Description
Technical Field
The invention belongs to the field of aquatic products, and particularly relates to a method for effectively preventing and treating taura syndrome in the culture of salt pan shrimps.
Background
Taura syndrome, commonly known as "red tail disease", is a severe infectious prawn disease caused by Taura Syndrome Virus (TSV), with shrimp bodies becoming red and soft-shelled during acute infection and irregular blackening of the keratinized epithelium during transitional infection. The animal epidemic notification directory of 2019 version is officially effective in 2019, 1 month and 1 day of 2019, in the world animal health Organization (OIE). One of the 9 crustacean diseases reported by OIE is Taglar syndrome. The taura syndrome mainly occurs in the molting stage of prawns, the prawns do not eat food, the water surface slowly swims, the bodies of sick prawns are weak, red pigmentation exists in gastropods, sometimes the whole bodies of the prawns become red, and necrosis focuses appear on individual parts of the bodies of the prawns. The mortality rate is more than 95%.
At present, no effective treatment measures are available for the taura syndrome of prawns in the outbreak stage, so that the prevention and control can be only adopted in the breeding process. However, single prevention and control is often ineffective.
Disclosure of Invention
In order to solve the problems, the invention provides a method for effectively preventing and treating taura syndrome in the culture of salt pan shrimps, which comprises the following steps:
1. big change, shallow change and deep change: most of the primary evaporation ponds of the seawater salt field are 1000-5000 mu, and the water level is 50-60 cm. The water body is large, which is not beneficial to artificial regulation and control; the water body is shallow, which is not beneficial to the prawn to avoid the adverse weather and the enemy. Transformed into a single 100-500 mu water level of 120-150 cm. And (3) arranging ring ditches outside 10-20 meters of the four side slopes, wherein the width of each ring ditch is 20-30 meters, and the depth of each ring ditch is 40-60 cm.
2. Trimming the pond: in non-production seasons, draining water, using 50-200 kg of quicklime per mu, properly using multiple purposes at low-lying positions, mechanically ploughing for 20-30 cm, and airing for more than 30 days.
3. Selecting stress-resistant varieties: selecting excellent varieties which are bred by focusing on stress resistance characters. The species with the growth speed is emphasized, so that the disease prevention and control difficulty of the salt pan shrimp culture mode is increased.
4. Detecting the taura virus: the germplasm, the larvae and the seedlings are selected, the detection report of the taura virus is checked, and all links are negative and can be used as the seedlings for the culture of the shrimps in the salt pan.
5. And (3) marking the shrimp larvae to be coarsely salted: the salinity of qualified P5 shrimps in life is gradually increased from 25 per mill to 40 per mill to 65 per mill to adapt to the culture environment of a salt pan, water is changed once every 2 days after the qualified P5 shrimps are stabilized for 3 days, the water is increased by 4 to 5 per mill each time, the concentration of brine for increasing the salinity is mixed with 100 to 150 per mill prepared normal seawater until the salinity is 15 to 20 per mill higher than that of a primary pond, the brine is added into the primary pond for increasing the salinity, the brine is changed twice every day after the salinity is adjusted to 40 per mill, the salinity is increased by 2.5 per mill to 3.5 per mill each time until the salinity is 65 per mill.
6. One-to-one crude salt formation: in the 4 processes, a small pond can be built in the conditional pond according to the proportion of 100-200: 1, a plastic greenhouse is covered for heat preservation, the salinity can be matched with the same, the transportation link of the shrimp seeds can be omitted, the standard thickness can be properly increased, and the resistance of the shrimp seeds to the outside is increased.
7. Feeding fairy shrimp in the whole process: the artemia protein content is high, the crude protein content is 50-60%, the amino acid content is 21-29%, the artemia amino acid composition is similar to the shrimp body amino acid composition, the weight increase of prawns is facilitated, and the growth speed of the prawns eating the artemia is high. And (3) culturing the artemia within 65-95 per mill, and feeding the shrimps with different salinity after harvesting. The fairy shrimp is fed on the day of seedling release, the fairy shrimp is hatched in a secondary brine pond (with the salinity of 65-95 per mill) in advance, 1-1.5 kilograms per mu is fed, and the quantity is increased by 5-10% every day in two times. If the water quality transparency is more than 60cm, the feeding amount of the fairy shrimp is reduced to a half; if the water quality transparency is more than 80cm, the artemia stop feeding, the water change amount is increased, and minced fillet of the lance tail goby (C.stigmaias) fermented by lactic acid bacteria is supplemented.
