Table 1. The three main databases concerning harmful microalgal species and their impacts. Toxic species cover all those known to include strains that produce toxins and are hence only potentially toxic. Asterisks indicate mandatory data and information (from [2]). formation made available by data

on human health or activities, or on the environment (Table 1). Both databases rely on the volunteer contribution and inputs by regional editor groups and national representatives within ICES and IOC regional groups. Following our calls at the HAB conference in Brasil [3] and in HAN [1] as well as f

Future perspectives The GHSR was initially planned to be the first of a series of periodic global overviews along the line of IPCC climate reports. However, the results obtained so far demonstrate that, while impacts from HABs are expected to increase driven by the growth of the human population and

Fish filler Heterosigma akashiwo in Comau Fjord, Southern Chile In early spring of 1988, a massive bloom of the alga Heterosigma akashiwo was observed in Comau Fjord (422210S), Los Lagos, southern Chile, resulting in severe impacts to the local salmon in- dustry [1]. Over three decades later, on Ma

L-1) of F. japonica in Callao (12S), Pisco (13.70S) This species thrives on eutrophic environments and is frequently observed in coastal and brackish waters [11]. These conditions agree with those observed in Miraflores and Paracas bays on the

Unexpected Prorocentrum bloom and associated gelatinous zooplankton in Alexandria, Egypt We investigated an unprecedented, massive bloom of the dinoflagellate species Prorocentrum minimum and P. triestinum which co-occurred with dense swarms of the salp Thalia democratica. To our knowledge this bloo

Elucidating the origin of tetrodotoxin in New Zealand bivalves Tetrodotoxin (TTX) is a potent neurotoxin that acts by selectively targeting sodium channels, blocking propagation of action potentials and causing paralysis [1]. It has been responsible for countless human intoxications and deaths aroun

Lastly, the possibility that wild P. australis could sequester and accumulate TTX from a dietary source was assessed. A novel method to artificially
