The alternative name for the sunbleak is the motherless minnow. The Environment Agency claim that motherless minnows can spawn up to twenty or thirty times a summer and that large populations can appear "from nowhere" in a single season.
I had decided to return to Peterborough via the Viaduct Fishery in Somerset which contains a huge head of these fish.
To cut a long story short I had loads of motherless minnows and they are by far the smallest and least interesting species that I have caught in the challenge to date. Apologies, even after employing the macro function on my camera the distinct short lateral line (the distinguishing feature of the species), is not visible in the photo.
With such a head of small fish it is no surprise that viaduct produces huge perch. Maybe one day I will return to explore the predator potential of this attractive little fishery.
