Broodstock ponds, and growing out ponds
Broodstock ponds are places for cultivating broods after or before spawn up to gravid. Whereas growing pond are places for cultivating youngfrog up to adulf, or size for consumtion. The cotruction, and size both of them are the same.
The pond has 2 m in wide, 2 m in length, and 1 m in high, and made line. One line has 10 tanks. Along the line are closed by transparant roop for protect dirrect sunshine. Every pond has six parts, are tank, inlet, outlet, bottom, walls, and fences.
Tank made above ground, by length 2 m, wide 2 m, and high 10 cm. It’s principal part of pond. Whereas tank has to strong, don’t leak, and catch water. In order to function well, tank contructed by stone, and cement, and made by careful. Fences, bottom, walls and outlet made in this part.
Bottom, and walls are place to catch water. Bottom also place to stand bullfrog. In order to injury, bottom, and walls made by soft cement. Bottom made slope gently to outlet so that tank easy dry. Walls has to strong, pillars of fence stick there.
Outlet is hole for outing water when drying, or harvest. This part made in the back of pond, or related by out canal. Outlet made by paralon pipe, 2 inches. Fences made by net around of the tank, and it has 80 – 90 cm in high. Fence function by keeping bullfrog so that out of pond.
Inlet is hole for irrigating water when preparation of pond. It made near of water resources, by paralon pipe 1 inche. In this part setted water tab for regulating discharge. Inlet related dirrect to reservoir. If all part of pong has made, pond ready to used.
Spawning ponds and hatching ponds
Spawning ponds are places for mixing males, and females so that spawn. Whereas hatching ponds are places for taking care of eggs so that hatch. The both of them must be built in the back of farm, or in the sillent place, far of the people activity.
The contruction of part ponds are like contruction of broodstock, and growing out ponds. Because it will be used for spawning, the walls have 30 cm in high, or 20 cm higher than broodstock pond, and growing out pond. Fences made 70 cm in high, it shorter than both of ponds.
Rearing ponds
Rearing ponds are places to cultivate larvas to young frog. It contructed by land, has 5 m in length, 4 m in wide, and 60 cm in high. Rearing ponds has five principal part, are inlet, outlet, bottom, dike, and canal.
In a period, a farm must has 3 ponds, are for first rearing, twice rearing, and thirth rearing. In order fertile, and high in natural food population, rearing ponds must be prepared, so that larvas live finely, growth fastly, and high in survival rates.
