Coral reef ecosystems are facing unprecedented natural and human-induced pressures. However, the primary driver of the decline in coral reef fish abundance and diversity is overfishing of fish stocks. Despite this, fish is the primary protein source for many humans living in Fiji and surrounding Pacific Islands. Therefore, striking a balance between managing reef fisheries sustainably whilst feeding a growing population is critical. As such, understanding the impact of fisheries on coral reef biodiversity will be important for informing best practice management. In Fiji, fisheries have complex socio-economic and ecological dynamics. Thus, research requires a multi-pronged and holistic approach to quantify ecological impacts, whilst understanding associated community and governance perspectives. This project will align with the Biome Health Project to create a robust fishing pressure gradient. It will achieve this by employing video photogrammetry to quantify reef fish diversity, abundance, size structure, biomass and behavioural traits. This will be interwoven with local community knowledge of by applying social science techniques and together will contribute to the marine spatial planning process being undertaken in Fiji. By using an interdisciplinary methodology this project aims to advise on the management of local fisheries, therefore, having both ecological and applied components.

珊瑚礁生态系统正面临着前所未有的自然和人为压力。然而，珊瑚礁鱼类丰度和多样性下降的主要驱动因素是鱼类资源的过度捕捞。尽管如此，鱼类仍然是生活在斐济和周围太平洋岛屿的许多人的主要蛋白质来源。因此，在可持续地管理珊瑚礁渔业和养活不断增长的人口之间取得平衡至关重要。因此，了解渔业对珊瑚礁生物多样性的影响将对最佳实践管理提供重要信息。在斐济，渔业具有复杂的社会经济和生态动态。因此，研究需要一种多管齐下的整体方法来量化生态影响，同时了解相关的社区和治理观点。该项目将与生物群落健康项目保持一致，以创造一个强大的捕捞压力梯度。它将通过视频摄影测量来量化珊瑚鱼的多样性、丰度、大小结构、生物量和行为特征，从而实现这一目标。这将通过应用社会科学技术与当地社区知识相结合，并将共同促进斐济正在进行的海洋空间规划进程。通过使用跨学科的方法，该项目旨在就当地渔业的管理提供咨询意见，因此具有生态和应用两个组成部分。
