Investigating the drivers of maturation dynamics in Barents Sea haddock (Melanogrammus aeglefinus)
(Journal article; Peer reviewed, 2011-08)Changes in size and age at maturation of many exploited fish stocks have been investigated and the influences of environmental factors and exploitation have often been inferred, but not explicitly investigated. Here we ... -

Investigating the frequency of triploid Atlantic salmon in wild Norwegian and Russian populations
(Journal article; Peer reviewed, 2018)Fish may display variations in ploidy, including three sets of chromosomes, known as triploidy. A recent study revealed a frequency of ~ 2% spontaneous (i.e., non-intentional) triploidy in domesticated Atlantic salmon ... -
Investigating the genetic structure of the parasites Anisakis pegreffii and A. berlandi (Nematoda: Anisakidae) in a sympatric area of the southern Pacific Ocean waters using a multilocus genotyping approach: first evidence of their interspecific hybridization
(Peer reviewed; Journal article, 2021)The southern Pacific Ocean, off the New Zealand coast, has been reported as one sympatric area of the two parasite species Anisakis pegreffii and A. berlandi. Here, a multilocus genotyping approach, based on a panel of ... -
Investigation into the fate of C-14-labelled xenobiotics(naphthalene, phenanthrene, 2,4,5,2 ',4',5 '-hexachlorobiphenyl, octachlorostyrene) in Bermudian corals
(Journal article; Peer reviewed, 1983-02-28)Uptake and elimination of 4 labelled lipid-soluble xenobiotics (naphthalene, phenanthrene, 2,4,5,2',4',5'-hexachlorobiphen(yPlC B), octachlorostyrene) were studied in 19 anthozoans and 1 hydrozoan common to Bermudian ... -
