The dead prawns (millions) is quite alarming. I have never seen a dead leerie there. I once heard of a farmworker who washed out an empty pesticede drum in a Mapumalanga canal and ALL the fish on the next 6 farm dams got killed.

That said, I agree with John that De Mond can be fickle. Some times there are heaps of juvinile leeries, other times you blank.
