Redfin Shiner. These were pretty rare, we only found one in our collections. Many specimens do not actually have red fins. Found at our second site which was fairly rugged with very little bank making collection difficult.
Ghost Shiner. We only found one of these. Site was pretty rugged, a lot of debris in the water and dip-netting was very difficult because there was little bank to stand on.
Bullhead Minnow, found in small abundance. Habitat had a lot of debris and it was difficult to sample here. Water was very deep and shaded.
Mimic Shiner, similar to ghost shiner. Distinguishable by the lateral line that the ghost shiner doesn't have. Fairly thick debris in the water at this location. Mimic shiner is less transparent than the ghost shiner.
Blacktail Shiner, easily identifiable by the black dot on the tail. Blacktail shiner was the most abundant fish we encountered.
These unidentified fish are living in a very fast flowing river high in the northern flanks of the Hindu Kush mountains. I have seen them being caught at the weir of a mini-hydro electricity project. Boys catch them in nets as they attempt to 'jump' up the weir... seems like a good time for a fish pass to be implemented.
To my untrained eye, they look like some kind of trout... maybe a Schizothorax of some sort?
