Fish biomass and density data for 3 intensively studied Wessex chalkstream sites, England, UK

Density and biomass of fish taxa from three chalkstreams in the Wessex chalk area: Nine Mile River, River Till and River Wylye. Data were collected on five occasions, between October 2012 and October 2013. The density of fish taxa at each of the three streams was estimated using benthic fish sampling and multi-pass electrofishing. The mean biomass of individuals of each taxon at each site on each occasion was then applied to the density estimates to derive an estimate of the biomass per m2 of each taxon at each site on each occasion. Data were collected to quantify food webs detailing the flux of mass and nutrients between nodes of the food web. This dataset was created as part of work package 3.2 of the Wessex Biodiversity & Ecosystem Service Sustainability (BESS) project.

关于韦塞克斯白垩地区三条白垩溪流（九英里河、提尔河和怀利河）中鱼类分类的密度和生物量：数据收集于2012年10月至2013年10月期间的五次事件。通过底栖鱼类采样和多遍电捕捞法，对三条溪流中鱼类分类的密度进行了估算。随后，将每个地点每次事件中每个分类个体的平均生物量应用于密度估算，以得出每个地点每次事件中每个分类的生物量每平方米的估计值。此外，收集数据以量化食物网，详细描述食物网节点之间质量和营养物质的流动。本数据集作为韦塞克斯生物多样性及生态系统服务可持续性（BESS）项目第三工作包3.2的成果而创建。关于本数据集的详细信息，请参阅https://doi.org/10.5285/7eee41f8-dbde-4b5e-b2d5-7296b5bfc558。
