Toxicity of the Goby, Gobius criniger

Abstract

Specimens of Gobius criniger, collected from the Ryukyu and Amami Islands and from Formosa, were examined for their toxicity by a mouse assay. They showed a great regional variation of toxicity and an indistinct seasonal one. The individual variation in the specimens collected at the same time at the same place was very small. In the toxic specimens, the skin was generally high in toxicity, followed by the viscera and muscle in that order. In a few specimens the highest toxicity was in the mature testes.
