Many people in India call Arowana to be Vaasthu or goodluck fish.
Arowanas are very popular here, but most of the people wont go for an asian because of the expensive price tag.
People here (most of them) dont want to spend so much on a fish.
So they settle for a silver, australian or green mostly.
Remember China and India are the largest markets in the world. So more customers.
So if Indian farms began to breed asian aros, to increase the local sales they have to bring the prices down in India.
In international market to get well established they should give quality fishes for very good competitive prices.
But quality is not something you can achieve in a short term, even if Indian farms breed asian aros its hard to compete with countries like Malaysia, Singapore and Indonesia interms of quality initially.
So reducing the prices will be a good option to compete in international market.
When there is more output, the demand comes down and hence the prices comes down.
I have not got any problem paying top dollar for a top dollar aquarium fish. Meaning here in the USA legal CITES farmed paperwork high quality Chilli Red Asian Arowana or Cross Back Golden Asian Arowana. I won't buy or consider black market Arowana's that will land me a huge fine, cause problems for my career or further endanger this spectacular species in their native habitat. I think legalization in the USA would take more conservation in there native habitat and political lobbying. However if India started Arowana farming I think it would increase the opportunities to work with these spectacular species unless your scared of the price tag of this endeavor.
