  • Ecologische impact (toelichting) Some populations can produce toxins that can cause serious illness in humans but also other animals that feed on these algae.
    Economische impact (toelichting) This populations of this species produce Paralytic Shellfish Toxins (PST). In especially shellfish that feed on these algae, these toxins may reach concentrations that are harmfull for humans. Numerous human illnesses and several deaths have resulted from the consumption of such shellfish. The control measures that have to be in plave to minimize this risk are costly for the shellfish industry.
