Maternal influences on offspring size variation and viability in wild European lobster Homarus gammarus
(Working paper, 2010-02-11)In many marine species, large females tend to produce more robust offspring than small females. However, knowledge on maternal influences in decapod crustaceans is limited. This is unfortunate since many decapod populations ... -
Maternal Iodine Status is Associated with Offspring Language Skills in Infancy and Toddlerhood
(Journal article; Peer reviewed, 2018)Inadequate iodine status affects the synthesis of the thyroid hormones and may impair brain development in fetal life. The aim of this study was to explore the association between maternal iodine status in pregnancy measured ... -
Mating competition between farmed and wild cod Gadus morhua
(Journal article; Peer reviewed, 2010-08-18)Increasing numbers of hatchery-produced fish entering marine environments has caused concern over potential fitness depressions in wild populations, yet no study has addressed the likelihood of hybridisation between farmed ... -

Maturation characteristics in Norwegian spring-spawning herring before, during, and after a major population collapse
(ICES CM documents, Working paper, 2002)The immense Norwegian spring-spawning herring (Clupea harengus) population collapsed to the state of commercial extinction in the late 1960s, probably largely due to overfishing; the stock has fully recovered since the ... -
Maturation in North-East-Arctic Haddock.
(ICES CM documents, Working paper, 1999)Maturation in north-east-arctic haddock was studied in relation to fish age; length, weight and condition factor using data from scientific surveys in 1989-1998. In order to investigate the reliability of the maturity ... -
Maturation in the Barents Sea capelin – Contrasting length- and gonad-based metrics
(Peer reviewed; Journal article, 2021)It is assumed that maturation in the Barents Sea capelin is length-dependent, and that fish of at least 14 cm will potentially spawn. Current assessment and management models for the stock are based on this assumption of ... -
Maturation, spawning and egg drift of Arcto-Norwegian haddock (Melanogrammus aeglefinus)

Maturity changes in Norwegian spring-spawning herring Clupea harengus: compensatory or evolutionary responses?
(Journal article; Peer reviewed, 2004-05-19)The stock of Norwegian spring-spawning herring Clupea harengus collapsed to a state of commercial extinction in the 1960s, probably due to both overexploitation and unfavourable climatic conditions. Since the 1980s, the ... -
Maturity studies of Barents Sea capelin: Variations in length at maturity for female capelin
(PINRO-IMR Symposium, Conference object, 1985)The sexual maturation of female capelin in the Barents Sea is studied using a new method based on microscope investigation of eggs. A "length at maturity" (L) is defined, and a method for synthesizing the data is ... -
Maximization of fitness by phenological and phenotypic plasticity in range expanding rabbitfishes (Siganidae)
(Peer reviewed; Journal article, 2022)Global warming is modifying the phenology, life-history traits and biogeography of species around the world. Evidence of these effects have increased over recent decades; however, we still have a poor understanding of the ... -
Maximizing sampling efficiency to detect differences in fish community composition using environmental DNA metabarcoding in subarctic fjords
(Peer reviewed; Journal article, 2023)Environmental DNA (eDNA) has gained popularity as a tool for ecosystem biomonitoring and biodiversity assessment. Although much progress has been made regarding laboratory and fieldwork protocols, the issue of sampling ... -

Målinger av brislingmengde med ekkointegrator i vestnorske fjorder høsten 1972
(Fisken og havet, Research report, 1973)An echo survey for O-group sprat in the fjords of western Norway was carried out in late October 1972. An outline of the distribution is given together with relative estimates of abundance. Measures of abundance are ... -
