Publikasjoner
NIBIOs ansatte publiserer flere hundre vitenskapelige artikler og forskningsrapporter hvert år. Her finner du referanser og lenker til publikasjoner og andre forsknings- og formidlingsaktiviteter. Samlingen oppdateres løpende med både nytt og historisk materiale. For mer informasjon om NIBIOs publikasjoner, besøk NIBIOs bibliotek.

The use of wrasse (F. Labridae) as biological cleaner-fish in the control of salmon lice has been demonstrated in a number of studies and they are successfully used on a large scale, with over two million wrasse being caught and stocked annually, in commercial salmon farms in Norway. Increasingly, efforts are being made to produce commercial stocks of wrasse for use on farms and an EU Northern Periphery Project entitled "Ecofish" has been established to develop the technologies for spawning and rearing the most promising cleaner fish, ballan wrasse, in captivity with dedicated production hatcheries will be established in Ireland, Norway and Scotland. This project will also look into the management of ballan wrasse in salmon cages in order to achieve the effective removal of lice. As part of the Ecofish work programme, this study examined the embryonic development of Ballan wrasse using material from a series of spawnings in Ireland and Norway. The overall development from fertilization to hatch was monitored and recorded and a standardized series of developmental stages are assigned, from zygote through cleavage, blastulation, gastrulation, segmentation to hatching: each with specific morphological landmarks. This standardization and the synchronization of the developmental stages will facilitate future studies with the species as we may be better able to compare the development rate of different geographic stocks and under different environmental conditions. The developing embryo was also staged at three different incubation temperatures; 10.5oC, 12.9 oC, and 16.5 oC with 50% hatched occurring at 171, 121 ands 96 hours post fertilisation respectively.

A wide range of compounds originating from everyday products with beneficial qualities for humans are transferred to the environment and potentially to animal- and human food-chain. Many of these compounds are emerging contaminants that are perceived or with real human and environment health hazard. Environmental and health risk assessment for these compounds is difficult (hard?) to performed due to lack of essential knowledge. In order to gain an overall view of needed knowledge and which knowledge gaps there are, we have applied a “from the cradle to the grave” approach and evaluated the compounds pathway from sources and fate in environment and transfer to human food items. The present study provides significant insights and information for evaluating the potential health hazards of these chemicals.

Skog og landskap undersøker produksjonsevnen i mange forskjellige treslag, deriblant det fremmede nordamerikanske trelaget hemlokk. Hemlokk er blant annet plantet i et forsøksfelt i Stendadalen opp mot Stendafjellet på eiendommen til Stend videregående skole. Trærne der er nå over 80 år gamle, og det høyeste treet i feltet er blitt hele 38 meter, mens det grøvste treet er 57 centimeter i brysthøydediameter. Hemlokk er et treslag som produserer mye biomasse på Stend. Imidlertid forynger og sprer hemlokk seg lett i og rundt forsøksfeltet og er derfor planlagt hogget denne sommeren. Virket blir sannsynligvis levert til Tyskland.
