Important factors in making tarps for fish ponds

Important factors in making tarps for fish ponds

There are several important factors that must be considered in making the pool tarp, including the following.

a. Types of fish to be cultivated. This is because not all fish cultivated in ponds suitable tarpaulin. In fact, there are several kinds of fish that is not enough just with water as the medium of life, but requires additional media mud. For example, eels require the muddy bottom thick and contains organic material.

b. Fish size. This is because the size of the fish pond effect on height. For example, for seeds, young carp are not recommended to be placed into a pool made too high, but should be enough height 60 cm with 20-40 cm of water.

c. The balance between the volume of water with supporting framework must be strong. When the volume of water or the volume of mud media (for eels) pressure is quite large, frame buffer must be strong. Similarly, the ability tarp material, if thin, should not put the fish with a large volume that is not broken.

d. Basis for the laying of the pond should be flat tarp, as well as the framework does not have material that can make sharp torn or perforated sheet. If the land is not flat bottom, should be a layer of banana trunk or stem of rice husk. To frame using split bamboo, bambo parts should be placed on the outside and if the frame is made of iron, should not that easy to use because it can make a rusty torn tarp.

e. At the time of harvest and post-harvest treatment required both that the tarp was not damaged and can be used for subsequent operations.

f. Drainage pond that is made by punching holes in the tarpaulin should be done carefully so that the canvas does not leak or a sewer system to the capillary (with a suction hose).
