The large mouth bass is an aggressive freshwater predatory fish in the Centrarchida family, a fish which is normally native to western and central North America, Canada, USA and Mexico, but also commonly found elsewhere in the world. It’s known for being an effective predator of many different types of fish, both live and dead, including other smaller freshwater bass, pan fish, striped bass, bluegill and silver carp.
This small fish is found in shallow waters that are frequently muddy or have poor oxygenating conditions. They prefer to feed on smaller sized fish, particularly minnows, cichlids, rosy reds, other catfish eggs and tadpoles, small crustaceans, and frogs. It may also feed on crayfish and other crustaceans, especially after a night feeding.
Common Sizes Of Mouth
Common sizes of mouth bass include around thirty to fifty millimeters, with specimens weighing up to two hundred and fifty grams. Their heads tend to be rounded and flat when they are still alive, with many species having two widely spaced, pointed dorsal fins.
The life cycle of the mouth bass can be quite long, even up to five years, but the lifespan is much shorter in freshwater as compared to saltwater. Their growth rate is much slower, with growth being rapid at about one centimeter per day and reaching a maximum of a metre in length. They are oviparous, which means they lay their eggs in water. They hatch within a day and the fry grows into adults in ten days.
Big Mouth Bass
The big mouth bass is often confused with some of the larger types of bass such as the bluegill and the rainbow trout. They are also often referred to as the common bass because of their widespread distribution in lakes and rivers throughout the country, but their diet and distribution are very different.
The largemouth bass is omnivorous and feeds both live and dead, although not exclusively on meat. Their diet is highly variable, depending on the type of fish they are feeding on, and they can be carnivores to semi-prey eaters, depending on the size of the fish they are targeting. They are also omnivores and can eat plants, worms, algae, insects, plankton, and even smaller fishes, although they are not often seen to feed on these.
Unlike many other freshwater fish, the largemouth bass has no natural predators, such as other fish or birds, so it will not eat other small aquatic organisms. and will eat other fishes from the surface of its lake or stream as well as from below, including plants.
Small fry are quite slow growing and are usually kept as pets as they are very hardy and able to cope with a wide range of aquarium conditions. They do however need a lot of space, so if you are planning to keep more than one, they are not recommended for an aquarium of less than half a metre depth as they are more active at night.
The life expectancy of the large mouth bass is estimated at thirty years old, but some specimens may live up to four decades. They are more prone to disease in captive fish and need constant care and vigilance.
The feeding habits of the large mouth bass are rather unique. Their main food is the minnow, a tiny fish that is found in fresh water. This is a good source of protein and it helps the fish to gain a balanced diet, especially if you plan to introduce a carnivores into your aquarium. The small mouth bass will also eat small crustaceans, worms and insects.
Although it is omnivorous, it will not eat plant matter and will feed on other fish as well as fish. The small mouth bass will also eat live bait and will even feed on other fish. if they get bored they will eat plants. They will eat just about anything but, they are not particularly picky about what they eat, but prefer to eat live prey.
When you purchase your small mouth bass from a local fish shop, they should give you information about the diet and food they are feeding. If you buy from online sources, it is worth contacting the company for advice.
