“…The other reason might perhaps be due to less extensive blood circulation in the muscles than other vital tissues such as liver, kidneys and gills. Also muscle is a less metabolically active tissue (Adhikari et al 2009;Wagner and Boman 2003;Radhakrishnan 2010). Even though the skin is a boundary tissue, the accumulation of metals is not so high as noticed in the gills, perhaps due to continuous elaboration and sloughing of slime from the body surface (Singh and Banerjee 2008) causing loss of metals bound with -SH groups of the slime.…”

The aim of this study was to investigate the potential impact of effluent released during metals extraction from polymetallic sea nodules at the Pilot Plant at National Metallurgical Laboratory, India, by analysing different metal (Mn, Cu, Zn, Fe, Pb and Cr) concentrations in six tissues (skin, muscles, gills, liver, kidney and brain) of the fish Labeo rohita. Of the six analysed tissues of seanodule-effluent-exposed fish, liver accumulated highest concentration of most of the metals (2.91-287.36 mg kg -1 ) while muscles (2.1-81.14 mg kg -1 ) lowest. While the concentration of Fe was maximum (60.41-218.7 mg kg -1 ) in all the tissue systems (except muscles and liver), Pb was minimum (0.8-2.91 mg kg -1 ). Accumulation of most of the metals in all the tissues was above the safe limits as recommended by Food and Agricultural Organisation that indicate metal's potential hazardous impact on the fish. High bioaccumulation factors for these metals in the different tissues revealed that metals were extensively bio accumulated and bio concentrated. The time-dependent variation in metal pollution index illustrated increase in gross metal load (p \ 0.05) in different tissue components with increase in exposure period. In conclusion, the sea nodule effluent was found to cause adverse health impact on the fish which in turn might also affect the human health when consumed.

“…A sudden but remarkable development in the field of science and technology and agriculture due to the recent industrial revolution has lead to the disposal of untreated (raw) or partially treated effluents and industrial wastes into aquatic ecosystem. Abrupt increase in the human population has greatly contributed towards discharge of large amount of unused /waste chemical/toxic compounds and other similar pollutants into the environment which has converted fresh water bodies like rivers, lakes and tanks to impending contamination sinks giving rise to water pollution problems (Venkatesan, 2007; [1] ) (Adhikari et al, 2009. [2] ).…”

“…The metabolic behavior, breeding and growth potentials of organisms are significantly affected by the interactions among aquatic organisms and the nature of exposed toxicants (Adhikari et al, 2009). Fish growth, therefore, represents a high degree of variations for metallic ions toxicity and serves as a subtle indicator to monitor stress of environment that could offer invaluable evidence regarding toxicity of metals .…”

To cite this paper: Javed, M., 2015. Growth and metals depuration in Zn+Pb+Ni mixture stressed fish grown under composite pond culture conditions. Int. J. Agric AbstractThe growth performance and metals depuration abilities of Zn+Pb+Ni stressed five fish species viz. Cirrhina mrigala, Hypophthalmichthys molitrix, Labeo rohita, Ctenopharyngodon idella and Catla catla were studied under composite pond culture conditions. All fish species were stressed with metals mixture at their 1/3 rd LC 50 for one month. After stress, the fish were grown in ponds under composite culture conditions for 120 days to realize their growth and metals depuration potentials when grown in stress-free environment. Among treated fish, C. mrigala exhibited significantly better growth, followed by L. rohita, C. idella, H. molitrix and C. catla while growth in control fish followed the order: C. catla ≥ L. rohita > C. mrigala > C. idella > H. molitrix. Both control and treated fish species displayed significant variations in their weight, length, condition factor and specific growth rates that correlated positively (p<0.01) with water temperature and feed conversion efficiency (FCE). Rearing of treated fish in metals deprived environment caused variable retention of selected metals in their body organs as kidney > liver > skin > muscle > fins ≥ gills ≥ bones. C. idella retained significantly higher metals in its body, followed by C. catla and H. molitrix with non-significant differences. Pb retention was significantly higher in fish body, followed by Zn and Ni. The liver of treated fish showed significantly higher depuration of metals (94.06%) while it was lowest (66.06%) in bones. C. catla exhibited significantly higher metal's depuration tendency (96.44%), followed by L. rohita (93.11%), C. idella (93.02%), C. mrigala (89.35%) and H. molitrix (82.60%) with significant differences at p < 0.05. The tendency of fish to depurate Pb from its body was significantly higher (177.94%), followed by Zn (131.13%) and Ni (38.26%).
