The
crevalle jack is a prey item for various surface-feeding
carnivores, such as finfish (i.e. striped marlin,
Tetrapturus audax) and sea birds. |
|
|
| 2. |
The crevalle jack is capable of producing croaking
sounds by grinding its teeth together while releasing
gas from its air bladder. |
|
|
| 3. |
The Florida fishing record for the crevalle jack
is 23.1 kg (51 lbs). |
|
|
| 4. |
Schools
of crevalle jacks have been observed to corner and/or
corral smaller baitfish. Once contained, the jacks
will feed on the baitfish with great voraciousness.
Their surface feeding commotion may be seen from
a great distance - often appearing as boiling or
churning surface waters. |

The
crevalle jack is a relevantly unimportant commercial
fish species. Never the less, they are fished
commercially throughout the year in southwest
Florida, and in the spring, fall, and summer in
the Gulf of Mexico.
Crevalle
jacks are an important sport fish, and are exploited
throughout their range. They are the most common
large jack caught off the west coast of Florida.
