Effects of Lyophilized Açaí () Supplementation on Oxidative Damage and Intestinal Histology in Juvenile Shrimp Reared in Biofloc Systems.

October 2023
The objective of this was to evaluate the ability of bioflocs to assimilate and transfer antioxidant compounds present in açaí to juvenile shrimp grown in a biofloc system. Juvenile shrimp were distributed into four treatment groups (control, 5, 20, and 80 mg açaí L), containing 31 shrimps/tank (90 L), and cultivated for 30 days. Every 24 h throughout the experimental period, the respective açaí concentrations were added directly to the cultivation water.

The effects of silver nano/microparticles (AgP) on juvenile Litopenaeus vannamei shrimp were evaluated through several responses, aiming to use it as a prophylactic and therapeutic method. Shrimps (3.19 ± 0.

- Saxitoxin (STX) is a neurotoxic cyanotoxin that induces oxidative stress and metabolic changes, prompting a study on the protective effects of açaí fruit (Euterpe oleracea) against its toxicity in shrimp (Litopenaeus vannamei).
- Shrimps were fed a diet supplemented with lyophilized açaí for 30 days before being exposed to STX; molecular docking indicated that STX variants can interact with a specific enzyme (mu isoform of GST) crucial for detoxification.
- Results showed that while açaí supplementation reduced some toxic effects (like malondialdehyde levels in shrimp hepatopancreas), it also had
This study evaluated the effect of dietary inclusion of lyophilized açaí Euterpe oleracea (LEO) on redox status of shrimp Litopenaeus vannamei (initial weight 1.5 ± 0.39 g) upon exposure to cyanotoxin nodularin (NOD) in bioflocs system.
