Great barracuda (Sphyraena barracuda) fish species information

Scientific Name
Sphyraena barracuda

Common Name
Great barracuda

Biology
Found predominantly at or near the surface (Ref. 6949, 48637). Juvenile occurs among mangroves, estuaries and shallow sheltered inner reef areas; adult occurs in a wide range of habitats from murky inner harbors to open seas. Diurnal and solitary, but can also be found in small aggregations. Feeds on fishes, cephalopods and sometimes on shrimps (Ref. 9626, 48637). Sold fresh. Utilized also dried or salted (Ref. 9987). Although this species is ciguatoxic elsewhere throughout its range, it has not been reported to be poisonous in the eastern Atlantic (Ref. 6949, 48637). Rarely attacks humans, usually with one quick, fierce strike, which, although serious, is rarely fatal. The world's record on hook and line is a 5.5-ft. fish taken in the Bahamas that weighed 103 lbs. (Ref. 13442).
