Данные проекта

The dataset contains records of aquatic fauna (mainly fishes) collected in the River Tua and its tributaries Tuela and Tinhela, as well as in the rivers Torto, Távora, Tedo and Pinhão in the Douro river basin within the Compensatory Measures Program (2017-2027) of the Exploitation Phase of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected in the spring 2017 in 24 sampling stations distributed along the concerned rivers. The occurrence of the target taxa was documented through 665 records of individuals. The most abundant fish species (>100 records) were Pseudochondrostoma duriense (178 individuals), Luciobarbus bocagei (159), Squalius carolitertii (145) and Squalius alburnoides (103). Other taxa seen/captured were larval stages of Insecta (Orders Plectoptera, Ephemeroptera and Trichoptera) (22 individuals/observations) and Galemys pyrenaicus (3 individuals/observations).

Методы сбора

The harvesting at each location were carried out using electric fishing, based on standardized procedures (INAG, 2008). The fishes’ captures were carried out against the current, in the downstream-upstream direction, involving a team of four elements, including an operator of the electric fishing net, an assistant with a hand-held net to collect individuals, and two assistants to ensure safety and help in sample processing. In each location, a river section of about 50-100m in length was prospected, and individuals of the target species captured were kept. Priority was given to adult individuals of each species, collected as much as possible from different points of the river, in order to reduce the risk of collection of related individuals who could introduce bias in the genetic analyses. From each individual, a small portion of tissue from the dorsal fin was cut, stored in an eppendorf tube with ethanol analysis (96%) and properly labeled. Each individual was also measured (total length) and photographed. Collection methods and conservation have already been properly tested in previous works by CIBIO-InBIO. At the end of the campaign, the samples collected were kept in stable temperature conditions, stored and transported to the laboratory. The locations of all samples were georeferenced with the aid of a GPS device and subsequently processed in a GIS environment.
