Sažetak
Although monitoring of toxic algae in the middle Adriatic has been conducted for many years, the analysis of shellfish toxicity by mouse bioassay and HPLC was initiated in the fall of 1994. The results of the HPLC analysis indicated the presence of DSP and PSP toxins in the shellfish from the Kaštela bay, although the concentrations were too low for an identification by mouse bioassay. In the summer of 1995 and 1996 DSP toxicity was confirmed by mouse bioassay and HPLC analysis. The presence of DSP toxins in shellfish has been associated with the occurrence of the Dinophysis species (D. sacculus, D. fortii, D. caudata, D. rotundata). PSP toxins, found only in traces, were associated with the occurrence of the Alexandrium minutum bloom. This study was directed to the detailed analysis of the species D. sacculus, an autochtonous species found in the Bay. Its presence in the phytoplankton community was recorded from May to October, simultaneously with the occurrence of shellfish toxicity.
