“…The SGR was an important index to measure the economic benefits of fisheries, and the larger the value was, the greater of fish would be. Malinich et al ( 2018 ) found that MPs had no impact on the growth of the fathead minnow Pimephales promelas , and a similar result was detected from the brown trout Salmo trutta (Jakubowska et al, 2020 ). However, MPs could induce growth inhibition in the common carp Cyprinus carpio .…”

Compared with marine organisms, research on microplastics (MPs) in freshwater organisms is still less although MPs have been widely found in the freshwater ecosystem. Hypoxia is a ubiquitous issue in freshwater aquaculture, and under such scenarios, the toxic effects of MPs on typical aquaculture fish need to be clarified. In this study, we studied the effects of MPs (polystyrene) on specific growth rate (SGR), hypoxia-inducible factor-1α (HIF-1α), tumor necrosis factor-α (TNF-α), interleukin-8 (IL-8), and interferon (IFN) in the yellow catfish (Pelteobagrus fulvidraco) under hypoxic conditions. After 15 days of exposure, the SGR was not affected by MPs or hypoxia. MPs significantly increased the expressions of HIF-1α and TNF-α but inhibited the expression of IFN at high concentration MPs under normoxia. However, hypoxia significantly inhibited the expression of IL-8 and TNF-α under high MP concentration and low MP concentration, respectively. In addition, MPs had significant concentration-dependent inhibitory effects on IFN under hypoxia. Surprisingly, a positive correction between HIF-1α and TNF-α was found in fish. Although hypoxia might alleviate the effects of MPs with low concentrations, the interaction of hypoxia and MPs aggravated the negative effects of MPs on immune factors at high concentration MPs. This study provided new insight into the complex effects of hypoxia and MPs on aquatic organisms, and future studies should focus on the cellular pathways of immune cells in fish. Given that MPs could induce the immune response in fish, considerations should be paid to the impacts of MPs on freshwater aquaculture, and hypoxia should be taken into consideration when evaluating the effects of MPs.

“…Generally, the polymers detected most frequently are the ones produced in highest quantities, such as polyethylene and polypropylene. The beaches of the Baltic Sea are significantly polluted with plastic particles, with reported numbers ranging between less than 10 to over 1000 plastic particles per kg dry weight (Urban-Malinga et al, 2020). An extensive survey of 190 sandy beaches across the whole Baltic Sea area yielded 4921 plastic particles >2mm, mostly industrial 2220 pellets (19.8 %), non-identifiable plastic pieces 2-25 mm (17.3 %), and cigarette butts (15.3 %) (Haseler et al, 2020).…”

“…Long-term microplastics exposure on early life stages of sea trout showed no effects on hatching rate, larvae survival, or growth. Still, it generated nuclear abnormalities and chromosomal damage, indicating potential genotoxic effects (Jakubowska et al, 2020). Further data on ecotoxicological effects of microplastics on Baltic Sea biota are still rare.…”

Abstract. Coastal environments, in particular heavily populated semi-enclosed marginal seas and coasts like the Baltic Sea region, are stongly affected by human activities. A multitude of human impacts, including climate change, affects the different compartments of the environment, and these effects interact with each other. As part of the Baltic Earth Assessment Reports (BEAR), we present an inventory and discussion of different human-induced factors and processes affecting the environment of the Baltic Sea region, and their interrelations. Some are naturally occurring and modified by human activities (i.e. climate change, coastal processes, hypoxia, acidification, submarine groundwater discharges, marine ecosystems, non-indigenous species, land use and land cover), some are completely human-induced (i.e. agriculture, aquaculture, fisheries, river regulations, offshore wind farms, shipping, chemical contamination, dumped warfare agents, marine litter and microplastics, tourism, coastal management), and they are all interrelated to different degrees. We present a general description and analysis of the state of knowledge on these interrelations. Our main insight is that climate change has an overarching, integrating impact on all of the other factors and can be interpreted as a background effect, which has different implications for the other factors. Impacts on the environment and the human sphere can be roughly allocated to anthropogenic drivers such as food production, energy production, transport, industry and economy. We conclude that a sound management and regulation of human activities must be implemented in order to use and keep the environments and ecosystems of the Baltic Sea region sustainably in a good shape. This must balance the human needs, which exert tremendous pressures on the systems, as humans are the overwhelming driving force for almost all changes we see. The findings from this inventory of available information and analysis of the different factors and their interactions in the Baltic Sea region can largely be transferred to other comparable marginal and coastal seas in the world.

Occurring in marine invertebrates haemic (leukemia-like) neoplasia, a disease of potentially infectious nature, arises from genome instabilities leading to multilevel malfunctions and unregulated cell division of presumably haemocyte precursors. As its biochemical characterisation remains unknown, we here present results describing selected physiological and biochemical aspects of the disease measured in neoplastic and healthy clams Limecola balthica. Activities of adenosine deaminase (ADA), alkaline phosphatase (ALP) and FAA levels were measured in haemolymph but no differences in ADA and ALP activities between healthy and neoplastic clams were found. In both clam groups nine FAAs were detected with Asp, Glu, Pro, Ser constituting over 90% of total FAA content. Significantly higher Gln level was detected in leukemic-like clams suggesting an essential role of this FAA in cancer energy production. In neoplastic cells, an impairment of mitochondrial metabolism was observed as a decrease in mitochondrial oxygen consumption and lower cytochrome c oxidase activity. Neoplastic clams were also characterised by significantly higher concentration of ROS, but no elevated response of the oxidative stress markers were found suggesting an efficient antioxidant response. Finally, we, for the first time, report high levels of corticosterone and lower amounts of dehydrocorticosterone, cortisol and cortisone in healthy clams with elevated cortisol level found in neoplastic individuals.
