Figure 3 
Length-frequency histograms of body length by total larval abundance in samples collected in the Gulf of 
Mexico during 2005-2007 with nets of 2 different mesh sizes (0.202 and 0.333 mm) for larvae of the 5 families 
targeted in this study: Engraulidae, Clupeidae, Scombridae, Sciaenidae, and Lutjanidae. Larval abundance 
was measured as the total number of larvae caught in a sample per the volume of water filtered during the 
tow multiplied by the maximum depth of the tow in meters and the factor 10 (total number of larvae under 10 
m 1 2 3 4 5 6 of sea surface). Only larval lengths up to 10 mm are displayed in this figure.
