Doradidae from Kabalebo river

Post by kamas88 » Fri Apr 14, 2017 10:05 pm

Hi,

from Kabalebo river in Suriname:

Image

If I remember correctly it was rather small (~6 cm), I guess a juvenile ?!
This one does not seem to fit to any of the doradids listed for Corantijne river system in Suriname or is it just due to the small size, any ideas, is this a Doras ?

Cheers,

Hi Karsten
Looks very similar to a Tenellus, can't see any dark pigmentation in the dorsal fin? As am sure you know, the only dorad listed from Coratijne is Doras micropoeus, which almost certainly isn't this fish. Hopefully @Silurus can shed some light on it?
Regards
Martin

Hi Martin,

additionally there is Doras carinatus (and Acanthodoras cataphractus, Amblydoras affinis, Platydoras costatus, Pterodoras aff. granulosus) listed for Corantijne river which I also rather excluded.
My first thought was also "looks a bit like Tenellus", but I know close to nothing about doradids and Tenellus is not at all listed for Suriname.

Going by the Suriname checklist and my limited ability to ID this catfish group there are no options left...
Perhaps Tenellus leporhinos which is at least listed for Guyana or an undescribed Tenellus sp. ?!

Cheers,

I don't see why Doras carinatus has been ruled out. For one thing, it seems to me that the very short snout is a particular feature of juvenile fish.

This is a specimen collected from the Essequibo River in Guyana (photograph from FishBase):

A very close match, I think. The number of lateral scutes in the fish in the original post (>30) also support its identification as Doras carinatus.

FWIW, Mark Sabaj's revision of Doras also show the very short snout of the juvenile fish.

I don't really rule out anything, I don't have any literature about doradids nor any experience with this group.
I was just curious which species we have caught...
