Shellfish aquaculture is still fairly new to the United States, but this field is growing at a fast pace in some New England states. As the Gulf of Maine becomes warmer in temperature due to climate change, the potential to grow northern quahogs (Merceneria merceneria) in an aquaculture setting in the state of Maine is beginning to arise. This study seeks to understand one project taking place at Winnegance Oyster Farm in West Bath, Maine, which tests crop diversification by growing oysters and quahogs in the same location. Three questions were examined:, 1) how does location (surface vs. bottom) affect quahog growth in terms of shell length, 2) how do different seasons affect quahog growth in terms of shell length, and 3) how does location affect quahog mortality? We found that location was not a significant factor in terms of quahog growth, but the season in which the quahogs grew and were measured was a significant factor. Furthermore, we found that location did have a significant influence on the mortality of quahogs. Overall, these findings suggest that this project offers a promising future for shellfish aquaculture in Maine but more research should be conducted to make conclusions on whether this type of aquaculture method is viable and sustainable into the future.
