Este es el primer registro del dinoflagelado Lingulodinium polyedrum en un florecimiento de marea roja en la costa del Pacífico Norte de Costa Rica. La muestra fue recolectada en abril de 2000 en Bahía Culebra, Golfo de Papagayo, de un parche de aproximadamente 2000 m2, lo que produjo una coloración roja del agua y un olor fuerte peculiar. Esta especie produce hipnoquistes esféricos que pueden permanecer durante décadas cuando se presentan condiciones de oscuridad o de anoxia; L. polyedrum se había asociado con la producción de toxinas paralizantes como las saxitoxinas y las yesotoxinas. Se observó un segundo parche más pequeño cerca de la playa de Panamá, en la bahía, donde encontramos siete peces globo (Diodontidae) y dos langostas muertas en la arena. Es importante desarrollar un programa de monitoreo para identificar el comportamiento estacional de esta especie y mejorar su impacto en las comunidades humanas costeras.
This is the first record of the dinoflagellate Lingulodinium polyedrum in a red tide bloom in the North Pacific coast of Costa Rica. The sample was collected on April 2000 at Culebra Bay, Gulf of Papagayo, from a patch of aproximatly 2000 m2, which produced a red discoloration of the water and a peculiar strong odor. This species produces spherical hypnocysts that may remain for decades when dark or anoxic conditions are present; L. polyedrumhad been associated with the production of paralyzing toxins such as saxitoxins and yessotoxins. A second smaller patch was observed close Panama beach, into the bay, where we found seven puffer fish (Diodontidae) and two lobsters dead in the sand. It is important to develop a monitoring program to identify seasonal behavior of this species and ameliorate its impact on coastal human communities.
