They look like minnows to me. But I can't get a big enough image on the tablet device to be sure. The movement does not suggest a bottom grazing fish like gudgeon and barbel.
Near where I live there is a bridge over a tributary of the Vienne. It is a barbel nursery with gudgeon sized barbel constantly feeding on a shallow gravel stretch. You can see them turning on their side to extract something from the gravel. By now last years hatch will have moved downstream a couple of hundred metres and feed over a sandy stretch in slightly deeper water. They hoover the botton in a loose shoal, moving upstream before drifting back downstream and starting over again. They grow to about 8 or 9 inches then drop down further close to the confluence. The confluence is full of barbel up to a couple of pounds.
