Cyanobacteria blooms in freshwater lakes or rivers may appear bright green, often with surface streaks which looks like floating paint.Cyanobacterial blooms are a global problem. 2008). The coral polyp creates a shell around itself, and algae grow inside that shell in perfect harmony. Harmful effects of Algae Under certain conditions algae produce 'blooms', that is dense masses of material. For example, a densely concentrated algal bloom can deplete oxygen in the water due to the high respiration rate of the algae, or by bacterial respiration during their decay. harmful effects of algae. For most people, it is impossible to go even a day without coming into contact with electronic devices such as laptops, tablets and cell phones. The variation patterns of cell numbers and growth rates with light intensity during growth process were different among species. They provide food for fish, whales and many other sea animals. This algal bloom mainly destroys aquatic organisms in the ocean. These fish effectively suffocated, then, due to the depleted oxygen in the water.
