Abstract: Paralarvae of the commercially important squid Ommastrephes
bartramii are described, and particular attention is paid to the chromatophore
patterns. These chromatophore patterns are compared with those of Stenot euthis
oualaniensis and Hyaloteuthis pelagica , two other local ommastrephids with
similar patterns. Limited data on spatial and temporal distributions of the
paralarvae are also presented. Paralarvae of O. bartramii have been found at
several localities along the Hawaiian Archipelago between Oahu and Midway
Islands. In 1986 O. bartramii probably spawned in southern Hawaiian waters
around the island of Oahu from, at least, the latter part of February through
March. During April 1979 and April 1984 the absence of paralarvae from these
same waters suggests that either the spawning period terminated earlier or the
squid did not spawn as far south as in 1986. High abundances of O. bartramii
paralarvae in some April 1979 samples suggest that spawning was more intense
in the northwestern half of the Hawaiian Archipelago.
