Where are all the native Californian trout, all 10 of them?

They must be endangered then ?????

[Fario]

There can be only one! That counts, anyway.

YE!! The native part got stuck with you.

You are quite correct Mario, they are all endangered! Check this out

Coastal Cutthroat Trout - Oncorhynchus clarki clarki (species of special concern)

Stealhead Trout - Onchorhynchus mykiss irideus (endangered / threatened)

Kern River Rainbow Trout - Onchorhynchus mykiss gilberti (species of special concern)

Little Kern Golden Trout - Onchorhynchus mykiss whitei (threatened)

California Golden Trout - Onchorhynchus mykiss aguabonita (candidate species positioned for listing)

Goose Lake Redband Trout - Onchorhynchus mykiss subspecies (species of special concern)

McCloud River Redband Trout - Onchorhynchus mykiss subspecies (species of special concern)

Eagle Lake Rainbow Trout - Onchorhynchus mykiss aquilarem (species of special concern)

Lahontan Cutthroat Trout - Onchorhynchus clarki henshawi (threatened)

Paiute Cutthroat Trout - Onchorhynchus clarki seleniris (threatened)

From Wikipedia:

• Genus Salmo
  
  • Adriatic trout, Salmo obtusirostris
  • Brown trout, Salmo trutta
  • Flathead trout, Salmo platycephalus

• Genus Oncorhynchus
  
  • Apache trout, Oncorhynchus apache
  • Eskimo trout, Oncorhynchus inupiat[verification needed]
  • Seema, Oncorhynchus masou
  • Cutthroat trout, Oncorhynchus clarki
    The cutthroat trout has 14 recognized subspecies (depending on your sources), such as the Lahontan cutthroat trout, Oncorhynchus clarki henshawi, Bonneville cutthroat trout, Oncorhynchus clarki utah, Colorado River cutthroat trout, Yellowstone cutthroat trout.
  • Gila trout, Oncorhynchus gilae
  • Golden trout, Oncorhynchus aguabonita
  • Rainbow trout, Oncorhynchus mykiss
  • Mexican Golden Trout, Oncorhynchus chrysogaster and as many as eight other species or sub-species in northwest Mexico, not yet formally named.

• Genus Salvelinus (Char)
  
  • Arctic char, Salvelinus alpinus
  • Aurora trout, Salvelinus fontinalis timagamiensis
  • Brook trout, Salvelinus fontinalis
  • Bull trout, Salvelinus confluentus

  • Lake trout, Salvelinus namaycush
  • Silver trout, † Salvelinus fontinalis agassizi (extinct)

Is this list complete?? Can anyone add what is left out (if) please.

I believe Marble trout from Slovenia isn't on your list. Unfortunately, I don't know the scientific name.

Salmo trutta marmoratus

Sorry Mario, I think you covered Marble trout already.

HI Guys,

I find this to be a very informative thread, brilliant posting.

Thanks

Specifically trout?
Or the salmanoid species? Isn't the Grayling a member of one these families?

grayling (species), Thymallus thymallus
grayling (genus), generically, any fish of genus Thymallus
Australian grayling, of the genus Prototroctes and family Retropinnidae

But yes, let's keep this thread on the noble fish only

[Ryan Weaver]

Checking the old records here at Jonkershoek:
Salmo Fario: 1875, 1884, 1892 planted into the Eerste, Lourens, Breede and Berg. Subsequently both S.irideus and S Fario widely distributed from the hatchery (as far afield as Rhodesia!)
O mykiss, which is still bread here now, 1896.
Not of interest: In their native streams these fish spawned at different times of the year whereas in our local SA rivers they spawn at the same time making hybridizing very likely. I'm almost certain we now have our own unique "strains".

Chris: Rainbow Trout, now O Mykiss, used to be under the Salmo genus. When was that changed and what was their previous naming?

HI Guys,

Would the triploid fall under rainbows? Being a no sex trout strain.
