Why does it say “sprat” on the can, but “hamsa” or “tulka” in the can?

The term "sprat" is a general term used to describe a variety of small fish, such as herring, sardines, anchovies, and smelt. It is used to refer to the type of fish that is typically canned and sold in cans labeled "sprat." The specific species of fish in the can, however, may be different than what is indicated on the label. For example, a can labeled "sprat" may contain herring, sardines, anchovies, or smelt, but the label will not necessarily indicate which type of fish is inside the can. The terms "hamsa" and "tulka" refer to specific species of fish, such as herring and smelt, respectively. Therefore, the label on the can may indicate "sprat" as the general type of fish, but the specific species of fish in the can may be "hamsa" or "tulka."
