J. Aquat. Biol. VL - 2 IS - 3 SE - Articles DO - 10.22034/ijab.v2i3.76 UR - https://ij-aquaticbiology.com/index.php/ijab/article/view/76 SP - 129-137 AB - <p>Copper is most toxic metal in marine organisms. Characterization of protein occurring in the metabolically active tissues of muscle (MU), hepatopancreas (HP) and gills (GL) of the spiny lobster, <em>Panulirus homarus homarus</em> on exposure to two sub-lethal doses (9.55 and 19.1 µg/l) of copper were studied for 28 days of exposure (DoE). The electrophoretic pattern of muscle, hepatopancreas and gill proteins revealed 12, 8 and 8 slow moving bands (control). The number of bands decreased to 8 and 7, 6 and 5, 6 and 4 after 7 days of exposure to 9.55 µg/l and 19.1 µg/l concentrations of copper, respectively. After 28 days, the protein bands decreased to 7 and 6, 5 and 4, 4 and 4 at 9.55 µg/l and 19.1 µg/l concentrations of copper, respectively. Present study to indicate that to avoid the Cupro-Nickel coil in lobster holding centers in chiller plants used for cooling of water was found to be responsible for the mortality of lobsters during live transportation.</p> ER -
