Buffalo Fish Distribution, Population, and Habitat

Distribution

Buffalo fish are native to North America, and they are distributed throughout Canada, Mexico, and Guatemala. Some species of Buffalo fish are found in larger regions, while others stick to a smaller geographical area. Each of the five species in the Ictiobus genus has its own geographical distribution, but they are all primarily from parts of Northern America from river basins or the Mississippi river.

Population

The Buffalo fish population is extensive throughout Northern America, and their population numbers are stable and have no cause for concern according to the IUCN red list. However, there are certain fish laws and regulations in some areas when it comes to Buffalo fish.

Habitat

The Buffalo fish lives in freshwater rivers, lakes, ponds, and creeks throughout North America. They live in shallow, sluggish waters where they swim at the bottom of the body of water, foraging through the muddy substrate and vegetation for food. Buffalo fish prefer to live in waters that contain a lot of vegetation because this is where they lay their eggs. The waters they inhabit are usually murky and contain mud as the main substrate.

Buffalo Fish Predators and Prey

Buffalo fish fall prey to larger fish, especially when they are juveniles. Since the Buffalo fish gets quite large and hide among dense vegetation, they usually stay out of predators’ way. One of the Buffalo fish’s main predators as adults is humans because they are a popular angler fish. The Buffalo fish’s low predator list may also be a contributing factor to how they can live for so long. Buffalo fish naturally prey on plankton, detritus, algae, insect larvae, small crustaceans, and other aquatic vegetation, making them omnivores.

Buffalo Fish in Fishing and Cooking

Fishing

Buffalo fishes were originally thought to be terrible gamefish because they were difficult to catch by a hook and line. Legal changes in 2010 have made Buffalo fish a target for bow fishing, which is why certain laws and fishing regulations were enacted in certain places. Buffalo fish are now considered to be a popular game fish and are great for fly-fishermen because they put up a fight. They can be caught with a fly rod and barbed hooks.

Cooking

Buffalo fish are considered to have a delicious taste with soft and juicy flesh in comparison to other fish like mackerel. Due to their reduced numbers since becoming a target for fishing, the Buffalo fish are not commonly caught to be eaten. They can be eaten raw or cooked, but they do contain a lot of bones that consumers should be cautious about when eating fish.

Buffalo Fish Reproduction and Lifespan

The Bigmouth Buffalo fish has been recorded to live up to 112 years, according to the measurement of their otolith ear bone by scientists. The Buffalo fish can live as short as 18 years of age, but the average lifespan reaches around 25 years. In captivity, the smallmouth buffalo fish only lives between 8 to 10 years, mainly because their environment is not as adequate as their large natural rivers and lakes that allow them to reach their full adult size.

Buffalo fish reproduce in waters that contain plenty of vegetation for their eggs to hatch and be hidden from predators. They travel upstream to reproduce and will usually migrate for this to be possible. Most Buffalo fish will travel in large groups to breeding grounds, where the females will release eggs and the males will fertilize them during spawning.
