Fish Identification ????
Jeff White and I were discussing black and white crappie identification while out Sunday fishing. We caught several that were hard to identify. I usually count the dorsal fins. However, several fish looked like the first dorsal had two spikes (hard spine) on it. These were small fishes and not really any distinguishing body marks. I know that the whites have the same number of spikes on the dorsal and anal fins, where the blacks may or may not have the same count. I know that the white males “darken up” during the spawn whereas the black males do not change color. I often wonder if this is how they identify themselves during the spawn.
Another thing is the fact that I have caught both species in a known spawning area. I think this may be weather related, but I am not sure. I believe this may have caused some cross pollination ( kinda). Not sure about this. I ain’t ever seen fish, uh,,,you know what I mean here.. I don’t know crap about fish DNA.
Anyone ever experience this, and, if so, what is your take on it?
