Abstract

The aim of the present study was to identify the Phytoplankton species which producing Domoic acid and okadaic acid toxins in coastal waters of Banar Abbas city, and to determine the concentration of Domoic acid and okadaic acid toxins in water and Shellfish samples. Water sampling was performed in winter 2015 and summer 2016 from coastal areas overlooking the discharge of municipal and industrial effluents. Shellfish were collected from the coasts of Bandar Abbas and Bandar-e-Lengeh. Phytoplankton toxins were measured by kit method and instrumental analysis based on ELIZA method. Pseudonitzschia delicatissima, Pseudo-nitzschia pungens and Pseudo-nitzschia seriata were identified in the production of Domoic acid, while Dinophysis caudate and Prorocentrum Lima were recorded as okadaic acid producers in the coastal waters of Bandar Abbas. Water-soluble okadaic acid showed significantly higher concentrations than Domoic acid. Instudied Shellfish samples (Circenita callipyga, Barbatia candida, Telescopium telescopiumandThalessa savignyi), the measured concentrations of okadaic acid ranged from 59. 8 ± 2. 38 to 121. 96 ± 28. 25 μ g / kg. This value for Domoic acid was from 0. 85 to 83. 59 ± 38. 72 μ g / kg. Compared to the guideline values, the observed concentrations of okadaic acid and Domoic acid toxins in the studied Shellfish were lower than the allowable level. But this value was recorded for the water-soluble Domoic acid above the allowable value, which requires continuous monitoring to achieve the quantitative and qualitative pattern of Phytoplankton toxins in order to support the safety of the marine ecosystem users in Hormozgan Province.
