Answer 1

The change in the color of the scales from blue to bright red in male salmon during mating season helps them stand out to attract a mate to reproduce. The bright red colorations in the scales indicate the male's health and genetic fitness, making them more attractive to potential mates. This helps ensure that the offspring have strong genes and increase the chance of survival.
