Owing to its large coastline along three oceans, Russia maintains one of the world's largest fishing fleets, ranking sixth in the world in tonnage of fish caught; capturing 4,773,413 tons of fish in 2018. It is also home to the world's finest caviar (the beluga), and produces about one-third of all canned fish, and some one-fourth of the world's total fresh and frozen fish.
