Selling fighting fish In singapore market long-long ago

One of my uncle from Singapore come to stay at our house, two days ago he told me about those day how he rear betta in those day he was still a boy, around fourty years back. He and his friend spawn the fish by putting a pair of fish in a tank and put in the dark place. Next after the fish have lay the egg on the bubble nest, they quickly took the female fish out from the tank and left the male to take care the young. for the next few week they will try to catch some live food (daphnia) in the drain, earth worm by digging a hole here and there. finally when the fish grow big enough they will took them to the market to sell, each fish sold 20 cent at that time. Most of the time they can spwan around one thousand fighting fish from a pair of fish. Now i think for kid in Singapore can never have this type of hobby...
