Of course it's a problem. I'm not sure about Indonesia, but in Thailand catching and selling the young, while eating the grown is obviously unsustainable.
If Pulcher were eaten in Thailand, you can bet your house they eat them in Cambodia, and more than likely in Vietnam too. Did you know that pulcher in it's last years in Thailand would fetch more on a dinner plate in the posh Chinese restaurants in China Town than it would being sold into a fish tank! If all these little fishes we see are really Pulcher, and the catch them with nets, how do the big ones survive? It's impossible to fish with nets for small fish and not kill big fish by accident.
Classic Chassis is a tough act to follow in this thread/discussion.....By all accounts given the future of the Datnioides apears to be very bleek.I made a thread raising this concern a year or so ago when I noticed the stores here with tanks full of small dats in this area and probably elsewhere,but they were not as small as Gage has reported, which is not good at all......Human predation of the large dats coupled with mass capturing of the small ones and no captive breding leads eventually no dats in the wild.
