Many species of fish are venomous and poisonous to man. Venomous fish produce toxic substances that can be inoculated during stings or bites. Some fish with a cartilaginous skeleton (stingrays) live on sandy bottoms and most injuries occur when bathers, waders, or fishermen accidentally step on their bodies, when they will arch their tails and project the spine violently against the victim’s legs. Local pain is immediate and very severe: it is acute, throbbing or piercing and lasts 1-2 days. General symptoms, involving the cardiocirculatory, gastroenteric and muscle systems, can even be fatal. Weeverfish, that have spines on various parts of the body, are among the most dangerous venomous fishes. Accidental contact with these fish causes a very severe reaction that may be fatal due to cardiac arrest. Contact with the spines of scorpionfish, among the most numerous and geographically widespread toxic fishes, also causes anguishing pain and very serious systemic symptoms, that can again be fatal. The bites of moray eels, too, cause intense local pain and serious systemic signs; occasionally, when harpooned, the battle between the fisherman and a large animal can have fatal consequences. The possible shock due to contact with a fish with an electric apparatus is not generally strong enough to cause skin or nerve lesions, apart from a state of stupor that could be dangerous during emersion procedures. Passively toxic fish, that do not produce toxins but acquire them from the environment, are poisonous only when eaten and can cause various serious poisoning syndromes (ciguatera fish, tetrodotoxic and scombrotoxic poisonings).

Abstract

Many species of fish are venomous and poisonous to man. Venomous fish produce toxic substances that can be inoculated during stings or bites. Some fish with a cartilaginous skeleton (stingrays) live on sandy bottoms and most injuries occur when bathers, waders, or fishermen accidentally step on their bodies, when they will arch their tails and project the spine violently against the victim’s legs. Local pain is immediate and very severe: it is acute, throbbing or piercing and lasts 1-2 days. General symptoms, involving the cardiocirculatory, gastroenteric and muscle systems, can even be fatal. Weeverfish, that have spines on various parts of the body, are among the most dangerous venomous fishes. Accidental contact with these fish causes a very severe reaction that may be fatal due to cardiac arrest. Contact with the spines of scorpionfish, among the most numerous and geographically widespread toxic fishes, also causes anguishing pain and very serious systemic symptoms, that can again be fatal. The bites of moray eels, too, cause intense local pain and serious systemic signs; occasionally, when harpooned, the battle between the fisherman and a large animal can have fatal consequences. The possible shock due to contact with a fish with an electric apparatus is not generally strong enough to cause skin or nerve lesions, apart from a state of stupor that could be dangerous during emersion procedures. Passively toxic fish, that do not produce toxins but acquire them from the environment, are poisonous only when eaten and can cause various serious poisoning syndromes (ciguatera fish, tetrodotoxic and scombrotoxic poisonings).
