A Must-Read: Fishing Gifts For Men

In this short read, you will have an understanding of what are the primary differences of a male salmon to a female salmon.

Significance Between Male And Female Salmon

When trying to differentiate two salmons, it is quite challenging to tell this is mainly because of their subtle differences. You need to do some careful examinations to find those small variations in jaw shape and their head size.

Generally speaking, you can always tell them apart after you caught them and cut them open. It will be easier to tell if they begin their spawn season as male undergoes different changes.

Head To Body Ratio

Spawning can help in a bigger perspective to tell the difference between two salmons. As male changes, they become a bit larger from head to toe compared to female salmon. You can tell by their head as the male’s head becomes more elongated than the female’s head.

Head And Jaw Growth

As the male’s head becomes elongated, you can also notice that their jaws become even longer than their female counterparts. Male salmon develop a hook shape head, and as spawning season begins, they become more exaggerated.

They also develop strong and sharp teeth while the female becomes more smooth and modest.

Coloration

At first, if salmon has a pretty distinct silver color, as spawning time happens, the male salmon will eventually change its color to a more vibrant one. Their eyes turn bright red while the female counterpart turns green.

Some male salmon also show some more developed color patterns than female salmon.

Body Shape

When salmon were in the ocean, they have a similar body shape. Once they turn to the rivers to spawn, you can see that there are physical changes in their body shape.

The males become deeper while the females have a more slender body shape. But females can expand their belly so they can store their eggs.

Conclusion

Overall, salmon are pretty much the same only when they are about to spawn. Spawning is essential to their life cycle because they need to reproduce. It might not be as easy as it looks to differentiate as the season progresses.

But if you are an avid fan of fishing, you will find this more interesting and challenging to figure out their gender.
