Heterosigma akashiwo, a Fish-Killing Flagellate

Heterosigma akashiwo is a golden-brown unicellular phytoflagellate with high potential to create harmful algal blooms (HABs) and kill fish in many coastal regions worldwide, resulting significant economic losses. Climate change global warming have been introduced as triggers that impact the frequency severity of H. other bloom-forming species past decades. In this review paper, author tried briefly discuss morphology taxonomy show how environmental parameters can influence physiology toxicity species. Although toxin production mechanisms are still conundrum, proposed fish-killing will be reviewed next step.
