First, cage settings. The use of polyethylene no summer flowers mesh, mesh 36, made of 20-30 square meters of rectangular cages, specifications for 8 meters x 3 meters x 1.2 meters or 10 meters x 3 meters x 1.5 meters. The cage is open type, and the port is made of mesh to prevent escape. The cage is set in a fish pond with a water depth of 1.5 meters or more. The transparency of the pool is 25-30 cm. The cages were placed in the pond 7-10 days before the arrival of the scutellaria baicalensis. The bottom of the tank was 0.5 meters above the bottom of the tank, and the tank mouth was 0.4 meters above the water surface. The cage area accounts for about 1/10 of the pond area.
The center of cages shall be used to store water-borne peanuts that account for 80-9Q% of the cages' space, for the inhabitants of the yellow pelican to inhabit. Otherwise, the pupae will entangle each other, become ill and die in large numbers. The cage should also be stocked with 3-5 kilograms of loach, and they can be moved up and down to prevent them from intertwining.
Second, launch the picnic. Wild jaundice is harvested through various methods such as cage trapping, hand-catching, and fishing. The jaundice is subject to various degrees of damage, and yellow fins with serious injuries cannot be raised temporarily. Astragalus in the box before entering the 3-4% of salt water and soak for 5-10 minutes (who are desperate for the outsider and lying pelvic floor should not be raised), per square meter cage put 1.5-2 kg specifications for the weight of more than 50 grams of Astragalus seedling.
Third, feeding and management
1. The feed is mainly feedstuffs such as alfalfa, fly maggots, snail meat and small trash fish, animal viscera, etc., supplemented with wheat flour, corn flour, bean cake, etc., and a small amount of leaves and trace elements. Mixing methods: mainly with fresh live products with the right amount of wheat flour, jade powder, a small amount of leaves, minerals and vitamins; carnivorous fish feed 65%, fresh live animals 35%, plus a small amount of leaves. All of the above are made into strips of bait, that is, the bulk of the feed minced, and mix the other components into a dough shape, and the minced meat machine pressed into strips of 3-4 mm in diameter and 3-4 cm in length. Air dried can be fed.
The seedlings have been fed into the box 3 without feeding. After that, they are baited with oysters, snail meat, etc. The feed rate (ie, the daily feed rate is 100% of the total weight) is 1-2%. After the food is eaten normally, it is gradually mixed with wheat flour or with matching materials to reduce costs. When the water temperature is 20-28 degrees Celsius, the maximum amount of feed is the largest, and the live animals are the main ones. The feed rate is 5-8%. If the feed is predominant, the feed rate is 2-3%; the other seasons are the same. It is 3-4% and 1-2% respectively. The bait is spotted on the food table to observe the eating wish. The food table is made of wood strips and mesh cloth, with a specification of 0.6 m x 0.4 m x 0.1 m, fixed at a depth of 20 cm below the water surface. Huang Hao mostly foraging at night, early in the evening feeding, then gradually advance to 5 pm. During the growing season, the feed was fed at 9am.
2, disease prevention. Found that the disease was removed in time. Sprinkle once per day with potassium permanganate solution in the cage to make the water pink. Every 10-15 days, use bleaching powder to hang bags once, and each bag contains 100 grams of bleaching powder. Hang 2-3 bags per box to disinfect and sterilize the pool water.
Adding low concentrations of oxytetracycline to the strips of bait and adding 50 mg of oxytetracycline per kilogram of wolfberry daily can promote growth and reduce disease. Clean the cage once a month, and adjust the density according to the size of the bin.
3, control the desire to harm. Rats are the biggest enemy of raising cages in cages. They often break their cages and allow them to escape. Some bunches of long hair can be placed around the cage to scare the rats. The effect is quite good.
