The prevalence of vertebral deformities is increased with higher egg incubation temperatures and triploidy in Atlantic salmon Salmo salar L.

Abstract: Suboptimal egg incubation temperature is a risk factor for the development of skeletal deformities in teleosts. Triplicate diploid and triploid Atlantic salmon, Salmo salar L., egg batches were incubated at 6, 8 and 10 °C up until first feeding, whereupon fish were reared on a natural temperature before examination for externally visible skeletal deformities (jaw and spine) and radiographed for vertebral deformities and morphology at the parr stage. Increasing incubation temperatures and triploidy increased th… Show more

“…Only recently, development of LJD has been linked to dietary phosphorus (P) deficiency and a higher P requirement of triploid Atlantic salmon [8]. Nevertheless, the mechanisms underlying the onset of LJD are not known and could be multifactorial via a combination of genetic (triploidy and genetic background), nutritional (mineral or vitamin deficiency) and environmental (accelerated growth, low dissolved oxygen, elevated temperature and husbandry practices) factors [68, 14]. Although it seems to occur mostly during the freshwater phase, onset of LJD can occur at any time in development and prevalence and severity (i.e.…”

“…Although it seems to occur mostly during the freshwater phase, onset of LJD can occur at any time in development and prevalence and severity (i.e. worsening of the downward curvature) can increase over time [3, 4, 79, 11, 14, 15]. …”

“…The consequences of vertebral deformities for body shape depended on position along the vertebral column (Figure ). Frequency of spinal deformities varies among cultured fish species, with reports ranging from 7.7% in barramundi Lates calcarifer to 19% in Atlantic salmon (Fraser, Anderson, & de Nys, ; Fraser, Hansen, Fleming, & Fjelldal, ; Lü et al., ).…”
