The binni (Mesopotamichthys sharpeyi) is a species of cyprinid fish endemic to the Tigris–Euphrates Basin in the Middle East.

[3] This fish mostly inhabits lakes and marshes, especially in densely vegetated places where it also lays its eggs, but periodically it moves into rivers.

Their fishermen traditionally employ an unusual technique of spearfishing from a line of boats or poison-fishing with flour or dung laced with toxic Digitalis or Datura; until recently net-fishing was mostly restricted to the Berbera tribe and held in low esteem.

Since the 1960s however, large-scale fisheries have also been developed; once of prime importance throughout Iraq, the marshland fish stocks presumably declined notably following the draining of the Mesopotamian Marshes.

Now mostly dried-up following the draining of the Central Marshes, its name attests to the former abundance of this fish and possible use as spawning ground (Umm is Arabic for "mother", but does not necessarily imply procreation).
