Benthic algae in Lough Neagh,oes not exceed 3 m (Fig. 12.1). This represents an area of approximately 50 km., which is about 13% of the surface area of the lake. This inshore zone consists mainly of rocks and stones (Briggs, 1984) but there are also long stretches of sandy beaches. Both of these are erosive environments subject

Physiological ecology of Lough Neagh phytoplankton,cept for a short period during the spring diatom bloom. The regularity of this cycle, with . dominant during the spring and early summer, giving way to . for the remainder of the year suggests that the cycle may be controlled by seasonal changes in light or temperature or a combination of the two.

Heterotrophic micro-organisms in the water column and sediments of Lough Neagh,ly (not just in Lough Neagh) but an increasing body of evidence is accumulating (Overbeck, 1974; Berrie, 1976) which suggests that only a small proportion of freshwater primary production may pass directly to grazing zooplankton. Up to 90% has been found to enter the detrital food web as decaying ph
