As you may know, fish cage farming is not an individual simple product. It is a system with different modules instead.
What modules should you deploy in order to operate your farm better?
In this article, we are going to list all the items that will help you. Please stay tuned.
1. Fishnets
This is the most important component of a fish cage farming system. The nets should be tough and firm so that fishes cannot easily escape. They should be inexpensive and easy to operate. Normally the nets are made of metal mesh, synthetic fiber, and other materials.
This is the most important component of a fish cage farming system. The nets should be tough and firm so that fishes cannot easily escape. They should be inexpensive and easy to operate. Normally the nets are made of logs, bamboo, metal mesh, synthetic fiber, and other materials.
- The original net cages were made of logs or Moso bamboo. They were inexpensive and easy to get. They have been used for a long time. The advantages were their thickness. They could prevent enemy species from attacking and fishes from escaping. The disadvantage was its short life cycle. At present, it has been basically eliminated.
- The metal mesh is usually made of wire and rolled by the steel plate. The net is strong and can prevent enemy species from attacking. But it is easy to rust. It can be antitrust by painting or coating. Due to the high cost and complex assembly, this type has been basically eliminated.
- Compared with natural fibers, synthetic fibers have more advantages. They are not subject to natural conditions. Synthetic fibers are characterized by high strength and lightweight. They have the advantage of easy washing, quick drying, and good elasticity.
2. Frames
The frame is designed to fix the fish farming system. It makes the fish farming cage into a certain shape. The materials of the frame are usually bamboo, wood, steel tube, and plastic pipe. The design of the frame is quite diverse based on live stockings and water regions.
3. Buoy
The buoy devices are the ones that can make the fish cage farming system float in the water and keep a certain shape. Most of them are plastic floats. The bamboo frames can be also used as buoys.
4. Sinkers
The fish farming sinkers are the ones that make the cage sink. So that the cage is not affected by the wind and waves. It keeps the cage in a certain shape in the water. Generally, the sinker materials are with high density. They are such as sandbags, stones, cement blocks, iron blocks, and lead blocks. The lead blocks are dense and antitrust. But the price is higher. Irons are also dense with lower prices. But they are easy to rust and they will damage the nets.
5. Mooring systems
The mooring systems are to fix the cage in the waters. Usually, people use anchors, ropes, cement piles, and other accessories. The fixed net cage is usually fixed with cement piles. At one end of the rope, it is attached to the angle. On another end, it is attached to the pile. The rope should be long enough, so the cage will not be immersed in the water when the water level is raised and down. The floating cage is usually fixed with an iron anchor. The size of the anchor is usually determined by the water flow and fish size. The anchor rope usually uses an iron chain, polyethylene rope, and white-brown rope.
6. Floating docks
In order to easily feed fishes and manage cultivation, the cage and embankment must be connected by bridges. The bridges consist of foot piles, beams, and springboards. The feet, beams, and springboards are generally made of wood.
Floating wharves use cans or gasoline tanks as floats. Empty boats and anchors can be used as a floating wharf in large aquaculture farms as well. It can be built as a management room, providing rest and storage.
7. The accessories
- Bottom net
The bottom of the cage should be equipped with a net. It can improve bait utilization, reduce bait loss, and get better feeding.
- Food table
The food table is the place where people feed the fish. The table is usually in the square. The table can be made of wood. The baits are put into the middle of the table. When the baits sink down vertically, the fish can eat at the bottom. These devices are very important for fish cage farming feeding. It can effectively improve bait utilization and reduce feed loss.
7. Subsidiary facilities
Except for the listings above, we still need some extra fish farming facilities in order to implement successful fish cage farming.
- Small boat
It is used for transportation and feeding. It can be a motor or non-motor boat.
- Washing machine
Because they are put into water for years, the cages are easy to be attached to algae. These might cause poor water quality in the cage. So a high-pressure spray gun is used to wash the net.
- Bait machine
This is useful for freshwater cultivation, especially when the feeding regions are broad and large. With a bait machine, the baits can be spread evenly, which is very for feeding. It can improve bait performance and reduce feed loss.
- Meat winch machine
With it, people can cut the baits into smaller slices. It is very helpful to reduce human labor and improve feeding efficiency.
- Freezing equipment
When people use smaller fish as feed baits, freezing equipment can be a good tool to cool and store these baits.
- Spare meshes
They can be used for repairing and replacing when the cage is damaged.
- Oxygen increasing facilities
They can be used for repairing and replacing when the cage is damaged.
