Outlining the causes and effects of Algae bloom at Ghana’s West Coast

Abstract

The first incidence of algal bloom within Ghana’s west coast was recorded in 1993, however many years down the line, the growth is 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 bloom within Ghana’s West Coast. The perception of the local people with regards to the causes was also investigated. The method used was by direct observation and use of 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 stakeholder. However, scientific investigations were underway, though a preliminary report suggested 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 was recommended as well.

Advantageous and Disadvantageous of Non Classical Biomanipulation

“…Use of planktivorous fish as contrast to piscivorous fish for elimination of blue green algae had been done in closed water body and open lake ecosystem as well. Around sixteen studies [31], found the successful elimination of algae blooms with silver carp and some studies observed no or adverse effect [32][33][34]. Certain studies lead to controversial situation on the use of silver carp for the management of phytoplankton that increase their number instead of ceasing them [35,36].…”
