OPEN-ENDED QUESTION ABOUT HARMFUL ALGAE

Light inverted microscope identification problems

Update with new species or change in taxonomy

Other methods of identification

Sampling managment (methods, frequency)

Why algae produce toxins and how many

Behaviour of shellfish with harmful algae (presence of algae doesn’t link always to marine biotoxin in shellfish)

Only cultivation of harmful algae can improve the knowledge of biotoxin in shellfish

Harmful algae are a recent discovery (’90s)
