Problems solved by technology

Daisen preparations have played a key role in the control of ciliates for a period of time, but in the past two years, their shortcomings have become increasingly exposed, such as causing hypoxia in farmed animals
Because it cannot meet the needs of modern farming, it has gradually withdrawn from the fishery medicine market

Embodiment 1

[0033] Embodiment 1 A kind of method of controlling shrimp ciliate disease

[0034] Step 1, drying

[0035] After the prawn cultivation is completed this year, the water in the shrimp pond is pumped out, and the silt is dried for 5 days to make fine cracks appear in the silt.

[0036] Step two, decomposing

[0037] After the drying is completed, stir the decomposing initiator evenly, add 2000kg of water according to the amount per mu to prepare the decomposed material and mix it evenly, and then evenly sprinkle it on the surface of the sludge. After the decomposed material penetrates into the sludge, attach a non-woven fabric on the top of the sludge; The cloth can provide more nutrients and breeding places for different strains; after 1-2 days, cover the non-woven fabric with a black plastic film; the periphery of the black plastic film in the shrimp pond is compacted with shrimp pond mud; the black plastic film can absorb More heat can greatly improve the activity of bacte...

Embodiment 2

[0052] Embodiment 2 A kind of method of controlling shrimp ciliate disease

[0053] Step 1, drying

[0054] After the prawn breeding is completed this year, the water in the shrimp pond is pumped out, and the mud is dried for 6 days to make fine cracks appear in the mud.

[0055] Step two, decomposing

[0056] After drying, stir the decomposing initiator evenly, add 2600kg of water per acre to prepare decomposed materials, mix them evenly, and evenly sprinkle them on the surface of the sludge. After the decomposed materials penetrate into the sludge, attach non-woven fabrics on the top of the sludge; The cloth can provide more nutrients and breeding places for different strains; after 1-2 days, cover the non-woven fabric with a black plastic film; the periphery of the black plastic film in the shrimp pond is compacted with shrimp pond mud; the black plastic film can absorb More heat can greatly improve the activity of bacteria;

Embodiment 3

[0071] Embodiment 3 A kind of method of controlling shrimp ciliate disease

[0072] Step 1, drying

[0073] After the prawn breeding is completed this year, the water in the shrimp pond is pumped out with a water pump, and the mud is dried for 7 days to make fine cracks appear in the mud.

[0074] Step two, decomposing

[0075] After drying, stir the decomposing initiator evenly, add 3000kg of water per acre to prepare decomposed materials, mix them evenly, and evenly sprinkle them on the surface of the sludge. After the decomposed materials penetrate into the sludge, attach non-woven fabrics on the top of the sludge; The cloth can provide more nutrients and breeding places for different strains; after 1-2 days, cover the non-woven fabric with a black plastic film; the periphery of the black plastic film in the shrimp pond is compacted with shrimp pond mud; the black plastic film can absorb More heat can greatly improve the activity of bacteria;

Abstract

The invention provides a prawn ciliate disease control method. The method is characterized by comprising a water pumping step, wherein the water pumping step is as follows: removing water in a prawn pond by means of a water pump, and performing airing on silt for 5-7 days to ensure that micro cracks occur on the silt. When the micro cracks occur on the silt after the airing step, multiple microorganisms are accumulated around the cracks, and meanwhile, comfortable propagation spaces and locations are provided for the movement of the microorganisms, thereby greatly increasing the quantity of living bacteria, and laying a foundation for a subsequent decomposing step. Through a fermentation step in the invention, the clearance rate of ciliates and ciliate ova basically reaches 100%; at the earlier stage of prawn culture, the use of a disinfectant is avoided, thereby being beneficial to the growth of young prawns, and reducing water body pollution; and meanwhile, the special culture of algal facies in the prawn pond at the later period is avoided.

Description

technical field [0001] The invention relates to a method for preventing and treating the ciliate disease of prawns. Background technique [0002] At present, in the process of shrimp farming, the incidence of ciliates is relatively high. Ciliates can parasitize the whole body of river crabs and shrimps, and attach to ciliates in sludge. Shrimp and crabs are covered with ciliates all over their bodies, their mouthparts cannot open their mouths, and their eyes cannot stretch and rotate. Finally, they are starved to death or exhausted, resulting in low survival rate of shrimp seedlings. At present, the principle of "adjusting water first and then killing insects" is generally followed in the ordinary treatment of prawn ciliates. [0003] At present, there are mainly the following methods: [0004] 1. Zinc sulfate, copper sulfate and their compound preparations: Zinc sulfate, copper sulfate and their compound preparations, as a heavy metal salt insecticide, have been used for ...
