Range of shrimp species

(1) Red body disease of shrimps

Shrimp erythroid disease is caused by infection of various vibrios. The main symptoms are: the tail of the shrimp becomes red at the initial stage of the attack, then the tail of the shrimp expands to the swimming feet and the whole abdomen, and finally the whole feet become red. The sick shrimps have dull movements, decline in appetite or stop eating, and can cause large-area death in severe cases. The disease is mainly caused by infecting vibrios after shrimp bodies are injured, and most of the disease is caused 1 to 3 days after stocking, removing enemy and selecting and catching. Generally in the hot season of 7-8 months.

1. Prevention: the first method is to clean the excess sludge in the pond and use quicklime to clean the pond thoroughly before stocking. And the second method strengthens the management of the ecological environment, improves the water level and stabilizes the water quality.

And thirdly, sprinkling strong iodine 130 g/mu.m in the whole pool.

(2) Black spot of shrimp

The main causes of the shrimp melasma are the deterioration of water quality and substrate and the mass propagation of some bacteria which can decompose chitin and detritus. The symptoms of the disease are shown in black ulcer spots on the shells of the diseased shrimps, usually on the gills and the abdomens, including the walking feet and the swimming feet, and the diseased shrimps have greatly reduced vitality when being serious or lie on the sides of the pond and are in an endangered state.

And (3) prevention and control: firstly, water is periodically injected and changed, and the water quality is kept fresh. ② periodically splashing quicklime water or water quality modifier (such as Hanbao hyperconcentration photosynthetic bacteria).

Fourthly, using 130 g/mu.m of strong iodine or 150 g/mu.m of strong chlorine for 2 to 3 times continuously during the epidemic period of the disease.

(3) Shrimp black gill disease:

the diseases of the shrimp black gill are mainly caused by the following reasons: firstly, the branchia part of the shrimp is infected by mould and bacteria, so that the branchia part of the shrimp body is damaged; secondly, the heavy metals such as copper element content at the bottom of the pond is too high, the shrimps can be poisoned by copper, and the gills are black and precipitated to influence respiration; the chemical reaction in the shrimp body can not be carried out due to the long-term lack of vitamin C, so that the shrimp body is thin and weak and dies; and fourthly, excessive suspended organic matters in the pond water are accumulated in the branchia to influence the breathing of the shrimps. The main symptoms are: the diseased shrimps have black gill filaments and are locally rotten, and part of the diseased shrimps are accompanied by black spots on the side surfaces of the cephalothorax and the abdominal shell. The sick young shrimp has weakened vitality, slowly swims on the bottom layer, has weakened phototaxis, prolonged metamorphosis period or no metamorphosis, curly abdomen, white body color and no ingestion. When adult shrimps are ill, they usually float on the water surface and move slowly.

And secondly, splashing 15-20 mg/L of quicklime into the whole pool periodically to treat the black gill disease caused by excessive organic matters in suspended matters in water. In the third method, a large amount of water is changed for the gill disease caused by heavy metals, 1-2 per mill detoxification-safety Hanbao is used for sprinkling, and meanwhile, a proper amount of high-stability easy-to-restore Vc (1 per mill) is added into the feed.

(4) Black shell disease of shrimps

The shrimp black shell disease is also called black shell disease and moss disease. The etiology is caused by some attached algae, mainly attached diatoms, brown algae, filamentous algae, and the like. The main symptoms are: the shrimp body surface is attached by algae, the body color becomes black or dark green, the severely infected person is wrapped by the moss, the sick shrimp has poor constitution, the activity is obviously weakened, the shrimp cannot smoothly exuviate, and the shrimp can be killed in large scale when meeting the oxygen deficiency in the pond.

And (3) prevention and control: cleaning and disinfecting the pond strictly, changing water frequently and keeping the water quality fresh. And photosynthetic bacteria are used regularly to improve the culture environment. ③ in the epidemic season, the Chinese prickly ash can be used for removing 150 g and 200 g/mu.m, and the dehulline auxin (5 per mill) is taken internally.

The main symptoms are: the surfaces of the body surfaces, gills, appendages and the like of the sick shrimps are attached with light yellow cotton floccules which parasitize on the gills, so that gill tissues are degenerated or necrotized to cause bacterial secondary infection. When the number of the shrimps is large, the shrimp load is increased, respiration and activity are influenced, and the shrimps die by suffocation in severe cases.

And (3) prevention and control: the first method is to clean the excess sludge in the pond and solarize the whole pond. In the second method, strong iodine 130 g/mu.m is sprinkled in the whole pool. And thirdly, sprinkling the zinc sulfate by using 1-3 mg/L of the zinc sulfate or sprinkling the potassium manganate by using 1 mg/L of the potassium sulfate in the whole pool.

