Gars


Live Alligator Gar Fish [Family Lepisosteidae]

These fish are considered "living fossils", as they have been around for over 100 million years, and have retained many primitive features. There are now 7 surviving species in two genera, and all but one are listed IUCN LC (Least Concern) - clearly a successful family of fish. All are fresh water fish that sometimes enter brackish waters but rarely wander into the salt sea. All Gars are native to North and Central America and the Caribbean region. These fish are totally unrelated to the European Garfish.

Gars don't have the overlapping scales of modern fish, their "Ganoid Scales" are interlocking plates of enamel coated bone, pretty much inpenytrable to predators. They themselves are fierce predators, usually by ambush, and have very toothy jaws. Like some other primitive fish, they can breath air.

All the Gars are considered edible, but their eggs are extremely toxic to humans.   Photo by ProjectManhattan distributed under license Creative Commons Attribution-ShareAlike v4.0 International.

Genus Atractosteus



Alligator Gar


Live Alligator Gar Fish [Atractosteus spatula]

The largest of the Gars, this one can grow to 10 feet (3 meters) and 350 pounds (160 kg). This fish is found in the river drainages as far north as Ohio, as far east as the Florida Panhandle, and along the Gulf of Mexico a small way into Mexico. Generally, it is caught wild, but is of interest for aquaculture as it is tolerant of water conditions, fast growing, disease resistant, and has a high meat yield. It is sold as meat in the Mississippi drainage region. IUCN Red List LC (Least Concern).

Cuban Gar


Live Cuban Gar Fish [Atractosteus tristoechus]

The Second largest of the Gars, this one can grow to 6.6 feet (2 meters) but are usually around 3.3 feet (1 meter). This fish is found only in lakes, rivers and estuaries of Western Cuba and Isla de la Juventud, just south of Cuba. It is subject to subsistence fisheries and IUCN Red List CR (Critically Endangered). Aquaculture is in the experimental stages and restocking is planned, but neither is far advanced. Do not catch or eat this fish.   Photo by Poleta33, distributed under license Creative Commons Attribution-ShareAlike v3.0 Unported.

Tropical Gar


Whole Tropical Gar Fish [Atractosteus tropicus]

This fish is found in lakes and rivers of both the Pacific and Gulf of Mexico drainages of southern Mexico and Central America. this one can grow to 49 inches (125 cm) and 6 pounds (2.9 kg), but are more commonly about 24 inches (60 cm).

Some references list the Tropical Gar as toxic to humans, but there is a recipe from Tabasco, Mexico that requires them and cooks them with chili, limes, and salt. Also I have seen mention that they are a significant food source in Guatemala, and Nicaragua reported landing 87 tonnes in 2011. It is certain, however, that their eggs, like those of all Gar, are highly toxic to humans.

Genus Lepisosteus



Spotted Gar


Live Spotted Gar Fish [Lepisosteus oculatus]

This Gar is native to lakes and rivers of North America from southern Ontario to the Gulf of Mexico, and from western Texas to the Florida Panhandle, with some isolated populations outside that area, including one at the southern tip of Florida. They can grow to almost 5 feet long and 9.7 pounds (4.4 kg), but are more commonly about 3-1/4 feet (100 cm). They are a commercial catch in the lower part of their range, but not in the Great Lakes region where they are high in mercury and other unhealthy substances from industrial pollution. IUCN Red List LC (Least Concern).   Photo by Usien, distributed under license Creative Commons Attribution v3.0 Unported.

Longnose Gar


Live Longnose Gar Fish [Lepisosteus osseus]

This Gar has a wide range, from southern Quebec through the Great Lakes region and the Mississippi and Missouri drainages to the Rio Grande river, and from New Jersey to central Florida. They can grow to almost 6.6 feet long (200 cm) and 50.3 pounds (22.8 kg), but are more commonly about 3-1/4 feet (100 cm). To humans, they are primarily a sports fish, but some people consider them to be a very good eating fish. IUCN Red List LC (Least Concern), but are a concern in some states due to overfishing.   Photo by Cephas, distributed under license Creative Commons Attribution-ShareAlike v3.0 Unported.

Shortnose Gar


Live Shortnose Gar Fish [Lepisosteus platostomus]

This Gar is found in the Mississippi, Missouri and Ohio river drainages south to the Gulf Coasts of Louisiana, Alabama, and a little into Texas. They can grow to 2.9 feet long (88 cm) and 5.7 pounds (2.6 kg), but are more commonly about 2 feet (61 cm). They are important to ecologies, but are not much used as a food fish. IUCN Red List LC (Least Concern), but are a concern in Montana and Ohio due to limited range.   Photo by AlejandroLinaresGarcia, distributed under license Creative Commons Attribution-ShareAlike v4.0 International.

Florida Gar


Live Florida Gar Fish [Lepisosteus platyrhincus ]

This Gar is found from the Savannah river, Georgia, down through peninsular Florida. They can grow to 4.3 feet long (132 cm) and 21 pounds (9.6 kg), but are more commonly about 2 feet (61 cm). Although edible, they are not a popular food fish. Like all Gars, their eggs are highly toxic to humans.
