We address the economic impacts of the role of Biodegradable Fishing Gear (BFG) as a mitigation measure for the ghost fishing impact of lost fishing gear, through scenarios based on industry interviews. We find that the use of BFG is a technical challenge and not an economic problem. The majority of costs to fishermen in terms of BFG use are not related to investment and maintenance costs rather the impact of reduced fishing efficiency. At the Channel static gear fishery level, we estimate the costs of implementing BFG to be as high as £8 million. If the issue of fishing efficiency was resolved (i.e. BFG was a like-for-like) then the large negative costs could be overturned to between a cost of £880,000 and a small positive benefit of around £150,000. Considering the negative environmental impacts of lost gear, the benefits of BFG use over traditional fishing gear would grow exponentially.
我们通过基于行业访谈的情景分析，研究了可生物降解渔具（BFG）在减轻渔具丢失造成的幽灵渔具影响方面的经济作用。我们发现，BFG 的使用是一个技术挑战，而不是经济问题。从渔民的角度来看，使用 BFG 的大部分成本与投资和维护成本无关，而是与降低捕鱼效率的影响有关。在海峡定置渔具渔业中，我们估计实施 BFG 的成本高达 800 万英镑。如果解决了捕鱼效率的问题（即 BFG 与传统渔具一样），那么巨大的负面成本可能会转变为 88 万英镑的成本和 15 万英镑的小收益。考虑到丢失渔具的负面环境影响，BFG 的使用相对于传统渔具的好处将呈指数级增长。
