Potency of Turmeric in Reducing Motile Aeromonas Septicaemia (Mas) in Pangasius hypopthalmus

Abstract

A study on the histological structure of kedney of Pangasius hypopthalmus that were fed with turmeric supplementation and were infected with Aeromonas hydrophila has been conducted in the Laboratory of Parasites and Fish Disease, the Fishery and Marine Science Faculty, Riau University from February to July 2019. There were 3 treatments applied. The first group (P1) was given diet supplemented by 0.5g of turmeric powder. The second group (P2) was given diet supplemented by 0.7g of turmeric powder. The third group (P3) was given diet supplemented of 0.9g of turmeric powder. After 14 days, the fishes were infected with Aeromonas hydrophila (0.1 ml of 109 of A. hydrophila culture). The negative control were fishes that were not receive any treatment, while the positive control were fishes that were infected with A. hydrophila, and were not given diet any supplementation of turmeric powder. Fishes were reared for 14 days and than kedney organ were obtained for histological study. Tissue sample were processed by standard histological method (formalin fixed, alcohol series, HE stained and 6 sliced). The result indicated that there were differences in the tissue of treated fishes and that of the control. Kidney tissue of the positive control shown badly damage, there were many necrotic spots, congestion, hyperplasia, hypertropy and haemorrhage. Kedney tissue of the treated fishes of P2 (0.7g of turmeric extract) shown less abnormalities such as necrotic spots and haemorrhage. It can be concluded that the turmeric supplementation in Fish feeding is able to cure A. hydrophila infection on fish.
