Yngelproduksjon av gadoider: utvikling av intensiv oppdrettsmetode for torsk og hyse
(Fisken og havet, Research report, 2001)Oppdrett av torskeyngel har stort sett vært basert på produksjon i ekstensive systemer (poller eller store sjøvannsbassenger) med utelukkende bruk av naturlig forekommende zooplankton som for. Slike systemer er imidlertid ... -

Ytre Oslofjord - overvåkning av eutrofitilstanden 1999-2000
(Fisken og havet, Research report, 2001)Observasjonene av miljøforholdene i 1999 og 2000 i ytre Oslofjord viste at øvre lag hadde betydelige overkonstrasjoner særlig av nitrat og høye N/P forhold sammenlignet med kystområdene i indre Skagerrak. De menneskeskapte ... -
Zinc uptake in fish intestinal epithelial model RTgutGC: Impact of media ion composition and methionine chelation
(Journal article; Peer reviewed, 2018)Apical uptake of zinc as ionic Zn(II) or as Zn-methionine (Zn-Met) was studied in RTgutGC cell line in vitro under media compositions mirroring the gut luminal ionic concentration of freshwater (FW) and seawater (SW) ... -
Zoantharians (Hexacorallia: Zoantharia) associated with cold-water corals in the azores region: New species and associations in the deep sea
(Journal article; Peer reviewed, 2017)Zoantharians are a group of cnidarians that are often found in association with marine invertebrates, including corals, in shallow and deep-sea environments. However, little is known about deep-sea zoantharian taxonomy, ... -
Zooplankton and the discontinuity layer in relation to echo traces in the Oslofjord
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1969)1. Using high amplification on the 38.5 Kc/sec. echosounder echoes from the depth of the discontinuity layer in the inner Oslofjord were mostly observable. 2. The distribution of zooplankton was analysed from samples ... -
Zooplankton growth, diet and reproductive success compared in simultaneous diatom- and flagellatemicrozooplankton-dominated plankton blooms
(Journal article; Peer reviewed, 2001-10-18)Development of mesozooplankton biomass, feeding activity and reproductive success of the copepod Calanus helgolandicus were compared in blooms of natural plankton in 7 mesocosms on the west coast of Norway between 28 August ... -
