Blue-Green Algae Alert

Blue green algae, also known as cyanobacteria is a type of bacteria which uses the sun’s energy to make food in the same way that plants do. They are commonly found in estuaries, inland waters and sea.

Blue-green algae grows in water which is enriched with nitrates and phosphates. Warm weather conditions along with nutrients result in algal blooms which produce a musty odour.

Though, they play an important role in shaping the biosphere, when the blooms die they break down, using up oxygen in the water and this causes problems for aquatic life such as fish.

Although many blue-green algae blooms are not toxic, some produce toxins which can irritate the skin and if swallowed, cause diarrhea and vomiting. High concentration level of toxins cause liver and nervous system damage. The following measures can help prevent a blue-green algae bloom from occurring:

• Avoid overfeeding fish or birds; this reduces the cause for nutrient buildup.
• Plant native flora around ponds which help in filtering water.
• Avoid overuse of fertilizers, especially near bodies of water.

Although it is not advisable to stop blue green algae blooms, we need to follow proper guidelines to control their growth.
