Abalone breeding techniques

Abalone is a kind of seafood and mollusk. Since ancient times, it has been listed as "the head of Bazhen." The dishes made with it are delicious and mouth-watering. Its shell is very versatile, not only can be made of expensive handicrafts, but also has some medical value. Bao is divided into two parts, shells and soft bodies. In the past, it only depended on natural harvesting. It can now be cultivated artificially. Breeding and nursery are very important in artificial breeding. (1) Intensive breeding and selection of pro-Bao. China's economical abundance includes ear abalone, sheep abalone, variegated abalone and abalone abalone. It is possible to select from a large number of successful abalone individuals that grow to be more than 2 inches in size as new abalone, and begin intensive culture in March and May. Intensive breeding can be done in the pool in the sea area. Containers are made of plastic and bamboo baskets. Proper amounts of abalone are put into the cage, and they are raised about 1.5 to 2 meters deep from the surface of the water. The bait is fed once every 3 to 4 days. The amount should not be too much, the oxygen content in the water should be sufficient, and check the gonadal development status at any time. Before sexual maturity, males and females should be reared in a timely manner, and the new abalone bred in the sea area should be fed into the pond. It is required that the pro-abalone grow in a healthy shape (the shell length is more than 6 cm), the gonads are plump, protrude from the rim of the shell, and the shape is obtuse. (2) Induction of labor. The ratio of male to female in the ratio of 2:1-3:1 was placed in the incubator with filtered seawater. Start pouring seawater at about 70°C slowly into the tank to increase the water temperature by 2°C to -3°C. After about 20 minutes, input low-temperature seawater to reduce the water temperature by 4°C to -6°C. At the same time, inflate and increase oxygen content in the water. Amount, can get a good mobilization efficiency. Or pro-Baluo dry in the wet place 0.5-1 hours, and then according to the ratio of 3:1 male and female into the spawning box, and import fresh sea water, keep the sea water circulating inside the box. After 1-2 hours, the eggs can be released. (3) Fertilized egg treatment. After the fertilized egg sinks into the body of water, the seawater in the upper layer is excluded, and filtered seawater is introduced; or the fertilized egg can be collected in another box filled with filtered seawater. Both genders spawned and spawned in 1 box, generally changing the water and washing eggs once every 1 hour; if both sexes spawned and spawned respectively, the number of washings could be reduced accordingly. (4) Collection of planktonic larvae. The newly hatched larvae larvae swim only in the near water. About half an hour later, they begin to swim in the upper and upper chambers of the incubator. At this time, they can be collected (collected in a nursery pond pre-injected with fresh filtered seawater using a rubber tube). . (5) Collector preparation and delivery. The collector can be made of plexiglass, polyethylene plastic sheet and film, both shelf type and free type. The rack size is 205040 cm. The plastic string is equidistant (2-3 cm) on each long side, and the polyethylene film is sandwiched at an angle of 20-25 pieces per shelf. The free style is Wrought metal boxes are made of iron wire wrapped in plastic pipes, and then a thin polyethylene film is attached to the bars. The entire center of the film is tied with stones and sank into the pool, and the film can be spread around. The collector is placed in the tank 4 to 6 days before the artificial production to attach a layer of benthic diatom on the collector for the larvae to be collected, and the collection area of ​​about 20 square meters per cubic meter of water is put in. Appropriate. (6) Feeding management of larvae. When the larvae are attached, flow-through cultivation begins. Water is sprayed into the basin to increase the amount of dissolved oxygen in the water. After the larvae are attached, they start to feed various algae. Algae can be cultured outdoors. When the attached diatom is not enough for the larvae to eat, new and old bait plates can be used to allow them to migrate to the new bait plate. When the first breathing hole emerges, a large seaweed (such as oysters, sarcophagus, etc.) is to be fed into the young larvae and then reared to the selected sea area or artificial pool for feeding for 3-4 months.

Puffed Corn Flour

Puffed corn flour is a type of flour made from corn that has been puffed or expanded through a process of heat and pressure. The process involves heating the corn kernels until they become soft and moist, and then rapidly releasing the pressure, causing the kernels to puff up. The puffed corn is then ground into a fine flour that can be used in a variety of recipes. Puffed corn flour is often used as a gluten-free alternative to wheat flour in baking and cooking, and is also used in snack foods such as popcorn and corn chips. It is high in fiber and protein, and has a light, airy texture that makes it ideal for use in baked goods.
