Blue green algae occurred at densities from 1.0 x 10-2 to 8.0 x 10-6 CFU/cm-2 and their abundance was correlated to pH and available `P’ content of soil. 'Bloom' is the term used to describe an accumulation of algal cells to a point where they discolour the water, form scums, produce unpleasant tastes and odours, affect fish populations and reduce the water quality. The use of algae in integrated aquaculture has also been recently reviewed by Turan (2009). Cyanobacteria (blue-green algae) In lakes and reservoirs, symptoms of eutrophic situations are the late summer cyanobacteria surface blooms that occur when the water is thermally stratified, sunlight intensity is high, there is a period of mild weather (low turbulence and calm winds) and the N:P ratio is low. There are many types of freshwater algae; the most common groups are diatoms, green algae and cyanobacteria (also known as blue‐green algae). (See arrow on Photo 2.) Too much algal growth can have dire consequences for the water’s inhabitants - killing large numbers of fish, either by the toxic effects of the algae itself or de-oxygenation of the water. The AFA is then chilled and sold frozen or dried at low temperatures and sold as a powder.
