有害藻华（HABs）对贝类养殖部门的经济影响取决于其频率、持续时间和强度。保护储存和加速解毒是可以减轻这些事件影响的技术解决方案。本文首先分析了法国贝类养殖部门可以采用的技术变革的经济可行性。然后研究它们相关的社会影响。最后，在勃艮第湾产区进行了应用。经济分析解决了与有害藻华有关的三个问题：(1)Bourgneuf湾贝类养殖场的经济效益，(2)这些新技术的成本，(3)这种投资的经济可行性。结果表明，只有少数经济上可行的农场能够实施这些技术，但这并不适用于规模较小、利润较低的农场。考虑到对技术设备的需要，在“自由放任”的公共政策范围内的个人行动将导致该部门的集中，有利于最大的资本主义农场，对就业和经济租金的分配产生不利影响。实施这些技术变革的其他方法需要集体行动或公众支持。
The economic impacts of harmful algal blooms (HABs) on the shellfish farming sector depend on their frequency, duration and intensity. Safeguarding storage and accelerated detoxification are technical solutions that could mitigate the effects of these events. This article first analyzes the economic feasibility of the technological changes that can be adopted by the shellfish farming sector in France. It then examines their associated social impacts. Finally, an application is carried out on the Bourgneuf Bay production area. The economic analysis addresses three issues related to HABs: (1) the economic performance of the shellfish farms in Bourgneuf Bay, (2) the costs of these new technologies, and (3) the economic viability of such an investment. Results suggest that only a few economically viable farms would be able to implement these technologies, yet this would not be an option for smaller, less profitable farms. Individual action within the context of a “laissez-faire” public policy, taking into account the need for technological equipment, would result in a concentration of the sector to the benefit of the largest capitalist farms, with negative effects on employment and the distribution of economic rent. Alternative ways for implementing these technological changes would require collective actions or public support.
