| Abstract: | Toxicity
of naphthalene was carried out on Metapenaeus affinis (H. Milne
Edward, 1837) to investigate its effects on growth , metabolic index
and biochemical constituents. Growth rate in terms of weight gain was 32.13% in
control, 12.12% in 0.125 ppm and only 5.22% in 0.25 ppm. Metabolic index
assessed in terms of oxygen consumption showed a reduction in respiratory rate
up to 44.4% in prawns exposed to naphthalene. Activity increased initially but
reduced subsequently. Protein content and organic carbon of the body tissue of
juveniles showed reduction on exposure to naphthalene. Inhibitory effect was
dose dependent and duration of exposure. However, the lipid content increased
after exposure to naphthalene. Changes in the growth and respiratory rate and
other biochemical constituents resulting from exposure to naphthalene indicate
some adaptive response and recovery during detoxification in the prawns exposed
to pollutant. Study revealed that the physiological and biochemical parameters
could be used as indicator of stress condition in aquatic organisms and the use
of naphthalene should be regulated because of its toxic nature. |
