Using a reservoir cage to raise squid

At present, the breeding methods of squid include the “Four Home Fish” pond culture, shrimp pond culture, and reservoir breeding. Among them, the reservoir culture has fresh water and eats mainly natural food. The produced fish has good appearance, good quality, delicious and delicious meat, rich nutrition, good market sales, low cost, and remarkable economic benefits. It is subject to a large number of farmers and consumption. The favor of the people. This article will introduce the breeding techniques for the main reservoirs of squid and polyculture in the reservoir as follows:
The choice of water area is to choose a wide water surface, a sunny wind, and a bay with a certain flow rate, which is conducive to the exchange of water bodies inside and outside the cage. The depth of water should be more than 3m, the water quality is fresh and more fertile, and the dissolved oxygen is rich. There can be more discharges of domestic water in the upper reaches to increase the source of organic fertilizer in the water area. The surrounding environment must be free from other sources of industrial pollution. In addition, keep away from the docks and the main fairways to avoid noise caused by the boat's normal feeding and strong currents causing the fish to escape.
Net cage selection and installation cages are polyethylene closed rectangular nodule cages, specifications are 10m8m, height is 3m, mesh 2a = 4? ~ 6?, cage spacing is about 0.5m, cage frame made of Chinese fir The use of plastic foam can increase buoyancy, and the lid of the box should sink into the water. The four corners of the cage should be tied with stone to facilitate the relaxation of the cage.
Cage culture
1. Fish stocking. Precautions for stocking cages should be soaked with potassium permanganate at 30?/L for 24 hours, and water should be installed between 5 days and 7 days before the fry is placed in the box. The algae attached to the mesh become smooth to prevent fish. Body mechanical damage.
The stocking stockings are larvae, cockroaches, and breams all weighing 120g/tail to 150g/tail, which are robust, smooth and glossy without damage to the body, and have strong swimming ability.
Stocking density: Carp 120 to 160 per carp, Carp and Carp 10 to 15 each. Before stocking, soak in potassium permanganate of 20?/L with 40 g/L of saline for 5 minutes to 10 minutes.
2. Feeding.
Carp is a filter-feeding fish and mainly feeds on plankton in the water. However, due to the slow growth of natural food in the cage during autumn and winter, it cannot meet the fish's food intake. Some fish should be splashed in the cage according to the amount of plankton in the water. Organic fertilizer helps to enrich fertilizer and enrich biological feed in water. When necessary, the special artificial feed for eel can be put into the bag, and the net bag is suspended in the middle of the cage and fed once a day at about 12:00. In addition, a 5W energy-saving lamp is installed on the water surface in the middle of each cage, which should be powered by electricity to lure the zooplankton outside the box into the tank, increasing the density of zooplankton in the tank, and there is also a partial phototaxis on the water surface. The insects fall into the box, providing live fish for the fish and accelerating the growth of the fish. The lighting of the cage at night is also convenient for management, and it can prevent the motor boat from accidentally hitting the cage and causing fish escape accidents.
3. Daily work.
Adhere to the inspection box regularly check the growth of fish, reasonable feeding, careful observation, analysis of fish.
Periodically inspect the box to inspect the cage regularly and find that the damage was repaired in time to avoid the escape of fish and squid into the box. Strengthen the cages in the strong winds and heavy rains, and lift the cages in time.
Timely shift should be based on reservoir floods, changes in water level, timely adjustment of the water quality of the net cage position, to avoid adverse breeding environment, select the appropriate conditions.
4. Fish disease prevention and control.
"Prevention as the main, health management," every 10 days to 15 days with bleached powdered pulp and hot box full of sprinkling, purify water quality, monthly use of pesticides and sterilizers full box spilled. Diseased fish and dead fish were removed in time, and some cage fish bodies were isolated and prevented from work when they were onset.

Removable Oxygen Generator

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.

With a cabinet for small capacity or container for big capacity, all the parts can be involved in, and removable with a vehicle.
