Light wavelengths and intensities affect the cortisol (stress hormone) levels in fish. Thus, this study aims to determine the optimum light wavelength and intensity to re-duce stress of juvenile sutchi catfish, Pangasianodon hypophthalmus. The sutchi cat-fish juveniles (35 days post hatching) were reared for 28 days (20 individuals/30 L) under five
