The concept of fecundity regulation in plaice (Pleuronectes platessa) tested on three Irish Sea spawning populations
Kennedy, James; Witthames, Peter R.; Nash, Richard D.M. (Journal article; Peer reviewed, 2007)The fecundity of European plaice (Pleuronectes platessa) in the Irish Sea between 2000 and 2004 was estimated during the spawning season for fish in the three main spawning areas (Liverpool Bay, the Cumbrian coast, and the ... -
Environmental stressors may cause unpredicted, notably lagged life-history responses in adults of the planktivorous Atlantic herring
dos Santos Schmidt, Thassya Christina; Devine, Jennifer Ann; Slotte, Aril; Claireaux, Marion; Johannessen, A; Enberg, Katja; Oskarsson, Gudmundur; Kennedy, James; Kurita, Yutaka; Kjesbu, Olav Sigurd (Peer reviewed; Journal article, 2020)Here we challenge traditional views on the direction of change in teleost body condition and reproductive traits in response to abiotic and biotic factors by studying the data-rich, planktivorous Norwegian spring-spawning ... -
Global, regional, and cryptic population structure in a high gene-flow transatlantic fish
Jansson, Eeva; Faust, Ellika; Bekkevold, Dorte; Quintela, Maria; Durif, Caroline; Halvorsen, Kim Aleksander Tallaksen; Dahle, Geir; Pampoulie, Christophe; Kennedy, James; Whittaker, Benjamin; Unneland, Laila; Post, Søren; André, Carl; Glover, Kevin Alan (Peer reviewed; Journal article, 2023)Lumpfish (Cyclopterus lumpus) is a transatlantic marine fish displaying large population sizes and a high potential for dispersal and gene-flow. These features are expected to result in weak population structure. Here, we ... -
Liver energy, atresia and oocyte stage influence fecundity regulation in Northeast Arctic cod
Skjæraasen, Jon Egil; Nash, Richard D.M.; Kennedy, James; Thorsen, Anders; Nilsen, Trygve; Kjesbu, Olav Sigurd (Journal article; Peer reviewed, 2010-04-08)Marine ecosystems are changing; global warming-induced increases in water temperatures and fishing have caused truncated age structures and small sizes at maturity in many stocks. This may affect both populations’ total ... -
Mechanisms regulating oocyte recruitment and skippedspawning in Northeast Arctic cod (Gadus morhua L.)
Skjæraasen, Jon Egil; Kennedy, James; Thorsen, Anders; Fonn, Merete; Strand, Bente; Mayer, Ian; Kjesbu, Olav Sigurd (Journal article; Peer reviewed, 2009-09)To examine mechanisms that affect fecundity, atresia and skipped spawning in Northeast Arctic cod (Gadus morhua L.), we conducted an experiment where wild-caught cod (>60 cm) kept under restricted food regimes were subjected ... -
