The Mystus ID Thread

[Shane]

I wish I knew why the Indian and wild Far East shipments have dried up around here. Five months of haunting the local shops and I have come across only a single Mystus mysticetus which was sold back to a shop by an aquarist. Where have all the bagrids gone?

I think this is in the hands of the importers at the moment. I know for a fact that there are many bagrid catfish (in addition to others) waiting to be shipped out of here but not many interested in importing the same.

Aren't there some in Aquabid?

[Shane]

Yes, but next day air shipping from Oregon to Virginia is not cheap (over $400 per the UPS site). I may eventually have to give it a try.

Pics : Ashwin

Specimen (around 6" TL) from Karnataka. I initially thought Mystus seengtee looking at the spot at the base of the dorsal fin and size of the adipose. I received this specimen yesterday and I am not too sure now. It has turned completely black. My friend who kept this specimen briefly also experienced the same. It is still under a great deal of stress from the travel. I will take some pictures in a few days time. I have received Mystus from north India on a few occassions but I have never seen specimens turn black due to stress. They only lose their patterns temporarily.

A very poor picture to show colouration. It seems to be quite jumpy at the moment.

The specimen.



Dorsal,adipose and caudal fins.



Head shot.


I am beginnning to think this is an aberrant Mystus seengtee. What do you think HH???

The specimen still bears the scars of collecting. Keeping it in quarantne until they heal completely. Hasn't eaten anything in 4 days. This is the first time I am seeing a Mystus specimen in so much stress.

A more 'regular' Mystus seengtee from Karnataka.

[Shovelnose, posts: 841]

Mystus cf. gulio from Tranquebar (east coast), Tamil Nadu,south India. This specimen was ca. 2" TL when the picture was taken.








Mystus gulio from the type locality, Ganges Estuary (east coast), north India.

At this size, there doesn't seem to be any significant difference externally. I will keep a tab on these fish to see how they grow/change. I am also trying to source some specimens from the west coast at the moment.

Some interesting Mystus as well as other catfish from Upper Assam this time.



Mystus dibrugarensis





Is this also Mystus dibrugarensis ???





Mystus cf.cavasius???

Two OT fish :



Hemibagrus menoda???




What is this???

Hemibagrus menoda???

Yes.

What is this???

I think this is Batasio spilurus

[Shovelnose, posts: 841]

Thanks HH. Any thoughts on the cavasius type specimen???

[Silurus]

Looks like a regular cavasius to me.

[Shovelnose, posts: 841]

Alright. Thanks HH.

[Shovelnose, posts: 841]

From Upper Assam again.



Any thoughts on this specimen???



Since this specimen was from the Ganga-Brahmaputra basin, I guess it is M.bleekeri and not any other similar looking species.




Mystus cavasius I think. The adipose is not seen unfortunately.

Hard to tell with the first one but potentially another dibrugarensis?

The second one has the long adipose of bleekeri, the 'angled off' adipose, and from what I can see of the fontanel it seems to match.

Hard to tell with the first one but potentially another dibrugarensis?.

The adipose seemed off to me, because of the angle perhaps.







I am still under doubt as to what these are.

[The.Dark.One, posts: 1438]

The pic showing the dead/preserved specimen - the anterior edge of the adipiose fin does look different but this could be due to death/preservation. It looks a little bit shrunk/folded in the image.

[Shovelnose, posts: 841]

True, it does look folded. I will try to source better pictures of that specimen sometime soon.

[Shovelnose, posts: 841]

Specimen from the Halali River,Madhya Pradesh,India. Just a coloured up M.bleekeri I think????
