I don't think fin clipping as a method of id would work in his situation
since he will be studying swimming and the fin clips could have an impact
on the fishes' swimming pattern, performance, etc.

You might try freeze branding using a metal "number" cooled in liquid 
nitrogen, this produces a readable brand after a few hours. It is easy to 
produce a set of irons to do this - copper is best.

You can find the numbered copper branding iorns alredy made. Just go to
a veternary supply house ask for horn branding iorns. The are used to
brand numbers in the horns of cattle.

If you can't find them localy
Karl Myer had them the last time I was in there his number is
405 335 2158. Make sure the size he has suits you. If you call him tell
him I said hello to him and his wife Donna.
