For frozen fish and dried fish, the trademark can be printed on the packaging bag. If it is live fish, the trademark can be printed on the billboard at the point of sale or on the container of live fish without hanging the trademark. On the fish. Trademarks only play a role in distinguishing the source of goods during sales. Fish is food and is imported directly, so there is no need to display a trademark. For example, for products such as bare chicken and chicken drumsticks, the trademarks are printed on the packaging.
