"Overall, our results suggest that climate change—ocean warming—may promote the blooms of toxic harmful algae, leading to significant negative ecological effects," said Vidyarathna. Multi-species algicidal bacteria were enriched by utilizing immobilized carriers in a pilot scale experiment, which significantly promoted the effect of algal control in the reactors. Blue-green algae or cyanobacteria, are a natural part of a healthy water ecosystem. Harmful algal blooms are the rapid growth of algae or cyanobacteria that can cause harm to people, animals, or the local ecology. A harmful algal or cyanobacterial bloom can look like foam, scum, paint, or mats on the surface of water and can be different colors. Cyanobacteria (sometimes called blue-green algae) occur naturally in fresh- water.

To measure the change in toxicity with regards to rising water temperatures, the researchers first exposed the algae to a range of temperatures, from about 64 to 89 degrees Fahrenheit, extracted everything out of the harmful algal cells, and exposed them to mammalian red blood cells or the fish gill cells in cultures. It is not certain what the full effect of the use of irrigation water contaminated with blue-green algae is on plants, although scientific research suggests that the use of contaminated irrigation water … Algae cells need light, water, carbon dioxide and nutrients, which are naturally occurring in water, … Dogs may ingest algae if they lick their coats after leaving the water. Scrub the pitcher well and rinse thoroughly before refilling the water reservoir with water. The rapid and large growth of blue-green algae (cyanobacteria) is known as a "Harmful Algal Bloom"(HAB). Under certain conditions, they can multiply quickly, creating a highly concentrated area known as a cyanobacterial harmful algal bloom, or cyanoHAB. Harmful cyanobacterial “algal” blooms and associated toxins are of concern in many parts of the world because of their effects on drinking water, water-based recreation, and watershed ecology. As the algae die and decompose, high levels of organic matter and the decomposing organisms deplete the water of available oxygen, causing the death of other organisms, such as fish. Pets, especially dogs, are susceptible to harmful algae because they are relatively small and tend to swallow more water while swimming and playing (e.g., retrieving a ball from the water). Therefore, an algae problem is often unwanted, and algae control is desired. A bloom of harmful algae can completely and permanently alter the structure of a food chain, causing massive die-offs of shellfish, marine mammals, fish, seabirds, and other animals that consume them.

The human illnesses caused by HABs, though rare, can be debilitating or even fatal. Domestic water supplies in the cities Brandon and Morden depend on the Assiniboine River and Lake Minnewasta. Harmful Algal Blooms Increase as Lake Water Warms Increasing temperatures as a result of climate change have aided blooms of algae By Erica Rex , ClimateWire on January 8, 2013 Anoxia – Anoxic Event: Anoxia is a lack of oxygen caused by excessive nutrients in waterways which triggers algae growth. Algal blooms occur when there are overgrowths of algae, including green, brown, or red microalgae, or cyanobacteria that are commonly referred to as blue-green algae. Macrophytic algae can occasionally grow to nuisance levels but does not pose any health risks to humans or animals. Avoid skin contact with the water.

Blue-Green Algae and Cyanobacteria Treatment & Management in Ponds. Deterioration of water quality and limits access to safe drinking water; Algal blooms are highly toxic and once the water reaches the anaerobic conditions, the growth of more toxic bacterial is promoted. Most algae can be controlled using EPA registered algaecides. Harmful algal blooms, or HABs, occur when algae—simple photosynthetic organisms that live in salt water and freshwater—grow out of control while producing toxic or harmful effects on people, fish, shellfish, marine mammals, other aquatic life, or birds.