8. Water quality regulation and control: the water quality can be regulated by using the wheat bran fermented by the bacillus and the lactobacillus, and the wheat bran fermented by the bacillus and the lactobacillus is used once every half month. Bacillus was used on day 1, lactic acid bacteria on day 6 and lactic acid bacteria on day 11 of each cycle.
9. And (3) water quality detection: the conventional water quality indexes DO, Ph and transparency are respectively once a day in the morning and at the evening, and the salinity, ammonia nitrogen and nitrite are respectively once a day; vibrio is administered every three days. The vibrio treating method comprises the following steps: reducing feed (oral administration lactobacillus), and increasing fairy shrimp amount; the water exchange amount is increased. The taura virus was detected every 15 days.
10. Biological prevention and control: 1.2-1.5 million seedlings are released per mu, the prawn grows for 15-20 days, the prawn grows for about 5cm, 4-5 cm of lance tail goby (C.stigmaias) with consistent salinity with the target pond is released per mu and domesticated, the ratio of the fish to the prawn is 500-1000: 1, reeds can be planted in the saline-alkali soil around the culture pond to attract some birds to lay eggs, the habitat is increased, and the birds can timely clean diseased and weak shrimps floating on the water surface, and the method is also one of effective means for disease biological control.
11. Physical prevention and control: when the shrimps grow to about 7-8 cm, by utilizing the characteristics that the sick shrimps and the weak shrimps move along the sides of the pool and attached to the water surface, a shrimp guide net is placed every 40-50 mu, the shrimp guide net is pulled to a 30-50 m 60-mesh net from the side slope to 30-50 cm underwater to 5-10 cm above the water surface, the shrimp guide net is arranged at one end far away from the side slope, the sick shrimps and the weak shrimps are induced into hubs, and the shrimps are cleaned once every 2-3 days, so that the sick shrimps and the weak shrimps are prevented from being eaten by healthy shrimps and the infection source is cut off.
12. Stress prevention: the weather mutation causes the prawns to generate stress, the stress is an important factor for the occurrence of the diseases of the prawns, and 30 g of Vc raw powder is splashed in a whole pool before and after the weather mutation (cold flow, strong wind, high temperature and the like).
Compared with the prior art, the invention has the following advantages:
1. the invention changes the primary evaporation pond of the seawater salt pan into a single culture pond, thereby enlarging the culture area.
2. The fermented minced fish of the lobster and tiger fish and wheat bran are used as the organic fertilizer water in the whole process.
3. The shrimp larvae are thickened, the standardized breeding is carried out in the early stage, and the salinization thickening is carried out in the later stage, so that the survival rate of the shrimps can be improved, and the yield per mu and the total output are greatly improved.
4. The whole process of the shrimp breeding is carried out by the fairy shrimp, which provides high-quality basic bait for the shrimp larvae, not only reduces the feed coefficient and the water pollution, but also can increase the survival rate and accelerate the growth speed of the shrimp larvae.
5. The disease prevention and control is the combination of biological prevention and control and physical prevention and control: the physical prevention and control is to arrange a shrimp guide net to eliminate the sick shrimps by utilizing the characteristics that the sick shrimps and the weak shrimps move along the sides of the pond and are attached to the water surface; the biological prevention and control is to attract birds to clean up sick shrimps and weak shrimps floating on the water surface in time by using the tail of the lance goby and the planted reed.
6. Detecting the taura virus: the germplasm, the larvae and the seedlings are selected, the detection report of the taura virus is checked, and all links are negative and can be used as the seedlings for the culture of the shrimps in the salt pan.
The invention takes good effect from comprehensive prevention and control measures such as variety selection, fry detection, pond trimming in cultivation, crude salt marking of shrimp fries, nutrition enhancement, biological prevention and control, physical prevention and control and the like.
