Fisheries provide an important source of food, employment, income, and recreation for people throughout the world (Allison, 2001). Appreciations of fisheries and aquatic ecosystems have been accompanied by increasing concern about the effects of growing human populations and activity on aquatic life and water quality. (lious, et al., 1996). Out of the many links associated to man`s negative imp...

Background: Evaluation of herbicide pollution in aquatic environments needs the great concern and the most important echo-pollutant effects of herbicides are related to their effects on non target aquatic organisms. Native fish can serve as a proper bio-indicator for evaluation  of pollution on aquatic ecosystems. OBJECTIVES: To find environmentally friendly herbicides, in this study the acute ...

The paper endorses a recently emerged interdisciplinary research subject Hydrodynamics of Aquatic Ecosystems, defined as a study of flow-organism interactions in running waters with particular focus on relevant transport processes and mutual physical impacts occurring at multiple scales from the sub-organism scale to the organism patch mosaic scale (comparable to the flow width). This new resea...

Abstract Microplastic particles (MPs) are ubiquitous across a wide range of aquatic habitats but determining an appropriate level risk management is hindered by poor understanding environmental risk. Here, we introduce framework for ecosystems that identifies four critical thresholds, ranging from low regulatory concern to the highest where pollution control measures could be introduced mitigat...
