[Rates of infection of fishes from Okhotsk sea with human Anisakidae].

In 1987 to 1999, large-scale studies were conducted in the Okhotsk Sea basin for marketable fish infection with Anisakidae larvae that are a hazard to human health. A total of 9223 fishes of 18 species and 455 fishes of 5 species were examined in the North and South-West Okhotsk Sea Regions, respectively. In the North Okhotsk Sea Region, the larvae were detected in 58.8 (0.5% specimens of all species with the highest rates in the rasp (100%), Siberian salmon 93.9 (0.8%), herring 91.2 (0.7%), silver 90.9 (1.6%), halibut 89.7 (3.1%), Greenland halibut 87.3 (4.2). In the South-West Okhotsk Sea Region, the total fish infection rates were 69.8 (2.6%) and those of the commonly caught species Siberian salmon and humpback were 82.8 (3.3 and 67.9 (3.6%), respectively. The infection rates varied both at the inter- and intraspecies-specific levels, as well in areas and fishing seasons. Fresh fish processing (freezing and salting) causes no Anisakidae larval migration in the flesh.
