HAVBRUKS-Havbruk - en næring i vekst

Production of all-female cod as a means to circumvent problems with early puberty in males: Studies on sex determination and differentiation

Early puberty is a major problem in cod farming both due to negative impact on production performance in on-growth farms, and due to risk of negative genetic impact on wild stocks following spawning in sea cages or after escape. Use of all-female stocks c an mitigate some of these problems. Howev...

Background levels: Occurrence and effective detection of cod pathogens

Cod farming is considered one of the areas with the highest potential for growth in Norwegian aquaculture. Most cod hatcheries use wild caught broodstock, which represent a danger for the contamination of the farm premises with pathogens (virus, bacteria, parasites); particularly those transmitt...

Effects of vaccination and innate immune defence against recurrence of IPN in salmon carrying IPN virus of different virulence.

There is a need to identify factors that may contribute to the serious infectious pancreatic necrosis (IPN) disease problems in A. salmon post-smolts. It is important to know more about the impact of the widespread carrier state of IPNV in A. salmon, the risk of recurrence of IPN, and the high vi...

Jerntoksisitet i norske settefiskanlegg - oppskalering og utprøving av vannbehandling med silikat og/eller sjøvann

Basert på VK databasen samt en rekke henvendelser fra norske settefiskanlegg til NIVA i perioden 1999 - 2003 ble det klart at toksisitet av jern var et større problem enn antatt for settefisknæringen i Norge. VK-dataene viser også tydelig at det er anlegg i Midt-Norge som har de største probleme...

Alphavirus (Togaviridae) fra laksefisk i norsk oppdrett. Karakterisering, vertikal overføring og studie av vevs/celle-tropisme.

Salmon pancreas disease (SPD) ble først beskrevet fra Skottland i 1984, men var sannsynligvis tilstede i oppdrett av laks i Skottland så tidlig som i 1976. I 1990 ble det vist at sykdommen hadde en infeksiøs årsak. Senere, i 1995, ble det klart at sykdomm en skyldes et togaviruslignende agens som...

Marker-Assisted Selection for IPN resistance in Atlantic salmon

IPN is a major problem in salmon farming. DNA markers linked to resistance genes could be used to improve selection for resistance, through MAS. Here, we propose to combine experimental and theoretical approaches to lay the foundations for MAS on IPN in A tlantic salmon. Genetic material for the...
