Fish larvae counts and standardized counts for eggs captured in CalCOFI ichthyoplankton nets (primarily vertical [Calvet or Pairovet], oblique [bongo or ring nets], and surface tows [Manta nets]). Surface tows are normally standardized to count per 1,000 m^3 strained. Oblique tows are normally standardized to count per 10 m^2 of surface sampled.
