Date First Found

About Rainbow Smelt

Rainbow smelt is a very small (7 to 9 inches long, weighing 3 ounces) invasive fish. They are silvery overall with a pale green back and iridescent purple, blue and pink on their sides. They have a conspicuous silvery streak running lengthwise along each side. In the water, rainbow smelt shimmer colorfully. When removed from the water, however, they quickly fade to a silvery white and give off the odor of cucumbers.
