“…In addition, C. furcoides cell counts were high compared with Brazilian records of counts that were typically below 30 ind•mL -1 (Santos-Wisniewski et al, 2007;Silva et al, 2012;Cavalcante et al, 2013).…”

“…Given the large size of the dinoflagellate, this translated to a high density of algal biomass. The lower rate of removal during conventional treatment is related to cell density, surficial charge, morphology and motility of the dinoflagellate, which decrease the effectiveness of the sedimentation process during water treatment (Cavalcante et al, 2013;Gil et al, 2012;Henderson et al, 2008).…”

“…is recent in Brazilian water supply reservoirs (Santos-Wisniewski et al, 2007;MatsumuraTundisi et al, 2010;Silva et al, 2012;Cavalcante et al, 2013). Although there are no records about the production of toxins, there are some registers about taste and odour compounds (Hart and Wragg, 2009) and the occurrence has been linked to a decrease in water quality and some problems in water treatment, such as coagulation, sedimentation and reduced life of the filters (Ewerts et al, 2013;Van der Walt, 2011;Hart and Wagg, 2009).…”

“…The filters were stored in amber flasks with 50 mL of 4% Lugol's iodine. The identification of the phytoplankton to genus and species level was based on specialized references and keys elaborated by Bicudo and Menezes (2006), Komárek and Anagnostidis (1998) and Cavalcante et al (2013). Identification and enumeration were conducted with an inverted microscope, ZEISS AXIO VERT A1 (Göttingen, Germany) with a coupled photographic camera, using a 2 mL sedimentation Utermöhl chamber (Flemming, Brazil) and 400X magnification (Edler and Elbrachter, 2010).…”

“…Determinations are made under the Guidelines of the World Health Organization (WHO, 2011), which defines the limit for microcystin-LR as 1 μg•L -1 . In addition to cyanobacterial blooms, blooms of Ceratium Schrank have occurred in tropical fresh waters in Brazil (Santos-Wisniewski et al, 2007;Matsumura-Tundisi et al, 2010;Silva et al, 2012;Cavalcante et al, 2013). Although there is no documented production of toxins by this dinoflagellate, blooms of Ceratium have been related to decreased water quality (Hart and Wagg, 2009;Ewerts et al, 2013) and water treatment efficacy, reducing coagulation, sedimentation and longevity of the filters (Ewerts et al, 2013;Van der Walt, 2011).…”

Algal blooms are a global problem due to various negative effects that can compromise water quality, such as the production of metabolites that are responsible for odour, colour, taste and toxins. In drinking water supplies algae can reduce the aesthetics of potable water when not readily removed by conventional water treatment processes. One of the major challenges in water treatment is the removal of cells without leading to lysis and the consequent release of dissolved metabolites in the water. The Maestra Reservoir, which is located in Caxias do Sul, RS -Brazil, is a small meso-to supereutrophic reservoir. The reservoir provides water for the Celeste Gobatto water treatment plant (Celeste Gobatto WTP) which uses the conventional method of treatment. This study aimed to evaluate the efficacy of conventional water treatment for the removal of algae, cyanobacteria and cyanotoxins. A bloom of Microcystis (Kützing) ex Lemmermann with a density of 23 163 cells•mL -1 , Ceratium furcoides (Levander) Langhans, (5 356 cells•mL -1 ) and a microcystin concentration of 1.97 μg•L -1 was found in the raw water reservoir. Samples sites were assigned the following numbers: (1) raw reservoir water; (2) WTP entry; (3) after sedimentation; (4) filtered water; and (5) treated water. Cell removal was evaluated by cell counting conducted with an inverted microscope, chlorophyll-a by a colorimetric method and microcystin by an enzyme immunoassay kit. Conventional water treatment was effective in removing chlorophyll-a, Microcystis sp. and Ceratium furcoides, mainly in the early treatment steps. Microcystin persisted until the last treatment step, when approximately 50% of the microcystin that had arrived at the WTP was removed by disinfection. Removal of these taxa and toxin was above 98%. Despite the efficacy of Ceratium furcoides removal, the presence of this dinoflagellate in treated water is considered to be large because of its large size.

Invasion of Ceratium furcoides in subtropical lakes in Uruguay: Environmental drivers and fish kill record during its bloom

The invasive freshwater dino agellate Ceratium furcoides is extending its distribution in South America with increasing environmental impacts associated with its blooms. We here report two events related to C. furcoides distribution expansion in Uruguay: 1) the rst appearance and main environmental drivers (physico-chemical variables, extreme wind events and zooplankton composition) of the bloom of C. furcoides in 2012 in a subtropical eutrophic shallow lake (Lake Blanca, Uruguay), and 2) the sh kill event of Prochilodus lineatus likely caused by C. furcoides in 2016 in a deep eutrophic lake (Puente de las Americas, Uruguay), which is the rst sh kill attributable to C. furcoides registered in the world.The bloom of C. furcoides in Lake Blanca started in spring 2012 (October) during a clear water period with high phytoplankton species replacement after a cyanobacterial bloom of Raphidiopsis raciborskii. Extreme wind events during this period resuspended cysts from the sediments, which likely started the C. furcoides bloom. High nutrient availability and low zooplankton grazing, allowed the bloom to expand and reach 96% of the phytoplankton biomass. Our results further indicate that the sh kill of Prochilodus lineatus in Lake Puente de las Americas was likely promoted by the high biomass of C. furcoides bloom, causing gill damage and clogging together with oxygen depletion in the benthic zone. Our study is the earliest record of C. furcoides in Uruguay and it shows the drastic consequences of C. furcoides bloom in freshwaters and its potential of inducing massive sh kills.
