Walleye Freshwater Perciform Fish
 Native to most of Canada and to the northern United States, the Walleye is a freshwater perciform fish. The fish is a next of kin to the European pikeperch. It is also called the yellow walleye in order to distinguish it from the vanished blue walleye and come from the family Esocidae.
Hereditarily these Walleye show variation across watersheds. Generally, within a watershed fishes are quite similar and are hereditarily different from those of nearby watersheds. The species has been spread for over a century. They have been placed on top of populations or are introduced into waters devoid of the species. Sometimes the overall genetic distinctiveness of populations has been reduced.
The name Walleye signifies that unlike the eyes of the cats, their eyes reflect light. It is from there that the name has been derived. This happens due to the light-gathering layer in the eyes, which is also called the tapetum lucidum. It allows the fish to visualize in low-light conditions too. Anglers search walleyes at night, as that is when the feeding patterns of the fish occur. They can also see well in muddy waters, which are an added advantage over to catch their prey.
This is why the Walleye anglers generally look for the exact days and locations when there is dirty and muddy water. The fish is often found in deeper water as their vision allows them to go into deeper lakes.
The Walleyes grow upto a height of 75 cm (30 in) and weighs about 7 kg (15 lb). As per records, the maximum size of the fish can be 107 cm (42 in) in length and weighs about 11.3 kg (25 lb). It depends on the area where the fish occurs as to how long they can grow. It is seen that the fishes belonging to the southern parts grows faster and larger. Generally, the females grow larger than males. Walleyes may live for decades; the maximum recorded of their age is 29 years. However in areas having heavy fish population, walleye older than 5 or 6 years of age are attacked.
The color of the fish Walleye is generally olive or gold. The borders of the fish are golden and the dorsal side is olive in color. The color of the body is intersected by the saddles that go up to the upper part of the body. The color of the belly is white. The mouth of the fish is large and contains sharp teeths. The Walleyes are differentiated from another similar species, the sauger, with the help of the white color present on the lower part of the caudal fin, which is not present in the sauger. The latter also contains marked rows of black dots, which are not seen on the Walleyes. Walleye
