That's what happens when the hormones get going. Spring is coming.
Diploid trout will produce eggs and sperm. The males tend to get colored up far greater and may even develop a kype.
Triploid females will not develop any eggs. Triploid males tend to color up and still follow some breeding behaviors even though no sperm are produced.
Spawning fish tend not to be ones that you want for the table....or even to catch as they often are poor fighters compared to clean fish.
