| ABSTRACT The Baconao Lagoon is a tropical, coastal and littoral ecosystem which receives continuous natural and human perturbations; favoring the eutrophication process, and consequently, the phytoplankton proliferation. The starting point of this research begins with a massive fish kill report into the lagoon on May 2017, being the main objective to document the implementation of a risk management protocol for the phycotoxin presence, adapted to the ecosystem conditions, considering the characterization of the risk event, focusing on mitigation and prevention of negative impacts. The presence of a mix Harmful Algal Bloom (HAB) in remission was confirmed, with negative implications to the entire ecosystem. It was identified the presence of abundant motile... |

| Dinoflagellates of the genus Alexandrium are a major cause of harmful algal blooms (HABs) that have increasingly disrupted coastal ecosystems for the last several decades. Microalgae from the genus Alexandrium are known to produce paralytic shellfish toxins (PST) but also bioactive extracellular compounds (BEC) that can display cytotoxic, allelopathic, ichtyotoxic or haemolytic effects upon marine organisms. The objective of this experimental study was to assess the effects of PST and BEC produced by A. minutum upon juvenile great scallops Pecten maximus. Scallops were exposed for one week to two different strains of A. minutum, the first producing both PST and BEC and the second producing only BEC. Escape response to starfish, daily shell growth,... |
