Control of Eutrophication and Toxic Blooms

The options themselves invoke different controls and philosophies. The main techniques may be categorized according to whether they deal with the nutrients directly, or whether they interfere with the physical growth environment, or whether they invoke some form of biological remediation.

Intuition dictates that reducing nutrient inputs, particularly phosphorus, must reduce the supportable biomass. Relationships show that sustained response cannot be effected before it can be demonstrated (i) that nutrient is exhausted at a lower concentration of algae than the existing maxima and (ii) that in situ recycling is unable to make up the shortfall.
