Genetic analysis of goldsinny wrasse reveals evolutionary insights into population connectivity and potentialevidence of inadverent translocationvia aquaculture
Jansson, Eeva; Sanchez, Maria Quintela; Dahle, Geir; Albretsen, Jon; Knutsen, Halvor; André, Carl; Strand, Åsa; Mortensen, Stein; Taggart, John B.; Karlsbakk, Egil; Kvamme, Bjørn Olav; Glover, Kevin (Peer reviewed; Journal article, 2017)The salmon industry is heavily dependent on wrasse for delousing infected fish. The goldsinny wrasse is numerically the most important, and each year, millions are harvested from the wild and transported large distances ... -
Impact of hatch-date on early life growth and survival of Mueller's pearlside (Maurolicus Muelleri) larvae, and life-history consequences
Folkvord, Arild; Gundersen, Geir; Albretsen, Jon; Asplin, Lars; Kaartvedt, Stein; Giske, Jarl (Peer reviewed; Journal article, 2016-02)Growth and survival of Maurolicus muelleri larvae in Herdlefjorden, Norway, were investigated by daily otolith increment analysis. While high egg densities were generally observed throughout the spawning season, three ... -

Geffen, Audrey J.; Albretsen, Jon; Huwer, Bastian; Nash, Richard David Marriott (Journal article; Peer reviewed, 2021)Lemon sole Microstomus kitt is a commercially valuable flatfish species that occurs in shelf waters around the northeast Atlantic. Only the most basic life-history information is available for the North Sea. Spawning is ... -
Linking bacterial community structure to advection and environmental impact along a coast-fjord gradient of the Sognefjord, western Norway
Storesund, Julia Endresen; Sandaa, Ruth-Anne; Thingstad, T. Frede; Asplin, Lars; Albretsen, Jon; Erga, Svein Rune (Peer reviewed; Journal article, 2017-12)Here we present novel data on bacterial assemblages along a coast-fjord gradient in the Sognefjord, the deepest (1308 m) and longest (205 km) ice-free fjord in the world. Data were collected on two cruises, one in November ...
