الوصف
During their ocean phase, coho salmon have silver sides and dark-blue backs. During their spawning phase, their jaws and teeth become hooked. After entering fresh water, they develop bright-red sides, bluish-green heads and backs, dark bellies and dark spots on their backs. Sexually maturing fish develop a light-pink or rose shading along the belly, and the males may show a slight arching of the back. Mature adults have a pronounced red skin color with darker backs and average 28 بوصة (71 cم) andسبعة to 11 رطلs (3.2 to 5.0 kغ), occasionally reaching up to 36 رطلs (16 kغ). Mature females may be darker than males, with both showing a pronounced hook on the nose.
