Approaches to optimize marine larvae production
Nicolaisen, Ove (PhD in Aquatic Biosciences;no. 27, Doctoral thesis, 2018) -
Cannibalism and protective behavior of eggs in Arctic charr (Salvelinus alpinus)
Frye, Marilena; Egeland, Torvald Blikra; Nordeide, Jarle Tryti; Folstad, Ivar (Peer reviewed; Journal article, 2021)From video recordings of spawning events, we quantified protective and cannibalistic behavior of Arctic charr occurring immediately after spawning. The number of fish cannibalizing on stray eggs was examined regarding (a) ... -
Carotenoids-based reddish pelvic spines in nonreproducing female and male sticklebacks (Gasterosteus aculeatus) – Signalling social dominance?
Kroken, Karl Kristian; Sæthre, Axel Aas; Nicolaisen, Ove; Egeland, Torvald Blikra; Nordeide, Jarle Tryti (Peer reviewed; Journal article, 2001) -
Cohabitation With Atlantic Salmon (Salmo salar) Affects Brain Neuromodulators But Not Welfare Indicators in Lumpfish (Cyclopterus lumpus)
Staven, Fredrik Ribsskog; Gesto, Mauel; Iversen, Martin Haugmo; Andersen, Per; Patel, Deepti Manjari; Nordeide, Jarle Tryti; Kristensen, Torstein (Peer reviewed; Journal article, 2022) -
Conspicuous carotenoid-based pelvic spine ornament in three-spined stickleback populations – occurrence and inheritance
Amundsen, Cesilie Røtnes; Nordeide, Jarle Tryti; Gjøen, Hans Magnus; Larsen, Berner; Egeland, Einar Skarstad (Journal article; Peer reviewed, 2015) -
Does egg carotenoid improve larval quality in Arctic charr (Salvelinus alpinus)?
Egeland, Torvald B.; Egeland, Einar Skarstad; Nordeide, Jarle Tryti (Peer reviewed; Journal article, 2022)Females in mutually ornamented species are often less conspicuously ornamented than their male conspecifics. It has been hypothesized that offspring quality may de-crease if females invest more resources into ornaments at ... -
Evolutionary genomics of pelvic spine reduction in Gasterosteus aculeatus
Adhikari, Dhurba (PhD in Aquatic Biosciences;no. 61, Doctoral thesis, 2024) -
Fish sperm competition in hatcheries and between wild and hatchery origin fish in nature
Beirão, José; Egeland, Torvald B.; Purchase, Craig; Nordeide, Jarle Tryti (Journal article; Peer reviewed, 2019) -
Interaction studies on lumpfish exposed to Atlantic salmon : behavioural observations and the underlying physiological and neurobiological mechanisms
Staven, Fredrik Ribsskog (PhD in Aquatic Biosciences;No. 43, Doctoral thesis, 2022) -
Is habituation measurable in lumpfish cyclopterus lumpus when used as cleaner fish in Atlantic salmon Salmo salar aquaculture?
Staven, Fredrik Ribsskog; Nordeide, Jarle Tryti; Imsland, Albert; Andersen, Per; Iversen, Nina Skorstad; Kristensen, Torstein (Journal article; Peer reviewed, 2019)To investigate how lumpfish interact in Atlantic salmon aquaculture, physiological stress responses and changes in behaviour were analysed in experienced and naive lumpfish. Experienced lumpfish (30.2 ± 7.93 g, mean ± SD) ... -
No support for cryptic choice by ovarian fluid in an external fertilizer
Kleppe, April Snøfrid; Nordeide, Jarle Tryti; Rudolfsen, Geir; Figenschou, Lars; Larsen, Berner; Reiss, Katrin; Folstad, Ivar (Journal article; Peer reviewed, 2018) -
On the relative effect of spawning asynchrony, sperm quantity, and sperm quality on paternity under sperm competition in an external fertilizer
Egeland, Torvald Blikra; Rudolfsen, Geir; Nordeide, Jarle Tryti; Folstad, Ivar (Journal article; Peer reviewed, 2015) -
Pitx1 enhancer variants in spined and spine-reduced Subarctic European sticklebacks

Spawning behavior of Arctic charr (Salvelinus alpinus) : Spawning synchrony, vibrational communication, and mate guarding
Brattli, Magnus B.; Egeland, Torvald Blikra; Nordeide, Jarle Tryti; Folstad, Ivar (Journal article; Peer reviewed, 2018)A mismatch in synchrony between male and female gamete release in external ferti - lizers can result in reduced or failed fertilization, sperm competition, and reduced paternity. In Arctic charr ( Salvelinus alpinus ), ... -
Status Specific Tailoring of Sperm Behavior in an External Fertilizer
Egeland, Torvald Blikra; Rudolfsen, Geir; Nordeide, Jarle Tryti; Folstad, Ivar (Journal article; Peer reviewed, 2016)
