Answer: Wels Catfish
The wels catfish, also called sheatfish or wels, is a large species of catfish native to wide areas of central, southern, and eastern Europe. They mostly reside in the basins of the Baltic, Black, and Caspian Seas.
It came to be found in the United Kingdom after being introduced to Western Europe as a prized sport fish. This freshwater fish is recognizable by its broad, flat head and wide mouth. Wels catfish are known to live for at least fifty years.
The wels relies largely on its hearing and smell for hunting its prey. Just like many other catfish, the species’ eyes are imbibed with a degree of sensitivity at night. That is when they are the most active. It has the ability to disorient its victim with its sharp pectoral fins. It then proceeds to suck its prey into its mouth and swallow it whole.
The female wels catfish can produce up to 30,000 eggs per kilogram of body weight. The role of the male fish is to stand guard until the brood hatches. It can take from three to ten days, depending on the water temperature for the hatching process to be completed.
If the water level decreases too much or too quickly, the male fish splashes the eggs with water with its tail in order to keep them wet.
