“…Factors such as genetics (McKay & Gjerde 1986, Gjerde et al 2005, oxytetracycline administration (Toften & Jobling 1996), diet composition (Vielma & Lall 1998, Ørnsrud et al 2002, and incubation temperature (Takle et al 2005) may be involved in the development of deformed vertebrae.…”

In August 1998, 3000 Atlantic salmon Salmo salar L. parr were divided into 7 groups with 2 replicates. Every 6 wk until March of the following year 1 group was vaccinated. One group was held as an unvaccinated control. The fish were transferred to seawater in May 1999, and slaughtered in February 2000. Temperature, fish size and photoperiod at vaccination, and the time between vaccination and sea transfer thus varied among the groups. In all vaccinated groups, growth was reduced for 1 to 2 mo following vaccination. Intra-abdominal lesions developed faster, and stabilised at a higher level in the groups vaccinated early at the highest temperature and the smallest fish size. Growth in seawater was influenced by the time of vaccination. At the end of the experiment, the group vaccinated last (MAR) was the heaviest of the vaccinated groups (4.0 kg), and the group vaccinated first, i.e. in August (AUG) was smallest (3.2 kg). Growth rate in seawater differed only in the summer when specific growth rate was above 1.45 in all groups. There was a correlation between adhesion, condition factor and number of weeks from vaccination to sea transfer. The AUG group had the highest condition factor, with a top level of 1.64 in autumn, and this group also displayed the highest incidence of deformed vertebra. The experiment shows that side effects of vaccination can be significantly reduced when planning the vaccination strategy, by taking environmental factors and fish biology into consideration.

“…In addition, the impact of early life temperatures on bone homeostasis have not previously been studied in adult teleost fish. Most of the studies that exist have looked at the effect of increased temperature on skeletal development in species such as tilapia (Campinho et al, 2004), European sea bass Dicentrarachus labrax (Koumoundouros et al, 2001), Atlantic salmon (Takle et al, 2005) and gilthead sea bream (Boglione and Costa, 2011), or how it affects the incidence of malformations, an issue of importance to aquaculture (Boglione et al, 2013;Koumoundouros, 2010).…”

Fish are ectotherms and temperature plays a determinant role in their physiology, biology and ecology, and is a driver of seasonal responses. The present study assessed how thermal imprinting during embryonic and larval stages modified the response of adult fish to low water temperature. We targeted the gilthead sea bream, which develops a condition known as winter syndrome when it is exposed to low water temperatures. Eggs and larvae of sea bream were exposed to four different thermal regimes and then the response of the resulting adults to a low temperature challenge was assessed. Sea bream exposed to a high-low thermal regime as eggs and larvae (HLT; 22°C until hatch and then 18°C until larvae-juvenile transition) had increased plasma cortisol and lower sodium and potassium in response to a cold challenge compared with the other thermal history groups. Plasma glucose and osmolality were increased in coldchallenged HLT fish relative to the unchallenged HLT fish. Cold challenge modified bone homeostasis/responsiveness in the lowhigh thermal regime group (LHT) relative to other groups, and ocn, ogn1/2, igf1, gr and trα/β transcripts were all downregulated. In the low temperature group (LT) and HLT group challenged with a low temperature, alkaline phosphatase (ALP) and tartrate-resistant acid phosphatase (TRAP) activities were decreased relative to unchallenged groups, and bone calcium content also decreased in the LT group. Overall, the results indicate that thermal imprinting during early development of sea bream causes a change in the physiological response of adults to a cold challenge.

“…However, Stefanovic et al (48) measured hsp70 expression in lake whitefish on day 102 after fertilization, whereas embryos in this study were irradiated on day 7 after fertilization. The magnitude and timing of the stress response in fish is known to change throughout development (49), and the induction of hsp70 may be shorter lived earlier in development. The differential response between the 6-and 24-h time points may also be due to other factors involved in the adaptive response, such as DNA repair pathways, reactive oxygen scavengers or immune modulation.…”
