Sažetak
Although harmful algal blooms (red tide, "mucillagine") have been present in the Adriatic Sea for almost thirty years, toxic blooms are a relatively new occurrence in this area. This phenomenon was first recorded in 1989 off the northwest coast of the North Adriatic, the dinoflagellate of ginus Dinophysis being the causative organism of diarrhetic shellfish poisoning (DSP). In this paper we present the first data substantiating the occurrence of Diarrhetic Shellfish Poisoning (DSP) in the central region of the Adriatic Sea (Kaštela bay), registered in the summer of 1995. Toxicity was established using the mouse bio-assay, however the results of the HPLC-directed analysis suggest the observed toxic effects are not associated with the common DSP toxins. The HPLC analysis has shown the presence of an unknown compound structurally related to DTX-2, the concentration of the respective substance being rather high in those samples exhibiting toxicity. In a simultaneously conducted analysis of the phytoplankton population special attention was dedicated to the species from the dinoflagellate group. The origin of mussel toxicity can be traced to Dinophysis sacculus, a suspect toxic species.
