Freshwater white squid water feeding for 20 days, a total length of about 3 cm, called summer fish species. According to the author's more than two years of seed cultivation experience summarized as follows for your reference.
1. The choice of ponds is rich in water resources, good water quality, no pollution, good lighting in ponds, convenient drainage and drainage, a length to width ratio of 3:2, a pond size of 2 to 35 mu, a pool depth of 2 meters, and a bottom soil of loam. . In addition, there is aeration facility.
Second, Chizi clear pool repair: the pool gate should be solid, the old pool out of the pool at the end of too much mud, and to maintain a 5-10 cm thick mud, is conducive to the cultivation of food organisms.
Pond disinfection: 50-60 kg of lime per acre dry pond, sunny at noon Quanchiposa, 7-10 days after the vote seedlings, or with 20 g / cubic meter bleach Quanchiposa, 3-4 days after the vote seedlings.
Third, the stocking density of 300,000 to 400,000 acre stockings. In order to be safe, let's put some test fish on the day before the seedlings are released, and let them be released after the drug toxicity in the water is determined to have completely disappeared. When watering, the seedlings are refreshed and the transparency is controlled at 40-50 cm to prevent the large mink in the pool from stabbing the fry. Before releasing the seedlings, ensure that there is fine weather within a few days, which has a considerable impact on the survival rate of the seedlings. When investing seedlings, select sunny days from 7:00 am to 8:00 pm, and pay attention to the temperature difference before and after, first place the oxygenated nylon bag in water for 30 minutes, and when the seedlings fall down, lift the water surface first, then pull back. Bag angle, so that the fish in the water evenly, not sinking.
Fourth, the daily management of feeding technology: put 3-4 hours after the seedlings, you can start feeding, every 100,000 fry daily feeding 6 egg yolks and 250 grams of young dip material, egg yolk through the 40-mesh gauze filter; Generally 5-6 times daily feeding. During the feeding period, evenly spilled along the edge of the pool, requiring less time; after 10 days, it was changed to soymilk feeding, the amount of feeding was more appropriate, and the daily feeding amount was adjusted every five days. In addition, the weather, water temperature, and water quality were also used. Make discretionary additions and deletions.
Water level control: The water level at the beginning is 50 cm deep, and water is added 20-30 centimeters every 5-6 days until it is 15 meters deep.
Xuntang: 3 times a day on a patrol pool, once in the morning, middle and evening, check whether there are frog eggs and sundries in the poolside in the morning, remove and observe the floating head in time, and use it as a basis for feeding amount and adding water; Oxygen machine 1-2 hours; early evening observe if there is a fish disease symptoms.
Pull nets to exercise: fry cultivation 20 days, before leaving the pool to pull the net to exercise 2-3 times. Select the sunny hours from 9 to 10 o'clock in the morning. When the first time the network is set up, the action should be light and fast; after the second to third time, the network time should be extended appropriately. Its purpose is to enhance fish body constitution.
