“…The effects of low pH and inorganic aluminium on S. salar have been studied in detail in northern Europe where acidification results in chronic (year-round) low pH (Nyberg et al, 1995;Staurnes et al, 1995Staurnes et al, , 1996Kroglund & Staurnes, 1999;Kroglund et al, 2001;Ytrestoyl et al, 2001;Bjerknes et al, 2003) which has resulted in extirpation of S. salar in >25 Norwegian rivers (Hesthagen & Hansen, 1991). Research has also found that S. salar smolts are more sensitive to acidic conditions than other life stages, and this sensitivity appears to increase as the parrsmolt transformation progresses (Staurnes et al, 1993(Staurnes et al, , 1996Monette & McCormick, 2008).…”

The physiological effects of episodic pH fluctuations on Atlantic salmon Salmo salar smolts in eastern Maine, U.S.A., were investigated. During this study, S. salar smolts were exposed to ambient stream-water chemistry conditions at nine sites in four catchments for 3 and 6 day intervals during the spring S. salar smolt migration period. Plasma chloride, plasma glucose, gill aluminium and gill Na + -and K + -ATPase levels in S. salar smolts were assessed in relation to ambient stream-water chemistry during this migration period. Changes in both plasma chloride and plasma glucose levels of S. salar smolts were strongly correlated with stream pH, and S. salar smolt mortality occurred in one study site with ambient stream pH between 5·6 and 5·8 during the study period. The findings from this study suggest that physiological effects on S. salar smolts are strongly correlated with stream pH and that in rivers and streams with low dissolved organic carbon (DOC) concentrations the threshold for physiological effects and mortality probably occurs at a higher pH and shorter exposure period than in rivers with higher DOC. Additionally, whenever an acidification event in which pH drops below 5·9 coincides with S. salar smolt migration in eastern Maine rivers, there is potential for a significant reduction in plasma ions of S. salar smolts.

“…Swimming performance of fish was selected as biomarker since it has obvious reflexes under stress and environmental challenges. Significant changes in fish swimming behaviour were usually apparent in toxicity studies (Gossum, Bots, Snijkers, Meyer, Wassenbergh, Coen & Bruyn ; Mathur & Guo ; Sárria, Soares, Vieira, Castro, Santos & Monteiro ; Ytrestøyl, Finstad & Mckinley ). Environmental factors and disease treatment had been reported to affect fish swimming activity (Israeli & Kimmel ; Bjorge, Nordgreen, Janczak, Poppe, Ranheim & Horsberg ; Roques, Abbink, Chereau, Fourneyron, Spanings, Burggraaf, Van de Bos, Van de Vis & Flik ).…”

This study examined the effect of Aeromonas salmonicida infection on the swimming behaviour and physiology of Atlantic salmon (Salmo salar L.). Fish were injected in the dorsal muscle with either 100 lL bacterium solution (3.05 9 10 7 CFU mL À1 ) Aeromonas salmonicida, or 100 lL 0.9% NaCl (as control group). Compared with the control group, the pathogen injected group significantly impaired the critical swimming speed (U crit ) and exhausting time (P < 0.05), which were reduced by 37% and 39% at severe time (day 6, when most of the fish challenged by Aeromonas salmonicida died) respectively. Furthermore, the blood parameters related to their swimming behaviour were also influenced significantly by pathogen injection (P < 0.05). The results showed that the high density lipoprotein (HDL), haemoglobin and total protein decreased by about 63%, 49% and 74% at the end, respectively, while lactate increased by about 29% on day 6. The results suggested that the swimming performance of Atlantic salmon might be a useful indicator of disease, and it was feasible to warn the outbreaks of acute disease by fish behaviour.

“…Blood glucose level increases on application of various stressors like chemical dichlorodiphenyldichloroethane (Benguira, Leblond, Weber & Hontela 2002) in rainbow trout and high aluminum concentrations (Ytrestøyl, Finstad & Mckinley 2001) in Atlantic salmon ( Salmo salar ). In our findings, the blood glucose level was significantly ( P <0.05) influenced by the addition of dietary pyridoxine in the diet of L. rohita fingerlings.…”

A 60-day experiment was carried out to delineate stress mitigating and immunomodulatory role of dietary pyridoxine (PN) in Labeo rohita ¢ngerlings exposed to endosulfan. Two hundred and seventy ¢ngerlings were randomly distributed into six treatments in triplicates. Five iso-caloric and iso-nitrogenous puri¢ed diets were prepared with graded levels of pyridoxine. Six treatment groups were T 0 (10 mg PN1without endosulfan),T 1 (0 mg PN1endosulfan), T 2 (10 mg PN1endosulfan), T 3 (50 mg PN1 endosulfan), T 4 (100 mg PN1endosulfan) and T 5 (200 mg PN1endosulfan). The role of pyridoxine on stress mitigation and immunomodulation was assessed by biochemical and haemato-immunological parameters like aspartate aminotransaminase, alanine aminotransaminase, lactate dehydrogenase, malate dehydrogenase, superoxide dismutase and catalase were signi¢cantly (Po0.05) lower while acetylcholinesterase was signi¢cantly (Po0.05) higher in pyridoxine-fed groups. Erythrocytes count, haemoglobin content and total serum protein, albumin, globulin, nitroblue tetrazolium and lysozyme activity were signi¢cantly (Po0.05) higher while cortisol and blood glucose were decreased signi¢cantly (Po0.05) in pyridoxine-fed groups. Percentage survival after challenge with Aeromonas hydrophila was highest in T 0 group. The results obtained in present study indicate that dietary pyridoxine supplementation at 100 mg PN kg À 1 diet reduces the endosulfan-induced stress and triggers immune response in L. rohita ¢ngerlings.
