摘要Identifying and evaluating potentially suitable tools to assess the status of cetaceans in coastal waters with high
levels of anthropogenic threat represents a first step towards effective conservation management. Local ecolo-
gical knowledge (LEK) can often provide more extensive information on focal species and biological resources
than is available from standard ecological surveys, and is increasingly recognized as an important source of data
for conservation research and management, but it has rarely been used as a tool to assess the status of cetaceans.
We investigated the efficacy of using LEK from local fishers combined with stranding records to characterise the
diversity and distribution of coastal cetaceans in the northern South China Sea, a region with high historical
levels of cetacean abundance and diversity but which is experiencing intensifying anthropogenic pressures.
Fishers were unable to identify most regionally occurring cetaceans to species level. However, we were able to
determine the distributions of eight categories of cetaceans that were observed by fishers, and a previously
unknown population of Indo-Pacific humpback dolphin reported from the coastal waters of Hainan that was later
confirmed through boat-based surveys. The number of sightings of different cetacean categories reported by
fishers has a significant positive linear relationship with independent data on numbers of stranded cetaceans,
validating the accuracy of our respondent data and indicating that LEK can provide useful, quantitative in-
formation on abundance rankings of different cetacean categories.
