The first incidence of algal blooms within Ghana’s west coast was recorded in 1993; however, many years down the line, growth was still persistent in her territorial waters. A lasting solution is yet to be found. This has therefore led to several social, economic and environmental problems in the affected regions. The study outlined the possible causes and effects of algal blooms within Ghana’s West Coast. The perception of the local people with regard to the causes was also investigated. The method used was direct observation as well as questionnaires following a case study approach in the Half Asini District. This was to address the pertinent question of what the people think is the cause of the bloom. The study found that the growth of algae was alarming, with a newer breed having a much negative consequence on the economic livelihood of the people and environment. It was also found that current studies on the issue were minimal—with less than necessary attention being given by stakeholders. However, scientific investigations are underway, although a preliminary report suggested that it is a migration of Sargasso Sea species. Recommendations included the need for consented government efforts to investigate, device a control measure to curtail its spread, and continuous public education as a control measure.
