Without a doubt, can boost your aquaculture if you use fish cages right.

Just like everything else, this practice also has pros and cons. You can’t just simply invest a big amount of money and wait for your money back without doing anything more.

In this article, we are going to reveal the cons and pros of cage farming and provide a tutorial for the right people to decide.

Generally speaking,

Cage culture has many characteristics like flexibility, efficiency, and high yield. Fish cage is easy to set up and the fish can grow up quickly. The fish cage is usually not large. When the water territory is not good for fish, people can quickly move to another area. By moving to another place, people can continue fish cultivation and avoid property loss by doing so. Most of the time people do this because of terrible wind, heavy pollution, or low water level. Generally, the net cages are set in larger water or in smaller quantities. There is only one fishnet between the inside and the outside. The cultural environment is very close to true nature. The water flow can pass through the fishing net. The bait and metabolites can be discharged through the mesh. Thus, the dissolved oxygen and plankton inside the cage are very rich. It meets the needs of the stockings. It also provides the essential conditions for culture. Meanwhile, fish cage culture is the same as poultry farming. The livestock is restricted to a very small area. It limits energy consumption. Energy consumption decreases greatly, making livestock grow faster.

The pros

  • It makes full use of natural bait and water. People can raise silver carp and tilapia in reservoirs, ponds, and lakes. With this pro, people can reduce commercial bait consumption.
  • It can save land and labor to dig ponds. With one time investment, people can earn back all the investment after one year. Yet the cage can be used for five to six years at most times.
  • Fish cages can be used in a wide range of water areas, such as lakes, rivers, reservoirs, and other places. In this territory, no extra construction is required.
  • Net cage culture provides superior water quality. Mostly the cage is installed in slight water areas. The dissolved oxygen in water can be maintained at more than 5 milligrams per liter. Fish excrement can be quickly discharged out of the cage. It ensures a good water environment. Moreover, the fish in the box is restricted to a certain small environment. Within that, there will be less heat loss for fish. The growth rate of fish is faster and the feeding cycle is shorter. Culture fast and sell fast.
  • Cage culture is flexible and convenient for management. In particular, the floating cage can be removed from unsuitable water to suitable water at any time. It can raise livestock nomadically. Therefore it is convenient for commercial fish to sell on the market. Also, it is easy the transport and management of live fish. During cultivation, people can monitor fish activities and growth at any time. And the fish disease can be healed in time as well.
  • Cage culture can be controlled to reproduce. If tilapia is inhibited under high density, the gonadal is also easy to grow without a male.

The cons

  • Cage culture is limited by many natural conditions. If the water level is too shallow or too volatile, it is not suitable for cage farming. Also, it has to keep enough dissolved oxygen in the water.
  • The cage needs to be cleaned regularly. Net clothing should be washed frequently to remove the attachment. It can keep the mesh open by doing this. This ensures smooth excretion out of the box.
  • The feed may be lost through the broken net. So the net cage should be checked regularly. Preventing fish from escaping is a daily task.

As we can see, the cons and pros of cage farming. You can’t just take the cons and ignore the pros. What do you think? Leave your comments!
