“…Other species are commercially important for local fisheries, such as the Nile tilapia ( Oreochromis niloticus ), which accounted for 65% of the total annual catch ( Degsera et al, 2021 ). Lake Tana is also home to over 200 species of birds ( Worku, 2014 ), and mammals, like the African clawless otter ( Ergete et al, 2018 ). The species in Lake Tana are part of a complex food web, consisting of species that feed on aquatic vegetation (e.g., Labeobarbus surkis ), carnivorous species (e.g., L. crassibarbis ), while top predators (e.g., marine birds and mammals) feed on various fish species ( Mengistu et al, 2017 ).…”

Personal protective equipment (PPE) pollution has become one of the most pending environmental challenges resulting from the pandemic. While various studies investigated PPE pollution in the marine environment, freshwater bodies have been largely overlooked. In the present study, PPE monitoring was carried out in the vicinity of Lake Tana, the largest lake in Ethiopia. PPE density, types, and chemical composition (FTIR spectroscopy) were reported. A total of 221 PPEs were identified with a density ranging from 1.22 × 10 −5 PPE m −2 (control site S1) to 2.88× 10 −4 PPE m −2 with a mean density of 1.54 × 10 −4 ± 2.58 × 10 −5 PPE m −2 . Mismanaged PPE waste was found in all the sampling sites, mostly consisting of surgical face masks (93.7%). Statistical analyzes revealed significantly higher PPE densities in sites where several recreational, touristic, and commercial activities take place, thus, revealing the main sources of PPE pollution. Furthermore, polypropylene and polyester fabrics were identified as the main components of surgical and reusable cloth masks, respectively. Given the hazard that PPEs represent to aquatic biota (e.g., entanglement, ingestion) and their ability to release microplastics (MPs), it is necessary to implement sufficient solid waste management plans and infrastructure where lake activities take place. Additionally, local authorities must promote and ensure sustainable tourism in order to maintain the ecosystems in Lake Tana. Prospective research priorities regarding the colonization and degradation of PPE, as well as the release of toxic chemicals, were identified and discussed.

“…

Aquaculture and fishing industries have a long history of humanwildlife conflict, with piscivorous species considered either an active threat or at least a nuisance with regard to fish stocks (Burr et al, 2020;Cook et al, 2022;Cummings et al, 2019). While conflict between inland fishing interests (commercial, subsistence and recreational) and predators such as spotted-necked otters (Hydrictis maculicollis) (Akpona et al, 2015), African clawless otters (Aonyx capensis) (Butler, 1994;Ergete et al, 2018) and white-breasted cormorants (Phalacrocorax carbo lucidus) (Linn & Campbell, 1992) are known to occur in parts of Africa, little is known about the extent and effects of such conflicts as compared to many other parts of the world.

Human–wildlife conflict in African aquaculture and fisheries is poorly understood. We investigated this conflict through a questionnaire aimed at owners and managers of fly‐fishing properties in South Africa. While perceptions of losses varied, all respondents reported losses to predators. Resulting mitigation measures, including lethal control, were employed mostly against cormorants (Phalacrocorax spp.) and otters (Aonyx capensis and Hydrictis maculicollis). Given that fly‐fishing properties potentially provide valuable habitat for protected species such as otters, our results highlight a need for improved mitigation measures and exploring alternative options of potentially generating income from tourism associated with the presence of charismatic predators.
