A receipt showing the weight of fish constitutes a weigh master's certificate when issued by whom?

A receipt showing the weight of fish constitutes a weigh master's certificate when issued by a licensed individual. This is because the individual must have the appropriate credentials and training to accurately measure and certify the weight of fish. A licensed weigh master is recognized as having the authority and expertise necessary to ensure that the weight recorded is accurate and complies with regulations. This certification is important for maintaining standards in trade, especially in industries like fishery where weight plays a critical role in pricing and regulation.

Other options might suggest individuals who have some connection to the sale or distribution of fish, but without the specific licensing required to verify and certify weights, their documentation would not have the same legal standing or accountability as that issued by a licensed individual.
