Differential gene expression analysis reveals functional roles of cryptic orange-pigmented organ in the colorless head kidney of Antarctic icefishes
… within the anterior end of the colorless head kidney of the hemoglobinless Antarctic icefishes. No macroscopically visible discrete organ has previously been reported in Antarctic fishes or teleost fishes in general. To assess the tissue type and functions of this cryptic orange body, we …

Metabolic, neurotoxic and immunotoxic effects of PFAAs and their mixtures on the proteome of plasma and head kidney from rainbow trout
… were conducted on the blood plasma and head kidney tissue to evaluate differences in biological effect for congeners and mixtures. The mixture and PFOS exposures significantly altered the abundances of many plasma proteins involved in lipid metabolism and the nervous system. The PFOA and …

The Roles of Social Status, Maternal Stress, and Parental Investment in Modulation of Hypothalamic-Pituitary-Interrenal Axis Function in Teleost Fish
… stressor were attenuated. Using an in vitro head kidney preparation, this attenuated cortisol response was attributed to lower ACTH-stimulated production of cortisol. By contrast, dominant status regulated genes associated with cortisol biosynthesis. The consequences of maternal social status …

Pathogenic mechanisms of Photobacterium damselae subspecies piscicida in hybrid striped bass
… (EPC), channel catfish ovary (CCO), and fathead minnow (FHM) cells lines was also evaluated using an in vitro invasion assay. All three cell lines were susceptible to invasion and supported replication of P. damselae. Fathead minnow cells were more susceptible to invasion than the other two …

Immune and Endocrine Modulations Associated with Enhanced Plant-Based Protein Diets Within Freshwater Fish Species
… and superoxide production of yellow perch head-kidney macrophages. Analysis of respiratory burst activity (RBA) after 46 days of treatment were found to be significantly different across dietary treatments (PFlavobacterium psychrophilum (17830), a major salmonid pathogen in commercial …

Investigating the potential utilisation of black soldier fly (Hermetia illucens) as an alternative protein source in tilapia and carp feed
… (il1β, tnfα, il10) in either the intestine or head kidney were not significantly affected, but slc15a1a was upregulated at 40% BSF meal compared with the control.<br/>Similar results were obtained in juvenile mirror carp fed the same BSF meal at 20% and 40% over 8 weeks, replacing mainly SBM …

Evaluating the efficacy of brewers’ yeast-derived functional feed additives in mitigating soybean meal-induced enteritis in Atlantic salmon
… and antimicrobial markers in the head kidney and increased mucosal gene activity in the skin, suggesting coordinated cross-tissue responses.<br/>Together, the results demonstrate that yeast-derived additives exert targeted and context-sensitive effects on mucosal health in Atlantic …

Applying edge-core theory of intraspecific life-history variation to the control of invasive silver carp (hypophthalmichthys molitrix)
… blood smears, hematocrit, hepatosomatic index, head kidney melanomacrophages, and health assessment index scores were compared between the Starved Rock and La Grange Reaches in 2018. Results from this study show that silver carp from ‘edge’ and ‘core’ reaches do not differ significantly in …
