TL;DR: Automated analysis methods for the assessment of hematological parameters, as an alternative to manual methods, are a valid diagnostic aid for the future of aquaculture.

TL;DR: It is shown that a total replacement of fish meal with black soldier fly larvae meal in the diets of sea-water Atlantic salmon was possible without negative effects on growth performance, feed utilization, nutrient digestibility, liver traits or the sensory qualities of the fillet.

TL;DR: It was found that feeding black soldier flies increased diversity and altered the composition of gut bacteria of rainbow trout, which were further influenced by life-cycle stage and lipid content of the insect meal.

TL;DR: It is suggested that powdered ginger especially at 3% might augment some immunological and biochemical responses as well as expression of genes relevant to antioxidant and immune systems in zebrafish.

TL;DR: The present results confirmed that the oral administration of RLP has the potential to promote growth performance, enhance antioxidant and immunological parameters, and mitigate the negative effects of crowding stress on common carp fingerlings.

TL;DR: The result revealed that weight gain and specific growth rate were significantly increased in Channa argus and the effects of dietary flavonoids from Allium mongolicum Regel supplementation on growth, antioxidant and immune status, immune-related genes expression and disease resistance.

TL;DR: An automatic method for grading fish feeding intensity based on a convolutional neural network (CNN) and machine vision is proposed to evaluate fish appetite and shows that the grading accuracy reached 90%; thus, the model can be used to detect and evaluating fish appetite to guide production practices.

TL;DR: Results showed that growth performance, somatic indexes, hepatic and intestinal histomorphology, and the intestinal antioxidant and immunity indexes of fish were not affected by dietary treatments.

TL;DR: A rising prevalence of vibriosis in aquaculture, concomitant with the rapid development of this industry worldwide, is revealed in many Asian countries with tropical climate, limiting the progression in control and prevention aspects of the disease.

TL;DR: It was observed that the addition of ChNP at different levels significantly improved the growth performance, total feed intake, and feed utilization compared to the control group.

TL;DR: Investigation of the effects of dietary myrcene and menthol administration on common carp health in response to ammonia toxicity found effects seem to be related to the compounds antioxidant effects, which mitigated ammonia-induced tissue damage and anemia.

TL;DR: It is indicated that dietary LC and BA could significantly enhance antioxidant, fatty acids β-oxidation and immune ability, reduce inflammatory responses, it also had positive impacts on histopathological changes but could not improve growth performance and feed utilization of black seabream fed HFD.

TL;DR: The weight gain, specific growth rate, and protein efficiency ratio decreased with increasing dietary starch levels, and the effect of dietary carbohydrate level on the growth performance, body composition, plasma biochemical indices and antioxidant capacity of largemouth bass was investigated.

TL;DR: Cineole administration is beneficial for common carp as it suppresses stress response, augments thyroid hormones levels and suppresses oxidative stress, and cineole mitigates adverse effects of ammonia toxicity on serum T3 and suppress oxidative stress caused by ammonia toxicity.

TL;DR: In this review, the interest of phage biocontrol for aquaculture is discussed and how can bacterial resistance, ecological, pharmacological and production related issues be solved.

TL;DR: The current review summarizes and discusses the potential uses of fungal polysaccharides on growth performance, immune response and diseases resistance of various fish and shrimp species.

TL;DR: The introduction identifies five themes emerging from research on aquaculture value chains in the special issue of Aquaculture, namely: multi-polarity, diversity and scale, dynamics of transformation, performance and equity, and technical and institutional innovation.

TL;DR: It is confirmed that nutrient accessibility plays a significant role in the nutrient digestibility of the microalga Nannochloropsis gaditana in Nile tilapia and the in vitro methods used are effective ways to assess the effect of mechanical and physical treatments on in vivo nutrient quality of a single ingredient.

TL;DR: It is demonstrated that multi-probiotics had beneficial effects as an antibiotic replacer in terms of growth performance, non-specific immune responses and disease resistance in salmon.

TL;DR: Results indicated that high dietary lipid level inhibit weight gain and induce oxidative stress, which affect the health status of largemouth bass.

TL;DR: Investigation of the effects of dietary heat-killed Lactobacillus plantarum (HK L-137) on growth, digestive enzyme activity, intestinal morphology and oxidative status in genetically improved farmed tilapia finds that the HKL100 group had significantly higher growth rates than the control group.

TL;DR: Results indicated that combination of B. methylotrophicus and B. licheniformis produced significant changes in growth performance, immune response and disease resistance in rohu, Labeo rohita (Hamilton) fingerlings.

TL;DR: It was shown that a bacterial strain LPN080 isolated and screened from a shrimp culture pond can efficiently remove both ammonia nitrogen and nitrite and showed high biosafety toward shrimp Litopenaeus vannamei and has a potential economic value in aquaculture and even in wastewater treatment.

TL;DR: The outcome of the risk assessment indicated human health risks posed by MPs via seafood consumption from both cities is likely to be higher than those from Shanghai, UK and South Korea due to greater percentages of PAN contamination.

TL;DR: It is indicated that the most desirable fish diet substitution differentially affects the gut microbiota in different hosts, implying that a species-specific tailor-made approach in diet manipulations should be considered in the future.

TL;DR: Data suggest that B. velezensis AP193 can promote catfish growth and improve pond water quality when used as a feed amendment.

TL;DR: Comparisons were made among the bacterial communities in shrimp intestines and the related marine farm sediments that supported different growth performances, based on Miseq sequencing data of the V3-V4 region of 16S rRNA gene.

TL;DR: Assessment of the skin and gill microbiomes of two of the most important adult fish species farmed in southern Europe, the seabass and theseabream, during winter months coupled next-generation sequencing of the 16S rRNA V4 region with the DADA2 bioinformatic pipeline to assess microbial composition and structure found ASVs belonging to the genera Polaribacter and Vibrio were detected.

TL;DR: The results showed that the specific growth rate (SGR) and weight gain (WG) were significantly increased and the feed conversion ratio (FCR) was significantly decreased in the groups supplemented with 100, 150, 200 and 250 mg·kg−1 carotenoids.

TL;DR: It is demonstrated that nucleotides was a promising feed additives to enhance flesh quality in fish and had no effect on ash, calcium and phosphorus in fish fillets.
