Dinoflagellate toxins in northern Baltic sea phytoplankton and zooplankton assemblages
The distribution of dinoflagellate toxins (OA, DTXs, PTXs, YTXs) in plankton communities was studied in the northern Baltic Sea during late summers of 2005 and 2006. The phycotoxins were analysed from samples that contained field collected microplankton in the size range of 20–76 μm, zooplankton collected with a net, and individually hand-picked copepods from open-sea and coastal sampling stati...
متن کاملBacterial bioluminescence as a lure for marine zooplankton and fish.
The benefits of bioluminescence for nonsymbiotic marine bacteria have not been elucidated fully. One of the most commonly cited explanations, proposed more than 30 y ago, is that bioluminescence augments the propagation and dispersal of bacteria by attracting fish to consume the luminous material. This hypothesis, based mostly on the prevalence of luminous bacteria in fish guts, has not been te...
متن کاملFish kills linked to a toxic ambush-predator dinoflagellate: distribution and environmental conditions
The toxic ambush-predator dinoflagellate Pfiesteria piscicida gen. et sp. nov. has been implicated as a causative agent of major fish kills in estuarine ecosystems of the southeastern United States. P, piscicida is stimulated by fresh fish secreta, and it was lethal to all 19 species of native and exotic flnfish and shellfish bioassayed in culture; thus far in field and aquaculture kills linked...

متن کاملPfiesteria piscicida Bibliography
The presence of P. piscicida in Chesapeake Bay is documented. The appearance and behavior of the algae and symptoms associated with fish mortality were consistent with those previously observed in P. piscicida-associated aquaria fish kills in North Carolina. The discovery of P. piscicida in Chesapeake Bay shows that dinoflagellates have a dramatic and far-reaching impact on fish stocks in shall...
