Restraint of unsedated fish for non-lethal biopsies

    This oscar Astronotus ocellatus is being gently held in a wet, gloved hand for skin mucus collection and fin biopsy. A gill biopsy can also be performed, but the fish should be returned to water for a brief period (30 seconds to one minute) before performing another procedure.
