Impact of Feeding Frequency on Growth Performance and Antioxidant Capacity of Litopenaeus vannamei in Recirculating Aquaculture Systems

Animals, Journal Year: 2025, Volume and Issue: 15(2), P. 192 - 192

Published: Jan. 13, 2025

Feeding frequency is crucial for the growth and development of white shrimp (Litopenaeus vannamei) at various life stages. Although higher feeding frequencies can enhance growth, manual methods significantly increase labor costs. Automatic systems offer a cost-effective efficient alternative, yet their application in intensive culture remains under-researched. This study evaluates different L. vannamei aquaculture tanks, focusing on performance, survivability, feed utilization, digestive antioxidant capacities, economic viability. Juvenile (3.85 ± 0.3 g) were cultured 63 days with 6, 8, 10, 12 times/day (A6, A8, A10, A12 groups, respectively) using automatic feeders, control group fed manually 6 (M6). Results indicated that improved final body weight, specific rate, conversion ratio compared to feeding. Among A6 A8 showed optimal quadratic regression identifying 7.83 as frequency. While enzyme activity remained consistent across demonstrated levels (superoxide dismutase (SOD) glutathione peroxidase (GPx)) lower lipid peroxidation (MDA), suggesting superior capacities. Pearson's correlation confirmed positive relationship between SOD GPx. Economically, achieved highest profitability. Consequently, 6-8 feeders recommended an feasible strategy this stage.

Abstract Aquaculture continues to expand swiftly and remains the fastest‐growing food industry worldwide amidst ever‐present threats from chronic stressors emerging diseases. Nutrition plays a pivotal role in profitability viability of aquaculture that steered paradigm shift therapeutic nutrition. Carotenoids, also termed tetraterpenoids, have garnered considerable attention owing their attributes immeasurable health benefits, which incited surge global demand. These biological pigments are recognized promote immune systems antioxidant defence mechanisms both aquatic vertebrates invertebrates. This review brings forth existing scientific evidence underscores notable roles carotenoids as biologically active constituents with anti‐stress immunostimulatory potentials farmed animals whilst explicating possible action. Empirical data unequivocally established modulatory functions on endogenous enzymes, innate adaptive arms response, well expression multiple immune‐related genes. The comprehensive information presented is beneficial deepen our understanding utilization potent stress alleviators immunostimulants cultured animals, translated into improved health.

The current study aimed to assess the influence of dietary inclusion cyanobacterium Arthrospira platensis NIOF17/003 as a dry material and free-lipid biomass (FL) on growth performance, body composition, redox status, immune responses, gene expression whiteleg shrimp, Litopenaeus vannamei postlarvae. L . were fed five different supplemented diets; first group was an un-supplemented diet negative control (C-N), second commercial with 2% A complete positive (C-P 20 ), whereas, three remaining groups graded amounts FL at 1%, 2%, 3% (FL 10 , 30 respectively). obtained results indicated that containing 1% significantly increased efficiency consumed feed, survival percentage compared both C-N C-P groups. As for carcass analysis, diets or its higher levels protein, lipid, ash content group. Moreover, shrimp gave stimulated digestive enzyme activities C-N. exhibited innate responses promoted their status profile. Also, low upregulated peroxiredoxin ( Prx ) prophenoloxidase PPO1 genes than those receiving recommended supplementation is most effective treatment in promoting performance immunity shrimp.

The study investigated the impact of chlorogenic acid (CGA) supplementation in a high-fat diet (HFD) on growth, lipid metabolism, intestinal and hepatic histology, as well gut microbiota spotted sea bass. A total 540 fish were fed six experimental diets, including normal fat (NFD), (HFD), HFD supplemented with 100, 200, 300, 400 mg/kg CGA (named HFD1, HFD2, HFD3, HFD4, respectively) for 7 weeks. results showed that feeding increased growth deposition compared to NFD group. Inclusion 300 decreased HFD-induced hyperlipemia (p < 0.05). Additionally, group, HFD4 group significant reductions serum aspartate transaminase (AST) alanine (ALT) levels malondialdehyde (MDA) content, while also improving liver antioxidant capacity (T-AOC) In CGA-containing groups, hepatocytes arranged more neatly than those there was reduction hemolysis liver.

Penaeus vannamei, a high-yield economical shrimp, is confronting germplasm degradation in the culture environments found China, which results sharp drop production. Genetic improvement by hybridization an effective way to solve this problem. In study, we selected hybrid species adapted low-salinity obtained intraspecific crossing as experimental group. The control group consisted of normal variety from Hainan Lutai Company. two groups shrimps were cultured for three months under salinities 1 PSU, 5 and 15 PSU. Growth-performance-related indicators, biochemical composition, molting-related gene expression examined. showed that at PSU survival rate growth performance low-salt breeding better than those population. digestive enzyme activity was higher, consistent with its performance, also associated higher triglyceride, total cholesterol, glycogen content. Lower levels lactic acid indicated less anaerobic metabolism adaptability environment. amino fatty acids analysis essential high unsaturated both shrimp genes molting (CHS, CaMKI, RXR, EcR, HSP60, HSP70) nutritional advantages compared This research provides valuable reference subsequent genetic culture.

Litopenaeus vannamei is a key economic species in aquaculture, yet the molecular mechanisms underlying its growth variability remain unclear. This study conducted transcriptomic and metabolomic analyses of fast-growing (NL) slow-growing (NS) shrimp under identical conditions. A total 1280 differentially expressed genes (DEGs) related to protein processing, ribosomes, oxidative phosphorylation, along with 5297 abundant metabolites (DMs) involved arginine biosynthesis, amino acid metabolism, pantothenate CoA were identified analyzed. An integrative analysis revealed that NL exhibited an enhanced retinol, glutathione, riboflavin, purine which implies higher tolerance environmental stress. In contrast, NS showed increased fatty degradation accelerated TCA cycle. suggests might require substantial amount energy cope changes, consequently resulting expenditures. provides significant insights into disparity L. vannamei, offering valuable data for future research aimed at optimizing performance enhancing aquaculture productivity.
