“…Bathymetric surveying of lakes is one of the most time-consuming and mandatory components of landscape and limnological studies. This fact is also confirmed by other scientists' (Giuliani et al 2019;Paul et al 2019;Muhtadi et al 2020;Chormanski et al 2021;Simpson et al 2021;Hamilton et al 2022;Yang et al 2022) studies related to the bathymetric survey of different water bodies in terms of depth, area and natural-geographical location. In August 2020, high-precision echo sounding with the geodetic surveying of the water section was carried out on Lake Bile.…”

The reassessment of the geoecological state of landscape-lake systems (LLS) and their cartographic modelling employing the methodology of landscape limnology has been conducted. The purpose of this study was to characterize the essence of the applied methodology and to evaluate the geoecological state of LLS based on the case study of the Lake Bile basin, Rivne Natural Reserve, Ukraine and to develop cartographic models of the aquatic complex and its catchment as an information basis for the integrated management of water and land resources of LLS and sustainable nature management. The results obtained from the field instrumental research conducted within the Bile Lake basin were used for substantiating the use of laboratory methods and QGIS software, for producing the catchment land use map and assessing the geoecological state of the basin, for developing the bathymetric model of the reservoir and determining hydrological and hydrochemical parameters, for analyzing the lithological composition of the rocks of the exploratory well, elucidation of the genesis of the reservoir, for the first-time production of landscape maps of the natural-aquatic complex and water catchment, and for establishing landscape-metric characteristics of the lake-basin system. The degree of the anthropogenic load on landscape complexes in the 100-meter zone around the lake was assessed. The performed research showed that the conceptual foundations of landscape limnology, as a modern transdisciplinary scientific direction, are an innovative and effective tool for assessing the geoecological state of LLS, and scientifically supporting the integrated management of its water resources and sustainable nature management.

“…However, this is not the case. Recalculating the MSY using recent estimates of TDS (derived from mean conductivity from Stoyneva-Gärtner et al ( 2020) using a function by Rusydi (2018) that correlates TDS and conductivity) and mean depth (Hamilton et al, 2022) generated a value (16,550 t), close to that of Vakily (1989). This finding suggests that TDS may not be a good predictor of fish yield in the lake.…”

Poor and unreliable knowledge of the status of freshwater fisheries limits their inclusion in governance processes, thereby impeding effective management measures. This threatens the livelihoods of people, particularly in developing countries. Improved knowledge is required to draw the attention of policymakers and stimulate effective management measures to accelerate the sustainability of the freshwater fisheries. In line with this requirement, this paper provides the state of knowledge of the aquatic ecosystem and fisheries of the Lake Edward system, East Africa, focusing on lakes Edward, George and the Kazinga channel. The state of knowledge was accomplished by reviewing existing data and information on aspects of primary productivity and water quality, invertebrates, fish fauna, fish life history and ecology, and fisheries. The waterbodies have been monitored since the 1930s, albeit sporadically, providing data on all the above aspects but with substantial temporal gaps. Adequate and updated data and information exist on the water quality status of the water bodies, extant aquatic taxa (including fishes) and fish catches but with uncertainties in the latter. Data and information gaps exist on the abundance of biotic communities, fish life history, quantitative trophic ecology and fisheries management reference points. The aggregated data and information can directly support decisions for fisheries management. We recommend regular monitoring to fill the data and information gaps, more comprehensive stock assessments and the development of aquatic ecosystem models.

The cadastral information about the lakes of the nature reserve fund (NRF) should be based on landscape-geographic principles using modern geo-information systems.Within the research, based on the instrumental field research and the use of software packages ArcGIS Desktop and ReefMaster Software, a bathymetric map of Lake Serednie (Nobel National Natural Park, Ukraine) and other spatial models were developed. The main hydrological and morphometric parameters of the lake basin were calculated, a landscape map of the natural aquatic complex was created and its landscape metric analysis was carried out at the level of aquatic tracts and facies. The research revealed changes in the level regime and shoreline of the lake caused by the long dry periods of 2016-2021 and life activity of beavers. The created integrated cadastral landscape model of the lake with limnology parameters should serve as a basis for the recreational nature use, monitoring and geo-ecological certification of the reservoirs of the NRF.
