Near infrared molecular assays can be used to detect small quantities of a molecule of interest in vivo or in vitro using laser dyes. A hand-held portable device is provided which can rapidly read small quantities of selected molecular tags in tissues of fish or other animals in the field. The device is composed of four components:

Foreign proteins are placed into the blood of an animal so that they can be recovered at a later time and used for identification. Proteins are administered to the animal from a water bath via the animal's gills (where appropriate), gut and, through the skin. The foreign protein is detectable in small amounts using immune assays which magnify the available signals or tags in an assay.
