Massachusetts Congressman and candidate for Senate Edward Markey has introduced legislation intended to the fight the widespread mislabeling of seafood.

    Rep. Markey filed the bill Wednesday in response to studies that show seafood is mislabeled as much as a third of the time in restaurants and retail outlets, such as supermarkets.

    Markey said his bill aims to make ``the entire seafood supply chain more transparent and trustworthy.''

    The bill aims to ensure that information about domestic and imported fish, such as its species and where it was caught, follow the fish from boat to market.

    It also tries to establish civil penalties for violators and strengthen the ability of federal regulators to stop fraudulent seafood shipments from entering the country.
