Abstract/Summary
The effects of stocking density and exposure to arsenic pentoxide(AsV) on the oxygen consumption of Tilapia nilotica fingerlings were investigated using a static assay system. Fingerlings with a mean weight of 1.35 g were stocked at 0.531 gm/cm/1/fish and 1.03 gm/cm.1/fish. Fingerling were exposed to arsenic pentoxide (AsV) concentrations of 5 ppm and 10 ppm during the test. An oxygen probe(YSI) connected to a digital oxygen meter (YSI) was used to measure the dissolved oxygen level in water at the start of the test and every 30 minutes within the 2-hour culture period.Results of the study showed that exposure to increasing concentrations of arsenic pentoxide (AsV) significantly (p0.05) increased the oxygen consumption of the fingerlings. Increase in stocking density however caused a significant (p0.05) reduction in the oxygen consumption of the fingerlings.The interaction of stocking density and arsenic exposure did not have a significant (p.05) effect on the oxygen consumption rate of the test organisms.
