Birth-date selection in early life stages of plaice Pleuronectes platessa in the eastern Irish Sea (British Isles)
Fox, Clive J.; Geffen, Audrey J.; Taylor, Natasha; Davison, Phil; Rossetti, Helen; Nash, Richard D.M. (Journal article; Peer reviewed, 2007-09-13)For species with extended spawning seasons, short periods of beneficial conditions often lead to disproportionate survival of sub-sets of the offspring. This has been demonstrated for freshwater fish and for marine pelagic ... -

External peer review of survey serier: Lessons From the Rügen Herring Larvae Survey
Zimmermann, Christopher; Dickey-Collas, Mark; Nash, Richard D.M.; Hammer, Cornelius (ICES CM documents;2007/P:10, Working paper, 2007)ICES coordinated surveys are, on a non-regular basis, reviewed by parent expert groups. A potential problem is that these are often conducted by evaluators being themselves involved in the surveys, thus lacking ... -

Thorsen, Anders; Witthames, Peter R.; Marteinsdottir, Gudrun; Nash, Richard D.M.; Kjesbu, Olav Sigurd (Journal article; Peer reviewed, 2010-05)Some fish species have wide distribution areas that span very different habitats. In this investigation we have studied Atlantic cod (Gadus morhua), which is an example of such a species, to demonstrate how this may have ... -

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 ... -
Long-term changes in the total egg production of Norwegian spring-spawning herring Clupea harengus (L.)—Implications of variations in population structure and condition factor
