Abstract
Harmful Algal Blooms (HABs) have become an
increasing threat to marine ecosystems, fisheries, and public health along
India’s vast coastline. These blooms, caused by the rapid proliferation of
toxic or high-biomass phytoplankton, lead to oxygen depletion, fish kills,
seafood contamination, and economic losses in coastal communities. This
paper examines the primary causes of HABs in Indian waters,
including nutrient pollution (eutrophication), climate change, and coastal
upwelling. It also discusses their ecological and socioeconomic
consequences, such as biodiversity loss, fishery collapses, and human
health risks from toxins like paralytic shellfish poisoning (PSP) and
ciguatera. Furthermore, the study evaluates current monitoring systems,
early warning mechanisms, and mitigation strategies, including nutrient
management, bioremediation, and AI-driven forecasting models. By analyzing case
studies from Kerala, Tamil Nadu, and the Arabian Sea, this research
highlights policy gaps and recommends adaptive measures to combat
HABs under changing climatic conditions.
