Accumulation and Depuration of PSP Toxin (Paralytic Shellfish Poisoning)by Green Mussels

Microalgae blooms have been frequently reported in the Jakarta Bay, which is also the location of green mussel (Perna viridis) aquaculture. Accumulation and depuration of Paralytic Shellfish Poisoning (PSP) toxin in the green mussels were investigated in the field, where the toxin accumulation studies conducted in the mussel farming at Cilincing, North Jakarta. Accumulation test carried out by placing back the selected green mussel (equal size) into the mussel farming. Every week for 2 months, the green mussel were collected from mussel farming and transported to the laboratory. The fitoplankton abundance also was checked including pH, Suhue and salinitiy paramaters. Toxin depuration was conducted at Clams Sanitation Unit at Panimbang Banten. The depuration studies were conducted for 24 hours with sampling every hour in the first 4 hours and every 3 and 2 hours until the 24th hour. Preparation, extraction and toxin concentration measurements performed by following the Manual AOAC Official Method 2005.06 for PSP toxin in oyster. This research concluded that the accumulation of PSP toxin by green mussel, Perna viridis in the mussel farming at Cilincing, North Jakarta in ranged between 4,11–11,96 μg STX eq. per 100 g during January–February 2011. No correlation between PSP toxin concentration in the green mussel, Perna viridis with abundance of the PSP toxin sources phytoplankton, because the study wasnt done when microalgae blooming. The depuration processes was eliminate 60% the PSP toxins for 24 hours depuration processing. It can be proposes as a banded system the PSP toxin from algae to human being.
