A Research Study On Blue Green Algae Blooms Essay

There are between 1000 and 2000 species of cyanobacteria (blue-green algae) worldwide that can colonize to form a Harmful Algal Bloom (HAB) (Krogmann 1981). Degraded water quality from increased nutrient pollution promotes the development and persistence of many HABs and is one of the reasons for their expansion and proliferation in aquatic environments. HABs are unfortunately a growing problem in Canada over the last few years. Several cases of blue-green algae blooms have been reported in Manitoba’s Lake Winnipeg over the past few years. Algal blooms in Lake Winnipeg have increased in intensity and frequency with accumulation of phosphorus and nitrogen nutrients in the lake (Manitoba Water Stewardship 2011). Multiple public health advisories have been issued in Quebec due to Microcystin concentrations exceeding the Canadian drinking water guidelines in Missisquoi Bay. The blooms had been appearing since 2000, so a quantitative approach was developed for the detection of cyanobacteria blooms (Fortin et al. 2010). The first documented HAB in Newfoundland and Labrador was blue-green algae in the late summer and early fall of 2007 and in the spring of 2008 (Government of Newfoundland and Labrador 2008). In 2011, Lake Erie, Ontario, experienced a severe harmful algal bloom consisting of the following toxic cyanobacteria genera: Microcystis and Anabaena (Michalak et al. 2013). Nova Scotia has documented incidents of algae blooms in lakes including Porcupine Lake (Digby), Fanning…
