“…This decline in T opt SGR with increasing weight is in accordance with growth studies for juvenile cod (Jobling 1988;Otterlei et al 1999;Björnsson et al 2007), juvenile turbot (Imsland et al 1996;Arnason et al 2009), plaice (Fonds et al 1992), spotted wolffish (Imsland et al 2006) and Atlantic halibut (Hallaraker et al 1995;Bjornsson & Tryggvadottir 1996;Jonassen et al 1999). The observed scope for T opt SGR in this study is similar to that proposed for halibut by Hallaraker et al (1995) (10.0 -13.0 °C for 20 -90 g) and Bjornsson…”

“…In our study the indications of an ontogenetic shift were prominent from period 3 (3 June -26 June, FIGURE 3.3 and Appendix II). In contrast, the time span proposed for experiment 2 is suggested to be too short to observe any effects of temperature on feeding regime (Björnsson et al 2007), as no effects on FCE or F were observed in this study.…”

“…The lack of difference in observed FCE and F % between S-AMB and S13 may be explained by only two replicates per group and a short sampling period (17 days) to observe an effect of increased temperature. The lack of difference in temperature effect has also been shown in experiments for juvenile Atlantic cod (Björnsson et al 2007). Björnsson et al (2007) stated that adaption time for fish reared at high temperatures is longer than that of fish reared at low temperatures.…”

“…Despite consistency in the findings of increased final weight with increasing temperature, these comparisons of final weight between studies do not take into consideration possible effects of different photoperiods (Jonassen et al 2000b;Imsland & Jonassen 2001;Lohne et al 2012), feeding regimes (Brown et al 1997) and time scopes (Björnsson et al 2007;Arnason et al 2009). …”

“…The time span of experiment 1 was approximately 3 months, which is thought to be sufficient to evaluate the temperature effects on growth in juvenile marine fish (Imsland et al 2005;Björnsson et al 2007;Imsland et al 2007b) and subsequently to provide evidence of differences in size due to temperature manipulation and hence the establishment of T opt SGR for different size groups. In our study the indications of an ontogenetic shift were prominent from period 3 (3 June -26 June, FIGURE 3.3 and Appendix II).…”

In recent lab‐based experiments, some post‐smolt Atlantic salmon (Salmo salar) held at 3°C for 5 weeks exhibited a range of clinical signs. They became lethargic and swam at the water's surface, developed ulcers to the head and jaw (clinical signs similar to tenacibaculosis in Norwegian salmon aquaculture) and had fin erosion, and this was associated with significant mortalities. In addition, when fish with ‘early’ and ‘advanced’ stages of these different clinical signs were further examined, their livers were found to be large, pale and friable. Fish with this aetiology also had elevated aspartate aminotransferase levels (indicative of liver damage), elevated plasma [Na+], [Cl−] and osmolality (indicating osmoregulatory impairment), low glucose levels (likely limiting metabolic responses to maintain homeostasis) and high circulating cortisol levels (∼100 ng/mL). This suite of physiological disturbances is very similar to that observed in a condition referred to as ‘Winter Syndrome’ or ‘Winter Disease’ (WS/WD) in cultured gilthead sea bream (Sparus aurata) and other fish species. Thus, it appears that WS/WD described here for the first time in Atlantic salmon, alone or in combination with opportunistic infections, results in lipid deposition in the liver, compromising liver function and osmoregulatory capacity, and metabolic collapse that ultimately results in significant losses.
