pascal, you are channa expert. I have some question.tigerlover2006;1479943;1479943 said:Thats a really long list of snake head you have!
what is the differrent between 'channa gachua' from krabi / koh chang / khao lak and central Thailand? Because all of these, I think I ID in the same name is 'channa limbata'
Pls explain.
And channa striata "Ubon Ratchathani / Thailand"
I understand that all of striata in Thailand is the same, nothing diff. from other province?
Thanks.
Hi,Oleoleole.....
That is a really good question!
First of all: you are maybe right!
But:
It is a long story to explain and I hope my english is good enough to do that...so I will try!
At the moment the Genus of Channa is not completely classified!
And exspecially the species complex around Channa gachua is very complicated,becuase they all look similar !
I have kept a lot of difference Channa gachua and there were allways differences between them.
Now,Praycha Musikasinthorn finds out ,that the number of scales on the jaw of the gachuas caught in Thailand are different to the gachuas of India.........and he decided to call them Channa limbatus ,which is not offical yet,but he will .........
And that is good,because they are different.
Ch. limbatus is at the time a Synonym for ch.gachua..........
I work togehter with Dr. Lukas Rueber and Dr. Ralf Britz who work on a genetic Analysis of the snakeheads familiy........
Musikasinthorn did this also,but he only works with mitochondrial DNA and Britz/Rueber worked wih base DNA..........
So the work Of Britz and Rueber is better thasn the work of Musikasinthorn!#
To be honest.........nobody nows exactly,if all of the limbatus in Thailand arethe same species........and that is why I classify them after their habitat.
I think until all the work is done it is the best way,because everybody knows werethey are from.......
The gacua/limbatus from Krabi for example have a bigger red band on the Dorsal fins and the basis colour of the body is more black/blue.........
The gachua from Koh Chang has a different base colour and they do not grow as big as the Krabi ones
The one I had got from Khao Lak have a huge head more frog like as the head of the Koh Chang and Krabi ones.......
Also the colour of the juveniles is different to each other........
I cannot explain in english ,exactly the way I want to explain (German would be better.......) but I hope you understand.
I think we will have a better result when Britz/Rueber have finished their genetic analysis....
I hate it that everybody is saying: Ohhh.ist is only a gachua!
Because it is not......
The gachua from Myanmar I have got at home are showin a completly different behaviour and colouration.......
The gachua from Laos is more similar to the Myanmar ones but there is Thailand betwenn this 2 Countries...........so ...how can this be???
The gachua from India have a red stripe under the eye....also the ones from Sri Lanka which is an Island!
The juveniles of the indian ones have an Occellus in their dorsal fin....the Thailand gachua have not!
So there are ,for my opinion a lot of difference between them.........
And the genetic Analysis has shown ,that the gachua from Inid are not relatives of the limbatus-gachua from Thailand!
We do not know anything about the poulations of Bali,Sumtra,Borneo Vietnam,Kambodscha......so ther will be al lot of suprises still!
But we have not enough samples from there.......and the most scientists have no time to care about all the gachua-limbatis species!
But I think it is a big group...not only a single species..........an to differentiate between them...I use the habitats.........for naming them!
Also it is the same thing with striata,marulia.........I think it isa group..not only a single species!
Let us wait for the results of the genetic analysis..then wewill know more!!!
Sorry for my english..........but it is not good enough for this complexitiy to explain!
Cheers

Pascal, my English isn't so good too but I understand the thing that you explain.
Actually, when I saw gachua in Thailand, I call "Pla Kung" but I think it maybe diff. only color depend on which place that it caught. Because it not diff exactly like marulius (Mekong, Me-klong, Salween, Ta-pee) and marulioides (Thailand, Malysia).
I think gachua from Laos & Myanmar are sililar because Mekong, Salween and Irawadi rivers are so close, not like the river in Thailand, maybe.
And How do you bring it to Germany?
Thank you for your information.

i'm also wanna know if my c.gachuas from peninsular malaysia and from sarawak borneo is different? because the color a bit different.
Hi,Guys........
Ohhh.....sometimes it is soo difficult to write in english!
Hmmm........maybe it is only one kind of gachua/limbatus in thailand.........maybe not!
When there are regions with mountains.........how shall the fish come to there,if the riveres have no connection?
What about populations,living on Islands???
We will see what the genetic research will Bring!
@ Na Cheers........
You have send me a pm !
I will answer it as soon as I can.have a lot to do at the moment!
I will send you the pictures of the fish you would like to see!
Otherwise:..........
gachua from your country is hard to get here in europe.........we have no samples of them!
Als gachuas from other indonesian parts........no samples at the moment!
