First, materials and methods
1. The broodstock chose the broodstock that had been spawned in the spring and summer of the year and had an individual of more than 400 grams.
2. Broodstock Breeding In order to reproduce again in autumn in Pengze squid which has already laid eggs in spring and summer, broodstock must be cultivated in summer.
1 The broodstock area is generally 2-3 mu per pond and the water depth is 1.5-2m.
2 stocking density 300-400kg/mu.
3 Baits are fed with artificial diets with a protein content of about 30%. The daily amount of bait is about 3% to 5% of the fish's body weight depending on the fish's feeding condition.
3. Artificial priming Peng Zexi can lay eggs on her own in the autumn, but it cannot be synchronized. To obtain large quantities of autumn larvae of squid, artificial oxytocin must be used.
1 Peng Zeyu's autumn breeding time, in the late September to mid-October in the southern Anhui region, the water temperature does not exceed 30°C.
2 Artificial urine production Determine the number of broodstock broodstock based on the number of fry, which is generally calculated as 1-20000 fish hatching per female. The selected broodstock is injected with LRH-A + DOM, and the ratio of male fish is 2:1, preferably 1:1. Put the injected broodstock back into the original pond or another pond with an area of ​​1000 to 2,000 m2 as the spawning pond.
3 Spawning Fish nests are hung around the spawning pool and fish nests are promptly exchanged according to spawning of the broodstock to avoid excessive density of eggs. The spawning pool preferably has micro-flowing water.
4.Fry fry 1After autumn, the water temperature is higher. The eel eggs can be directly hung in the fry pool. The area of ​​each fry is generally 1000-2000m2, the water depth is about 1m, and the stocking density is controlled between 500,000 and 1 million. The pond must pass through. Clean ponds should be filled with fresh water to prevent wild fish from mixing into the hatchery.
2 When the water temperature is between 27°C and 28°C, hatched fry can be fed with soya milk or fish for sale on the third day.
Second, the results of the injection of oxytocin Pengze bred broodstock into the pool to natural spawning fertilization. In general, a small amount of broodstock laid eggs in the early morning of the second day after the injection of oxytocic agents, and a large number of broodstock laid eggs in the third and fourth days, and the fertilization rate reached over 85%. The hatching rate of the fry in the large pool reached more than 90%. .
Third, the summary
1. Carp is spawning fish many times a year. Pengze squid, which has already laid eggs in spring and summer, has been intensively cultivated and will be breeding again in the fall.
2. A large number of squid after injection of oxytocic acid are placed on a large pool of 1-3 mu, keeping the micro-flowing water, and spawning eggs can be synchronised within 3 to 5 days and the fertilization rate is high. This approach can also be adopted in the spring to obtain a large number of salmon fertilized eggs.
3. Fertilized eggs hatch naturally in Dachi, simple and convenient, and the hatching rate is relatively high. It can also be cultivated and sold according to the needs of farmers.
4. In the spring of the second year, the eel fry which was propagated in the autumn has become a larger-sized finger of 3-5cm in length. The market is optimistic and easy to obtain better economic benefits. Xu Xianming
Sawa Sakura's artificial propagation in autumn [Salmonidae]
Carp is a traditional cultured species in Zhangzhou, Fujian Province, especially in recent years. It has been cultivated in Pengze. The breeding cycle has been shortened from the previous year and a half to two years to the current year. One of the main measures is to put the seedlings that were propagated in the early spring or the wintering species that are breeding in the fall. Therefore, in addition to the need for early spring seedlings, the farmers also need the salmon seedlings to be propagated in autumn. In order to meet the needs of production, in recent years, in addition to grasping young seedlings in early spring, Pengze’s artificial propagation has also been carried out in autumn, and large quantities of fry have been obtained. The main techniques are summarized as follows:
