Abstract

Micro-alga such as Chlamydomonas reinhardtii are a key food source for salmon.
Therefore, this study aims to investigate the effects of water contamination on C. reinhardtii
as an indication of how salmon are affected by metal pollutants. C. reinhardtii cells were
grown in three concentrations (0μM, 10μM, 150μM) of copper sulfate. The cells were
counted over 5 days and growth rates were determined for each concentration. No significant
difference was found between the growth rates of C. reinhardtii cells at each concentration.
However, it was observed that an increase in copper sulfate concentration caused a decrease
in the average growth rate. The observed results are likely due to uncertainties in
haemocytometer counts and potential errors in sample preparation. Therefore, further
repetitions of this study are needed in order to determine the potential effect of copper sulfate
on Chlamydomonas reinhardtii.
