attitudes change with the times... but mostly becaus the die-hard 
proponents of the other ideas have died off...

Since we treat each population as a species already we have to 
regard the extinction of a population as the extinction of that 
species. As Prof. Watters demonstrated with the KNP transfer that 
although the wild population may be extinct captive reps. of that 
population can be reintroduced at the site of original collection as 
well as other sites near by. We could well build a pond at Kutunse 
in the future and reintroduce the walkeri (although the odds are 
slim...).

Concerning retricted ranges, then the N. fuscotaeniatus is a prime 
candidate. Due to floods and degredation of the roads the Kitonga 
populations are now unaccessable for the forseable future (correct 
me if I am wrong...). The same can be said for most SAA which are 
only known from one pool (which is very quickly turned into a 
parking lot...). N. korthausae may also be a prime candidate being 
retricted to Mafia Is. only. Imagine that, one of the most common 
fish being "threatened" and put on a SMC.

Oh well, enough rambling...
