1. Site and equipment: The culture of bamboo shoot shell fish is generally carried out in a large area, and a relatively large culture pond is needed. The area is generally about 4 mu, which is more appropriate.The bottom of the pond needs some silt, because the bamboo shell fish like to move around the silt on the bottom of the water.Some nets can be arranged at the water inlet and the water outlet, which can effectively prevent the bamboo shell fish from escaping.Before putting in the bamboo shell fish, the pond needs to be thoroughly disinfected.
2. Selection of fry: It is best to choose a bamboo shell fish with a body length of about 10 cm, uniform size and health.Generally speaking, the number can be controlled at about 3500.
3. Feeding: Regular feeding is also a very important task.When the bamboo shell fish is in the fry stage, they can eat rotifers or cut into small pieces of fish; When the bamboo shell fish reaches the adult stage, they can eat various aquatic insects and fish.
4. Water temperature: Generally speaking, water temperature above 22 degrees is the best.If it is below 22 degrees, the appetite of bamboo shell fish will be affected.The lowest temperature can not be lower than 18 degrees, if the temperature is lower, the bamboo shell fish will not eat.
5. Change water: It is also very important to ensure the water quality. Generally speaking, it is necessary to change new water every half a month or so.In addition, it has to be disinfected every one and a half months.
6. Disease prevention: Some diseases are relatively common, such as "red skin disease". Appropriate amount of drugs can be mixed into the feed to prevent these diseases.
1. Selection of parent fish: It is necessary to select sexually mature and large female and male bamboo shoot shell fish, and the ratio should be controlled at 1:1.
2. Artificial aphrodisiac: In order to make the reproduction more efficient, you can use some oxytocin for them in the process of artificial aphrodisiac. The effect of an injection of oxytocin is generally about one and a half days.After the injection, the male and female squid can be placed in the spawning pool.
3. Natural spawning: In the spawning pond, the parent fish can complete the process of spawning and fertilization.At the bottom of the pond, you need to set up some egg nests so that fertilized eggs can attach to them.
4, artificial incubation: These fertilized eggs can be artificially hatched, so the probability of hatching out is relatively large.When hatching, the water temperature should be between 27 and 32 degrees.At the same time, it is necessary to ensure that there is a certain degree of water flow.
