Algal blooms hurt the system in two ways First, they cloud the water and block sunlight, causing underwater grasses to die. Because these grasses provide food and shelter for aquatic creatures, spawning and nursery habitat is destroved and waterfow have less to eat when grasses die off

Second when the algae die and decompose, oXygen is used up. Dissolved oxygen in the water is essential to most organisms living in the water, such as fish and crabs. Increased eutrophication from nutrient enrichment due to human activities is one of the leading problems facing some estuaries in the mid-Atlantic

Origin of the concept of eutrophication in fresh waters The idea of eutrophication began with limnologists. Early in the 20th century. northern European limnologists distinguished oligotrophic from eutrophic lakes. The former were nutrient-poor the latter, nutrient-rich

The uk defines 10 mg chl m-3 as a Environmental quality standard(eqs) for coastal waters. If chlorophyll frequently exceeds this level in summer, a water body should be labelled ' eutrophic. This label is objective and does not necessarily imply that undesirable disturbances will result some coastal seas are naturally eutrophic-for example, those in upwelling regions
