Pilot scale studies of intensive cod farming in Norway
(ICES CM Documents;1985/F:22, Working paper, 1985)Cod fry produced in a seawater pond at Austevoll, Norway were used in a farming experiment. Cod larvae were start fed on the natural plankton in the pond. Additional feeding with dry pellet started when the fry were 60 ... -

Pilotprosjekt for vurdering av samlet påvirkning i Oslofjorden – ytre del
(Rapport fra havforskningen;2024 - 15, Research report, 2024)Stor befolkningstetthet, høy menneskelig aktivitet og miljøutfordringer gjør at det er viktig å vurdere menneskelig påvirkning i Oslofjorden samlet. Denne rapporten presenterer en tverrsektoriell fremstilling av samlet ... -
Pingers reduce harbour porpoise bycatch in Norwegian gillnet fisheries, with little impact on day-to-day fishing operations
(Peer reviewed; Journal article, 2022)A field trial was conducted to determine the effect of acoustic deterrent devices (ADDs, or pingers) on harbour porpoise (Phocoena phocoena) and harbour seal (Phoca vitulina) bycatch in three Norwegian commercial gillnet ... -
Pinging down the food web: multi-frequency acoustic discrimination of jellyfish and fish
(ICES CM Documents;2004/R:6, Working paper, 2004)Jellyfish are gaining increasing prominence in many pelagic marine ecosystems worldwide. It has been argued that jellyfish-dominated communities will be the end-point in ecosystems perturbed by high fishing effort, and ... -

Piscivorous fish patrol krill swarms
(Journal article; Peer reviewed, 2005-09-01)Dense swarms of the krill Meganyctiphanes norvegica in the Norwegian Sea were patrolled by large, piscivorous fish, which apparently use the krill swarms as feeding grounds in their hunt for planktivores. For the krill, ... -
Pituitary Gonadotropin Gene Expression During Induced Onset of Postsmolt Maturation in Male Atlantic Salmon: In Vivo and Tissue Culture Studies
(Peer reviewed; Journal article, 2022)Precocious male maturation causes reduced welfare and increased production costs in Atlantic salmon (Salmo salar) aquaculture. The pituitary produces and releases follicle-stimulating hormone (Fsh), the gonadotropin ... -
The Piwil1 N domain is required for germ cell survival in Atlantic salmon
(Peer reviewed; Journal article, 2022)Genetic introgression of farmed salmon into wild populations can damage the genetic integrity of wild stocks and is therefore considered as an environmental threat. One possible solution is to induce sterility in farmed ... -
Planctomycetes as a vital constituent of the microbial communities inhabiting different layers of the meromictic Lake Sælenvannet (Norway)
(Peer reviewed; Journal article, 2020)Meromictic lakes are permanently stratified lakes that display steep gradients in salinity, oxygen and sulphur compounds tightly linked to bacterial community structure and diversity. Lake Sælenvannet is a meromictic lake ... -
Planktic foraminiferal and pteropod contributions to carbon dynamics in the Arctic Ocean (north Svalbard margin)
(Peer reviewed; Journal article, 2021)Planktic foraminifera and shelled pteropods are some of the major producers of calcium carbonate (CaCO3) in the ocean. Their calcitic (foraminifera) and aragonitic (pteropods) shells are particularly sensitive to changes ... -

Plankton community structure and fish spawning area indicators in the Bay of Biscay, using Laser Optical Plankton Counter
(ICES CM Documents;2005/P:13, Working paper, 2005)In the Bay of Biscay, regular fisheries acoustic cruises are conducted to assess small pelagic fish stocks. Within the frame of the Bay of Biscay integrated project, measurements of additional biotic and abiotic variables ... -

Plankton som råstoffkilde for fremstilling av fôrmidler til bruk innen fiskeoppdrett. Et forprosjekt. Delprosjekt: Utredning av forekomster og tilgjengelighet av dyreplankton.
(Interne notat, Working paper, 1999-06-04)Rapporten utreder forekomster av dyreplankton i det nordlige Atlanterhavet og Barentshavet. Det er lagt sarlig vekt på rauåte, krill, amphipoder og mesopelagisk makroplankton. Rapporten behandler tetthet, vertikalfordeling, ... -
Plankton succession and responses to manipulations in a marine basin for larval fish rearing
(Journal article; Peer reviewed, 1991-08-08)A marine basin was constructed in order to provide fish larvae a natural environment for growth and survival. In nature, similar enclosed systems are limited by stagnant water and anoxic conditions. Consequently, 3 types ... -
