Abstract: (348 Views)
Quercetin is a flavonoid, abundantly present in plants and has gained considerable interest for its antioxidant properties. The present study was designed to assess and compare the influence of both free and nano-encapsulated quercetin on growth indices and survival in Penaeus vannamei. The ionic gelation method was used to prepare quercetin loaded nanoparticles (Qu-ChiNPs), and their characteristics were determined using DLS method. The finding related to the characterization of Qu-ChiNPs demonstrated that hydrodynamic size and Zeta potential were 160/1 nm and 33/8 mV, respectively, and in vitro release of drug from Qu ChiNPs illustrated burst release in the initial period. For feeding trial, shrimps with an average weight of 2/27 ± 0/18 g with 5 diets including: basic diet without Qu, Qu-Chi and Chitosan nanoparticles supplement (control), supplement with 0.5 g Querectin, 0.25 g Qu-Chi, 0.5 g Qu-Chi and 0.5 g Chitosan nanoparticles per kg of diet were fed. Shrimp were randomly divided into 5 groups, with 3 replicates in each group and 50 shrimp in each replicate. After a 2-month feeding period, results showed that final weight (Wf), weight gain (WG) and mean daily weight gain (ADG) of shrimp fed Qu-Chi 0.5 g were higher than the other treatments (P˂ 0.05). However, there was no significant difference in survival rate (SR) between treatments. The results showed that the use of Qu-Chi 0.5 g in the diet can have a positive effect on growth performance and survival of Penaeus vannamei.
