Multi-use marine protected areas (MPAs) are increasingly designated towards achieving global conservation targets. To develop effective management, the impact of permitted activities must be understood. Potting for shellfish occurs on temperate rocky reefs globally with impact not fully quantified. This UK-based study used underwater video to quantify (a) benthic condition of rocky reefs, (b) mechanisms of potting interaction and (c) true footprint of potting. Assemblages in static gear areas were more indicative of a healthy reef than those in mixed gear areas. Damage was recorded during pot hauling, but the area of damage was not the entire pot haul path. 25–30% of individuals were damaged (commonly through tissue abrasion) or removed. Notably, damage occurred to some long-lived, slow growing taxa raising concerns over impacts. Potting is more destructive than previously thought and managers must balance ecology with social and economic considerations to determine what level of impact is acceptable.

越来越多地指定了多用途海洋保护区（MPA）以实现全球保护目标。为了发展有效的管理，必须了解允许的活动的影响。在全球温带岩石礁石上进行贝类灌装，其影响尚未完全量化。这项基于英国的研究使用水下视频来量化（a）礁石的底栖条件，（b）盆栽相互作用的机制和（c）盆栽的真实足迹。与混合齿轮区域相比，静态齿轮区域中的组件更能指示珊瑚礁健康。拖运过程中记录了损坏情况，但损坏区域并非整个拖运路径。25–30％的个体被损坏（通常是通过组织擦伤）或被去除。值得注意的是，一些寿命长，增长缓慢的分类单元发生了损坏，引起了人们对影响的担忧。
