This data is from two surveys conducted to monitor development of small hydropower development projects and assess fish biodiversity as part of Environmental Impact Assessment to establish a conservation area. The monitoring for a hydropower development project was on River Kagera where a small hydropower dam is under development. The second survey was in Kiyanja/Kyazanga wetland in Lwengo district within the Lake Victoria basin.

Data Records

The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 87 records.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Project Data

This dataset was part of a project to advance access to quality freshwater data and information in Uganda by harnessing capacity in data mobilization, data available through GBIF and engagements with data user institutions. The goal was to advance utility of the data in conservation decision making, advocacy, education and reporting on biodiversity. Limited capacity of users to develop biodiversity information from primary biodiversity data, coupled with some deficiencies in data available through GBIF, is a main barrier to data use. This project worked to improve the quality of the data the National Fisheries Resources Research Institute (NaFIRRI) published through GBIF and used all the data available to develop freshwater biodiversity information to guide conservation planning. The quality of the occurrences were improved by linking them with abundance data and coordinates. Then, using all data available in GBIF, the project developed information products tailored to conservation planning. The information was envisaged to have a direct entry point into policies and practices of Uganda’s agricultural sector. The sector had been identified by the National Environmental Management Authority (NEMA) through a national biodiversity information Political and Economic Analysis (PEA), as the biggest sector threatening biodiversity. The information products developed were tailored to the information needs of the sector as defined in the PEA.

Title Advancing freshwater biodiversity data and information access, utility and relevance for conservation decision making in Uganda
Identifier BID-AF2020-145-USE
Funding The project was funded by European Union through the Biodiversity Information for Development (BID) programme of the Global Biodiversity Information Facility (GBIF). Co-funding was available from the JRS Biodiversity Foundation, Royal Belgian Institute of Natural Sciences, and Government of Uganda
Study Area Description The project was a national project, mobilizing data from all water bodies in Uganda
Design Description NaFIRRI implemented biodiversity informatics projects in the past but freshwater biodiversity data remained in less useful formats especially for aquatic invertebrates and algae. Data mobilization in this project involved identifying and digitizing all available data from existing soft and hard copy records. Taxa occurrences and associated abundance data where applicable, were mobilized and published through GBIF. The goal was to fill the data gaps.

Sampling Methods

On river Kagera, sampling locations were selected from zones of direct influence of the development hydropower plant. In addition, areas further upstream and downstream away from the development were also sampled. Fish sampling was done using a multi gear approach. Traps, gillnets (1-2.5 inches) and an electrofisher were used. Fishermens' catches from Known localities were also useful in gathering fish observations. Experimental gillnets of mesh sizes of 1-2.5 inches were used in the river at intervals of at least two hours. Electrofishing was conducted at selected habitats. This was conducted using a SUM electrofisher equipped with a battery and a 2 m long floating copper cathode. Minnow traps were set in littoral areas along the riverbanks. In the wetland, only electrofishing was conducted at the selected sites following guidance. Upon retrieval, all the catch was identified to species level according to Greenwood (1966). The fish species were counted and weighed.

Study Extent The datasets cover River Kagera section and Kiyanja/Kyazanga wetland in the Lake Victoria basin. The assessments were conducted in March to April 2020 and August 2020 respectively.
Quality Control Appropriate fish identification guides were used.

Method step description:

  1. Taxonomic identification of the fish was made according to Greenwood (1966).
