The contribution of citizen scientists to environmental monitoring is notably increasing significantly. Governments worldwide establish Water Users Associations (WUAs) as a good practice model to implement Integrated Water Resource Management (IWRM) at local levels. These associations target different stakeholders depending on the expected outcome....
Increasing unsustainable agricultural and land management activities reduce the effectiveness of wetlands in absorbing heavy metals. This leads to high and detectable heavy metal levels in wetland soil and fish, respectively. This study assessed the content of heavy metals, particularly cadmium (Cd), chromium (Cr), cobalt (Co), lead (Pb), and nicke...
The genus Polynucleobacter (family Burkholderiaceae) is phylogenetically subdivided into at least four subclusters. One of those, subcluster PnecC, was recognized as a cryptic species complex. Here we test by comparative genome analyses whether subcluster PnecD, currently solely represented by the species Polynucleobactercosmopolitanus, also repres...
Small-scale fisheries in developing countries are characterized by uncertain futures attributable to ever-increasing pressures on wetland resources. Data on the interconnectivity between wetland fishery, land-use changes and the socio-economic situation in the Mpologoma wetland, Uganda, were obtained through interviews and structured questionnaire...
The Mpologoma River wetland is highly negatively impacted by rice growing and yet it provides habitat to endemic Clarias species that are important to the wetland fishery. Variations in life-history biometrics of small Clarias species at various wetland sites in relation to land-use changes within the wetland were studied in 2012. Four sites expose...
To determine the possible success or failure of the propagation system, plankton species diversity and biomass were investigated for 98 days in relation to fish fingerling numbers produced from the fish refugia along rice paddies. The experiment was laid out in a split-plot design, with a rice variety (Kairo 25) as the main plot and method of
rice-...
The declining Lake Victoria fisheries resource led to a growing recognition of aquaculture as a source
of livelihood to riparian communities. Finger ponds speculated to naturally stock fish during flooding
and retain them during dry seasons were introduced within the lake’s wetlands. In order to develop a
better understanding of these ponds’ dynami...

An experiment was conducted for 98 days in the Lake Victoria Basin to investigate the interactions of fish and rice growth performance in rice paddies. The experiment was laid out in a split-plot design, with rice cultivar as the main plot and method of rice-fish culture as the sub-plot. Treatments consisted of two levels of rice-fish culture and t...

Research has been on the impact of point source pollution on aquatic systems using water quality analysis and land use changes. Which other ways can scientifically point the effect of flower farms on aquatic ecosystems such as wetlands and streams?
SWAT model was set for nutrients analysis. We are at the point of calibrating the nutrient outputs using the observed data. The model NO3 and total phosphorus are given in kg/ha while our field observations of river nutrients N03 and total phosphorus are in mg/l. We have failed to reach a resolution on standardising the all values in the same units.
I have searched for this type of referencing format but failed to get any idea of what it could be like.
I have tried running the analysis but formatting the figures into want I want give me errors.
If one has enough climate and water data in a system over the years, swat can predict the major water quality parameters for those years. How can one use that data to predict the trend of fish?
There are so many upcoming journals which may not be suitable for advancing my career if i publish with them.
Imagine one has mean fish yield for part of the wetland in kg/km2/yr, how would you extrapolate that to kg/ha/yr?
I am different catfish species catch to water quality. Some species catch is negatively affected by poor water quality while others no significant differences are recorded. Could it that for the later their resilience has not been compromised and what could their point of shift.
