“…For example a 1950 fish kill in Walvis Bay, South Africa was attributed to Gyrodinium galatheanum (Copenhagen, 1953;Braarud, 1957;Pieterse and Van Der Post, 1967). Laboratory experiments showed this organism causes mortality in juvenile cod and reduced growth in mussels (Nielsen and Strømgen, 1991;Nielsen, 1993). In Alfacs Bay, Spain, Gyrodinium corsicum (Paulmier et al, 1995) was implicated in killing of Sparus aurata Linnaeus (gilthead seabream) in aquaculture ponds (Delgado, 1998).…”

“…Indicates grab-sampl~ng area ratory experiments have shown toxic effects of Chrysochromulina polylepis on eggs and larvae of the ascidian Ciona intestinalis (Granmo et al 1988), blue mussel Mytilus edulis (Granmo et al 1988, Nielsen & Stramgren 1991 and on the nauplii of the crustacean Artemia salina (Edvardsen & Paasche 1992). The toxin seems to be similar to prymnesin, the toxin produced by Prymnesium, In its haemolytic and cytotoxic characteristics resulting from interaction with cell membranes (Shilo 1981, Underdal et al 1989, Yasomoto et al 1990).…”

Do toxic algal blooms affect subtidal soft-bottom communities?

An extensive bloom of the toxic flagellate Chrysochromuha polylepjs occurred over much of the Skagerrak and Kattegat area during May-June 1988 with severe effects on biota in shallow marine habitats. Results reported here are from annual grab-sampling of subtidal soft-bottom communities off the southwest coast of Norway during the period 1986 to 1991 at depths between 69 and 184 m, and describe changes In fauna associated with the toxic algal bloom. In the 3 years prior to the bloom the fauna at each station was persistent and only modest year-to-year changes in the number of species, abundance and species composition were observed. Samples collected 1 yr after the bloom event revealed a significant reduction in both number of species and individuals. The most obvious changes were found at sites situated in accumulation areas characterised by fine sediments indicating a possible connection between the quantity of sinking toxic material and the degree of faunal perturbation. A DCA ordination demonstrated a clear switch in faunal composition in the study area subsequent to the bloom, and a tendency of the fauna to return to the pre-bloom communities 2 yr after the bloom event. Principal species affected were moderately abundant oligochaetes, polychaetes, crustaceans, molluscs and sipunculids. Allocation of each species into the categories 'gaining' and 'losing' according to annual changes in abundance gave a good description of the community disturbance probably induced by the toxic alga. Other possible causes for the observed faunal perturbation may be changes in water temperature, food input, predation interference and changes in sediment composition, but none of these were found to give reliable, alternative explanations for the substantial changes observed in the soft-bottom communities subsequent to the toxic bloom.

“…Different studies have demonstrated that toxic dinoflagellates produce sub-lethal effects in some filter-feeding organisms, affecting byssus production and oxygen consumption, and also reducing feeding activity, which may even be stopped completely due to the closure of the valves Marsden and Shumway 1993). The dinoflagellate Gyrodinium aureolum produces a reduction in the clearance and growth rates, as well as intestinal damage, when it is ingested by the bivalve Mytilus edulis (Nielsen and Strömgren 1991).…”

-Juveniles of the mussel Mytilus chilensis were exposed to a diet containing paralytic shellfish poisoning (PSP) toxins produced by the dinoflagellate Alexandrium catenella (strain ACC02). The feeding behaviour and the dynamics of intoxication and detoxification were evaluated over an intoxication period of nine days, followed by a detoxification period of eight days. A significant reduction in the feeding activity was measured during the first days of exposure to the PSP toxins (days 0 and 2), followed by a period of recovery observed on days 5 and 9, when the clearance rate of the contaminated mussels significantly increased. During the detoxification period, the contaminated bivalves showed a total recovery of clearance rate, and no significant differences were observed between contaminated and control groups. The intoxication dynamic was characterised by a rapid and sustained increase in the amount of PSP toxins accumulated in the tissues of the bivalves. Due to this increase, the level of PSP toxins critical for human consumption was reached on the first day, and at the end of the intoxication period, the mussels had accumulated 1601 μg STX eq. 100 g −1 tissue. During the detoxification period, a decrease of PSP toxins was observed, down to 319 μg STX eq. 100 g −1 tissue. The lower clearance rates observed over the first days of exposure would produce a decrease in the energy intake and could affect the rate of growth of juveniles. Despite this initial effect, the rapid intoxication capacity of M. chilensis corroborates that this species is a good indicator for the early detection of harmful algal blooms.
