried out for one week. The first group was control without supplementation and infection, the second group was infected and without oil supplementation, the third group was supplemented with oils (10 ml.100 g(-1) rates) for one week and infected with Y ruckeri and the last group was oil supplemented without infection. Results indicated that fish fed with dietary supplements showed enhanced bactericidal activity, total protein, albumin, cholesterol, triglyceride and bilirubin compared to the control (P < 0.05). As the value of herbal oils was increased in diets, the plasma glucose level decreased. The levels of K, Na, Ca, and Mg increased whereas Cl values decreased, compared to the control. It can be concluded that diet supplementation with herb oils used in this study can increase disease resistance by increasing levels of some biochemical parameters and electrolytes in rainbow trout to Y ruckeri infection.

In this study, anesthetic effects of five different concentrations of 2-phenoxyethanol (0.2, 0.3, 0.4, 0.5 and 0.6 ml/L) and clove oil (0.50, 0.75, 1.00, 1.25 and 1.50 ml/L) on rainbow trout (Oncorhynchus mykiss) were studied at temperatures 7, 13 and 18 degrees C. For this purpose, 900 fish (39.08 +/- 1.13 g and 15.48 +/- 0.21 cm) were used in the experiment. Induction time of 2-phenoxyethanol and clove oil varied between 1.05 and 3.36 min at all concentrations, except for 0.2 ml/L (for 2-phenoxyethanol only) and at every temperature application. Full recovery time occurred between 2.44 and 7.14 min for 2-phenoxyethanol and 3.23 - 6.11 min for clove oil. It was found that full recovery times significantly increased with increase in 2-phenoxyethanol concentrations (r(2)=0.81). The same increasing trend was observed in clove oil, but the increase was not strong compared to 2-phenoxyethanol (r(2)=0.21). On the other hand, full induction times of 2-Phenoxyethanol and clove oil significantly declined with the increase in concentrations (r(2)=0.74; r(2)=0.84 for 2-phenoxyethanol and clove oil, respectively). Based on the ideal induction (less than 3 min) and recovery (less than 5 min) time criteria, it can be suggested that the most appropriate concentrations for rainbow trout were 0.3, 0.4 and 0.5 ml/L for 2-phenoxyethanol and 0.50, 0.75 and 1.00 ml/L for clove oil.
