RESEARCH ON PARASITAR FISH PURITY AND FISH PRODUCTS (ACCORDING TO MATERIALS OF THE AGROCHEMICAL SERVICE)

Abstract

dead larva of Anisakis simplex was found in a sample of salmon caviar (chum). In all other cases, the result of parasitological research is negative. Summary. The most frequently positive findings were observed in frozen (34.9%) fish – metacercaria Rossicotrema donicum , Apophallus muehlingi and Posthodiplostomum cuticola and chilled (22.5%) fish-metacercaria Rossicotrema donicum and Apophallus muehlingi . In most cases (97%) in fish in the muscle and subcutaneous tissues were found metacercariae trematodes, dressed with black pigment. Metacercariae A. muehlingi were most often found in cyprinid fish (75.8%), and metacercariae R. donicum – in perch breeds (18.2%); in isolated cases – in pike (0.1%) were found metacercariae P. cuticola . Metacercariae were found in predatory fish (pike perch-15.2% and ASP-12.1%), as well as fish that live at the depth of reservoirs (bream-27.3% and tench-18.2%). The presence of A. simplex larvae in the caviar of salmon fish indicates poor-quality products of this type of canned food.
