To investigate the prevalence of infections in coastal marine fishes and awareness of anisakiasis control knowledge among local residents in Yantai City, Shandong Province in 2021, so as to provide insights into formulation of anisakiasis control interventions.
Marine fishes were purchased from Shunxin Port, Yantai City, Shandong Province in November 2021, and the presence of was detected in different species of fishes and different fish sites. The correlations between body length and weight of marine fish and intensity of infections were examined using Spearman's rank correlation analysis, and the dietary habits and anisakiasis control knowledge were investigated using questionnaire surveys among local residents.
A total of 201 marine fishes belonging to 20 species were dissected, and was detected in 77 marine fishes (38.31%) belonging to 11 species (55.00%), with a mean infection intensity of 45.04 parasites per fish (3 468/77). Spearman's rank correlation analysis revealed that the body length ( = 0.74, < 0.05) and weight ( = 0.79, < 0.01) of the monkfish correlated positively with the intensity of infections, and the body length ( = 0.68, < 0.05) of the flatfish correlated positively with the intensity of infections, while no correlations were examined between the body length or weight of other marine fishes and the intensity of infections. Of all respondents, 53.38% men and 56.67% women did not know anisakiasis control knowledge at all, and there was a significant difference in the proportion of respondents using separate chopping boards for raw and cooked food from different villages (χ = 17.89, < 0.01), while there was an age-specific proportion of respondents with habitats of eating raw or semi-raw seafood (χ = 28.27, < 0.01).
The prevalence and intensity of infections were high in coastal marine fishes in Yantai City in 2021, and the awareness of anisakiasis control knowledge was low among local residents. Intensified health education pertaining to anisakiasis control knowledge is recommended to reduce the risk of infections.
调查2021年山东省烟台市沿海海鱼中感染情况及当地居民对异尖线虫病防控知识的知晓率，为制定异尖线虫病防控干预措施提供依据。
于2021年11月从山东省烟台市顺新港购买海鱼，检测不同种类海鱼及不同鱼体部位的感染情况。采用Spearman等级相关分析检验海鱼体长、体重与感染强度的相关性，并通过问卷调查当地居民的饮食习惯和异尖线虫病防控知识。
共解剖20种201尾海鱼，在11种（55.00%）77尾海鱼（38.31%）中检测到感染，平均感染强度为每尾鱼45.04条寄生虫（3468/77）。Spearman等级相关分析显示，安康鱼的体长（r = 0.74，P < 0.05）和体重（r = 0.79，P < 0.01）与感染强度呈正相关，比目鱼的体长（r = 0.68，P < 0.05）与感染强度呈正相关，而其他海鱼的体长或体重与感染强度之间未检测到相关性。在所有受访者中，53.38%的男性和56.67%的女性对异尖线虫病防控知识一无所知，不同村庄受访者使用生熟分开案板的比例存在显著差异（χ² = 17.89，P < 0.01），而有生食或半生食海鲜习惯的受访者比例存在年龄差异（χ² = 28.27，P < 0.01）。
2021年烟台市沿海海鱼感染率和感染强度较高，当地居民对异尖线虫病防控知识知晓率较低。建议加强异尖线虫病防控知识的健康教育，以降低感染风险。
