What determines the color of Bluegill?

[Brian N.]

Hi, ive been wondering why bluegill or bass have different coloring, even when they are the same species. Ive been curious ever since i compare the coppernose in my pond to pics of other ppls coppernose. I think maybe what they eat is a factor but im no quit sure. If some one could elaborate on what deermines fish color it would be appreciated. P.s i googled to find out myself but found nothin!

Depth & water temp are some factors out here....

Now that makes sense, i knew about how during spawn they change colores especially the males, but i never thought about water clarity being a factor. Thankyou, Tony for clarifying that for me:-)

There are a few factors responsible for differing coloration among bluegills, but two common ones are water conditions (clarity), and nutrition. Fish from clear water will often be darker than fish from muddy or stained water. Also, bluegills may vary in color at different times of the year, most noticeable in males during the spawn. And, bluegills may also change their coloration in response to various stimuli, and this can be seen after catching a fish and placing it in a bucket....they will often change colors due to stress. This is accomplished by manipulating pigment containing cells known as chromatophores.
