Algal blooms have the potential to wipe out fish farms virtually overnight. Contamination of seafoods with algal toxins can poison human consumers of fish and shellfish. During the past two decades, globally there have been significant increases in economic loss and human health impact due to harmful algal blooms.

Harmful Australian Marine Microalgae offers fish and shellfish farmers information on how to effectively identify and monitor for the presence of algal species and take the appropriate species-specific countermeasures. Species descriptions are accompanied by a summary of the known distribution of the alga, its toxicology and, where available, suggestions for countermeasures. The book includes line drawings, light micrographs and electron micrographs to aid identification, as well as references and resources for further information. This guide will be valuable to fisheries and public health officials as well as all those involved in environmental water quality assessment.


  • The most authoritative and up-to-date guide to Australian harmful marine microalgae, covering over 100 species.
  • Introduces and describes algal species in an accessible and practical way for students, researchers and practitioners.
  • Gives aquaculture managers a critical resource toward early warning of seafood toxins in shellfish and aquaculture fish kills.
