Differential tolerance to cyanobacterial exposure between geographically distinct populations of Perca fluviatilis

Chemical ecology of marine plankton

“…94 European perch from a marine site and a eutrophic lake site which had been previously exposed to annual cyanobacterial blooms developed a greater tolerance to the toxic cyanobacteria than their counterparts from an oligotrophic lake site and a riverine site that were rarely exposed to cyanobacterial blooms. 94 European perch from the marine and eutrophic sites were observed to increase glutathione-S-transferase (GST) mediated detoxication when exposed to either Nodularia spp., consequently allowing them to excrete cyanobacterial toxins and making them more tolerant to Nodularia exposure. 94 The comparable response of perch to both toxic and non-toxic algal species suggests that 40 is not the toxin responsible for the toxicity of Nodularia spp.…”

“…During the past two years, multiple studies [93][94][95][96][97][98] have assessed various negative impacts of toxins from harmful algal species, including cyanobacteria, diatoms, and dinoagellates, on sh physiology and behavior. When black perch Embiotoca jacksoni were exposed to bloom-like concentrations of two strains of the marine cyanobacterium Synechococcus sp.…”

“…93 Another study highlighted the adaptations of certain populations of European perch, Perca uviatilis, to cyanobacterial blooms. 94 Four different populations of European perch were exposed to the cyanobacterium Nodularia spumigena, a producer of the toxin nodularin (40), and its non-toxic relative Nodularia harveyana. 94 European perch from a marine site and a eutrophic lake site which had been previously exposed to annual cyanobacterial blooms developed a greater tolerance to the toxic cyanobacteria than their counterparts from an oligotrophic lake site and a riverine site that were rarely exposed to cyanobacterial blooms.…”
