Growth rate, catalase and superoxide dismutase activities in rock carp (Procypris rabaudi Tchang) exposed to supersaturated total dissolved gas

Abstract

Liu et al. / J Zhejiang Univ-Sci B (Biomed & Biotechnol) 2011 12(11)Abstract: Total dissolved gas supersaturation (TDGS) appears when the pressures of gases in a solution exceed the barometric pressures. TDGS is often caused by flood discharge at dams. It may lead to gas bubble disease (GBD) for fish and biochemical responses of selected fish and other aquatic organisms. The purpose of this study was to determine the impact of long-term TDGS levels on the growth and biochemical responses of rock carp (Procypris rabaudi Tchang) dwelling in the upper reaches of the Yangtze River. Three-year-old rock carp were exposed to TDGS levels at 100%, 104%, 108%, 112%, and 116% for 42 d. Samples were taken every 7 d after the start of the trial in order to determine catalase (CAT) and superoxide dismutase (SOD) activities in gill and muscle tissues. Samples were taken at Days 0 and 42 of exposure to determine growth rate. Little effect was found on growth rate in all treatment groups. SOD and CAT activities varied in different tissues, according to time of exposure and TDGS levels. The biochemical response of fish exposed to TDGS was more obvious in gill tissue than in muscle tissue. Surveys of SOD and CAT activities in different tissues offer important information about the effect of TDGS on the rare fish in the Yangtze River, and may help evaluate the risk to the aquatic eco-environment and aquatic ecosystem in the downstream of the Yangtze River.

Effects of total dissolved gas supersaturated water on lethality and catalase activity of Chinese sucker (Myxocyprinus asiaticus Bleeker)

“…Gray et al (1985) reported that the 96 h LC 50 values of sea bass and striped mullet were 127.2% and 129.4% respectively at 20 °C. No significant changes of growth rate were found by Liu et al (2011) after rock carp were exposed to gas saturation ranging from 100% to 116% for 42 d, but biochemical responses assessed by catalase (CAT) and superoxide dismutase (SOD) activities were obviously found.…”

Tolerance and Avoidance Behavior towards Gas Supersaturation in Rock Carp Procypris rabaudi with a History of Previous Exposure

“…The high water head and high spill contribute to intense pressure in the deep-plunge pool, causing the high supersaturated TDG (Li et al 2009;Qu et al 2011). Hence, the impact of TDG supersaturation on fish species of the upper Yangtze River is receiving close attention (Huang et al 2010;Liu et al 2011;479 Chen et al 2012;Liang et al 2013). Tolerance to TDGsupersaturated water varies between species, temperature, and life stage (Beeman et al 2003;Smiley et al 2011;Geist et al 2013;Shen et al 2014).…”

Studies of Some Morphological and Biochemical Parameters Concerning the Health Condition of Some Fish Species from Prut River, Romania

“…Natural or anthropic changes in the environment introduce oxidative stress that results in disequilibrium in the cell by increasing the production of ROS [18]. The enzymatic antioxidants, such as superoxide-dismutase, glutathione-peroxidase, catalase and peroxidase, form an important part of the antioxidant response [50].…”
