Abstract
15genus 30 species of dinoflagellate cysts are identified from KMZK5 Core samples of(recent) marine sediment in Luoyuan Bay mouth,Fujian.All of these dinoflagellate cysts are the first record in Luyuan Bay,12 species of them are not found in near sea area such as Sansha Bay and Minjiang Estuary,among them Alexandrium affine,A.minutum,A.tamarense,Gonyaulax spinifera,Gymnodinium catenatum and Scrippsiella trochoidea are toxic.The density and vertical distribution characterestics of important and toxic dinoflgellate cysts are also studied.
A significance statement is not available in the OpenAlex record.

Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
