1, feeding method must master "four set"
(1) timing: with the bait to follow the system, feed every day from 8 to 9 o'clock, the water temperature is low or rainy days, postponed feeding 1 to 2 hours, the water temperature above 30 °C, feed 1 to 2 hours earlier .
(2) Positioning: The bait should be fed on the food table. The food table is suspended with a rope and is 2 cm above the water surface in order to observe the feeding situation and reduce the loss of bait. Fresh bait is put on the food market.
(3) qualitative: with the bait to be free from moisture, deterioration. Fishmeal requires yellow color, good taste, fine powder, protein content higher than 60%, and fat content lower than 8%. Barium-starch has a strong viscosity. Fresh bait should be fresh and clean.
(4) Quantitative: According to the eating conditions and the water temperature, generally at the water temperature of 25°C, the daily feed is 2% to 3% of the carp body weight and the fresh bait is 5% to 10%. Water temperature below 25 °C or higher than 30 °C, feeding should be appropriately reduced. Usually mastered within 1 hour after eating.
2, adjust the water quality, to prevent the method of adjusting the water quality of dead fish, can take microcystin culture, use of oxygen and water change.
(1) Microcystis spp. grows in a large amount in the rearing ponds: through photosynthesis, dissolved oxygen is increased in the pool water to stabilize the water quality. Microcystis absorbs the toxic substances such as ammonia and other toxic substances produced in the pool water and decomposes the residual baits. Purification, at the same time, Microcystis multiplied, the pool water became thicker, the transparency became lower, and the underlying light of the pool water was dark, which was the favorite living environment of the carp.
(2) Method for culturing Microcystis:
1 Introduction: The microcystin algae species were introduced into Dianchi Lake. At the same time, urea or ammonium sulfate was applied to Dianchi Lake. The amount of urea or ammonium sulphate was 1 to 2 kilograms per acre, which was propagated in a few days. The water was thick blue-green, and the water quality was about 20 cm. the best. If the water becomes light or yellow, and the transparency is above 25 cm, it means that the fertilizer in the water is insufficient, and immediately applying topdressing urea. After two or three days, the water color turns dark green. If the transparency is less than 15 cm, it indicates that the microcystin is too much, and a lot of water should be changed to make the water transparency about 20 centimeters. Microcystis lumps floating on the surface of the water, the water becomes black, you need to change the water and re-introduce the algae. It was found that there were a large number of rotifers or blisters in the pond that harmed Microcystis and the crystals were splashed with crystal trichlorfon to make the pool water 0.5 to 0.7 mg/l.
2 pool to install waterwheel aerator: 3 to 4 times a day boot, usually midnight to dawn before starting 2 to 3 hours, at noon to boot 1 to 2 hours before feeding half an hour to increase the appetite of eels. In case of rainy and hot days, you have to extend the boot time. During the high season of growing squid, the fish density is high and it is necessary to turn on the whole night.
3 timely change of water: early spring and late fall water temperature is low, every 3 to 5 days to replace some of the pool water, high summer water temperature, need to replace some of the pool water every day. If the water quality in the Dianchi Lake is too strong, the dissolved oxygen content drops, and the ammonia nitrogen and nitrous oxide nitrogen concentrations are high, indicating that the water quality has become contaminated, the food intake of the carp decreased, and even the floating head died. In this case, the pool water should be replaced in time.
Feeds fed into clams are fresh feeds such as cockroaches, cocoons, cockroaches, snails, clams, small junk fish, etc., and compound feeds. They are composed of fish meal, silkworm cocoon powder, miscellaneous fish, clam-starch and additives, and fish oil. More than 45%.
