Mekong delta is a low land with many rivers so the poor families don’t have access to much land. It is easier for them to raise eels in front of their houses in small ponds or nets. But why eels? Eels are easy to feed, you just need snails which you can find everywhere in the rice fields. They take only 5 or 6 months to grow. You can also just catch them in canals with an eel-pot. It is a good investment as the selling price is higher than fish. You can sell eels for 60 000 đ/kg whereas you can sell fish for only 25 000 đ/kg.
