Données sur le projet

Our dataset is mobilized from multiple assessments conducted to monitor conservation projects and assess fish biodiversity as part of Environmental Impact Assessments for hydropower and oil development projects in Uganda. Monitoring was for a conservation project on Lake Victoria. The assessment for hydropower development was on River Kyambura where a small hydropower dam is proposed or under development. The assessments for oil development projects were on Lake Albert or associated rivers in proximity with nearby oil exploration areas, Karuma-Olwiyo transmission lines and water courses traversed by the East African Crude Oil Pipeline (EACOP).

Titre Fish Biodiversity Assessments for Conservation, Hydropower and Oil development projects
Financement Conservation monitoring assessments were funded by Flora and Fauna International. Environmental Impact Assessments were funded by the agencies responsible for the development projects.
Description du domaine d'étude / de recherche The monitoring covered parts of Lake Victoria. The assessment for hydropower development was on River Kyambura, Western Uganda where a small dam is proposed for hydropower generation. River Kyambura flows to Kazinga channel through Queen Elizabeth National park. The assessments for oil development projects were on Lake Albert and rivers such as Waiga, Waisoke, Victoria Nile, Ayago and Waki. All water bodies in the dataset are lakes Albert and Victoria and rivers Ayago, Kafu, Kagera, Katonga, Kibale, Kyambura, Murchison falls national park, Nabakazi, Sonso, Tangi, Waiga, Waisoke, Waki, Wambabya and Victoria Nile.
Description du design Sampling locations were selected from the areas of influence for the conservation and development projects. Fish sampling was done using a multi gear approach which involved experimental gillnets mesh (1-2.5 inches in rivers set for two hours and 1-8 inches in lakes set overnight), fyke nets, basket and minnow traps, and hook and line rods and a portable electro- fisher. Additional data in a few instances, were obtained from local fishermen on site. Where applicable, efforts were made to include a diversity of habitats in the sampling such as littoral zones, river mouths, deltas and open water.

Méthodes d'échantillonnage

Sampling description Experimental gillnets of mesh sizes of 1-2.5 inches were used in rivers and were left to fish passively for a period of at least 2hrs. After the two hours, gillnets were retrieved. The fish were counted and weighed. In lakes, gillnets of 1-8 inches, set overnight were used. Ectrofishing, a non –lethal fishing methods was conducted at the site-specific selected habitats. This was conducted using a SUM electrofisher equipped with battery and a 2 m long floating copper cathode. Fyke nets, basket and minnow traps were set in littoral areas of lakes and along the banks of rivers. Upon retrieval, all the catch was identified to species level according to Greenwood (1966). The fish species were counted and weighed.

Etendue de l'étude The datasets covers lakes Albert and Victoria and rivers Ayago, Kafu, Kagera, Katonga, Kibale, Kyambura, Murchison falls national park, Nabakazi, Sonso, Tangi, Waiga, Waisoke, Waki, Wambabya and Victoria Nile. The monitoring for the conservation area on Lake Victoria was conducted in 2017 and 2018. Lake Victoria. The assessment for hydropower development on River Kyambura was done twice in 2018 and 2019. Most of the other water bodies were sampled once, typical for environmental impact assessments.

Fyke nets, basket and minnow traps were set in littoral areas of lakes and along the banks of rivers. Upon retrieval, all the catch was identified to species level according to Greenwood (1966). The fish species were counted and weighed.
  2. Identification in the field Taxonomic identification of the fish was made using according to Greenwood (1966).
