LTER Baixo Sabor: Long term monitoring of freshwater fish - Sabor watershed [2012 - 2020]. Version 1.3. CIBIO (Research Center in Biodiversity and Genetic Resources) Portugal. Sampling event dataset https://doi.org/10.15468/pep8ma accessed via GBIF.org on 2023-09-29.

Description

The dataset contains records of Fishes (Pisces) collected in the River Sabor (NE Portugal) in 2012-2020, in the scope of a study aiming to understand the temporal dynamics of fish communities in relation to natural and anthropogenics drivers in a Mediterranean watershed. The study is part of research carried out at the Long Term Ecological Research Site (LTER) of Baixo Sabor (lter_eu_pt_002; https://deims.org/45722713-80e3-4387-a47b-82c97a6ef62b). The dataset includes data on fish communities obtained through electro-fishing (with restitution) at 74 sampling sites in 2012, and subsequently at 37 of these sites from 2013-2020. Until 2020, the data include a total of 27,514 records of 14 freshwater fish species. Part of these data has already been analised and published (see Ferreira et al., 2016; Mota-Ferreira et al., 2021). The dataset will be regularly updated with additional data from future sampling years.

Purpose

This dataset is part of research carried out at the LTER BAIXO Sabor site, and that will progressively be made available through GBIF and the information management system of iLTER (https://deims.org/).

Sampling Description

Study Extent

Data were collected in 50-m sampling reaches distributed across the entire watershed of the Sabor River and its main tributaries (e.g., Maçãs, Angueira), and they are located in the municipalities of Torre de Moncorvo, Alfândega da Fé, Mogadouro, Macedo de Cavaleiros, Bragança and Vimioso.

Sampling

The data was collected between 2012 and 2020, using standard electrofishing protocols (INAG, 2008) in a stream stretch of 50 meters for 15-25 minutes, with longer surveys in wider and deeper streams to properly cover the stretch. Within each segment, fish were sampled using a single anode electrofishing gear (350-750V, 3-5A, DC). Electrofishing was always conducted by the same operator, while a second operator was tasked with the netting of the displaced fish. All captured individuals were identified on site and released after the sampling session. In accordance with the Portuguese legislation, all individuals belonging to exotic species were euthanized, instead of being returned to the wild. All sampling were conducted under the appropriate permits of Portuguese conservation authority, the Instituto da Conservação da Natures e Florestas (ICNF). Details of the methods are available in Ferreira et al. (2016) and Mota-Ferreira et al. (2021).

Quality Control

All fish identifications were performed by experienced researchers and technicians
