Alexandrium abundance, phytoplankton community composition, and abundance data from Prince William Sound (2018-2020) and Lower Cook Inlet and Kachemak Bay (2019-2021), Alaska
Fundamental information is lacking about the distribution and seasonality of Alexandrium catenella, the dinoflagellate causing paralytic shellfish poisoning (PSP) in Alaska. Although effects of PSP toxins (PSTs) on shellfish resources and human health are well recognized, potential impacts of these...

Fundamental information is lacking about the distribution and seasonality of Alexandrium catenella, the dinoflagellate causing paralytic shellfish poisoning (PSP) in Alaska.

This study investigates the interconnectivity of PSTs from Alexandrium to zooplankton, shellfish, forage fish and commercially important predatory fishes in two southcentral Alaska ecosystems: Prince William Sound and Kachemak Bay. The first Objective of this project is to confirm the environmental factors governing seasonality of Alexandrium blooms in relation to shifts in phytoplankton and zooplankton community structure.
