“…Deformities were predominantly located in the cranial trunk (R1) and tail fin (R4), consistent with other reports in S1+ unvaccinated smolts (Fraser et al, 2014). Furthermore, the pathology type, principally compressions, did not differ between dietary pospholipid source.…”

The present study aimed to confirm the requirement for dietary phospholipid in Atlantic salmon and better define the level and period of requirement. Thus, the effects of dietary supplementation with phospholipid supplied by krill or soy lecithin were investigated in Atlantic salmon, Salmo salar. First feeding fry were fed diets containing 55 % protein and 17 % lipid supplemented with krill oil or soybean lecithin in a regression design at five levels, 1.5 (unsupplemented), 2.6, 3.2, 3.6 and 4.2 % total phospholipid and fish were sampled at 1 g (1400 ˚day post fertilisation, dpf), 2.5 g (1990 ˚dpf), 5 g (2350 ˚dpf), 10-20 g (2850 ˚dpf) and smolt (3800 ˚dpf). Survival was high overall with a positive correlation (r 2 = 0.59 -0.72) between survival and dietary phospholipid supplementation. Growth was improved by phospholipid with highest growth achieved in fish fed krill phospholipid at 2.6 % and in fish fed soy lecithin at 3.6 %. The pattern of growth differed between fish up to 2.5 g and that from 2.5 g onwards with SGR (0-2.5 g) being significantly higher in fish fed 2.6 % krill phospholipid and 3.6 % soy phospholipid compared to the basal diet, whereas there was no difference in SGR (2.5g-smolt) between the treatments. Intestinal steatosis was observed in 2.5 g fish fed the unsupplemented diet (20 % prevalence) and lower levels of soy (10 % prevalence), whereas it was absent from 2.5 g fish fed krill oil and higher levels of soy lecithin (≥ 3.2 %), and fish at all later stages. Prevalence of vertebral deformities was low but was reduced by increasing dietary phospholipid with krill oil generally being more effective.The results were consistent with salmon having a dietary requirement for dietary phospholipid in early life stages.3

“…Furthermore, irrespective of the ploidy, more vertebrae and more regions displayed deformities in the elevated treatment compared to the standard treatment similarly to Fraser et al . (). This implies an effect of temperature and as a consequence of higher SGR, as observed in our study, on regional occurrence of vertebral deformities.…”

Triploid Atlantic salmon tend to develop a higher prevalence of skeletal anomalies. This tendency may be exacerbated by an inadequate rearing temperature. Early juvenile all-female diploid and triploid Atlantic salmon were screened for skeletal anomalies in consecutive experiments to include two size ranges: the first tested the effect of ploidy (0.2-8 g) and the second the effect of ploidy, temperature (14 °C and 18 °C) and their interaction (8-60 g). The first experiment showed that ploidy had no effect on skeletal anomaly prevalence. A high prevalence of opercular shortening was observed (average prevalence in both ploidies 85.8%) and short lower jaws were common (highest prevalence observed 11.3%). In the second experiment, ploidy, but not temperature, affected the prevalence of short lower jaw (diploids > triploids) and lower jaw deformity (triploids > diploids, highest prevalence observed 11.1% triploids and 2.7% diploids) with a trend indicating a possible developmental link between the two jaw anomalies in triploids. A radiological assessment (n = 240 individuals) showed that at both temperatures triploids had a significantly (P < 0.05) lower number of vertebrae and higher prevalence of deformed individuals. These findings (second experiment) suggest ploidy was more influential than temperature in this study.
