“…Prior to reductions in GST activity, pathways mobilizing body energy stores that assist NADPH regeneration are likely sustaining GSSG-GSH recycling, and consequently GST activity during acute starvation (Andersson 1986;Vigano et al 1993;Kennedy et al 2004). Refeeding of feed-restricted and fasted trout initiated a 69% and 14% increase in GST activity, returning it to baseline levels, a trend also noted in dentex (Dentex dentex) and gilthead seabream (Sparus aurata) (Pascual et al 2003;Morales et al 2004). These results suggest that renewed energy intake provides the energy necessary to restore support mechanisms for this Phase II defence activity (Morales et al 2004).…”

“…These are the aminotransferases that were distributed in liver and plasma whose levels are low when the animal is healthy but high in case of hepatopathy [30,31]. To our knowledge, the liver might not be a target organ for nodavirus and it could not cause hepatic failure [19,26], therefore, it seems that the rise of ALT and AST in infected group could be attributed to the participation of reactive oxygen species generated by long time starvation in liver which caused liver damage [47].…”

Betanoda virus is an emerging problem in several marine fish species in various geographic areas all over the world. In recent years, mullets stock of the Caspian Sea decreased dramatically and a betanoda virus likeagent was introduced as the cause of mullet's mortality. The main objective of the present study is to compare hemato-biochemical parameters in healthy and infected sharpnose mullets (Liza saliens) to betanoda virus likeagent. The adult sharpnose mullets (34 clinically affected fish ? 34 apparently healthy fish) were captured from the southeast the Caspian Sea from 2012 to 2013. All of the captured fish were 4 or 5 years old. The main clinical sings of infected fish were lethargy, severe abdominal distention, abnormal swimming and hyperinflation of swim bladder. The results showed that the weight and total length of infected fish were significantly lower than the healthy fish. The results of histopatological evaluation and indirect florescent antibody test were confirmed the presence of a betanoda virus-like agent in infected fish. The diseased fish were severely anemic (hypochromic macrocytic anemia) and had a serious haemopoietic disorders. The anemia associated with a sever leukopenia, a significant rise of neutrophils and immature neutrophils and a significant decries of lymphocytes percentage. Total protein, albumin and total immunoglobulin levels were significantly reduced in the serum of infected fish, while the activities of aspartate aminotransferase and alanine aminotransferase significantly increased when compared to the healthy fish. These results suggested that the feeding of the infected fish to betanoda virus like-agent were disturbed and it could be cause haemato-biochemical disorder and mortality of the fish in Iranian water of the Caspian Sea.

“…The majority of ROS, which include superoxide (O 2 и-), hydrogen peroxide (H 2 O 2 ) and the hydroxyl radical (иOH) are produced by the electron transport chain during oxidative phosphorylation (Droge, 2002). ROS production increases when electron transfer is disrupted (Turrens, 2003), which can be brought about by a number of conditions, including food deprivation (Pascual et al, 2003), zinc deficiency (Hidalgo et al, 2002), pollutants (Torres et al, 2002), hypoxia (Dirmeier et al, 2002), hyperoxia (Ritola et al, 1999) and changes in temperature (Ali et al, 2010;Heise et al, 2007;Heise et al, 2006;O'Kane et al, 1996).…”

SUMMARYLinkages between cold acclimation and oxidative stress in fishes are unclear and contradictory results have been published. We sought to determine whether oxidative stress occurs during cold acclimation of threespine stickleback (Gasterosteus aculeatus), and, if so, when it occurs and whether it varies among tissues. Fish were warm (20°C) or cold (8°C) acclimated for 9weeks, and harvested during acclimation. Oxidative stress was assessed in oxidative and glycolytic muscles and liver by measuring levels of protein carbonyls and glutathione, and the activity and transcript levels of superoxide dismutase (SOD). Protein carbonyl levels increased in liver after 1week at 8°C and then decreased after week4, and remained unchanged in glycolytic and oxidative muscle. Glutathione levels increased in liver on day3 of cold acclimation and may minimize oxidative stress later during acclimation. When measured at a common temperature, the activity of SOD increased in oxidative and glycolytic muscles on day2 of cold acclimation, and on day3 in liver, and remained elevated in all tissues compared with warm-acclimated animals. When measured at the acclimation temperature, the activity of SOD was significantly higher only at week9 in oxidative muscle of coldacclimated stickleback compared with warm-acclimated fish, and remained constant in glycolytic muscle and liver. Increased SOD activity in oxidative muscle may be required to prevent oxidative stress brought about by increased mitochondrial density. In both muscle and liver, SOD activity increased independently of an increase in transcript level, suggesting post-translational modifications regulate SOD activity.
