Fluorescence Detection of the Ornamental Fish Cardinal Tetra (Paracheirodon axelrodi) [PDF]
Photochemistry and Photobiology, 2009 AbstractThe fluorescence spectra of the tropical fish, Cardinal Tetra (Paracheirodon axelrodi), originating in the Amazon region of Brazil, were determined. These spectra were then treated using factor analysis, generating two contributing spectra and separating out the noise.
