Editing Walleye (section)

==Description==
Walleyes are largely olive and gold in color (hence the French common name: ''doré''—golden). The dorsal side of a walleye is olive, grading into a golden hue on the flanks. The olive/gold pattern is broken up by five darker saddles that extend to the upper sides. The color shades to white on the belly. The mouth of a walleye is large and is armed with many sharp teeth. The first dorsal and anal fins are spinous, as is the [[Operculum (Fish)|operculum]]. Walleyes are distinguished from their close relative the [[sauger]] by the white coloration on the lower lobe of the caudal fin, which is absent on the sauger. In addition, the two dorsals and the caudal fin of the sauger are marked with distinctive rows of black dots which are absent from or indistinct on the same fins of walleyes.<ref>{{cite web|url=http://www.in-fisherman.com/content/world-walleyes|title=In-Fisherman - The World's Foremost Authority On Freshwater Fishing|website=In-Fisherman|access-date=24 March 2018}}</ref>

===Length and weight===
[[File:walleye weight length graph.jpg|right|thumb|287px|Weight and length of walleyes]]
Walleyes grow to about {{convert|80|cm|in|abbr=on}} in length, and weigh up to about {{convert|9|kg|lb|abbr=on}}. The maximum recorded size for the fish is {{convert|107|cm|in|abbr=on}} in length and {{convert|13|kg|lb}} in weight. The rate depends partly on where in their range they occur, with southern populations often growing faster and larger. In general, females grow larger than males. Walleyes may live for decades; the maximum recorded age is 29 years. In heavily fished populations, however, few walleye older than five or six years of age are encountered. In North America, where they are highly prized, their typical size when caught is on the order of {{convert|30|to|50|cm|in|abbr=on}}, substantially below their potential size.

As walleye grow longer, they increase in weight. The relationship between total length (''L'') and total weight (''W'') for nearly all species of fish can be expressed by an equation of the form

:<math>W = cL^b \,</math>

Invariably, ''b'' is close to 3.0 for all species, and ''c'' is a constant that varies among species. For walleye, ''b''&nbsp;=&nbsp;3.180 and ''c''&nbsp;=&nbsp;0.000228 (with units in inches and pounds) or ''b''&nbsp;=&nbsp;3.180 and ''c''&nbsp;=&nbsp;0.000005337 (with units in cm and kg).<ref>{{cite encyclopedia |last1=Anderson |first1=R.

This relationship suggests a {{convert|50|cm|in|abbr=on}} walleye will weigh about {{convert|1.5|kg|abbr=on}}, while a {{convert|60|cm|in|abbr=on}} walleye will likely weigh about {{convert|2.5|kg|abbr=on}}.
