“…Blood parameters determined after a single test in a T-maze were similar for both fish categories and were within the usual range of values for sea bass (Coeurdacier et al 1997;Dosdat et al 2003;Millot et al 2008). Only base excess, HCO 3 and total CO 2 differed significantly between categories, but the values obtained did not indicate any major physiological disturbance.…”

-Replacing aquaculture feeds based on fisheries-derived resources with plant-based diets could be a relevant strategy to improve the sustainability of aquaculture. Recent studies on sea bass have shown that the total and early replacement of marine products by plant products would have a moderate effect on fish growth and body lipid content. Whether a plant-based diet impacts behavioural and physiological traits possibly linked to fish welfare, is not known, however. Here, we studied the effect of a totally plant-based diet introduced at an early stage of sea bass development on self-feeding behaviour, learning ability in a T-maze and stress biomarkers. We first compared learning processes in selffeeding conditions, between naive fish fed a plant-based diet (PBF) and fish fed a classic marine diet (MF). Then, we tested fish individually in a T-maze to compare the two feed groups for swimming activity, exploration and the ability to learn to discriminate between two two-dimensional objects associated with a reward. Blood physiological variables, including stress indicators (cortisol and glucose concentrations), were also determined. We did not find any indications of differences in self-feeding behaviour between PBF and MF in the first 30 days. A second experiment showed similar swimming activities in both fish categories. The "no-choice" percentage was high in both fish categories (∼60%), but all the fish moved preferentially toward the reward. Their first turns indicated an ability to discriminate between two two-dimensional objects to complete a simple task. However, the high percentage of "no-choice" responses in both fish categories could have rendered the results non significant. The T-maze test procedure induced the production of high concentrations of cortisol, indicating acute stress in fish of both groups during testing. Plasma cortisol concentration was higher in MF than PBF, suggesting that the plant-based diet may affect the short-term release of cortisol. This study provides the first insight into the impact of a plant-based diet on sea bass behavioural traits, and confirms the effect of this diet on cortisol release in response to stress. Overall, in this first experiment, we did not find any major impact of a plant-based diet on sea bass behavioural traits, which is an interesting point for the development potential of such a sustainable aquaculture strategy.

“…It was presumed that the Ig molecules may recognize the bacterial pathogens during this period. This view was supported by research in sea bass, for which even down-regulation of the first month has been discovered which was explained as the Ig consuming for counteracting with antigen (Coeurdacier et al, 1997). In addition, the higher level of IgM expression in Group B also supports the view, and on the other hand indicated that boosted injection can enlarge the Ig producing reaction of first injection.…”

“…Total protein level and IgM level have been reported to increase in Atlantic salmon during aAS infection (Magna7ottir & Gudmunds7ottir 1992, Magna7ottir et al 1995. However, there was no significant correlation between the serum protein concentration and IgM level after Vibrio anguillarum infection (Coeurdacier et al 1997).…”

The Arctic charr Salvelinus alpinus is an endangered fish species in Finland, and thus farming is carried out mainly for stocking purposes. Farmed charr are susceptible to infection with atypical Aeromonas salmonicida (aAS). Losses of valuable brood stock will severely reduce the genetic diversity of stocked charr. No commercial vaccines are available to prevent aAS infection, and vaccines against furunculosis (caused by typical A. salmonicida, tAS) do not protect the charr against aAS infection.
