STANOARD LENGTH CLASSES (mm) 



FIGURE 8.— Length- frequency distributions of thread herring larvae for 1971-74 cruises to the eastern Gulf of 

 Mexico. Frequencies are expressed as estimated abundance of larvae in each length class within the area 

 represented by the cruise. No adjustments for abundance have been made for cruises that did not cover the entire 

 area where thread herring larvae might occur.
