10. Nguyen Van Tuan: Machine for detecting and treating choking shrimp
    In my village, every family has been living by breeding shrimps. At harvest home, the amount of shrimps always goes larger than the volume of the ponds and lakes, the volume of oxygen is not enough to support the breathing of the shrimps. My idea is to make an accessory which is automatically to excavate phenomenon of shrimps’ asphyxia oxygen, the accessory will automatically close the electric circuit to run an air bubbling machine, immediately support more oxygen to herds of shrimps. When not enough oxygen, the shrimps will float to the water surface, the light of headlamps and an electric jack will excite them to move strongly on the surface of the ponds or lakes. A signal sensor through the movement of the shrimps will transmit the signal via a relay to close the circuit and run the air bubbling machine, more oxygen will be supported immediately, and that helps shrimps healthy and normal. The accessory comes with some options such as an alarm to detect thefts and an alarm to warn breeders that shrimps float to the surface. If it’s complete, this accessory would be applied generously in reality and life, to avoid any damages or risks for the breeders at the harvest home.
