Assays were made for paralytic toxicity of marine invertebrates inhabiting at the coasts of Hiroshima Bay, where the infestation of bivalves such as cultured oysters with paralytic shellfish poison (PSP) has been occurred. The starfish Asterina pectinifera collected at the estuary of Nikoh River, Hiroshima Bay, was found to contain moderate levels of paralytic toxicity. Its highest toxicities as PSP found on July 30, 1999 were 12.5 MU/g for whole body, 11.0 MU/g for integument tissues and 3.9 MU/g for viscera, respectively. The toxicity of integument was changed from 3.6 to 11.0 MU/g in 1 year. Its paralytic toxin principles were identified as PSP toxins, composing mainly from saxitoxin (STX) group toxins such as carbamoyl-N-hydroxy neosaxitoxin (hyneoSTX), and STX, by HPLC and LC-MS, accounting for over 90 mol%. The PSP toxins contained in the starfish A. pectinifera considered to be transferred from bivalves or detritus living in the same area, which were contaminated with PSP. However, the involved pathway may be different from that of Asterias amurensis which was infested directly through food chain from its food bivalves, for its toxin pattern.
