People know canned fish as “tuna”, which is a misnomer because canned fish can be made from different types of fish; For example, until a few years ago, canned sardines and kilka were on the market, but they were no longer produced because they were not well received. In our country, canned tuna has many fans. “Tuna” is not the name of a type of fish, but the name of a large group of fish.
