Thank you Labugay Ako Yes this is an amazing act for the salmon. Once the babies emerge from the stones in a few months time,they will eventually go out to sea for two to three years and then come back to the same stream to spawn and die.And complete the cycle of like.
Thanks for sharing, Kevin. I thought they spawn in fall. I watched then in Lake Michigan and some of its tributaries and it's amazing how the manage! Do males ever participate in the redd construction? Do they guard their redd before they expire? Thanks
Hi paleozon thanks for the comment. Fall in New Zealand is in April/May so yes it's the same season but in the southern hemisphere. The female or "hen" does all the work.The male or "jack" does nothing other than chasing off other males if he is strong enough, similar to stags in rutting time. Once the male has finished mating he doesn't stay around and will go in search of other females. The female continues to cover over the whole spawning site with stones until she is exhausted and worn out then guards her redd until she expires. Regards Kevin.
It'd be a miracle if any of the second group survive considering the female literally used her tail right on all of them sending most of them down the river to get eaten/destroyed... It's amazing how these fish manage to reproduce with ones like that, that basically kill all of the freshly fertilized eggs.
She digs a nest using her tail in the stream bed,then covers it over with stones after laying the eggs.The male is only there to fertilize the eggs.Hope that answers your question Sarah..
The male or "jack" is the darker one with the hooked mouth and big teeth. The male changes to a darker colour and develops the hooked mouth once he has reached the spawning grounds. The hooked mouth and exposed teeth is to look "angry" and fight off other males who may try to compete for the right to mate with the female. The dominant male usually wins the right to mate with the female. The female or hen which is the lighter of the two fans her tail to dig a nest or redd in the stones for the eggs to be deposited. Once the eggs are laid and fertilized the hen then uses her tail to cover the eggs. The eggs will hatch in a few months time and the baby salmon or alevin will emerge from under the stones. I hope this answers your question Regards Kevin.

This is the first time am seeing the what we called spawning. Its so amazing!
Thank you Labugay Ako

Gotta love their O faces
The fact that the male is originally a hatchery fish is amazing
I just noticed when you mentioned it.
Magic, thanks
They really went: YOOOOOOOOOOO!!!!

Do males ever participate in the redd construction?
Do they guard their redd before they expire?
Thanks

@@KevinBelcher That definitely makes sense. I didn't realize it was in New Zealand.
Thanks for taking the time to respond, Kevin.

The survival rate is very low indeed, but that's nature.Maybe less than 0.1% will survive and return at best.Thanks for the comment Richard.
What is that momma fish doing that for?
She digs a nest using her tail in the stream bed,then covers it over with stones after laying the eggs.The male is only there to fertilize the eggs.Hope that answers your question Sarah..
was this recorded during a post-subdominant run because only the male and female are on screen?
Due to low returns which is unfortunate, these two had the spawning site to themselves.
i hear there is a species of salmon with homosexual salmon in their population
What she or he doing with his tail and wich mAle or female

I'm COOOOMING
why do they open their mouths
Don't really know.Maybe it is to get as much oxygenated water through the gills during the process of laying eggs or ejecting milt.
Can you grab the eggs and raise them at home to release in your local creek?
No not really possible and the Fish and Game Regulations do not permit such activity.
It's best to leave them for nature to run it's course.
@@KevinBelcher ok thanks
