چکیده
AIM There is little information about the prevalence of Corynosoma caspicum in fish particularly Gasterosteus aculeatus in Iran and the world. The aim of the present study was to find out the prevalence of acanthocephalan infection in Babolsar district, southern coastal of Caspian Sea, Northern Iran. MATERIALS AND METHODS Between September 2012 and August 2014, a total of 360 G. aculeatus fishes were randomly collected by drift nets from coastal regions in Babolsar and then examined the intestine and body cavity for worm infections. RESULTS A total of 360 G. aculeatus fishes, 109 (30.3%) were found infected with at least one Corynosoma capsicum, and there was no significant association between genders and the prevalence infection of acanthocephalan. Moreover, there was a significant difference in infected rate between summer (79%, 86/109) and spring (21%, 23/109) (p<0.05). CONCLUSION The high occurrence of Corynosoma infection in G. aculeatus indicates the enzootic constancy status of the infection in the southern coastal of Caspian Sea, Northern Iran.
