Global aquaculture markets have experienced a great deal of recent success. However, growers are still highly susceptible to risks caused by seasonality, interannual variability in earnings, and environmental factors. As a result, we see growers turning to alternative sources of income, and participating in off-farm labor. We utilize a series of zero-inflated count models to examine the relationship between an aquaculture grower's off-farm labor decision and relevant explanatory variables including demand-side potency, which is often omitted in the literature. We also look to identify and analyze the importance of professional social networks among growers as a stabilizing mechanism and a way to mitigate risk to growers. This study expands upon an economic model that has traditionally been used for analyzing off-farm labor choices within an agricultural context and applies it to an increasingly important industry, aquaculture.

水产养殖业的非农就业：新英格兰牡蛎种植者的案例研究

全球水产养殖市场最近取得了巨大的成功。然而，种植者仍然很容易受到季节性、收入的年际变化和环境因素引起的风险的影响。因此，我们看到种植者转向其他收入来源，并参与非农劳动力。我们利用一系列零膨胀计数模型来检查水产养殖者的非农劳动力决策与相关解释变量（包括需求方效力）之间的关系，这在文献中经常被忽略。我们还希望识别和分析种植者之间的专业社交网络作为稳定机制和减轻种植者风险的方式的重要性。
