Summary: This study examined the efficacy of repeated Montreal Imaging Stress Test in reproducing stress reactivity patterns across two different designs. While stress reactivity was comparable between repeated sessions, differences in heart rate and cortisol response indicate that further adjustments to the task may be necessary for improved consistency. Task design was highlighted as an important factor in repeated stress reactivity.

Summary: In contemporary aquaculture, the inclusion of plant-protein sources is common practice. However, this may lead to an unbalanced supply of nutrients, such as taurine. Taurine plays important roles in lipid metabolism, and this study aimed to evaluate the effects of taurine supplementation to plant-based diets on the metabolism of taurine and lipids in Senegalese sole.

Summary: This study investigated the effects of treatments with homologous recombinant follicle-stimulating and luteinizing hormones on sperm production in sole. The results showed that these treatment increased gonad weight, stimulated spermatogenesis, and enlarged the size of the seminiferous and efferent ducts. Sperm production peaked at 48 hours after luteinizing hormone treatment, and low doses of follicle-stimulating hormone were highly efficient in stimulating sperm production when luteinizing hormone was administered at a temperature close to that occurring during maximum natural spermiation.

Summary: Humans exhibit habituation to aversive events, but little is known about the physiological and neural responses that contribute to stress habituation. This study used a variety of physiological measures and advanced analysis techniques to investigate the stress response to repeated exposure to the cold pressor test (CPT). The results revealed diverse adaptive changes in stress responses and demonstrated the process of habituation.

Summary: The ultrasound approach can accurately predict the fillet volume of Senegalese sole, showing promise for measuring in vivo fish composition traits. However, the results for fillet yield estimation were more modest, indicating the need for further studies to fully understand the potential of ultrasound in this trait.

Summary: The study revealed significant differences in immune responses triggered by different recombinants in infected sole, with the RNA2 mutant causing the most prominent immune response changes, especially the exclusive and high upregulation of genes related to the complement system. Infection with RNA1 mutants also led to reduced mortality and delayed replication compared to wt160, potentially causing the observed lag in immune response.

Summary: The transcriptomic response of Senegalese sole to two betanodaviruses with different virulence levels was studied, revealing that the highly virulent strain induced a stronger immune response but also increased disease severity, while the moderately virulent strain did not. Furthermore, specific genes showed significantly increased expression levels after infection with the highly virulent virus, while immune response was lacking after infection with the mutant strain.

Summary: This study investigated the genetic parameters of four growth traits in Senegalese sole, finding that females grew faster than males, there was high variation of sex ratios by family, and high heritabilities and genetic correlations among traits. Using a low-density SNP array, two significantly-associated SNPs with most of the traits at both ages were located in gtf3c4 and mtfp1, which are relevant for genetic breeding programs in this species.

Summary: This study evaluated the impact of biofortified diets containing microalgae, macroalgae, and selenised yeast on gilthead seabream. The results showed that microalgae can partially replace fish meal and fish oil in the diets for seabream. The addition of macroalgae and selenised yeast should be controlled at proper levels. The muscle of seabream fed with microalgae diets had higher EPA and DHA content, and their retention and gain of selenium were also increased. However, more research is needed for iodine fortification in fish.

Summary: This study presents novel findings on the impact of neuromodulators from Atlantic salmon interaction in the lumpfish brain. The results show that growth, health scores, and body color of lumpfish remained unaffected by exposure to salmon or salmon cues. This indicates that the welfare of lumpfish was not impacted by the presence of salmon in the laboratory setup.

Summary: Mathematical models can be used to estimate the body composition of fish without sacrificing animals. In this study, Nile tilapia body composition data were collected from 138 scientific publications, and predictive models were developed using different combinations of models and calibration methods. The results showed that model predictions are influenced by the type of model, calibration method, and amount of calibration data available. The best predictive models for Nile tilapia body composition were the allometric model and a robust hybrid model, both calibrated assuming multiplicative error.

Summary: Rising levels of atmospheric CO2 are causing ocean warming and acidification, which have potential negative effects on commercially important fish species. This study examined the effects of ocean acidification (OA) and warming (OW), both individually and combined, on the composition, fitness, and energy budget of juvenile Senegalese sole. The results showed that acidification and warming did not significantly impact the proximate composition and gross energy of the fish. However, OA, OW, and OAW treatments resulted in higher growth rates, metabolic rates, and energy intake compared to control conditions. The study highlights the physiological responses of juvenile Senegalese sole to ocean warming and acidification, emphasizing the importance of understanding the impact of climate change on fisheries.

Summary: This study aimed to investigate the amino acid sensing capacity and hormone production in the gastrointestinal tract (GIT) of rainbow trout in response to proline, fishmeal amino acids, and fishmeal aqueous extract. The results showed that the presence of proline in the GIT led to changes in amino acid sensing systems and hormone production, especially in the proximal regions, accompanied by anorectic response in the hypothalamus. Both the fishmeal aqueous extract and the fishmeal amino acids induced anorectic responses in the hypothalamus, accompanied by increased production of anorectic hormones in the intestine.

Summary: Aquaculture intensification is often linked to disease outbreaks, but nutritional approaches, such as algae-derived compounds, can help alleviate the burden caused by diseases. This study evaluated the immunomodulatory activity of an algae blend on farmed seabass's resistance to a bacterial pathogen. The results showed that a 4% inclusion level of the algae blend was the most effective in preventing adhesion and colonization of the pathogen on mucosal tissues, leading to reduced disease progression and mortality.

The results showed that replacing 50% of fishmeal protein with defatted Tenebrio molitor significantly improved feed efficiency without affecting fish growth performance. The nutritional and sensory quality traits of the fish fillets were similar between the control and defatted Tenebrio molitor groups.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
