Forskningsöversikt (refereegranskat)abstract
- Abborre och tånglake längs kusten har länge visat tecken på att de inte mår bra. Inte ens i områden som förutsätts vara mer eller mindre opåverkade av miljögifter, som exempelvis Kvädöfjärden i Östergötland. Här samarbetar nu flera forskare i ett nytt stort projekt för att försöka ta reda på om det är just miljögifter som är orsaken till den dåliga fiskhälsan. I så fall vilka och var kommer de ifrån? Det är en stor uppgift med många utmaningar och jakten på orsaker har bara börjat.

Health status in fish in eight polluted coastal sites in Sweden.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The health of perch and eelpout were assessed by effect-based methods (including physiological and biochemical endpoints, i.e. biomarkers) in eight different polluted hot spot areas along the Swedish coast. An important purpose was to get an overview of the severity of impacts of environmental pollutants in the polluted areas compared to the reference sites. Taken together, the results suggest moderate to severe impacts on the fish health in all hot spot areas studied. The results indicate that coastal areas act as sources of environmentally harmful substances to the aquatic environment. In addition, the results contributes to the assessment of biological effects of contaminants, which is an important component within EUs Marine Strategy Framework Directive.

Tidskriftsartikel (refereegranskat)abstract
- Perch (Perca fluviatilis) has been used in biological effect monitoring in a program for integrated coastal fish monitoring at the reference site Kvadofjarden along the Swedish east coast, which is a site characterized by no or minor local anthropogenic influences. Using a set of physiological and biochemical endpoints (i.e., biomarkers), clear time trends for "early warning" signs of impaired health were noted in the perch from this site, possibly as a result of increased baseline pollution. The data sets also showed relatively large variations among years. To identify additional temporal variation in biological parameters, global mRNA expression studies using RNA sequencing was performed. Perch collected in 2010 and 2014 were selected, as they showed variations in several biomarkers, such as the activity of the detoxification enzyme CYP1A (EROD), the plasma levels of vitellogenin, markers for oxidative stress, white blood cells count and gonad sizes. The RNA sequencing study identified approximately 4800 genes with a significantly difference in mRNA expression levels. A gene ontology enrichment analysis showed that these differentially expressed genes were involved in biological processes such as complement activation, iron ion homeostasis and cholesterol biosynthetic process. In addition, differences in immune system parameters and responses to the exposure of toxic substances have now been verified in two different biological levels (mRNA and protein) in perch collected in 2010 and 2014. Markedly higher mRNA expression of the membrane transporter (MATE) and the detoxification enzyme COMT, together with higher concentrations of bioactive naturally produced brominated compounds, such as brominated indoles and carbazoles, seem to indicate that the perch collected in 2014 had been exposed to macro- and microalga blooming to a higher degree than did perch from 2010. These results and the differential mRNA expression between the 2 years in genes related to immune and oxidative stress parameters suggest that attention must be given to algae blooming when elucidating the well-being of the perch at Kvadofjarden and other Baltic coastal sites.

Tånglake och abborre varnar för miljöförändringar

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Hälsotillståndet hos tånglake och abborre har undersökts sedan slutet av 1980-talet. Tånglakens hälsostatus bedöms nu vara god i referensområden på väst- och ostkusten - men tånglake som lever nära stora städer visar tydliga tecken på att vara påverkad av miljöföroreningar.
