[Prevalence of infections in marine fishes in Eastern Fujian Fishing Ground of Fujian Province].

OBJECTIVE

To investigate the prevalence of infection in marine fishes in Eastern Fujian Fishing Ground of Fujian Province, so as to provide insights into the development of the anisakiasis control strategy.

METHODS

Marine fish samples were randomly collected from Jiaocheng District, Fuding City and Xiapu County around Eastern Fujian Fishing Ground in Fujian Province from September to December, 2021. All fishes were dissected, and the abdominal contents were collected. Parasites were sampled under a stereomicroscope and the species were identified through morphology. The prevalence and intensity of infections were calculated.

RESULTS

A total of 177 marine fishes belonging to 24 species were dissected, and was detected in 73 marine fishes (41.2%) belonging to 16 species (66.7%), with a mean infection intensity of 14.3 parasites per fish. High prevalence of infection was found in (5/5), (3/3), (2/2), (12/13), (19/23), (6/11) and (14/27), with mean infection intensities of 9.2, 2.7, 4.5, 10.9, 39.2, 4.5 parasites per fish and 2.1 parasites per fish. The larvae were characterized as and

CONCLUSIONS

High prevalence of infection is detected in marine fishes in Eastern Fujian Fishing Ground of Fujian Province. The health education pertaining to food health is required to be reinforced to prevent the development of human anisakiasis.
