... is another significant producer of hard clams with 15% of U.S. production value, but no cost data from Connecticut were available for this analysis. Table 7 provides the summary economic impacts for clam aquaculture. One thing that stands out immediately is that as currently practiced, clam aquaculture is nowhere near as labor intensive as oyster aquaculture; it is more similar in labor utilization to crawfish production. ...Similar publications

... The Virginia Institute of Marine Science (VIMS) has previously included REAs within their annual shellfish aquaculture situation and outlook report (Murray & Hudson, 2013), but has since focused primarily on revenue and production statistics (Hudson, 2019). In addition, a recent collaborative study by NOAA and the University of Maryland estimated the economic contributions of crawfish, salmon, clam, and other aquaculture in the U.S. using publicly available data (Lipton et al., 2019). This particular study highlighted a number of data issues addressed in this research and went as far as to outline the information that would be needed to accurately estimate the economic contributions of U.S. aquaculture production on an annual basis. ...
... For the reasons previously mentioned, aquaculture REAs have struggled with both holistic and partitive accuracy (Lipton et al., 2019). 5 Additionally, it is difficult to achieve holistic accuracy without a tailored data collection process. ...
... The direction and magnitude of differences between the "Built-in model" and the "Hybrid model" can vary over time as the overall economic structure of the region changes and can vary by region and type of aquaculture even in the same time period. Use of the "Hybrid model" method can help combat aggregation bias inherent in the use of "Built-in model" methods for economic contribution analyses for U.S. aquaculture sectors (Lipton et al., 2019). Improvements in annual aquaculture production data will also increase the accuracy of total economic contribution estimates; however, because the IO model is a system of linear equations, changes in the overall value of shellfish aquaculture with which we drive results will not change the nature of the differences between the two methods. ...
Regional economic assessments (REAs), including economic contribution and impact analyses, are often used in resource-based industries to inform policymakers, elected officials, and the general public of an industry’s role within the regional economy. However, REAs have been difficult to conduct for the aquaculture industry due to issues with data availability and quality. This paper will provide an overview of economic contribution analysis, the challenges associated with applying these analyses to U.S. aquaculture production, and techniques to overcome these challenges. The Florida shellfish aquaculture industry is used as an example to highlight some of the data issues and how using different methods within a REA can lead to inaccurate representations of an industry’s economic contribution.
