Evaluation of growth, nutrient absorption, body composition and blood indices under dietary exposure of iron oxide nanoparticles in Common carp (Cyprinus carpio)

Journal of Animal Physiology and Animal Nutrition, Journal Year: 2023, Volume and Issue: 108(2), P. 366 - 373

Published: Nov. 5, 2023

Abstract The bioavailability, small size and direct absorption in the blood, make nanoparticles (NPs) a remarkable feed additive aquaculture industry. Therefore, dietary iron oxide (Fe 2 O 3 ‐NPs) were used to examine their effects on growth, nutrient absorption, body composition blood indices Cyprinus carpio (Common carp) fingerlings. Healthy C. fingerlings ( n = 270) fed with six canola meal based experimental diets (D1‐control, D2, D3, D4, D5, D6) supplemented 0, 10, 20, 30, 40 50 mg/kg Fe ‐NPs respectively. A total of 15 (average initial weight 5.51 ± 0.04 g/fish) kept triplicates for 70 days. results indicated that maximum growth performance, apparent digestibility coefficient, haematological parameters observed supplementation. All significantly improved p < 0.05) all above than control diet. In present research, recommended dosage as supplement is improving Hence, this study demonstrates potential NPs improve health fish.

Enhancing aquaculture disease resistance: Antimicrobial peptides and gene editing

Reviews in Aquaculture, Journal Year: 2023, Volume and Issue: 16(1), P. 433 - 451

Published: July 5, 2023

Abstract Previous studies have demonstrated that CRISPR/Cas9‐mediated genome editing and transgenesis by integrating vector‐engineered antimicrobial peptide genes (AMGs) are effective to modulate the fish's innate immune system. To generalise knowledge of AMG application in aquaculture, we recruited 544 data entries from a pool empirical studies, which included 23 (two unpublished our team) spanning 12 diseases. We systematically re‐processed re‐analysed these harnessing cross‐disease meta‐analysis. On aggregate, AMG‐genetic engineering aimed at enhancing disease resistance was shown decrease number colony‐forming units bacteria fish tissues, increase post‐infection survival rates, alter expression AMGs immune‐related genes. Further, pathogen‐combating activity triggered within 2 h after infection lasted 48 h. The overexpression highest spleen skin, followed kidney liver during this period. Typically, regardless type AMGs, synergistic with IL ‐ 10 , IKβ TGFβ C3b TLR AMG‐integrated contributed activating inflammatory/immune responses against pathogens. Our findings revealed efficiency transgenic pathogens fish‐, pathogen‐ AMG‐specific. Compared bacteria, were less inhibitory viruses parasites. In addition, innovative CRISPR/Cas9‐based enabling site‐directed knock‐in foreign multiple loci assessed for enhancement combination other favourable fish‐production traits, including fast growth, sterility enriched fatty‐acid content. Altogether, indicated as transgenes substantial promise system enhance resistance.

Comparative study on nutritional quality and volatile flavor compounds of muscle in Cyprinus carpio haematopterus under wild, traditional pond and in-pond raceway system culture

Aquaculture Reports, Journal Year: 2022, Volume and Issue: 25, P. 101194 - 101194

Published: June 3, 2022

This study compared the physical characteristics, nutritional components, mineral elements, and volatile matter of muscle Yellow River carp (Cyprinus carpio haematopterus) grown under traditional pond system (TPS), in-pond raceway (IPRS), wild (WYRC) to reveal differences in its quality aquaculture natural growth conditions. The results demonstrated a significantly lower water-loss rate both WYRC IPRS groups than that TPS group (P < 0.05), whereas cooked was higher 0.05). firmness, chewiness, gumminess relationships were order > TPS, significant 0.05) observed among groups. had fibre density crude fat content group, their protein collagen ranked there difference between EPA (C20: 5n-3) followed exhibited As Hg contents 8 5 times higher, respectively, those cultured group. hexanal, heptanal, octanal, butanal, other substances did not differ These suggest different conditions influence muscle.

Effects of dietary citric acid, lactic acid, and potassium sorbate mixture on growth performance and intestinal immunological parameters in common carp (Cyprinus carpio) juveniles

Journal of the World Aquaculture Society, Journal Year: 2025, Volume and Issue: 56(1)

Published: Feb. 1, 2025

Abstract Acidifiers serve as effective feed additives that enhance fish growth and welfare. This study investigates the effects of a mixture lactic acid, citric potassium sorbate (denoted OA, in 1:1:1 ratio) on common carp ( Cyprinus carpio ) for first time. A total 240 fish, each weighing approximately 18.5 grams, were randomly assigned to four treatment groups, consisting replicates containing 15 fish. The fed diets supplemented with varying levels OA: 0 g/kg (Control), 2.5 (A‐2.5), 5 (A‐5), 10 (A‐10) duration 56 days. Growth performance, calcium phosphorus vertebrae muscle, intestinal antioxidant status, bacterial populations, gene expressions, well immunological parameters skin mucus blood plasma analyzed at end experiment. results indicated significant p < 0.0001) increase abundance Lactobacillus sp.
