• Two phases of the life cycle were typical for this alga : non-motile mature vegetative and motile generative cells.

• While the interpretation of these ribbon-like megascopic remains as a eukaryotic alga seems plausible and attractive, they may be colonial cyanobacteria.

• The few specimens taken are doubtless from unkilled patches of this alga in tanks.

• The evidence is that blooms of toxic algae are naturally occurring and are triggered primarily by combinations of calm water and good sunlight.

• Nitrogen and phosphorus take oxygen from the seabed and feed poisonous algae at the surface.

• Dimethyl sulfide is believed to arise in surface water from the natural biochemistry of certain species of marine algae.

• They have increasingly acted as a fertiliser for algae, which then use up the oxygen in the water as they grow rapidly.

• Let us consider the algae that form already.

• The clear waters were invaded by a particularly potent algae.

• The simplest process would be to grow green algae and extract them from water, dry them and burn the resulting powder.

• Because of the very mobile nature of marine algae, it is necessary to include a safety margin to ensure protection of public health.

• Imagine if we could understand how algae produce oxygen from sunlight.

• Scientists at the directorate of fisheries research routinely monitor molluscan shellfish, principally mussels, for the toxin which they can accumulate from certain algae.
