Summary: In this study, alginate and chitosan were used to encapsulate Lactobacillus bulgaricus in Beluga using ionic gelation and internal emulsification methods. The encapsulated bacteria showed improved survival rates in simulated gastrointestinal conditions and resulted in significant improvements in hematological and immunological parameters. However, the encapsulation did not affect the growth indices of Beluga compared to non-encapsulated bacteria.

Summary: In this study, six different feeding regimes were tested, and it was found that the combination of AN + CHL + AB + MD had the best results in promoting the growth and survival rate of H. huso larvae. The group fed only MD had the worst results, potentially causing underdevelopment of the digestive system, lack of attractiveness, starvation, and empty digestive tracts in larvae. Different feeding regimes had significant effects on crude protein, crude fat, ash, and dry weight.

Summary: This study investigated the effects of adding poultry by-product to the diet on the growth, metabolic indices, and digestive enzymes of juvenile Huso huso. The results showed that replacing fishmeal with PBM could lead to lower growth rates and affect feed utilization efficiency, but within a certain range of replacement, it maintained digestibility.

Summary: The study evaluated the effects of two autochthonous probiotics on Huso huso fingerlings, showing positive impacts on growth performance, immune status, and intestinal morphology. While blood parameters showed no significant differences between groups, some immunological indices and intestinal villi height were influenced by probiotic levels. The optimal range of autochthonous probiotics for fingerlings was determined to be 2.5-2.61 x 10^7 CFU/g based on regression analysis.

Summary: Animal nutrition plays a crucial role in the treatment of many diseases, including heart failure. The study aimed to assess the impact of a diet enriched in unsaturated fatty acids on the metabolic profile of dogs with heart failure. Results showed no significant differences in clinical parameters between the two groups, but metabolomic changes were more pronounced over time, indicating both favorable and adverse effects of the enriched diet.

Summary: The antioxidant activity of Klunzinger's mullet muscle hydrolysates obtained through Bacillus licheniformis fermentation and enzymatic hydrolysis was determined, showing higher free radical scavenging activity and metal chelating ability. These hydrolysates also exhibited a reduction in oxidative stress biomarkers in rats and increased total antioxidant capacity while decreasing malondialdehyde, nitric oxide, and liver enzyme levels.

Summary: This study identifies the fish-derived chemical signal, bile salt 5 alpha-cyprinol sulfate (5 alpha-CPS), as the kairomone that induces morphological defensive structures in the invasive species Daphnia lumholtzi. Experiment results confirm that exposure to purified 5 alpha-CPS induces significantly elongated helmets and spines in D. lumholtzi. These findings reveal the evolutionary conservancy of the molecular mechanism behind inducible defenses in Daphnia species against fish and suggest the ecological relevance of 5 alpha-CPS in predator-prey communication between Daphnia and fish.

Summary: Cyanobacteria, especially microcystins, are a major concern due to their toxic secondary metabolites. It is unclear if the adaptation of Daphnia populations to toxic cyanobacteria reflects increased tolerance to microcystins or to other cyanobacterial metabolites. In this study, we compared the response of Daphnia to a toxic cyanobacterium and its microcystin-free mutant, and found that adaptation to cyanobacterial non-microcystin effects is possible in Daphnia populations. The molecular mechanisms of tolerance differ for microcystins and other non-microcystin effects.

Summary: The study investigated the impact of maltodextrin and combinations of trehalose or glycerol on the stability of freeze-dried pepsin from skipjack tuna stomach. The results showed that the addition of 5% trehalose and 10% maltodextrin yielded the powder with the highest relative pepsin activity. The powder exhibited good flowability, solubility, and could maintain proteolytic activity under different humidity conditions.

Summary: Mass developments of toxic cyanobacteria have increased due to global warming and eutrophication, impacting the abundance of herbivory species of Daphnia. The negative effects on Daphnia are attributed to cyanobacterial secondary metabolites, including hepatotoxic microcystins and protease inhibitors. Evidence of local adaptation of Daphnia to cyanobacteria is limited, and this study provides evidence of adaptive tolerance to protease inhibitor-producing cyanobacteria.

Summary: There is potential to increase sustainability in fishing and aquaculture by utilizing byproducts in enzymatic hydrolysis to produce protein hydrolysates for bioactive peptides. However, oxidative reactions during this process can affect the safety and bioactivity of the end product. Different byproducts require standardized hydrolysis procedures and testing methods. Controlling hydrolysis conditions and reducing oxidation are crucial for producing high-quality protein hydrolysates with various applications.

Summary: In aquatic systems, organisms like Daphnia use chemical cues to detect predators like Chaoborus. A previous study showed that food quantity affects the induction of neckteeth in Daphnia, with lower food concentrations leading to stronger induction. However, a new study found that weaker neckteeth induction at high food concentrations is due to increased bacterial degradation of the chemical cue, rather than simply a response to food availability.
