All About Florida Keys Fishing & Key West Fishing
______________________________________________________________________________________________________________________
Crevalle jack are found throughout the Gulf of Mexico and southern US Atlantic coast
across a wide range of depths from shallow inshore to oceanic waters (Benson 1982). Except for
the development and ecology of juveniles, little is known about their life history (Berry 1959;
McBride 1995). Larvae and early juveniles are pelagic; they are found, occasionally in
association with jellyfish, in offshore waters. From April through November, juveniles a
adults inhabit estuaries that exhibit moderate to high salinities (Springer and Woodburn 1960).
Occasionally, adults occur in estuaries, but they are more often found on the continental shelf.
Crevalle jack reach about 7.9 inches fork length after one year (Table 1). Females appear to get
older and grow larger than males. The maximum age observed in Florida was 19 years (Snelson
1992). Few fish greater than age 5 have been collected from Florida. Females mature at age 5 or
6; males mature at age 4 or 5. Spawning apparently occurs during the period April–June.
