Two different phytoplankton sampling methods (bottle and net sampling) were used to evaluate the concentration of toxic Dinophysis species in seawater and their correlation to mussel toxicity, assessed by mouse bioassay. Dinophysis concentration in net samples revealed the higher correlation to mussel toxicity (r = 0.75, p < 0.01). Net sampling therefore seems more suitable for the detection of low abundance species like Dinophysis characterised by vertical aggregations at different depths in the water column.

Abstract
Two different phytoplankton sampling methods (bottle and net sampling) were used to evaluate the concentration of toxic Dinophysis species in seawater and their correlation to mussel toxicity, assessed by mouse bioassay. Dinophysis concentration in net samples revealed the higher correlation to mussel toxicity (r = 0.75, p < 0.01). Net sampling therefore seems more suitable for the detection of low abundance species like Dinophysis characterised by vertical aggregations at different depths in the water column.File in questo prodotto:
