A farmer, Mr. Tran Duc Chau, successfully bred European sturgeon, with over 15 fish doubling in weight in just two months. By the age of 30 months, these fish were sold at double the price of normal commercial sturgeon. The Romen Sturgeon Cooperative's farm now has over 10 sturgeon that weigh over 15 kg each. The farmer plans to keep these 'giant' fish to monitor their growth and maximum life cycle, which will be used for research and breeding purposes.
