Hi

Re the pic posted by Mel with the caption "Bushcraft wrote":

Without having searched for the original post, I assume that was in the KNP somewhere?

Really difficult to discern identifying features from that pic so I can only offer a guess:

Lowveld Largescale Yellowfish, Labeobarbus marequensis.
They are mostly seen in flowing waters of perennial rivers below 600m elevation.

Where I live (Lowveld section of the Blyde River) I often see them behaving like that, congregating in shallow, clear, flowing water over a sandbar. Well, perhaps they also do that in turbid water an we just don't see them then.

Wynand, can you help pse, you mention "Lowveld"are the Lowveld large scale Yellow Fish different from the Large Scale in the Orange-/Vaal rivers.
Thanks.

Hi Dup.

One can leave out the "Lowveld" -part of the common name. It does not distinguish this Yellowfish from any other Largescale Yelowfish. Largescale Yellowfish are restricted to lower altitudes in the Northeast of our region, so the Ichthyologists added "Lowveld-" just to be clear. The Smallscale Yellowfish is found in the same region but not below 600m elevation, hence its common name: Bushveld Smallscale Yellowfish (Labeobarbus polylepis). Again, the "Bushveld" part can be left out and it won't be confused with any other fish.

The Yellowfish in the Vaal/Orange you're thinking of the the Largemouth Yellowfish (Labeobarbus kimberleyensis). Its fully articulated common name is the Vaal-Orange Largemouth Yellowfish (siestog). There is also the Vaal-Orange Smallmouth Yellowfish (Labeobarbus aeneus) and the KZN Yellowfish (Labeobarbus natalensis) and, lastly the Clanwilliam Yellowfish (Labeobarbus capensis)

A bit confusing, perhaps? I guess the regional designators for Largescale-, Smallscale-, Largemouth- and Smallmouth- Yellowfishes were added to keep the group tidy in our minds.

So, six species of Yellowfish within RSA borders:
Largemouth (Vaal-Orange)
Smallmouth (Vaal-Orange)
Largescale (Lowveld)
Smallscale (Bushveld and escarpment)
KZN (Guess where?)
Clanwilliam (Restricted to Clanwilliam Olifants system, and vulnerable)

and disgorged same again immediately when the coast was clear! This happened quite a couple of times and we had great fun in watching this behaviour as we saw something like that never before.

Interesting find by Pumbaa, would love to know what it is :-?

It's a tilapia...Kurper!

A mouthbreeder common across Africa!

So the little fish around jump into the mom's mouth if there is trouble!

One of the smaller species, obviously! ;-)
