How to reproduce traffic lights

The sexual maturity of broodstock is 10 months. Male and female differences are more difficult. Male fish are generally more slender; female fish are more hypertrophic. In the bottom of a fish tank of 30 cm X 25 cm X 25 cm covered with hair silk grass. Water gentle 5 to 26 degrees, water quality pH 5.6 to 6.5, the regulator section should be carried out slowly, so that the broodstock has a process of adaptation (or choose the water of a very soft double-distilled water, adjust the pH, oxygen reserve). A pair of broodstock was placed in the evening, and the females usually hatched larvae at dawn on the second day. After 4 to 5 days, the larvae ate and ate. Female fish hatch 200 to 300 grains each time.
The propagation of traffic lights is more difficult, mainly because of the higher requirements for breeding water quality and the special care requirements for larvae. Propagation water needs to use very soft distilled water, then use sodium dihydrogen phosphate to adjust the pH of the water to 5.6~6.5, and inflate it with a larger air pump for 2~3 days, and pour it into a large-mouth glass bottle for use. A layer of nylon mesh (the size of the mesh should not allow the brood to pass through) is laid on the bottom of a large-mouthed glass bottle (90 mm in diameter, 180 mm in height, and 130 mm in depth), and a little hair shrub is laid on the mesh plate and put into each bottle. A pair of broodstock. In order to increase production, usually 50 to 100 glass bottles are required in the hatchery.
In the evening, put a pair of brood fish into the glass bottle, and the paper is covered with paper to create a dimly lit environment. The eggs are usually laid on the second day and observed at about 10 o'clock in the morning. All broodstock that produce good eggs should be fished out immediately. Broodstock that have not laid eggs can remain in the bottle. If the broodstock is still not spawning on the third or fourth day, it should be removed. During the spawning, the broodstock must be stopped to avoid deterioration of the water quality. Bottles that have already laid eggs should be concentrated in one corner. At 9 to 10 o'clock in the evening, an egg-raising task is performed. The unfertilized white eggs in the bottle are all sucked out with straws. The fertilized eggs are concentrated in 30 cm X 25 cm X 25 cm. The fish tank is hatched, and the water used for the hatching tank is to concentrate the water in the inner upper layer of the spawning bottle. Since the propagation water of the traffic light is highly acidic soft water, the old water must be used as the hatching water, and the new water is not available. replace. 400 to 500 eggs are concentrated in each aquarium and larvae are hatched within 48 hours. The temperature of the water is always kept at 25 degrees. It is best to paste the paper around the cylinder to prevent the light from causing the larval deformity.
Due to the small larvae and the small amount of swimming, the food can be eaten by the mouth. After opening the bait, after the yolk gray water is sifted with a 200-mesh gauze, feed it dropwise with a straw, wait for a period of time, and when the larvae swim normally, feed the 150-mesh gauze mesh with the filtered egg yolk gray water. . Due to the slow growth of larvae, the consumption of egg yolk gray water takes longer than other small breeds. In addition, the water quality of larvae hatching is extremely soft, and the water temperature is completely different from the daily feeding water temperature. When the larvae grow to 5 mm, the water in the 50 cm X 40 cm X 40 cm aquarium has the same water temperature as the daily water. The larvae and the water are pooled together in the aquarium to slowly adapt the larvae to the daily water quality. At this time, the larvae can be fed with small fish worms. One to two oxytetracycline tablets can be dissolved in water to prevent bacterial infection. When the larvae have red and green color, they are transferred to a length of 80 cm or a length of 100 cm. The big aquarium feeds until it grows into an adult fish.

Containerized Oxygen Cylinder Filling System

ETR can combine all parts of the Oxygen Cylinder Filling System into a customized container, including air compressor, refrigerate air dryer, filters, buffer tanks, Oxygen Generator and oxygen booster and cylinder filling station. 

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 an oxygen booster,  the oxygen pressure can reached to 15Mpa and fill in cylinders.
