american seafood processing in America's oldest fishing port

Gloucester, a city with a rich fishing history dating back to 1623.

Located on the coast of Massachusetts, Gloucester Seafood Processing (GSP) is a purveyor and processor of premium American seafood. In 2014, Mazzetta Company purchased a vacant processing plant and began the arduous process of facility rebuilding. Extensive renovations to the entire infrastructure along with implementing modern processing equipment will ensure GSP meets & exceeds our customer’s expectations.

A completely updated facility combined with Mazzetta Company’s extensive knowledge of the seafood industry is an inspiring step forward for the company.

Extreme focus; dedication to product consistency and quality

What elevates our products, performance and customer service above the rest.

We have acquired valuable knowledge and experience from being involved for over a quarter century in the seafood industry. Here at GSP, those past lessons learned and knowledge gained are applied everyday in the way we source, process and package our fresh and frozen products. It starts with local, direct from the boat supply.

Once inside our plant, we plan and coordinate every step to ensure a smooth process. Expert filleters and trimmers cut fish by hand to preserve the natural beauty of each fish. Automatic portion cutters hit weight targets with extreme accuracy. Vac pac machines can wrap fillets and portions in clear or printed film, as well as trays. State of the art equipment freeze each piece of fish or lobster separately, resulting in a beautiful product that is easy for customers to select, prepare and serve.
