Abalone is a kind of seafood and mollusk, which has been listed as the "top of eight treasures" since ancient times. The dishes made with it are delicious and mouth-watering. Its shell has a wide range of uses, not only can be made into valuable handicrafts, but also has certain medical value. Abalone is divided into two parts, shell and soft. In the past, it could only be collected naturally, but now it can be cultivated artificially. Breeding and seedling raising are very important in artificial breeding. (1) intensive culture and selection of parent abalone. The economic abalone in China includes ear abalone, sheep abalone, variegated abalone and wrinkled abalone. From a large number of adult abalone, individuals with strong growth of more than 2 inches were selected as new abalone, and intensive culture began from March to May. Intensive farming can be carried out in ponds in the sea area. The container is made of plastic and bamboo baskets, and a proper amount of female abalone is put in. Hang it at a depth of about 1.5-2 meters from the water surface and feed it every 3-4 days 1 time. The amount of bait should not be too much, the oxygen content in the water should be sufficient, and the gonad development should be checked at any time. Before sexual development is mature, male and female should be raised separately in time, and the new abalone hanging in the sea area should be transferred to the pond for culture. The parent abalone is required to grow healthily (the shell length is more than 6 cm), and the gonad is full, protruding from the shell edge and dull in shape. (2) induced labor. The parent abalone is put into an incubator filled with filtered seawater according to the sex ratio of 2∶ 1-3∶ 1. First, slowly inject seawater of about 70℃ into the water tank to raise the water temperature by 2℃-3℃. After about 20 minutes, inject low-temperature seawater to reduce the water temperature by 4℃-6℃. At the same time, aeration can increase the oxygen content in water and obtain good oxytocin benefits. Or put the parent abalone in the dew in a humid place for 0.5- 1 hour, then put it into the spawning box according to the male-female ratio of 3: 1, and introduce fresh seawater to keep the seawater circulation in the box. Sperm eggs can be discharged after 1-2 hours. (3) fertilized egg treatment. After the fertilized egg sinks into the water body, the upper seawater is removed and filtered seawater is introduced; Or collect the fertilized eggs in another box with filtered seawater. Hermaphroditic parent abalone 1 box lays eggs, and generally washes eggs every 1 hour/time; If amphipathic abalone lays eggs alone, the number of egg washing can be reduced accordingly. (4) Collection of planktonic larvae. The newly hatched trochophore only swims by the water. After about half an hour, you start swimming in the upper layer of the incubator. At this time, you can collect (siphon with a rubber tube in a nursery filled with fresh filtered seawater in advance). 5] Preparation and delivery of collector. The heat collector can be made of plexiglass, polyethylene plastic sheets and films, and there are two types: frame type and free type. The frame size is 20×50×40 cm, and each long side is penetrated into a pair of plastic ropes at equal intervals (2-3 cm), and polyethylene films are sandwiched at a certain angle, with 20-25 pieces for each frame; Freestyle is to make a grid with a plastic pipe wrapped in iron wire, and then stick a piece of polyethylene film on the bar. Tie a stone to the center of the whole membrane and sink it into the pool. The periphery of the membrane can be opened freely. 4-6 days before artificial spawning, the egg collector should be put into the pond, so that a layer of benthic diatom can be attached to the egg collector for the larvae to eat, and it is appropriate to use an egg collector with an attachment area of about 20 square meters per cubic meter of water. (6) Feeding and management of reptile larvae. After the larvae attach themselves, they begin to breed in running water. Spray water into the pool to increase dissolved oxygen in the water; After the larvae attach themselves, they begin to lick all kinds of algae. Algae can be cultivated artificially outdoors. When the attached diatoms are not enough for larvae to eat, the old and new bait plates can be stacked and moved to the new bait plate. When the first breathing hole appears, large algae (such as tiger platform, Ulva, etc. ) should be fed once, and cultured for 3-4 months after entering the juvenile stage, and then moved to the selected sea area or artificial pond for culture.
