Fowl breeding technology

Fodder cultivation methods The cultivation methods of hijiki are the same as those for seaweed. Therefore, the production and setting of farmed dumplings can imitate the production of sea bream.
The cultured water layer, with the experience of trial farming, grows fastest on the surface. Hanging rope pitch is suitable for 30-40 cm, usually 3-5 cm clip a seedling. In the early stage of hanging up, you can also hang a bit more closely, and then adjust along with the growth of the algae.
Selection of breeding sea area
1) The sea area where the water quality is more fat, less rough, smooth, and well-lit.
2) The water depth of 2 meters or more is appropriate, too shallow, algae for easy and seabed friction. The sandy bottom is better for the bottom layer, which is more convenient for piling.
3) There should be no large quantities of freshwater or toxic substances in the cultured sea area so as not to affect the growth of the algae.
The algae seedlings harvested by the method of cutting seedlings must be seeded and maintained immediately. If it is too late to catch the seedlings, they must be raised in seawater, and should not be piled together or raised with a small amount of seawater. Clipping rope can be used as a brown rope and polyethylene rope of φ6, etc. The length is different due to the difference in the way of flat raising or feeding and the degree of transparency of cultured sea areas, which is generally about 1-2 meters.
It is very fragile and tender, and it is easy to break. It should be noted that when the seedlings are caught, the initial experience and the yield of the nests are high. When the seedlings were selected, the length of the algae was almost the same as that of a rope. The cluster spacing was 3-5 cm apart and 3-4 were clustered. In addition, single clips could also be used. The ungulate is a species that grows at the top. Any part of the algae can be grown on the seedling rope, but the root is exposed outside the rope. The clips should not be overtightened to avoid pinching the algae and causing rot to fall off. Although algae seedlings have a strong ability to resist drying, they also need to shorten the time in the air as much as possible to avoid over-drying and affect the health of the larvae. After the seedlings are caught, they must be kept immediately and they are too late to hang up. At the time, it needs to be raised in seawater.
Management during aquaculture (1) Frequently the sea is inspected for the growth and development of Sargassum. If it is found that the seedlings are shed, they must be filled at any time. It is even more urgent to tidy the rafts and ropes in order to prevent them from being damaged by storms.
(2) The floating mud deposited on the algae body and the attachments such as the mixed algae are often washed, so as not to affect the normal growth of the hijiki.
(3) Adjust the water layer timely so that the algae body can obtain the most suitable living conditions in different stages of growth, allowing it to fully grow and increase its yield.
