Exiting the EU allows the UK to unilaterally change the frameworks that govern its environment and natural resources. This opportunity is timely given the urgent need to address the biodiversity and climate emergencies, and deliver the necessary policy changes to meet associated international agreements. The UK's divergence from EU environmental policy has already begun. The new Agriculture Act uses the concept of “public money for public goods” (PMPG) to seemingly revolutionise direct agricultural subsidies, replacing the much-maligned funding mechanisms under the Common Agricultural Policy and making the provision of their replacement dependent upon actions delivering societal gain. However, the potential benefits of transposing this concept to marine fisheries and aquaculture are yet to be recognised despite similar criticisms of funding mechanisms under the Common Fisheries Policy. This paper therefore considers the key distinctions between our use of marine and terrestrial environments and how PMPG could be applied to fisheries and aquaculture. The findings suggest that some forms of aquaculture are well-placed to benefit from a ‘marinising’ of the PMPG concept. Currently, capture fisheries, because they do not have ownership over marine space and interact with the marine environment in an extractive manner, have a greater challenge to adapt their business models to receive public money under this framework.

退出欧盟允许英国单方面改变管理其环境和自然资源的框架。鉴于迫切需要解决生物多样性和气候紧急情况，并提供必要的政策变革以满足相关的国际协议，这个机会是及时的。英国与欧盟环境政策的分歧已经开始。新农业法案使用“公共物品公共资金”（PMPG）的概念似乎彻底改变了直接农业补贴，取代了共同农业政策下饱受诟病的筹资机制，并使替代方案的提供取决于带来社会收益的行动. 然而，尽管对共同渔业政策下的筹资机制提出了类似的批评，但尚未认识到将这一概念应用于海洋渔业和水产养殖的潜在好处。因此，本文考虑了我们对海洋和陆地环境的使用以及如何将 PMPG 应用于渔业和水产养殖之间的主要区别。研究结果表明，某些形式的水产养殖可以很好地受益于 PMPG 概念的“海洋化”。目前，捕捞渔业由于不拥有海洋空间的所有权并以采掘方式与海洋环境相互作用，因此在调整其商业模式以在此框架下接收公共资金方面面临更大的挑战。因此，本文考虑了我们对海洋和陆地环境的使用以及如何将 PMPG 应用于渔业和水产养殖之间的主要区别。研究结果表明，某些形式的水产养殖可以很好地受益于 PMPG 概念的“海洋化”。目前，捕捞渔业由于不拥有海洋空间的所有权并以采掘方式与海洋环境相互作用，因此在调整其商业模式以在此框架下接收公共资金方面面临更大的挑战。因此，本文考虑了我们对海洋和陆地环境的使用以及如何将 PMPG 应用于渔业和水产养殖之间的主要区别。研究结果表明，某些形式的水产养殖可以很好地受益于 PMPG 概念的“海洋化”。目前，捕捞渔业由于不拥有海洋空间的所有权并以采掘方式与海洋环境相互作用，因此在调整其商业模式以在此框架下接收公共资金方面面临更大的挑战。
