Andre samlerapport: velferd for triploid laks i Nord-Norge - Sluttrapport, utsett 2018

Denne rapporten tar for seg velferden til 8 grupper av triploid laks satt ut i Nord-Norge vår, sommer og høst 2018. Vårutsettene fikk varierende velferd og dødelighet. Dette skyltes i stor grad at disse fiskegruppene hadde med seg iboende svakheter fra settefiskfasen. Sommerutsettene unngikk parvikapsulose og (som forventet) fikk lav dødelighet, mens høstutsettene fikk høy dødelighet. Begge gruppene med triploid laks satt ut om høsten fikk utbrudd av parvikapsulose og vintersår. Disse resultatene stemmer godt overens med resultatene fra første samlerapport for 2014-2017 generasjonene. Av de 8 gruppene med triploid laks satt ut i 2018 fikk 3 påvist ILA og måtte destrueres. Så langt i prosjektet (alle generasjoner, 2014-2018) har 70% av de triploide vårutsettene, 55 % av sommerutsettene og 0 % av høstutsettene med triploid laks hatt merder som oppnådde lav snittdødelighet for hele produksjonen.publishedVersio

Still Arctic? — The changing Barents Sea

The Barents Sea is one of the Polar regions where current climate and ecosystem change is most pronounced. Here we review the current state of knowledge of the physical, chemical and biological systems in the Barents Sea. Physical conditions in this area are characterized by large seasonal contrasts between partial sea-ice cover in winter and spring versus predominantly open water in summer and autumn. Observations over recent decades show that surface air and ocean temperatures have increased, sea-ice extent has decreased, ocean stratification has weakened, and water chemistry and ecosystem components have changed, the latter in a direction often described as “Atlantification” or “borealisation,” with a less “Arctic” appearance. Temporal and spatial changes in the Barents Sea have a wider relevance, both in the context of large-scale climatic (air, water mass and sea-ice) transport processes and in comparison to other Arctic regions. These observed changes also have socioeconomic consequences, including for fisheries and other human activities. While several of the ongoing changes are monitored and quantified, observation and knowledge gaps remain, especially for winter months when field observations and sample collections are still sparse. Knowledge of the interplay of physical and biogeochemical drivers and ecosystem responses, including complex feedback processes, needs further development.Still Arctic? — The changing Barents SeapublishedVersio
