Summary: This study purified the pigment of black sturgeon caviar and identified it as a typical black pigment through chemical degradation and electron paramagnetic resonance (EPR) evidence. Analysis of oxidative degradation mixtures revealed the formation of a specific marker of eumelanin pigments, providing a novel molecular basis for the valorization of black caviar and production wastes in food chemistry and diet.

Summary: The demand for caviar has risen due to its nutritional and commercial values, leading to a decline in wild sturgeon populations and a shift towards farmed caviar supply. The advancement of sturgeon aquaculture has spurred the search for alternatives. However, the emergence of caviar substitutes has also brought challenges such as commercial mimicry and fraud.

Summary: Sturgeons are highly valuable fish species and their wild populations are at the brink of extinction. To meet the high demand for caviar, aquaculture has been developed. However, correct species identification is necessary due to commercial fraud. This study introduces a new methodology for accurate species identification and also the identification of hybrids, contributing to the conservation of sturgeon populations and traceability of their products.

Summary: This study investigated the toxicity and metabolism mechanisms of ammonia in the hepatopancreas of female swimming crab. Ammonia exposure resulted in reduced vtg expression, inhibition of multiple signaling pathways, and alterations in energy metabolism. Furthermore, changes in antioxidant systems, protein and lipid oxidations, and cellular apoptosis were observed, indicating metabolic suppression, oxidative stress, and apoptosis in the hepatopancreas of P. trituberculatus.

Summary: In this study, the composition and flavor formation mechanism of sturgeon caviar were investigated. Multiple compounds were found to be associated with the flavor attributes of the caviar, and the variations in these compounds were correlated with fungal and bacterial genera. The results provide a foundation for targeted preservation and flavor control of caviar.

Summary: White sturgeon infected with Veronaea botryosa at high temperatures showed significantly increased expression levels of immune and inflammatory mediators. The expression of irf8 and tfg-beta genes were significantly higher in gills of fish exposed to the pathogen at 18°C. Higher levels of haptoglobin, serotransferrin, serum amyloid, cathelicidin, tnf-alpha, and il-17 transcripts were also detected in spleen tissues of infected fish maintained at 18°C during the later stage of infection.

Summary: Systemic phaeohyphomycosis caused by Veronaea botryosa is an important emerging mycotic disease in sturgeon aquaculture without any available vaccines or treatments. Dietary beta-glucan supplementation was found to improve survival in fish challenged with the fungus, with higher transcript abundance of Il-17 being associated with greater survival. This highlights the important role of pro-inflammatory cytokines in response to fungal infections.

Summary: Methylparaben (MeP), commonly used in daily products as a preservative, has become a concerning aquatic pollutant. This study exposed adult zebrafish to different concentrations of MeP to investigate its reproductive toxicity. The results showed that MeP exposure affected gonad development, disrupted hormone balance, and led to developmental deficits in offspring. This study provides insight into the antiestrogenic activity and reproductive toxicity of MeP.

Summary: In this study, microbroth kinetic protocols were established to analyze the growth of Veronaea botryosa, a dematiaceous mold causing systemic phaeohyphomycosis. The study also tested the susceptibility of V. botryosa isolates to natamycin, a macrolide polyene antifungal agent. The results provide important information about the growth and susceptibility of V. botryosa, which can contribute to future therapeutic protocols against emerging fungal diseases.

Summary: This study aimed to characterize trypsin from beluga and sevruga sturgeon species, focusing on their physicochemical and biochemical properties. The results showed that the trypsin from both species had similar characteristics to trypsin found in bony fish, indicating its potential use for assessing protein digestibility in these primitive species.

Summary: Differences in individual personality are common among animals and play an important role in ecology and evolution. This study focused on Siberian Sturgeon and found that shy individuals had better swimming performance, higher recovery ability after exercise fatigue, and streamlined morphological features. These findings contribute to the understanding of fish behavior biology and highlight the relationship between personality and swimming performance.

Summary: The morphological, histochemical and ultrastructural aspects of ovarian development in three phenotypes of Macrobrachium amazonicum were analyzed. Despite the morphological differences and different reproductive strategies adopted by the females, the patterns of ovarian development showed no differences between the phenotypes.

Summary: The reproductive activity of captive dusky groupers was evaluated using non-lethal tools. The plasma profile of gonadal steroids and follicle-stimulating hormone (FSH) was measured, and the effects of human Chorionic Gonadotropin (hCG) and 17 beta-estradiol (E2) implants on vitellogenesis were investigated. Results showed that captivity had a negative impact on vitellogenesis in E. marginatus.
