Sensitivity of dinoflagellates to mechanical stressors as a potential target to control harmful blooms in aquaculture |
Olga Matantseva, Mariia Berdieva and Ilya Pozdnyakov Institute of Cytology RAS, 194064 St. Petersburg, Russia | Submitted March 13, 2021 | Accepted April 17, 2021 | Summary Dinoflagellates are diverse and widely spread single-celled eukaryotes causing harmful algal blooms (HABs) in the marine environment. Many dinoflagellate species produce potent toxins that can be accumulated in the tissues of marine organisms, thus posing a threat to the organisms at higher trophic levels, including humans. Harmful dinoflagellate blooms in aquaculture represent a serious problem requiring sustainable solutions. In the first part of this article, we provide a concise review of the existing techniques used to mitigate dinoflagellate blooms. In the second part, we discuss the reasons and consequences of the sensitivity of dinoflagellates to mechanical stressors, as well as a potential approach to control HABs in aquaculture based on this physiological hallmark. We argue that the sensitivity of dinoflagellates to mechanical stressors is a prospective target for effective HAB mitigation with low ecosystem risk.
Key words: aquaculture, dinoflagellates, ecdysis, harmful algal blooms
