本文介绍了对斐济纳瓦卡武热带软体动物渔业崩溃和恢复进行逐种评估的结果。调查结果基于实地调查、照片记录、凭证标本收集、参与者观察以及过去和现在几代男女渔民的证词。结果显示，过去40年来，由于过度捕捞、破坏性捕捞技术和环境退化，几乎所有营养级的渔业资源都在退化，以及建立当地管理的海洋区和相关海洋保护区（当地称为“Vueti Navakavu”）的积极影响。自2002年成立以来，近300种软体动物，包括腹足类、双壳类和头足类，要么是40多年来首次出现，要么是丰度和/或大小级别明显增加。各种各样的锥壳（芋螺属）的丰度有了特别显著的增加，贝（宝螺属），海螺（Strombidae）、海螺（Muricidae）、螺旋螺（Terebridae）和头巾螺（Turbanidae），以及章鱼、鱿鱼和海兔，所有这些都具有经济、文化和生态重要性。研究结果表明，持续有效的海洋养护总体上可使严重退化的渔业、特别是热带软体动物区系得以恢复。这项评估突出了将最新的分类学和科学知识与老年渔民的知识相结合的价值，老年渔民对渔业变化有着长期的多鱼种知识。
This paper presents findings from a species-by-species assessment of the collapse and recovery of a tropical mollusk fishery in Navakavu, Fiji. The results are based on field surveys, photo documentation, collection of voucher specimens, participant observation, and testimonies of past and current generations of female and male fishers. The results show the degradation of fisheries resources at almost all trophic levels over the past 40 years due to overfishing, destructive fishing techniques, and environmental degradation, as well as the positive impacts of the establishment of a locally managed marine area (LMMA) and associated marine protected area (MPA), known locally as “Vueti Navakavu.” Since its establishment in 2002, nearly 300 mollusk species, including gastropods, bivalves, and cephalopods, are either being seen for the first time in over 40 years or are clearly increasing in abundance and/or size class. There has been a particularly dramatic increase in the abundance of a wide range of cone shells (Conus spp.), cowries (Cypraea spp.), conches (Strombidae), murexes (Muricidae), auger shells (Terebridae), and turban snails (Turbanidae), as well as octopus, squid, and seahare, all of which are of economic, cultural, and ecological importance. The results show that sustained effective marine conservation can, in general, lead to the recovery of seriously degraded fisheries and, in particular, of tropical mollusk fauna. This assessment highlights the value of synthesizing up-to-date taxonomic and scientific knowledge with the knowledge of older fishers, who have long-term multi-species knowledge of changing fisheries.
