Simple Techniques for Fish Cultivation in Ditches for High Quality

Simple Techniques for Fish Cultivation in Ditches for High Quality – For this, another example of a business in fish farming with a rapid water system is fish farming in trenches. This system utilizes ditches or waterways for fish farming without having to reduce or change the function of the ditches or canals.

This system has developed very rapidly, this is because the cost of implementation is relatively cheap and there are quite a lot of available ditches or waterways that can be used for this business.

Advantages of Fish Farming in Trenches

Besides being cheap, fish farming in trenches can provide several advantages for farmers, because they are:

• Implementation costs are relatively low and production is quite high.
• The profits obtained will increase the ability of farming families to meet their nutritional needs.
• The bulkhead that functions as a barrier to the movement of fish will indirectly hold the garbage in the ditch or water channel, making it easy to clean.
• Food remnants and waste products of metabolism will soon be wasted and decomposed into elements that can be useful for plant growth.
• Because the principle is the same as the swift water pond system, fish can be kept at a high density level.

Ditches or waterways suitable for fish farming have a water discharge of between 100 and 125 liters per second. And while the water depth is not less than 40 cm and not more than 1 meter. However, if there are no ditches or waterways that meet the requirements as above, other ditches or canals can also be used, and of course the results will be slightly different.

Cultivation Materials And Construction In The Trench

The main materials needed for fish farming in ditches are wood, bamboo and wooden wire nets that are used, they do not need to be expensive but must be durable enough to be immersed in water. And generally farmers use albasia wood which has a length of 3 meters, a width of 7 cm and a thickness of 7 cm.

The bamboo that will be used should be chosen which is old, straight and long enough. After cleaning, the bamboo is then cut into pieces with a length of 70 to 100 cm, and a width of 5 cm.

If a wire net is used, choose a mesh size that matches the size of the fish to be reared. Cut the net with a width of 70-100 cm and the length is adjusted to the width of the ditch or water channel.

Pool Making

After obtaining a location that meets the requirements, making a pond can be done in the following ways:

Make a Wooden Skeleton

Make a wooden frame with a size that is adjusted to the width of the ditch or water channel. So that this frame cannot be washed away by water currents, it is better to plant it to a depth of 20 cm on each cliff of a ditch or water channel.

The framework consists of two pieces of wood that are installed crosswise according to the width of the trench or water channel. The location of these woods is parallel to each other, and one wood is on top of the other wood with a distance of 40 to 60 cm.

Install Bamboo Cuts

Attach the previously prepared bamboo strips to the wooden frame. One end of the bamboo must be embedded into the bottom of the water to a depth of 10 cm and the other end should rise to the surface of the water at least 20 cm high.

The distance between each piece of bamboo is enough 2-2.5 cm or according to the size of the fish to be kept if a wire net is used, then the bottom must also be planted to the bottom of the water to a depth of 10 cm and the top should also rise to the surface of the water as high as at least 20 cm.

The length of the trench is not too big

It is recommended that the length of the trench used is not too large, the ratio between the length and width of the pond should not be more than 2:1, meaning that if the width of the ditch or water channel is 2 meters, the length of the pond is 4 meters.

Two pieces of pond skeleton must be made

The pond framework must be made of two pieces with the distance from each other determined based on the width of the ditch or water channel. This framework serves to limit the movement of fish, so that it will be easier at harvest time.
