Notable details

  • Adults typically reach 9 to 12 inches long and are a cornerstone prey species of the North Pacific.
  • Spawning females deposit sticky eggs directly onto kelp and eelgrass fronds in nearshore bays.
  • Mass spawning events turn the water milky white, drawing whales, seals, eagles, and diving birds.
  • Their roe, called kazunoko, is a prized delicacy in Japan and drives a major commercial fishery.
  • Form some of the largest fish schools on Earth, sometimes numbering in the billions.
