NOTE Tucker and Alshuth. Development of laboratory-reared Archosargus probatocephalus 
399 
Table 2 
Summary of proportional measurements of 145 reared sheepshead, Archosargus probatocephalus, larvae and juveniles. Except 
for body length, values are in percentage of head length (HL) or body length (BL). Mean ±standard deviation is on the first line, 
and range on the second. A zero means <0.5%. For BL, notochord length (NL) was used through flexion and standard length (SL) 
after flexion. DSpl = first dorsal spine, DRal = first dorsal ray, PvSpl = first pelvic spine, and Pv = pelvic fin.
