The species naturally produces the toxin, but as the lagoon gains excess nutrients via runoff from land, the algae have the potential to bloom more often and severely, leading to more saxitoxins being introduced into the food web. Cysts are spherical, of chorate type, with ∼152 oblate tubular processes of variable length and randomly arranged (Figures 1D,E). Antecedentes de Presencia de Marea Roja en Costas Nacionales.

This mini-review ends with a viewpoint of management and research strategies to better understand the factors that play essential roles in the bloom dynamics and toxicity of this species. For research purposes, shellfish toxicity is determined by standard mouse bioassay (AOAC, 1995), and high-performance liquid chromatography (HPLC-FD with pre-column oxidation) (AOAC, 2005; Lawrence et al., 2005). For sample preservation, both Lugol and neutralized formalin are used (Throndsen, 1978), and in few cases, the combination of these fixatives is considered to preserve samples for long periods. For food safety, health authorities use the standard AOAC mouse bioassay (AOAC, 1995) and fast track probes (Scotia Rapid Tests) to estimate PSP toxins concentration in shellfish monthly.

The data obtained so far on P. bahamense spatial and population variability in Mexican Pacific and the Gulf of Mexico, suggest a seasonal and latitudinal pattern. We have examined the sterol compositions of two isolates of P. bahamense from Indian River Lagoon and Tampa Bay, Florida, and have found both to produce three sterols: cholesterol, dinosterol, and 4α‐methylgorgostanol.

Environmental forcing on the flux of organic-walled dinoflagellate cysts in recent sediments from a subtropical lagoon in the Gulf of California. Pyrodinium bahamense has caused more human illnesses and fatalities than any other PST producing dinoflagellate in Mexico (Table 1). At that time, it was believed that the species had a distribution restricted to the Bahamas; however, at present, the vegetative stage (Figures 1B,C) is distributed in almost all coastal margin of Gulf of Mexico, Caribbean Sea, Gulf of California, and Mexican Pacific (Figure 1A). was until recently thought to be non-toxic (Steidinger and Tangen 1997).

Pyrodinium bahamense, along with many other dinoflagellates, are known for secreting toxins that cause Paralytic Shellfish Poisoning (PSP). The theca has a granular surface and numerous trichocyst pores, there is a pore in the 4′ apical plate, and the apical pore complex consists of a comma-shaped granular closing plate and 9–14 pores. From tropical to subtropical regions, the abundance, seasonality, and species distribution, tends to decrease. Mar. Res. (2014). Maclean, J. L. (1989). Harmful Algae News 45, 2–3. (2013). Blooms of P. bahamense are generally aperiodic and unpredictable (Usup et al., 2012); nevertheless, on a large temporal scale, there is some evidence that significant blooms overlap with peaks of El Niño and La Niña cycles (Maclean, 1989; Usup and Azanza, 1998; Phlips et al., 2006).

Despite species seasonality that vary with local physiography, hydrography, and climate (Usup et al., 2012), blooms are more predictable at a smaller and local scale (Azanza and Taylor, 2001).

In contrast, in the southern Gulf of California, moderate (63–151 × 103 cells L-1), and short-term blooms are influenced by a short summer rainy season (August–September), relatively high seawater temperature (25–32°C), typical salinity (31–36 ups), intense sunlight, and relatively high concentrations of ammonium (0.37–33.04 μM) and phosphates (0.68–2.87 μM); the last one, in turn, depending on rainfall and runoff and seems stronger on the eastern side of the gulf (Morquecho et al., 2012). Palynol. High‐biomass blooms of the toxic dinoflagellate Pyrodinium bahamense occur most summers in Tampa Bay, Florida, USA, posing a recurring threat to ecosystem health.
