| Remarks | Samples were collected with double ring nets that were hauled vertically over the entire water column within 3-5 m of the seafloor to the surface, which had an average depth of 40-50m. Abundance of Pseudocalanus minutus was correlated with bottom salinity. Later-stage juveniles were more abundant in the Pseudocalanus minutus population (Ref 118525). | ||
