【Abstract】 OBJECTIVE?To investigate the infection status of anisakid larvae in marine fish and cephalopods from the Bohai Sea.?METHODS?The infection status of anisakid larvae were examined by autopsy in 290 marine fish of 25 species and in 108 cephalopods of 3 species.?RESULTS?A total of 7?327 larvae was collected from 156 fish of 19 species and 8 squids of one species.
