Ichthyotoxicity of Paralytic Shellfish Poison
Attempts were made to examine the ichthyotoxicity of paralytic shellfish poison (PSP) in sixteen species of marine and freshwater fishes. Most of them showed minimum lethal doses (LD100) ranging from 1-8 MU/20g body weight when injected with a partially purified PSP intra peritoneally. Exceptionally, several fishes such as a goby Acanthogobius flavimanus (LD100, 9-17 MU/20g) and puffer Fugu nip...

متن کاملParalytic shellfish poison, the primary source of the poison, the marine plankton organism, Gonyaulax catenella.
Shellfish, such as clams, mussels, and oysters, feed on marine plankton. At least one species of dinoflagellate, Gonyaulax catenella Whedon and Kofoid, has been shown by Sommer and coworkers (1) to be a source of the poison found in the California mussel, Mytdus californianus Conrad. The present investigation was carried out to determine the feasibility of collecting the plankton and extracting...
متن کاملParalytic Shellfish Poisoning Toxins: Biochemistry and Origin
Plankton feeders such as bivalves often become toxic. Human consumption of the toxic bivalve causes severe food poisoning, including paralytic shellfish poisoning (PSP) which is the most dangerous because of the acuteness of the symptoms, high fatality and wide distribution throughout the world. Accumulation of PSP toxins in shellfish has posed serious problems to public health and fisheries in...
متن کاملParalytic Shellfish Poisoning: Effects on Breeding Terns
-More than 70 Common Terns (Sterna hirundo) and lesser numbers of other terns and gulls were killed on 1 l-l 2 June 1978, by Paralytic Shellfish Poisoning (PSP; toxin of the dinoflagellate Gonyaulax excavata) at a breeding colony in Massachusetts. PSP toxin was detected at lethal levels in sand-launce (Ammodytes americanus), the terns’ principal food. Almost all terns that died were females in ...
