A decade of fish-killing Prymnesium parvum blooms in Texas: roles of inflow and salinity

Fish-killing Prymnesium parvum blooms have occurred in south-central USA for at least ∼30 years, with the last decade experiencing recurrent blooms of large magnitude. In the systems reported here, Lakes Possum Kingdom, Granbury and Whitney (Texas), P. parvum blooms were winter phenomena developing...

Zusammenfassung:Fish-killing Prymnesium parvum blooms have occurred in south-central USA for at least ∼30 years, with the last decade experiencing recurrent blooms of large magnitude. In the systems reported here, Lakes Possum Kingdom, Granbury and Whitney (Texas), P. parvum blooms were winter phenomena developing under conditions far from the growth optimum. Bloom thresholds of 10 × 106 cells L−1 were observed as a function of inflow and salinity for the period 2000-2009. In Lake Possum Kingdom, blooms occurred only when 7-day accumulated inflows were 1.5 psu. For Lakes Granbury and Whitney, blooms occurred when 7-day accumulated inflows were
