this posting discusses more than 10 ways to farm fish with a recirculating system for beginners
you should read through and hear slowly and gradually hence that by yourself comprehend and can be applied toward your each day existence.
A recirculating system is a fish farming system in which the water contained in aquaculture ponds is recirculated through various processes so that fish waste, food residues and compounds, as well as toxic gases resulting from the secondary effects of fish waste, can be trapped in a settler. tank so that the water that returns to the pond is clean and free of various impurities.
Therefore, healthy and stable water can prevent the development of harmful bacteria, maintain fish durability and health, increase fish appetite, and maximize growth to minimize mortality rates.
If you are interested in learning or using this method in your fish farming, let’s first read my article this time on 10 ways to farm fish with a recirculating system so that you understand the process and stages.
1. Understand the system
In fish farming with a recirculation system, you must first understand the system used, that is, by using a controlled water flow and a pump to drain the water. The first thing to do is to pump water and put it into the pool, then the waste water from the pool is poured into the tub.
The tub is a filter tub, which is responsible for purifying the water so that after passing through the water filter it can be reused to fill the pond water. The filtered water is again clean and free of dirt. (Also read about how to keep koi fish in a home pond)
2. Change periodically
The replenishment of the pumped and filtered water is carried out periodically according to the amount of water presented. Water changes are generally done by adding water from a reservoir that has been prepared to make the process easier. (Also read about how to care for silver arowana fish.)
3. Water drainage
The elimination of the water is carried out by the siphon method, that is, using a hose to which a filter has been placed at the end of the pond so that the fish are not sucked in or wasted. Item particles in the water will be removed so they don’t come back and mix with the water that has been cleaned. (Also read about African catfish farming.)
4. Power source and pump power
In pisciculture with a recirculation system, an adequate power supply is needed since the equipment used works with electrical energy. If the electrical power is weak, it will affect the pump and the water filter, so it is feared that the results will not be optimal and pose a danger to the health of the water or the fish in the pond.
The rest of the feed and dirt in the pond water will undergo a process of change and improvement in composition after 1 hour, so that most of the dirt has been sucked up by the pump. For that you must have a pump whose power exceeds the capacity of the pool. The comparison is, for example, the pool volume is 2500 liters, the pump power must be above 2500 liters per hour.
5. Filter tool (water filter)
The amount of fish feed provided and the power of the pump affect the capacity of the filter or water filtration device. The volume of the filter capacity must be able to support the flow of water so that the water does not settle too quickly to the bottom of the tank. (Also read about fish farming in floating net cages).
Choose a filter with a design that is capable of trapping and precipitating dirt, there are usually two, filtering directly using pressure and slowing the flow of water so the water slows down and dirt settles.
A circular filter is ideal because there are no dead sides, you spin the current and the fish will keep turning with the current.
There are certain types of fish that are more sensitive if cultured in a recirculating system, including ornamental fish and marine fish. Disinfection must be carried out periodically before the water re-enters the pool. (Also read about how to care for arowana fish so they grow fast.)
This can be done by using a UV lamp, the water going back into the pool is passed through a pipe covered with a UV lamp so that bacteria exposed to UV radiation are killed and the water coming out is clearer.
7. Place of support or swimming pool
Fish farming with a recirculating system requires a slightly enclosed spot or pond, still requires small doses of sunlight to kill germs, heat the water, stimulate fish bone growth and health, and provide a fresh flavor to the group to increase appetite. . It has a roof or cover in some parts that are transparent. Sunlight should not enter fully from morning to night because it stimulates the growth of algae or algae.
The pool water will still decrease due to evaporation, but it doesn’t really matter because new water can be added. Fish farming with a recirculation system is suitable for areas with little water or during the summer.
In these seasons there is generally more evaporation, enough water can be provided in the water reservoirs that have been arranged
9. Take care
When farming with a recirculating system, discipline is needed every day in the inspection and maintenance of the tools that play a role in the system. Periodically check pump and filter, sediment build-up, water quality, etc.
Because if there is a problem such as leaky pipe or damaged pump, it will surely be a big hindrance in the recirculation process and disturb the comfort of the fish in the pond and affect the cleanliness and health of the water.
10. Feed at the Right Level
Above, the cultivation process in the recirculation system has been fully explained, when using this method, you must maintain the cleanliness of the water, dirty water will further aggravate the task of the tools that play a role. You can maximize the cleanliness of the water by feeding your fish at the correct level, without intentionally overdoing it.
This is important because feed that is not consumed by the fish will be wasted and become dirt that collects in the water, if this continues it will increase the load on the recirculation equipment. Give everything at the right level and use the tool wisely to make it last longer and give you maximum benefits.
So far friends, in this article, fish farming with a recirculation system does require more costs, but it is worth it for the comfort and benefits obtained. Hopefully this article will be useful and increase your knowledge, thanks for reading. Greetings from the author.
