Location
Great Gun oysters are cultivated in Moriches Bay on Long Island, New York. Moriches Bay sits on Suffolk County’s South Shore between the Moriches Inlet and the Great South Bay. This sheltered estuary offers environmental factors that support oyster growth and prosperity.
The farm’s proximity to Moriches Inlet provides a constant flow of water rich in plankton and algae. These nutrients are essential food sources for oysters. This environment contributes to rapid growth, sometimes reaching market size in nine months. The usual harvest window runs 12 to 18 months.
The bay’s connection to the Atlantic Ocean creates a dynamic ecosystem that benefits oyster cultivation. Higher salinity levels contribute to the oyster’s distinctive flavor profile. Steady tidal exchange also keeps the farm flushed with fresh seawater.
The Farms Design
Paul McCormick’s floating farm design places oysters at the top of the water column where food is most abundant. The farm uses suitcase-style mesh bags that expose one side to the sun. That exposure keeps bag surfaces clean without harsh treatment. High-quality seed from Aeros Cultured Oyster Company rounds out the growth program.
The farm’s location along the Fire Island National Seashore offers protection from extreme weather. It still allows enough water movement for ideal cultivation. Oysters here also filter the bay and improve local water quality. That balance supports both farm productivity and ecosystem health.

At full capacity, Great Gun’s oysters can filter up to 15 million gallons of water daily. They remove excess nitrogen and convert it into a safe byproduct. This natural filtration helps keep algae blooms in check. It demonstrates the symbiotic relationship between the farm and Moriches Bay.
