1. Nursery conditions (1) Mature pro-Bau: healthy individuals without injury, shell length more than 6 cm; gonads look very full, enveloping the vast majority of digestive glands, gonads protruding from the margin, due to full of sperm cells The end becomes pure garden. (2) pro-ba holding pool and young bait cultivation pool, to dark plastic sheeting. (3) Collector: It is mainly made of transparent organic glass, polyethylene plastic algae board and film. (4) Acquisition frame: It is made of reinforced steel, wrapped in thin film, or tied with fine bamboo. 2, the process of pro-Bao stocking?? artificially induced spawning ?? screening fertilized eggs? larvae collection and cultivation (sparsely divided up in time)? For abalone breeding, bait is particularly important and must be prepared in advance. The larvae must be pre-attached with benthic diatoms or placed in a thin flat culture pond for several days before the larvae are collected, and then these adherent diatoms and unit cells are added. The algae harvester was moved into a larval culture pond to collect larvae later in the pan. In the process of raising abalone, algae cultivation should be continuously strengthened. In addition to adding proper amount of nutrients in the larval culture pond, light is also enhanced to promote the reproduction rate of benthic diatoms, and the breeding population of benthic diatoms and the feeding of larvae or juvenile abalone. The balance is maintained. For this reason, fertilizers need to be added continuously. If the food is basically insufficient, replacement foods or bait plates should be added after changing the water to meet the larvae's intake. 3. Disease prevention and control of solitary diseases: Disease: The epithelial tissue of abalone is removed and the affected individuals are inactive. Severe illness mechanical stimulation does not respond. There are active bacteria in the blood, the body fades, the tentacles are weak, the visceral mass shrinks, the feet retract, and the abalone undergoes permanent death from metamorphosis to 1 cm, sometimes with a peak of death. Pathogens: The red abalone is prone to gonorrhea in young hours, and the biochemical characteristics of isolated solitary bacteria are close to that of alginic acid solitary bacteria. Time: Ordinary hyperthermia or hyperoxic proneness. Prevention: Prevention: young abalone should be cultured in a suitable environment, the abalone can be used to dip drug wounds. Treatment: 1) Immersion with chloramphenicol 25-50 ppm sea water for 0.5-1 hour, or dip with 1% solution of sulfamethoxazole in sea water for 5 minutes. 2) Rub the wound with chloramphenicol or sulfamethoxazole formulated in 5% sea water. The above-mentioned drug treatment methods all require the abalone to be placed in the air for 10-15 minutes so that the liquid can fully infiltrate the lesion and be returned to seawater for rearing. If necessary, repeat the treatment on the second day.
