This paper describes a vinyl streamer tag for use on shrimp (Penaeus spp.). The tag is light and flexible, and has little if any effect on shrimp movement or behavior. In laboratory tests, the streamer was retained by the shrimp and caused no detectable tagging mortality, while considerable mortality occurred in shrimp tagged with a Petersen tag. In field tests over a 30-day period, there were limited dislocation and loss of streamer tags, but the dye used to color the vinyl material faded. Suggestions for modification of the streamer tag are made to alleviate these two problems. Mortality in shrimp tagged with the streamer did not differ significantly from that of untagged shrimp.
