Canned fish
Canned fish refers to fish that has been processed, sealed in an airtight container such as a tin can, and subjected to heat to preserve it for long-term storage. This method of preservation allows fish to be stored and consumed over extended periods without refrigeration.
History[edit]
The practice of canning fish dates back to the early 19th century. Nicolas Appert, a French chef, is credited with developing the canning process, which was later adapted for fish. The first commercial canning of fish began in the early 1800s, with sardines being one of the first types of fish to be canned.
