Counts are per net, with SWFSC's own effort (volume filtered, standard haul factor, proportion sorted). A tow with no egg, larva or invertebrate record is a true zero: it stays as a sample with its effort, and abundance rows are positive only. Counts of species codes that share a WoRMS AphiaID are summed per net; each code keeps its own name. A tow's and net's maximum depth is the maximum possible depth of the net (SWFSC NetDepth), not a measured depth: over a shallower sea floor the net did not reach it. Egg stages 12-15 are left out of the egg stage distribution. Fish grown past the larval stage are in their own table, fish. MOCNESS tows are not in the source.\n",
