A study on the effects of volcanic ash on the growth and mortality of Tilapia nilotica fingerling and junevile
Tilapia nilotica fingerlings and juveniles were exposed to high (2-3 g/L), median (1.2-4, g/L) and low (0.4-0.6 g/L) concentrations of volcanic ash for a period of 90 days of three months. Such exposure did not cause mortality but instead, helped in the promotion of algae (an alternative feed), lead...

| Summary: | Tilapia nilotica fingerlings and juveniles were exposed to high (2-3 g/L), median (1.2-4, g/L) and low (0.4-0.6 g/L) concentrations of volcanic ash for a period of 90 days of three months. Such exposure did not cause mortality but instead, helped in the promotion of algae (an alternative feed), leading to differences in feeding habits between the control and the treatment group (the control consumed less feeds). After the experiment, the tissues of the different organs (gills, liver and intestine) of the control as well as the treatment group were observed. It was reported that there is no detectable abnormalities between the sample of the control and the treatment group. |
