Look like any other Senegalus to me.
Seem to lack the Turkana head shape.
Turkana Senegalus have no "white markings" through the eyes.
Do you have documentation of source locale? When is the catch dated?
The last catch of Turkana Senegalus, was many years goo, by the guys of Big-In.
They had a exclusivity right with some other groups to fish in the Ethiopian end or the Lake where these are found.
And that batch are all now very large or dead. (way larger than 30cm)
Non native fishing is not only banned by UN law in this area, but also incredibly dangerous as it's a water and food source for rebel soldiers.
They are rarely found in the Kenyan end due to human population and depth issues.(Same with the Turkana PBB)
Just curious.
