Yesudass Thangam ^[2] | Mathan Ramesh

Abstract: This study represents the data on changes of nitrite in the hematocrit value of fish Cirrhinus mrigala exposed to sublethal concentration of nitrite was presented in the Table 13 and Fig.12. At the end of 7th day, hematocrit value was increased (+4.58 %) when compared to that of the control group. In the rest of the study period (14 to 35th days), hematocrit value was declined in nitrite exposed fish showing a percent decrease of 8.79, 8.33, 12.53 and 13.01 at the end of 14th, 21st, 28th and 35th days, respectively. Table 14 and Fig.13 furnish the data on changes in the MCV value of fish Cirrhinus mrigala exposed to sublethal concentration of nitrite for 35 days. During the above treatment period, MCV value was found to slightly increased at the end of 7th day showing a percent increase of 2.653. However after 7th day, MCV value was found to be decreased showing a percent decrease of -3.71, -9.35, and -7.28 at the end of 14th, 21st and 28th days. In contrast to the above decrease, a marginal percent increase of 0.38 was noted at the end of 35th day.
