Abstract In recent years, the issue of spawner harvesting has been frequently addressed by different groups stakeholders involved in exploitation fish resources. The increasingly numerous angling circles, which use these resources recreationally, question current rules stocking management Poland, and its legal economic status become focus scientists’ interest. aim study was to present discuss results a questionnaire survey managers owners lake fisheries entities order identify determinants related harvesting. Questionnaires were collected from total 76 entities, concerned 1921 lakes with area 174,078 ha, accounts for more than 64% used fishing purposes Poland. paper presents inter alia occupational characteristics respondents; their positions on effect ecosystem, environmental protection, social factors; anglers’ assessments harvesting; actual potential methods regulating this negative positive effects introduction prohibition show that respondents under generally do not see need additional (except those already place) regulations concerning harvesting, most them notice adverse introduction, but they are also aware possible changes impact management.

Abstract Cyanobacterial blooms have substantial direct and indirect negative impacts on freshwater ecosystems including releasing toxins, blocking light needed by other organisms, depleting oxygen. There is growing concern over the potential for climate change to promote cyanobacterial blooms, as positive effects of increasing lake surface temperature growth are well documented in literature; however, there evidence that also being initiated persisting relatively cold‐water temperatures (< 15°C), ice‐covered conditions. In this work, we provide review abiotic drivers physiological adaptations leading these offer a typology lesser‐studied discuss their occurrence under changing

Abstract An important group of protozooplankton, the ciliates, are a crucial component aquatic food webs. They main grazers on bacteria and algae transferring carbon to higher levels web (metazooplankton fish fry). Changes in quality quantity protozooplankton can modify metazooplankton, especially predatory copepods, causing changes energy transfer matter cycle. Observable climate change is one most significant factors promoting increase cyanobacterial blooms. Therefore, aim this study was find out how blooms relationships between ciliates (prey) copepods (predator), discover possible pathways freshwater We analysed relationship biomass feeding guilds (algivorous, bacterivorous, bacteri-algivorous). The predators with algivorous bacteri-algivorous ciliate biomasses, simultaneous lack bacterivorous biomass, demonstrates that bacterial fixed may be only partially contributing total passed through link. Results demonstrated bloom enhanced prey predator. Larger free-swimming species appear play greater role than smaller sedentary species.

A seasonal plethora of cyanobacteria in the plankton community can have severe implications, not only for water ecosystems but also availability treated water. The catchment Obrzyca River (a source drinking water) is seasonally exposed to harmful cyanobacterial bloom. Previous studies (2008–2012; 2019) revealed that most polluted was Uście, close outlet Rudno Lake (at sampling point). Therefore, effect on this lake specifically examined study.
