Effect of Waterborne Zinc on Survival, Growth, and Feed Intake of Indian Major Carp, Cirrhinus mrigala (Hamilton)

Abstract

The effect of waterborne zinc on survival, growth, and feed intake of Indian major carp, Cirrhinus mrigala (Hamilton), advanced fry was studied under laboratory condition. Survival rates of C. mrigala advanced fry (2.71±0.49 g) after 30 days exposure to control (0.01), 0.03, 0.06, 0.10, and 0.15 mg/L zinc using the static renewal method in freshwater at pH 7.3±0.2, temperature 26±2°C, and total hardness 114±16 mg/L as CaCO 3 were 100%. Growth of the fish exposed to 0.10 and 0.15 mg/L of zinc was significantly lower (P<0.05) than in control (0.01), 0.03, and 0.06 mg/L of zinc after 30 days of exposure. However, there were no significant differences (P>0.05) in fish growth between 0.03 and 0.06 mg/L zinc concentrations. Feed intake rates were significantly (P<0.05) reduced in the fish exposed to 0.10 mg/L and higher levels of zinc. The zinc accumulation in the whole body of the fish increased with increasing concentrations of the metal.

Growth, biochemical variables, and zinc bioaccumulation in Nile tilapia, Oreochromis niloticus (L.) as affected by water-born zinc toxicity and exposure period

“…Furthermore, changes in protein and lipid contents in fish body may be linked with changes in their synthesis and/or deposition rate in fish body (Fauconneau 1985;Abdel-Tawwab et al 2006), or because fish exerted more energy to challenge the Zn toxicity effect. Similar results were obtained by Mohanty et al (2009) who concluded that Zn accumulation in the whole body of Indian major carp increased with increasing Zn concentration. Abdel-Tawwab et al (2012) and(2013) found that Zn accumulations in the whole bodies of Nile tilapia and common carp are correlated with Zn concentrations.…”

“…An alternative hypothesis is that due to the reduced feed intake, the required energy to cope Zn toxicity stress was met via the decomposition of the storage‐deposited nutrients. Similar results were obtained by Mohanty, Adhikari, Mohanty, and Sarangi () who concluded that the culture of Indian major carp, Cirrhinus mrigala , in an environment containing more than 0.06 mg Zn/L could significantly lower their growth and feed intake.

“…An alternative hypothesis is that due to the reduced feed intake, the required energy to cope Zn toxicity stress was met via the decomposition of the storagedeposited nutrients. Similar results were obtained by Mohanty, Adhikari, Mohanty, and Sarangi (2009) reflect the loss of protein and lipid levels in the Zn-exposed fish, which may be due to increased protein oxidation with Zn exposure (Cakmak, Dogan, & Severcan, 2006;Takahashi, French, & Wong, 1991) and/or the use of those molecules as energetic substrates to cope with stress metabolically (Vijayan, Cristina Pereira, Grau, & Iwama, 1997). Similar results were found with Nile tilapia (Abdel-Tawwab, 2016;Abdel-Tawwab et al, 2012, 2016 and common carp (Abdel-Tawwab et al, 2013) exposed to waterborne Zn toxicity.…”

Effects of dietary zinc on the growth, digestive enzyme activities, muscle biochemical compositions, and antioxidant status of the giant freshwater prawn Macrobrachium rosenbergii

“…Similarly, Satoh et al (1987) reported that Zn deficiency leads to slow growth and increased mortality in fish. An excess of dietary Zn suppressing survival and growth have also been reported in C. auratus, P. monodon, I. punctatus, Cyprinus carpio, Cirrhinus mrigala, and E. sinensis (Gatlin and Wilson, 1983;Jeng and Sun, 1981;Mohanty et al, 2009;Rani et al, 2012;Shiau and Jiang, 2006;Tan et al, 2011).…”
