In recirculating aquaculture systems (RAS), the impact of dissolved oxygen (DO) fluctuations on turbot is still not fully understood. This study investigated these impacts by selecting 135 (average dry weight: 6.0 ± 0.5 g) and exposing them to three DO levels: hypoxia (4.0 mg/L), normoxia (7.5 hyperoxia (23.5 mg/L). These groups were labeled as LF (low oxygen), NF (normal HF (high oxygen). The aimed explore adaptive mechanisms under hypoxic hyperoxic conditions, using microbiome, transcriptome, hematological analyses over a 40-day period. results suggest that significantly enhances growth without compromising composition intestinal whereas markedly impairs induces alterations in microbiome. Transcriptomic analysis revealed various pathways implicated adaptation both encompassing amino acid metabolism, protein lipid carbohydrate PPAR signaling pathway, etc. However, pathway changes are completely consistent. For instance, pancreatic secretion crucial for adaptation, while HIF1α plays key role tissue repair. Furthermore, genes ATP6 , HIF1 HSP90 CYP450 exhibited high expression levels during hypoxia, Hbae5 Man-SL showed elevated hyperoxia. indicators, there ways help adapt hyperoxia, including increased red blood cell (RBC) hemoglobin (HGB) counts; gas ion balance; urea nitrogen (BUN) malondialdehyde (MDA); polyphenol oxidase (PPO) lysozyme (LZM) activity. Although have extended exposure detrimentally affects growth, facilitates it. findings provide significant insights into response fluctuating levels.

A 50-day feeding trial was conducted to evaluate the effects of dietary supplementation with different levels compound lactic acid bacteria on growth performance, antioxidant capacity, intestinal microbiota composition, and immunity Strongylocentrotus intermedius . In this study, S. an initial body weight 26.47 ± 0.27 g used as experimental subject. Based (containing 56.15% Lentilactobacillus 20.59% Acetobacter ) at levels, subjects were categorized into four groups: 0% (RC), 0.5% (RL), 1% (RM), 2% (RH). The significantly improved performance in RL, RM, RH groups, including final (FBW), gain rate (WGR), specific (SGR), gonadosomatic index (GSI). Furthermore, immune indicators such total capacity (T-AOC), superoxide dismutase (SOD), catalase (CAT), phosphatase (ACP), alkaline (AKP), lysozyme (LZM) enhanced. Notably, digestive enzyme activities intestine reduced feed conversion ratio (FCR). Supplementation Arcobacter Vibrio colonization tract enhanced expression genes related antioxidant, stress, responses RM groups. Overall, diet non-specific ability, microbial stability
