Our hypothesis was determined to be validated. The results displayed the high number of lysed eggs seen in both condition groups, while there were no lysed eggs seen in the control samples. This can be due to the detrimental pollutant negatively impacting their gametes. Like the study previously mentioned, although there is no physical abnormalities displayed in the egg or sperm cells, there are clear repercussions shown once fertilization has initiated. It has been studied that pollutants significantly decrease the success rate of fertilization, as well as increased abnormal larval development (Vashchenko 1980). There should not really be lysed eggs occurring in pure seawater, as that is the most optimal of conditions for eggs and larvae to develop into adults.
