The use of fish meal/oil in carnivorous feeds remains a concern for the environmental sustainability aquaculture. In this study, we investigated impact an innovative diet designed to be cost‐effective and environmentally sustainable (i.e., 60% replacement meal by blend plant, yeast [ Saccharomyces cerevisiae ], krill feed ingredients) on growth, health, welfare gilthead seabream ( Sparus aurata ). Over 135‐day experiment, were fed either or commercial (control), various parameters evaluated, namely growth performance, levels physiological blood related stress, immunity, welfare, as well swimming activity, serving proxy energy expenditure. Results revealed that enhanced compared control diet. Hematological biochemical indicators did not highlight any impaired condition while higher Immunoglobulin M measured plasma diet, potentially suggesting enhancement humoral immunity. However, accelerometer tags data exhibited overall expenditure, which was consistent with greater prealbumin plasma. conclusion, metabolism might compensated diet’s content, may boost immunity hence help develop better adaptation rearing environment, including its viral bacterial load, ensuring growth. Longer term investigations, measurements additional parameters, are required validate these promising preliminary outcomes.

In order to deeply analyze the individual biological characteristics of unique fish in China, lay a solid foundation for effective protection its germplasm resources, and further enrich consolidate basic data system endemic world. According ethical norms fishing licenses, 5 samples Diptychus maculatus 3 Aspiorhynchus laticeps were collected from Tarim River Baicheng County 2023 2024. The morphological characteristics, age identification anatomical observation two fishes analyzed by classical methods. Both belong Cypriniformes, Cyprinidae, Schizothoracinae. D. has long body, conical head, lower mouth with pair whiskers. is slightly blunt arcuate, lateral line complete. A. long, flattened round abdomen, large head that at front. It also whiskers located corners mouth. Age materials: lapillus 6+, asteriscus vertebra anal scales opercular bone 5+, 7+, 7+. peritoneal wall black or brown tooth type was 3·4-4·3; external behavior gill rakers 8-13; internal 12-16. pharynx teeth lines, 2·3·5-5·3·2; 11-13; 15-18. are special species distributed system. Their evolutionary adaptation closely related uplift Qinghai-Tibet Plateau. This study provides important better understanding these endangered lays their resource conservation.

Smoltification is stressful for salmonids, and cortisol one of the central endocrine regulators seawater adaptation. It has been established that plays both mineralocorticoid glucocorticoid functions by MR GR, respectively, since aldosterone hormone absent. Recently, investigations have proposed 11-deoxycorticosterone (DOC) precursor might support effects, but this mechanism remains unclear. Hence, we assessed early effects DOC on rainbow trout pre-smolts, key smoltification stage, via metabolic transcriptomic approaches. Thirty-six juveniles (~120 g) were treated 3 h with (1 mg/kg) and/or (eplerenone) or (mifepristone) receptor antagonists (n = 6 each group). decreased plasma glucose pyruvate increased phosphate liver glycogen. also downregulated carbohydrate metabolism-related genes in liver. Finally, gill RNA-seq analysis presented 1660 differentially expressed transcripts versus vehicle, 1022 eplerenone + 3324 mifepristone DOC. The enrichment mainly revealed upregulation ion transmembrane transport metabolism downregulation stress innate immune responses. This suggests a significant role osmoregulation pre-smolts through receptors. could contribute to improving animal welfare monitoring during featuring novel potential biomarkers.

A cohort 203 healthy male geese was randomly selected slaughtered at 70 days age. Measurements were taken pH, growth parameters, body dimensions, post-slaughter traits. High-throughput sequencing on Illumina HiSeq X Ten platform facilitated gene resequencing SNP evaluation, GWAS employed detect key within quantitative loci (QTL) intervals. individuals yielded a total 2601.19 Gb genomic data, an average depth 10.89×. Through analysis, 30 SNPs identified. These identified multiple chromosomes, including chromosome 17 (chr: 23.57-23.68 Mb) 13 (chr13: 31.52-31.61 Mb). By annotating these SNPs, nine (including

This study aimed to explore the impact of acute acidification on antioxidant, metabolic performance, and liver histology juvenile yellowfin tuna. The experiment subjected tuna a pH gradient environment 8.1, 7.6, 7.1, 6.6 for 48 h. findings indicate that seawater 7.1 significantly impacts antioxidant systems in comparison control group. At there were observed increases glutathione reductase (GR), total capacity (T-AOC), lactate dehydrogenase (LDH), hexokinase (HK), pyruvate kinase (PK), sodium-potassium ATPase (Na+K+-ATP), calcium-magnesium (Ca2+Mg2+-ATP). Conversely, low-density lipoprotein cholesterol (LDL-C), high-density (HDL-C), triglycerides (TGs) not different across treatment groups. However, an increase transaminases at suggested potential damage, which was further supported by structural tissue degeneration hepatocyte vacuolation. In conclusion, under conditions stress, is decrease suppression levels tuna, leading oxidative damage. lays foundation in-depth understanding response mechanisms as well healthy farming broader context acidification.
