[marineman]

This is a very broad question, do you mean the harmful effects of harmful algae blooms, specific algae species e.g. pseudo-nitzschia produces a secondary metabolite called domoic acid which is a neurotoxin and bio accumulates in marine life causing respiratory problems and can lead to amnesiac shellfish poisoning. Also do you mean in refernce to macro algae? Are you interested in the economic effects ? etc..
