Euphausia pacifica lives for a period of approximately one year,
disappearing from the catches at a size of about 22-24 mm. Spawning,
which occurs mainly inshore, extends from June through December
but generally is most prominent in the autumn months.
Average growth is calculated to be approximately 2.0 mm per
month or 0.06 mm per day, with growth appearing to be faster during
adolescent stages and somewhat slower during the older stages.
These growth rates are several times greater than previous estimates
for E. pacifica.
These studies were based on length measurements obtained
from monthly vertical meter net collections from stations off Newport,
Oregon over a four year period. / Graduation date: 1969
