STANDARD LENGTH (mm.) 



-Body-depth ranges for T. falcatus, expressed as percent of standard length. (Five sites on the south Atlantic 

 coast of the United States and seven collecting dates are presented.) 



In Trachinotus sp. eye diameters of the 3. 07-, 

 4.0-, and 4.66-mm. specimens are 11.0, 13.2, and 

 11.2% S.L. (appendix table 2). 



BODY DEPTH 



Relative depth increases with an increase in 

 standard length to about 120 mm. in all species. 

 Growth patterns for T. carolinus and T. glaucus 

 are similar, with T. glaucus slightly the shallower 



between 20 and 120 mm. T. falcatus is markedly 

 deeper at all sizes. Below 10 mm., the relative 

 depth for T. carolinus and T. glaucus is about 

 32-36% S.L. and increases to about 48-50% S.L. 

 at 130 mm. Above 130 mm., this relative depth 

 is maintained in T. carolinus to about 200 mm. 

 after which it gradually decreases, with specimens 

 about 300 mm. and above having a depth ap- 

 proaching 40% S.L. Below 10 mm., T. falcatus
