Abstract


This study evaluates the application of highly-diluted bioactive compounds (HDBC) as an alternative to improve the white shrimp Penaeus vannamei performance reared during a semi-intensive commercial-scale production cycle (130 days) in arid environmental conditions. The effects of HDBC were analyzed on productive performance, enzyme activity, and energy reserves associated with the nutritional condition. Six 10-ha earthen ponds were used. Two experimental HDBC treatments and one control treatment were evaluated: [T1 = PhA+SiT (phosphoric acid 7C and Silicea terra 7C); T2 = PaV+ViT (Passival® 7C and Vidatox® 31C); T3 = Control (No HDBC)], using 2 ponds × 3 treatments = 6 ponds. Three shrimp samples were taken (S1, S2, S3) at 7, 52, and 130 days. The results indicated that organisms from T2 significantly increased in several productive indicators, such as weight gain, daily weight gain, specific growth rate, total length, feed efficiency, and productive performance. T2's bioactive compounds ingested with the pelleted feed and present in the gut -even at highly diluted concentration- improved energetic reserves, such as lipids in the hepatopancreas and digestive enzyme activity, enhancing the physiological status of shrimp farmed under semi-intensive rearing conditions, suggest that HDBC used in this study could have a beneficial and eco-friendly impact on commercial-scale shrimp production.
