Abstract | Mysids were sampled seasonally from the intertidal zone of the beach to a depth of 61 m offshore along the mid-Oregon coast. The seven mysid species collected occurred in characteristic bathymetric zones, with members of different genera occupying overlapping zones while members of the same genus occupied largely different zones. The distribution of one mysid species, Archaeomysis grebnitzkii was examined in greater detail. Adult and juvenile A. grebnitzkii were found to occupy different zones. Juveniles occurred in the inner surf zone and beach in high densities while adult animals were normally found from the seaward edge of the surf zone to 30 m in much lower densities. The mean brood size of A. grebnitzkii was found to be 47.2, with larger brood sizes occurring in early spring and summer corresponding to larger body sizes of the breeding females. |
