“…Furthermore, due to species-and size-dependent factors, as well as to changes in fish behaviour and catchability, gillnet catches never reflect a true image of the abundance of a fish species or the entire fish community, but are a sample of the catchable assemblage considering the used gillnet (Mustamäki & Mattila, 2015;Olin et al, 2016).…”

Coastal systems experience strong impacts of ongoing environmental change, affecting fish communities and subsequently fishery yields. In the Baltic Sea, the combined effects of climate‐induced changes and eutrophication‐related pressures constitute major threats to its living resources. Although much work has been devoted to uncovering environmental impacts on the commercially most valuable fish stocks, only little is known about community‐wide responses of fished species and how environmental change may affect their yield. In this study, the authors use a joint species distribution modelling framework to disentangle environmental impacts on species‐specific fishery yields of 16 fished species along the coast of Finland over four decades. The authors show that environmental covariates substantially contributed to variations in fishery yields and are likely to have strong impacts on fished resources also in the future. Salinity and near‐bottom oxygen concentration emerged as the strongest environmental drivers of yields at the community level, whereas temperature was particularly important for cod (Gadus morhua) and sprat (Sprattus sprattus) yields. The authors found shore density to be an important predictor for fisheries resources especially for freshwater fish. The results of this study suggest that the changes in environmental conditions during the past four decades had a positive effect on the yields of freshwater and warm‐affinity species, whereas yields of marine cold‐affinity species have been mainly negatively affected by contracting favourable habitats, becoming warmer and less saline.

“…Perca fluviatilis growth could be affected by basin depth and size, because basin morphology affects fish community structure and abiotic factors in the Baltic (Snickars et al, 2005(Snickars et al, , 2009). Productivity differences among locations may also drive some of the community and growth differences (Adjers et al, 2006;Mustamäki & Mattila, 2015;Persson et al, 1992) observed in this study.…”

Growth of Eurasian perch Perca fluviatilis L. and fish community structure between sites within a marine‐protected area (MPA) and unprotected sites in the Baltic Sea were examined. Von Bertalanffy, logistic and Gompertz growth models were fitted to P. fluviatilis length at age data, and the logistic model was the most parsimonious for growth between locations. A larger mean maximum size (L∞) and a smaller instantaneous growth rate (g) were found within the MPA. All three models also predicted that after age seven, fish inside the MPA would be larger. Community structure differed with more P. fluviatilis collected outside of the MPA, and more roach Rutilus rutilus (L.) and bleak Alburnus alburnus (L.) collected inside the MPA. These growth differences may be indicative of recreational fishing effects on P. fluviatilis outside of the MPA, a result of complex interspecific and intraspecific species interactions, or other undetected environmental variation between locations.

P. robustoides tāpat kā arī citu Ponto-Kaspijas sānpelžu klātbūtnē tiek novērotas ūdens ekosistēmu strukturālās un funkcionālās izmaiņas (Arbačiauskas, Gumuliauskaitė, 2007;Berezina et al, 2011;Berezina et al, 2016 (Olsson et al, 2012;Mustamäki et al, 2015). Tomēr, ņemot vērā piekrastes sugu lokālo raksturu, to izmaiņas raksturo vispārīgās vides izmaiņu tendences dotajā rajonā (Laikre et al, 2005).…”
