Supplementation of dietary minerals during the early seawater phase increase vertebral strength and reduce the prevalence of vertebral deformities in fast‐growing under‐yearling Atlantic salmon (Salmo salar L.) smolt
Per Gunnar Fjelldal,Thomas Willum Hansen,O. Breck,R. Sandvik,Rune Waagbø,A. Berg,Robin Ørnsrud +6 more
TL;DR: Elevated dietary mineral content during the early SW phase may reduce the prevalence of vertebral deformities in fast growing 0 + salmon smolts, and plasma levels of Ca, P and D-vitamin metabolites recorded in week 8 reflected changes in P homeostasis.

Vertebral deformities in farmed Atlantic salmon (Salmo salar L.) – etiology and pathology
Per Gunnar Fjelldal,Thomas Willum Hansen,O. Breck,Robin Ørnsrud,Erik-Jan Lock,Rune Waagbø,Anna Wargelius,P. Eckhard Witten +7 more
TL;DR: More research is needed to under- stand the interdependency of genetics, development, aging, phosphorus nutrition, temperature and photoperiod, in order to establish the best practice procedures for salmon farming that improve fish welfare.

Histidine nutrition and genotype affect cataract development in Atlantic salmon, Salmo salar L.
TL;DR: Investigation of effects of dietary levels of histidine (His) and iron (Fe) on cataract development in two strains of Atlantic salmon monitored through parr-smolt transformation concluded that histidine supplementation had a positive effect on growth performance and feed conversion ratio, whereas this did not occur when iron was added.

Cataract preventative role of mammalian blood meal, histidine, iron and zinc in diets for Atlantic salmon (Salmo salar L.) of different strains
TL;DR: The data suggest that elevated concentrations of dietary His and/or Fe mitigate cataract formation in Atlantic salmon, and this effect may be related to maintaining vision and feed uptake ability.

Effect of water oxygen level on performance of diploid and triploid Atlantic salmon post-smolts reared at high temperature
Tom Johnny Hansen,Rolf Erik Olsen,Lars Helge Stien,Frode Oppedal,Thomas Torgersen,O. Breck,Mette Remen,Tone Vågseth,Per Gunnar Fjelldal +8 more
TL;DR: An interesting difference in the behavior between diploid and triploid fish was observed during the experiment: triploids generally moved against the tank water current, ram ventilating, as opposed to diploids, which displayed normal gill ventilation and were in part moving along with the current.
