“Less dense water comes to the surface because of the warming of oceans, encouraging these intense blooms, which has an adverse impact on fisheries. Currently, the western coast, Persian Gulf, and Oman are largely affected, but if it keeps on increasing, it will have drastic effects on fisheries along the Indian coast. That could be alarming,” S.C. Shenoi, director of INCOIS, told the newspaper Mint.
Other scientists have linked the appearance of the neon-blue waves to the dumping of fertilizers and waste along India’s western coast, which caused the death of fish and other wildlife.
“Unfortunately, these beautiful patches indicate zones of decline because fish cannot thrive and sometimes die because of these blooms,” the study said. The organism is harmful to fish because it competes with them for food and chokes their supply. It also excretes large amounts of ammonia, which can be deadly for fish.
