Another technique now in development involves the use of underwater sensors on buoys or attached to unmanned underwater vehicles. Some harmful algal bloom bacteria are, in a sense, predators of the resident fish population. Marine and fresh waters teem with life, much of it microscopic and most of it beneficial and harmless. A harmful algal bloom (HAB) is an algal bloom that causes negative impacts to other organisms via production of natural toxins, mechanical damage to other organisms, or by other means. Harmful algal bloom discovered on Lake George. Harmful algal blooms cause massive problems in coastal areas and lakes across the United States. They can look like foam, scum, or mats on the surface of water and can be different colors. Blooms can block light to organisms lower in the water column, or even clog or harm fish gills. It is important to highlight the fact that some instances of algal bloom are harmless. Introduction. In other cases, HABs may be linked to “overfeeding.” This occurs when nutrients (mainly phosphorus and nitrogen) from sources such as lawns and agriculture flow into bays, rivers, and the sea, and build up at a rate that “overfeeds” the algae that exist normally in the environment. The human illnesses caused by HABs, though rare, can be debilitating or even fatal. Harmful algal blooms or HABs are algal blooms composed of phytoplankton that naturally produce biotoxins. Collectively, these events are called harmful algal blooms, or HABs.
