Abstract

<jats:p>The brown shrimp,<jats:italic>Crangon hakodatei</jats:italic>Rathbun, 1902, is a common species in northwestern Pacific waters. Based on an investigation of references since the 1950s, we studied the ecological features of this commercially important shrimp. The results show, that the species has a long reproductive period with ovigerous females throughout the year and two discrete peaks in the spawning season, i.e., in spring and in autumn. Its sex ratio also shows significant seasonal variation. This shrimp is a keystone species in the demersal trophic pathways in the northern Chinese seas. It occupies an intermediate position in the food web, acting both as an important food resource for flatfishes on a higher trophic level, and as a predator upon the early life stages of those flatfishes.</jats:p>
