Published by NOAA NMFS SWFSC Environmental Research Division | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 22, 2026 | Last Modified: 2016-05-24T00:00:00.000+00:00
Fish larvae counts and standardized counts for eggs captured in CalCOFI icthyoplankton 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 m3 strained. Oblique tows are normally standardized to count per 10 m2 of surface sampled. This table includes only tows where one or more larvae were captured for the species selected by the user, i.e., no "zero" tows. The "Larvae Counts" table includes all tows by species, i.e., both positive and negative tows.
