For making a farm of bullfrog, you have to have some facilities. All of them are better built in location your self. Because, if you built in the other, you need addition cost. It will be effected in production cost, and descrease profite. But if you don’t have, don’t worry, you are still do it, and you will not lossing profit’s.
The bullfrog culture facilities consist broodstock pond, spawning pond, hatching pond, rearing pond, and growing pond. In the big scale, except them, also need other facilities, worker houses, ware houses, and laboratory. Of course, these will support to principal facilities. This article will helf you in building all of them.
1. Broodstock ponds and growing ponds
Broodstock ponds are places to cultivate broods after or before spawn to mature. It contructed by cement, these also named tanks. The tanks have 2 m in wide, 2 m in length, and 1 m in high, and made line. Every line has 10 tanks. Along the line are closed by transparant roop for protect direct sunshine.
Whereas growing ponds are places to cultivate young bullfrog to adulf, or consumtion. Contruction, and size are like broodstock ponds. Because that, broodstock pond can be also used for growing pond.
Every tank has five parts, are inlet, outlet, bottom, walls, and fences. Inlet is hole for irrigating water. It made near of water resources. Outlet is hole for drying. It made in the back, near of exit canal . Bottom is place to stand bullfrogs.
Wall are part in around of the tank, and it has 20 cm in high. Surface of bottoms and walls must be made soft, so that heart bullfrogs. Fences are made by net, and it has 80 cm in high.
2. Spawning ponds and hatching ponds
Spawning ponds are places to mix males, and females so that spawn. The contruction all of part are like contruction of broodstock, and growing ponds. But the walls have 40 cm in high, it higher of them. Because, water in the spawning is higher of them. Fences have 60 cm in high, it shorter of them.
The spawning pond must be built in the back of farm, or in the sillent place, or far of the people activity. Because spawning only will be occured there. Whereas hatching ponds are places to take care of eggs so that hatch. But it can be built every where, include near of people activity.
3. 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.
