In order to increase the growth rate and yield of squid, it is generally necessary to feed compound feed when raising squid monoculture or squid. The main squid is generally not suitable for squid, grass carp and other strong ability to catch food, but with squid, squid is relatively good. When salmon and trout are stocked together in various ponds, feed powders fed to other fish are a good source of food, and generally no separate feed is provided.
The requirements for cod formulated feed: After ingestion of eel, it is mainly on the surface of the water body, with its head exposed to the water, slowly swimming around the food field and actively feeding compound feed, which requires the feed to have good floatability in the water. Generally, the particle size of the pellet feed is between 0.3~0.8mm. The current commercial materials on the market are usually powders. The buoyant feed utilization can reach 90%.
Feeding precautions: Pay special attention to avoiding waste. When the hand is sprinkled, the feeding should be done a small number of times and the feeding rate should be slowed down each time. Under cage culture, the feed is generally packed in a cloth bag and the fish is trained to touch the cloth bag so that a sufficient amount of food can be obtained according to the fish body. The best choice for the feeding point in the reservoir area is to use a bamboo rack as a basket rack on the upwind, quiet, and deep water depth, and sprinkle the powder in the middle of the basket rack. If necessary, you can also splash the powder after adding water, but be careful to mix the water evenly.
Removable Oxygen Cylinder Filling System
Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure and fill in cylinder with an oxygen booster and compress the oxygen purity to 150bar.
With a customized container, all the parts can be involved in, and removable with a vehicle.
