Rapana in the Sea of Azov: Growing stock as a basis for future fisheries in Russia

Published 2024년 11월 14일

Tridge summary

The Azov Sea is experiencing increased rapana mollusk populations due to changes in freshwater runoff and salinity levels. This mollusk, which now inhabits nearly all of the sea's water area, could provide a significant source of employment for Russia's small fishing fleet and serve as a protein and nutrient source for the feed industry. Research has shown that rapana meat has a low fat content and high protein content, with all essential amino acids. Standards for the production of rapana products, including chilled and frozen meat, canned goods, and various canned fish options, have been developed. Additionally, the use of rapana shells as a poultry feed supplement has been suggested.

Changes in freshwater runoff and increased salinity affect the sea ecosystem, which has led to a significant increase in the number of rapana. This mollusk now lives in almost the entire water area of the Azov Sea. According to research, rapana has spread not only to the Kerch Strait, but also to other areas of the sea with a salinity of 14.9 to 15.3‰. Scientists emphasize that this mollusk can become one of the key alternatives for ensuring employment of small fishing fleet in Russia. Rapana is also considered as a source of protein and nutrients for the feed industry. According to its nutritional characteristics, rapana has high nutritional value: the fat content in meat is only 0.2-0.4%, and protein is 15-21%. The protein contains all the essential amino acids. Standards have been developed for rapana products, including technical conditions for chilled and frozen ...
