Abstract

Harmful algae reproduction (HAB) occurs when algae producing toxins grow in water algae are microscopic organisms that live in an aquatic environment and through photosynthesis generate chemical energy from sunlight like higher plants. The growth of algae or algal blooms is visible with naked eye and are green layers, it might be blue, red or brown depending on the type of algae natural waters such as lakes, ponds and rivers always contain algae, but few species produce toxins In such algae, the production of toxins can be induced by environmental conditions like light, temperature and nutrients levels. The release of algae or algae toxins can have serious adverse effects on humans, fish, animals and other strata of the ecosystem.
