Assessing the performance of statistical classifiers to discriminate fish stocks using Fourier analysis of otolith shape
Smolinski, Szymon; Schade, Franziska M.; Berg, Florian (Peer reviewed; Journal article, 2019)The assignment of individual fish to its stock of origin is important for reliable stock assessment and fisheries management. Otolith shape is commonly used as the marker of distinct stocks in discrimination studies. Our ... -
Automatic interpretation of salmon scales using deep learning
Vabø, Rune; Moen, Endre; Smolinski, Szymon; Husebø, Åse; Handegard, Nils Olav; Malde, Ketil (Peer reviewed; Journal article, 2021)For several fish species, age and other important biological information is manually inferred from visual scrutinization of scales, and reliable automatic methods are not widely available. Here, we apply Convolutional ... -
Cascading effects of temperature alterations on trophic ecology of European grayling (Thymallus thymallus)
Smolinski, Szymon; Glazaczow, Adam (Journal article; Peer reviewed, 2019)The aims of this project were to study: diet composition, food selectivity and the phenology of different prey items in grayling’s (Thymallus thymallus) diet. It was hypothesized, that alterations in mayfly emergence, ... -
A century of fish growth in relation to climate change, population dynamics and exploitation
Denechaud, Come; Smolinski, Szymon; Geffen, Audrey J.; Godiksen, Jane Aanestad; Campana, Steven E. (Peer reviewed; Journal article, 2020)Marine ecosystems, particularly in high‐latitude regions such as the Arctic, have been significantly affected by human activities and contributions to climate change. Evaluating how fish populations responded to past changes ... -
Century-long cod otolith biochronology reveals individual growth plasticity in response to temperature
Smolinski, Szymon; Deplanque-Lasserre, Julie; Hjörleifsson, Einar; Geffen, Audrey J.; Godiksen, Jane Aanestad; Campana, Steven E. (Peer reviewed; Journal article, 2020)Otolith biochronologies combine growth records from individual fish to produce long-term growth sequences, which can help to disentangle individual from population-level responses to environmental variability. This study ... -
Considerations for management strategy evaluation for small pelagic fishes
Siple, Margaret; Koehn, Laura; Johnson, Kelli F; Punt, André E.; Canales, T. Mariella; Carpi, Piera; de Moor, Carryn L.; De Oliveira, José A.A.; Gao, Jin; Jacobsen, Nis S.; Lam, Mimi Elizabeth; Licandeo, Roberto; Lindgren, Martin; Ma, Shuyang; Óskarsson, Gudmundur Jóhann; Sanchez-Maroño, Sonia; Smolinski, Szymon; Surma, Szymon; Tian, Yongjun; Tommasi, Desiree; Gutierrez T., Mariano; Trenkel, Verena; Zador, Stephani; Zimmermann, Fabian (Peer reviewed; Journal article, 2021)Management strategy evaluation (MSE) is the state-of-the-art approach for testing and comparing management strategies in a way that accounts for multiple sources of uncertainty (e.g. monitoring, estimation, and implementation). ... -
Contrasting patterns in the occurrence and biomass centers of gravity among fish and macroinvertebrates in a continental shelf ecosystem
Friedland, Kevin D.; Smolinski, Szymon; Tanaka, Kisei (Peer reviewed; Journal article, 2021)The distribution of a group of fish and macroinvertebrates (n = 52) resident in the US Northeast Shelf large marine ecosystem were characterized with species distribution models (SDM), which in turn were used to estimate ... -
Counting stars: contribution of early career scientists to marine and fisheries sciences
Smolinski, Szymon; Ottmann, Daniel; Outinen, Okko; Schadeberg, Amanda; Melli, Valentina; Funk, Lara; Denechaud, Côme; Wieczorek, Alina; Orio, Alessandro; Mussgnug, Robert; Morkune, Rasa; Vereide, Emilie Hernes; Zdulska, Maja; Genevieve, Philips; Lishchenko, Fedor; Srebaliene, Greta (Peer reviewed; Journal article, 2022)Scientific careers and publishing have radically changed in recent decades creating an increasingly competitive environment for early career scientists (ECS). The lack of quantitative data available on ECS in marine and ... -
Differences in metabolic rate between two Atlantic cod (Gadus morhua) populations estimated with carbon isotopic composition in otoliths
Smolinski, Szymon; Denechaud, Come; von Leesen, Gotje; Geffen, Audrey J.; Grønkjær, Peter; Godiksen, Jane A.; Campana, Steven E. (Peer reviewed; Journal article, 2021)The isotopic composition of inorganic carbon in otoliths (δ13Coto) can be a useful tracer of metabolic rates and a method to study ecophysiology in wild fish. We evaluated environmental and physiological sources of δ13Coto ... -
Growth portfolios buffer climate-linked environmental change in marine systems
Campana, Steven E.; Smolinski, Szymon; Black, Bryan A.; Morrongiello, John R.; Alexandroff, Stella J.; Andersson, Carin; Bogstad, Bjarte; Butler, Paul G.; Denechaud, Côme; Frank, David C.; Geffen, Audrey J.; Godiksen, Jane Aanestad; Grønkjær, Peter; Hjörleifsson, Einar; Jónsdóttir, Ingibjörg G.; Meekan, Mark; Mette, Madelyn; Tanner, Susanne E.; van der Sleen, Peter; von Leesen, Gotje (Peer reviewed; Journal article, 2022)Large-scale, climate-induced synchrony in the productivity of fish populations is becoming more pronounced in the world's oceans. As synchrony increases, a population's “portfolio” of responses can be diminished, in turn ... -
