Abstract

Availability of new oyster production methods offers a variety of choices for oyster farmers that include the overall business model, marketing strategy, scale of production, and the production method. Cost structures and relative profitability vary across production methods, scales, and business models. Maryland oyster farms were used as the basis for an assessment of the relative economic tradeoffs among traditional and newer, more intensive, production methods based on farm-level data. Oyster farmers in Maryland were interviewed in 2018 and 2019 to collect data from farm records on expenditures, prices, investment in equipment and facilities, and common problems. Production method/scale categories identified included annual production levels of ≤200 bushels and >200 bushels for traditional bottom culture and ≤6,000 and >6,000 boxes (100-count) for container culture. Cost structures were identified for each category, and accounting and economic net returns (profit) calculated for each (in $/bushel for traditional bottom culture and $/box for container culture). Stochastic dominance for profitability was assessed across the four farming categories. Cost structures differed substantially across the four categories, with fuel the greatest expense for traditional bottom culture farms and labor, followed by marketing costs, the greatest expenses for container culture farms. All categories were profitable based on accounting net returns, but only the large-scale farms for each production method were profitable in terms of economic net returns. The most profitable category was the large-scale container culture category followed by the large-scale bottom culture category, but the larger traditional bottom culture category was the least risky (by first-order stochastic dominance). Risk was substantially greater for the larger container culture category and for the smaller bottom culture category. Continued Extension support is needed to provide assistance with comprehensive business financial planning and risk mitigation (including efforts to reduce yield variability), especially for startup farms seeking to grow to provide full-time salaries for owners/operators.
