Where does a blue catfish live?

A blue catfish lives in freshwater rivers. They are native to the rivers flowing through Mississippi, Ohio, Missouri, Virginia, and Maryland. They also reside in the Chesapeake Bay where they can be found in huge numbers. Their population in the Chesapeake Bay is so inflated that they pose a problem. They are also found in the York River, James River, and the Rappahannock River.

What is a blue catfish habitat?

The blue catfish resides in the depths of rapidly flowing rivers. They can also be found in channels. Their high adaptiveness for varied salinity levels, water conditions, and habitats makes them suitable for varied living conditions as well. As a rule of thumb, they seek currents with cool water in summers and warm currents in the colder seasons. During the daytime, their movements are restricted to the river -bed. On the other hand, their nocturnal nature helps them to swim to the surface for food during the night.

How do they reproduce?

The reproduction process of a blue catfish takes place once annually between the months of April and June. This mating process usually occurs in water bodies with a lower salt content than where the blue catfish usually lives. The venue is also generally a smaller tributary. Their annual reproduction process is monogamous in nature. The male blue catfish nest in dark and sheltered areas. They clean the nesting area by doing away with debris or larger items with their tails and jaws respectively. After building a nest of about 3-7 in (8-18 cm) radius, the male blue catfish attracts the female blue catfish by releasing pheromones. The couple then displays their courtship through patterns while swimming. After courting, reproduction occurs and the females reproduce 2000-4000 eggs. Unfortunately, it may be seen that after fertilization of the eggs the females are ousted from the nest by the males in an attempt to shelter the eggs. The baby blue catfish, after they hatch, form close-knit schools. The blue catfish follow a patriarchal structure when it comes to caring for their young ones.

What is their conservation status?

The population of the blue catfish is quite stable. Hence, they are listed by the International Union for Conservation of Nature (IUCN) as animals of Least Concern.
