Comparative Study of the Effects of Gamalin 20 on Two Different Fishes

Abstract

This paper compares the mortality rate of two different fish species (Clarias lazera and Cyprinus catpio) exposed to equal concentrations of gamalin 20. The effect of fish poisons on man and the danger of killing fishes with toxicants are also discussed. Observations on the experiment lasted for 39 minutes on the mortality (M), swimming movement (SM), opercular movement (OM), and movement of the fins (FM). The mortality rate was graphically represented with a combined bar graph using shaded and black bars representing Clarias Lazera and Cyprinus carped respectively. It was observed that there was a 100% mortality rate by the toxicant (gamalin 20) for Carlo Laura but that the scaly nature of Cyprinus Carpio must have contributed to the resistant attribute. The researchers, therefore, recommend that there is a need to stop the use of toxicants of any nature during fishing to minimize depletion of fish in particular and aquatic fauna in general.
