| Toxin composition of three species of marine gastropods Zidona angulata, Adelomedon brasiliana and Pachycymbiola brasiliana and the mussel Mytilus edulis, and an Alexandrium tamarense isolate (AMI)from the Mar del Plata coast, were determined by means of a sensitive and specific HPLC technique. Cultures of A. tamarense contain N-sulfocarbamoyl derivatives as major toxins. The next most abundant components were GTX1 neoSTX and GTX4. As minor components, unusual decarbamoyl toxins were detected. Saxitoxin was the lowest of the 10 detectable toxins. Comparison of toxins profiles revealed significant differences between the toxic composition of the dinoflagellate and that accumulated in the tissues of their primary and secondary consumers. In the mussel M.... |

| Spring blooms of the toxic dinoflagellate Alexandrium tamarense in the Argentine sea produce shellfish toxicity through the parallytic shellfish poison (PSP)accumulation. The trace PSP content in the mackerel Scomber japonicus liver was previously demonstrated in the Buenos Aires province coastal region (Carreto et al, 1993a),and a certain capability to accumulate the toxins was suggested.However, it was up to spring 1993 when a great number of PSP intoxicated mackerels where detected for the first time in a wideshelf area off the Buenos Aires province. This area, known as 'El Rincón' (39°00'-40°30'S), has become a growing importance mackerel fishing ground during the last few years. A high PSP concentration was determined in those mackerels, being the... |
