Abstract :
    One of the biggest natural pollutants in marine ecosystems is harmful algal bloom, or red algae, which is created by phytoplankton species, including dinoflagellates. Marine dinoflagellates, with the potential of biotoxin production, have caused increasing concerns in various health, economic and fishing sectors.The important reason for this growth can be found in two areas: the introduction of human pollutants such as: agricultural fertilizers, sewage, non-standard aquaculture activities and inappropriate burial of domestic and industrial wastes in coastal areas and their leachate entering the ecosystem. Sea theme, as well as climate changes, searched. Harmful dinoflagellates cause damage to the health of the marine ecosystem in two ways, either through multiplication and high cellular density, which can cause low oxygen conditions for aquatic life, or With the secretion of natural microalgae toxins, both of which cause the death of organisms. will follow.In addition, algal bloom phenomenon is one of the bad consequences of climate change. The increase of greenhouse gases, global warming and climate change, with changes in atmospheric and weather conditions, fluctuation in the precipitation pattern, increase in rainfall, decrease in temperature and roughness of the sea, intensify this phenomenon. Although one of the negative consequences of climate change is the algal bloom phenomenon, algae can also play a role in reducing the effects of climate change.Algae can reabsorb carbon dioxide gas resulting from industrial activity and thus reduce the concentration of this main gas in the process of climate change. The use of algae to provide food for humans and livestock also reduces the adverse effects of the environment caused by other ways of providing food and contributes to the stability of climatic conditions. The current study examines the environmental and fisheries consequences of algal blooms and aquatic ecosystems, citing related scientific articles and journals.
