One of the detrimental impacts of the palm oil processing company that might disrupt aquatic environments is liquid waste. The purpose of this study is to characterize the biometric circumstances of the digestive system of thai mahseer, Tor tambroides (Bleeker, 1854) contaminated by palm oil mill effluent (POME). The study was conducted from July to October 2023. The fish sample size ranged from 7 to 10 cm in length and a weight of 15 g. For 30 days, fish were contaminated by POME at concentrations of 0% (control), 10% LC50 (A), 10% LC50 (B), and 10% LC50 (C). Analysis was carried out on the gastro-somatic index (GaSI), intestine somatic index (ISI), relative gut lengths (RGL), Relative Intestine Lengths (RIL), and hepato-somatic index (HSI). The research results show that POME can affect the biometrics of the digestive system of T. tambroides. Contamination to POME with a concentration of C (10% LC50) affects GaSI of 0.46±0.02%, ISI of 1.96±0.05%, HSI of 0.79±0.03%, RGL of 44.82±4.08%, and RIL of 139.95±8.25%. The POME can disrupt the metabolism of the stomach, intestine, and liver cells of T. tambroides. High concentrations of POME can damage the lining of the stomach and intestines, resulting in a decrease in appetite. © 2026, BIOFLUX SRL. All rights reserved.
