Description
This dataset contains 85,933 individual records of length measurements for 112 freshwater fish species collected from Cambodian inland freshwater ecosystems. The data can be used to establish length-length models that can be applied to standardized length measurements in support of fisheries biology, ecological studies, and fish stock assessment. Measurements include total length (TL), standard length (SL), and fork length (FL), reported in centimeters (cm).
Sampling
Fish were sampled across the upper Mekong–3S River system, Tonle Sap Lake, and Tonle Sap River using arrow-shaped traps, the dai fishery, stationary gillnets, and samples from local landing sites and markets. Sampling was conducted during 2020–2021 and covered both wet and dry seasons. Each record represents one individual fish.
