Given the economic significance of Procambarus clarkii in freshwater aquaculture and lack microbial antioxidants diet research, this study aimed to investigate optimal supplementation level feeding duration diets. A series three experiments were conducted assess long-term effects different MA levels on crayfish evaluate palatability diets by observing behavior examining short-term high MA. Our results indicate that using 1.5% MAs markedly increased activities antioxidant enzymes (T-AOC, T-SOD, GSH-PX) decreased malondialdehyde (MDA) content hepatopancreas hemolymph, with showing significantly higher survival rates due better capacity after 24 h air exposure stress. Under condition feeding, appropriate addition can promote growth is 0.62–0.66%. The lower willingness food intake group may be main reason affecting their growth. Conversely, alleviated adverse associated reduced diet. inclusion for a period 21 d optimized growth, accompanied an improvement during transportation. This demonstrates supplemented (MAs) improve performance, capacity, resistance stress clarkii. These provide valuable insights into potential benefits aquaculture.

To evaluate the effects of inactivated Lactobacillus plantarum (LPM) on carnivorous fish, juvenile largemouth bass [initial body mass: (5.62±0.13) g] were fed five isonitrogenous and isoenergetic diets containing 0 (M0), 200 (M1), 400 (M2), 600 (M3), 800 (M4) mg/kg LPM for 8 weeks. The results showed that in terms growth, weight gain rate (WGR) specific growth (SGR) significant second-order polynomial trend with increasing supplementation. WGR SGR M3 group significantly increased by 14.18% 5.62%, respectively, compared M0 group. Significant linear second order trends observed feed conversion ratio (FCR), protein efficiency (PER) deposition (PDR) increase dietary LPM. FCR was reduced 8.9% M2 to In intestinal health, amylase, villi number, length width lipase activity, liver crude fat content Dietary supplementation abundance beneficial bacteria. antioxidant capacity, supplemental level, superoxide dismutase malondialdehyde serum liver, Cu/Zn-SOD, Keap-1 TGF-β1 mRNA expression levels trend, Nrf2 level a trend.

The dietary lipid level is closely associated with ovarian maturation of broodstock. However, optimal requirements during broodstock gonad development for aquatic animals remain limited. In order to assess the impact levels (6%, 8%, 10%, 12%, and 14% lipid, denoted as L6%, L8%, L10%, L12%, L14%) on maturation, antioxidant status, messenger RNA (mRNA) expression genes involved in metabolism Macrobrachium rosenbergii (initial weight 10.53 ± 1.97 g), this study carried out an 8‐week feeding experiment. findings showed that while there was no significant difference survival rate across groups ( p > 0.05), gain observed prawns fed 8% lipid‐level diet significantly higher than those other diets < 0.05). hepatosomatic index gonadosomatic a increase rise More ovaries from M. reached stages Ⅲ Ⅳ after being supplemented between 14%.
