This report presents the results from the first toxic phytoplankton monitoring program in the Quebec region. Its main objective is to answer basic questions about the distribution of toxic species in the St. Lawrence estuary and northwestern Gulf of St. Lawrence. In 1989, 10 stations were sampled for toxic phytoplankton. Most of these stations were sampled weekly between June and November. The data collected in 1989 show that for most stations only one annual bloom of Alexandrium spp. occurred, predominantly during June and July. At certain stations where the sampling started in early June, the link between the PSP toxicity in shellfish and the toxic blooms was clearly established. The station in the Magdalen Islands warranted special attention, since relatively low but constant numbers of Alexandrium spp. cells were encountered during the summer. The sampling program also demonstrated the wide geographical distribution of potential DSP-producing species, as Dinophysis spp. were found at all stations. Particularly high concentrations were noted in the Baie de Gaspé and Baie des Chaleurs. In view of the 1989 results in the Quebec region, some modifications to the program were proposed for the following years.

Unialgal isolates of the Protogonyaulax (–Gonyaulax) tamarensis/catenella species complex, a group of dinoflagellates which causes paralytic shellfish poisoning (PSP), were subjected to toxin analysis by HPLC. Protogonyaulax isolates from widely separated geographical locations were compared, including the northeastern Pacific (British Columbia and Washington State), eastern Canada, Portugal, the United Kingdom and New Zealand. Two distantly related gonyaulacoid species were also analyzed, but the presence of PSP toxins was not detected. Although Protogonyaulaxisolates varied markedly in total toxin concentration and toxicity, even through the culture cycle, the toxin ratios of individual isolates were distinctive and relatively constant. No toxins were detected in the Plymouth (U.K.) isolate of P. tamarensis, from the species type locality. Two isolates from Vancouver Island (British Columbia), which were previously considered to be non-toxic according to the mouse bioassay, revealed weak toxin spectra by HPLC. Within populations from English Bay (British Columbia) the toxin profiles of tamarensoid isolates tended to be conservative. However, this was not the case for the catenelloid forms from Washington State, which displayed a greater degree of toxin heterogeneity. Significantly, there was no identifiable relationship between toxicity or toxin profiles and the morphological characteristics conventionally used to separate the two dominant morphotypes into species within this species complex.©1987 Pergamon Journals Ltd.
