First, the choice of intimacy and inducing spawning The pro-abalone used in artificial breeding seedlings should be selected to be healthy and non-destructive, physical and fat, foot activity, agile, obvious male and female gland individuals, the size of more than 5 cm, pool water temperature remained at 24-30 °C, pH 8.0-8.2, specific gravity 1.022-1.08. Every morning and evening, change the water with filtered seawater or precipitated seawater once. You should give pro-Bao to feed algae such as kelp and stone bream. After 120-140 days of incubation, the pro-Bun will reach sexual maturity. Mature female gonads are brown-green, and males are orange-yellow. After pro-Bao maturation, spawning can be done sparingly, allowing natural discharge, and artificial induction methods are generally used in production.
The method of inducing spawning and spawning sperm for spawning includes temperature-stimulating stimulation method, shade induction method, ultraviolet irradiation method and seawater induction method. One UV irradiation method is to put a UV lamp on a sink for production. The size of the sink is 78 cm, 55 cm, and 40 cm. The tank is equipped with 50 cm deep filtered seawater. The lamp is 10-15 cm away from the water. Put 20 to 40 pro-bowls per tank, turn on the light for 3-5 hours at water temperature of 20-26°C, pro-Bao will spawn and ejaculate. After pro-batch production and production of eggs, the egg and sperm can be mixed in the egg collection tank for artificial insemination, and the sperm concentration is controlled at about 1 million per ml.
Second, hatching fertilized eggs can be directly in the ovulation tank for hydrostatic incubation. The fertilized eggs have a scale of about 500 centimeters per square centimeter. When the water temperature is 24-25°C, the larvae emerge from the film after 8 hours, and grow into larvae in about two days. When the larvae enter the flood season, the harvester can be used to put the seedlings into the cultivation pond.
III. Seedling Culture After the embryos of abalone enter the late stage and grow into platter larvae, healthy larvae should be collected and transferred to the culture pool to start cub breeding. When the larvae enter into a stable attachment life, they should change water by 1/2 per day, the water temperature should be controlled at 20-24°C, and the aeration volume per minute should be 1%-1.5% of the cultivated water body.
Fourth, the raising and management of young Bao.
1. Stocking density. Irrespective of the method adopted, the stocking densities of the juvenile abalone should not be too large, otherwise it will affect the survival rate and growth rate. Using cage culture, about 6,000 juvenile abalone with a shell length of 5 mm can be stocked per square meter of water. The use of four-foot brick culture, the area of ​​the bottom of the pool can be used to store the shell length of 5 mm of juvenile abalone 4000, or the breeding of shell length 10-20 mm of juvenile abalone 2000-3000 grains.
2. Inflatable water. The amount of water changed can directly affect the feeding, growth and survival rate of the young abalone. Under normal circumstances, with the increase of the amount of water exchange, the average growth rate of the young fishes also increases. In order for the dissolved oxygen in the water to be not less than 5 ml/l, the daily water flow should not be less than 4 times the incubation water body before the average shell length of the young larvae is 6 mm, and should not be less than 6 times more than 6 mm.
3. Feed input. During the hatchery period, young leafy green algae or red algae can be fed. Juvenile abalone's feeding artificial diets have a faster growth rate than feeding foods. They can reach larger specifications before winter and increase the survival rate of overwintering. The daily feed amount of synthetic feed was 3%-5% of the weight of the juvenile abalone.

Electric Heating Cape is quite similar to Electric Over Blanket. Their main difference is the shape. Heating cape is more like a clothes.
People can wear it during a cold night, and choosing the suitable heat setting to keep warm, as it has adjustable 4 temperature settings.
Heating cape is also not suggested to be used during sleeping.
It also has the function of automatic shut off, normally it is set up by 2 hours, which is approved to be the best for human health.
