Inilah cara agar kolam berudu kodok lembu subur. Pond for bullfrog or tadpoles has to fertile. It has natural foods in high population, with variation kind, and size. Natural food is very important for fishes growth. It has to stocked during cultivating.
One of method for fertilizing pond is done pond preparation. Pond preparation activity are drying, dike improvement, flating bottom, diging canal, liming, fertilizing, and watering.
Drying
After harvesting, pond surface is wet, and dirty. There are many polutans, like poison, secretion, rest foods, predators, and diseases. It’s very not well for a pond. Because, productivity that pond is very bad. The fishes can’t live well, and can attacked diseases.
Therefore, ponds must dried. Beside for lossing the polutans, the aim of pond drying also to simple in dyke improvement, ftating bottom, making cannal, liming, and fertilizing. Drying are 5 – 7 days, or depent of seasons
Dike improvement
After harvesting, dyke also break. Because slide, the dyke surface isn’t flate, and there are many leak. It’s very not well if it watered. Because, the deep can’t kep. In this situation, the fishes can’t live well, and there are many them go out of pond.
Beside that, the ponds willn’t fertilize. Baecuse, fertilizer will go out of ponds. There isn’t for them to feed. Otmaticaly, they can’t growth fastly. Therefore, before using, pond dike must be improvemed. The dike improvement method is with closed all of dike surface by mud, and bottom land.
Canal diging
After harvesting, cannal also is shallow, closed muds. Whereas cannal is very useful for fisfes. Becuse, they can’t avoid sunshine when afternoon. Sometime sunshine is very hot. Beside that, shallowy will difficult when harvest.
The fishes willn’t enter to cannal, but will distribute to other side, so that it can’t catched. This situation can cause the fishes injured, and finished it dead. Therefore, cannal must be dug. Cannal diging is done with dig, and throw away to other side.
Liming
Also after harvesting, low in pH (puisanche of the H), and alcalinity. This situation cause ponds low in productivity. The ponds can’t make good environment. Water quality will bad where oxygen always low. It’s make the fishes can’t free in breathing, and low in feed, so that they will depress, and high in mortality.
Therefore, the ponds must be limed. Liming is aimed for normaling pH. The best of pH value are seven, lower than seven is bad. The other aim of liming is killing diseases. The kind of lime is CaCO3. Doses’s depend ph value, and kind of land. Liming is done with spreading to the all of pond part, in wet or dry. Dosis of lime are 25 – 50 gr/m2.
Fertilizing
The fishes need natural food. Natural food will be fed by them, and make them growth fastly. Condition of natural food are smaller than mouth open, high in protein and easy in digest, slowly in movement, easy in production, cheap, and use local materials.
The ponds willn’t fertile without fertilizer. Therefore, fertilizing is very interesting to make it. Fertilizers are organic and inorganic. Generaly, Indonesian culturis use dry chicken manure, and dry quail manure. The fertilizing method is with spread it to the all of bottom surface.
Watering
After fertilizing, pond watered by closing outlet, and opening inlet. Don’t forget in the inlet placer filter, so that predator don’t enter to the pond. Inlet stoped if water has 40 cm in high. And then, pond soaked for five days. Natural will appear there, and pond has ready.
