Abstract

The aim of this work is to evaluate how changes in a set of different key operational factors (e.g., the unit sales price, the fingerling unit cost, the feed unit cost, and so on) would impact on the economic performance of a typical grow-out farm producing European sea bass in the Mediterranean under different scenarios of production related to the farm size (production volume) and production strategy (size of the produced fish). A what-if analysis using a deterministic static model to simulate the annual income statement of a typical grow-out farm was carried out. Data was obtained from ten European facilities located in the Mediterranean Sea. Our findings show the importance of the farm’s scale and the production of larger fish to obtain better economic results. Another important conclusion is that increase in fish growth and survival rates, innovating in feed and improving the breeding and health conditions, could compensate the reductions in the sea bass sales prices more efficiently than using other alternatives.

摘要

这项工作的目的是评估一组不同的关键运营因素（例如，单位销售价格、鱼种单位成本、饲料单位成本等）的变化将如何影响典型增长的经济绩效- 在与农场规模（产量）和生产策略（生产鱼的大小）相关的不同生产情景下，在地中海生产欧洲鲈鱼的农场。使用确定性静态模型模拟典型养成农场的年损益表进行假设分析。数据来自位于地中海的十个欧洲设施。我们的研究结果表明，养殖场的规模和大型鱼类的生产对于获得更好的经济结果非常重要。另一个重要的结论是鱼类生长和存活率的提高，