(6) Muscular necrosis of shrimps

The shrimp muscle necrosis is also called as white turbidity disease and white body disease. The cause of the disease is not clear, and the disease can be induced when the water temperature is changed greatly or the water temperature is too high, oxygen is deficient and the water quality is deteriorated after the young shrimps and the adult shrimps are transported for a long distance. The main symptoms are: the tail or back muscles of the freshwater shrimps initially present a round or irregular white area, and then the whitish area rapidly expands to the whole back until the freshwater shrimps are turbid and become flaky, the bodies of the sick shrimps are bent, the activity is slow, the food intake is reduced or the sick shrimps do not eat food, and finally the dead shrimps are caused. The disease can be caused to both larvae, young shrimps and adult shrimps, wherein the harm to parent shrimps and larvae is the most serious.

And (3) prevention and control: the first method is to thoroughly disinfect the pond and kill bacteria. And secondly, periodically applying lime water. And thirdly, sterilizing the shrimp larvae with 200 g/mu.m of dibromohydantoin for the Hanbao aquatic products once before the shrimp larvae enter the pond. And in the fourth method, the operation of the shrimps is careful during transportation, the water leaving time is not suitable to be too long, and the temperature difference of water temperature cannot be too large when the shrimps are put into the pond. The pond water is kept fresh and cool at ordinary times, the dissolved oxygen is sufficient, and new water is injected frequently. The fifth method is that the Hanbao is used regularly to mix with Vc (1 per mill) which is easy to reduce and feed.

(7) Health advice for shrimp and crab

Various diseases can be caused due to unbalanced nutrition and deterioration of water quality in a long-term process of shrimp and crab cultivation, and various vitamin deficiency diseases are more easily caused particularly in a growth period and a shelling period. In order to improve the immunity and disease resistance of the shrimps and crabs, necessary health care measures are taken in each period.

And (3) shelling: adding 1.0% of chitin and 0.1% of Hanbao multivitamin into the feed, and adding oxygen all day long.

The symptom of crab shelling is caused by imbalance of calcium and phosphorus proportion in water or deficiency of certain minerals or deterioration of water quality and anoxia. The main symptoms are: when the crabs are not completely hulled or have more hulls, the crabs are swelled and die, and the disease mainly occurs in the hulling peak period of 7-9 months.

And (3) prevention and control: in the first method, after the pond is cleaned, a plurality of waterweeds (waterweeds, anabaena and the like) are planted on the beach surface at the bottom of the pond. And secondly, regulating and controlling water quality, keeping the water quality fresh, and regularly splashing monocalcium phosphate, quicklime and the like in the whole pool. And thirdly, properly controlling the stocking density (below 800 tails/mu), and keeping the water level stable without flushing and draining water during the hulling peak. And in the fourth method, the pond with the aerator needs to be started in bad weather. And fifthly, adding dehulled auxin (5 per mill) into the plant feed regularly.

(4) Ciliate disease of crab

Crab ciliates are caused by sessile ciliates, and the main species are: polycondensation insects, tired branch insects, short borers, closteron insects, single condensation insects, sucking insects and the like. The main symptoms are: the body surface and appendage of the diseased crab are attached with the faint yellow cotton floccule parasitism. The parasitic quantity of the gill part of the larvae can influence respiration, severe people suffocate and die, the parasitic quantity of the body surface and the appendages can make the crabs move hard, and severe people do not exuviate and influence growth. Such symptoms occur both in the young and during the period of development.

1. Prevention: in the first method, lime water is applied for disinfection. And the second method is to regularly use 150 g/mu.m dibromo hydantoin and 60-70 g/mu.m sea sound for Hanbao aquatic products.

2. Treatment: the first method is that the young crab is splashed with strong iodine 130 and 200 g/mu.m in the whole pool. In the second method, the amount of the compound A used in the growing period is 200-300 g/mu.m. The method III uses 500 grams of zinc sulfate monohydrate per mu m, and adds 100 grams per mu m of the dibromohydantoin for aquatic products, the effect is obvious, and the dibromohydantoin is used once every 15 to 20 days.

(5) Gill rot disease of crabs

The gill rot disease of crabs is caused by infection of vibrio or aeromonas hydrophila. The main symptoms are: the gill silk becomes yellow, gradually becomes necrotic and decays, and is atrophied and shed when the gill silk becomes severe. Such diseases often occur during the period of development, particularly when poor feed composition or eutrophication of water quality is encountered.

1. Prevention: the first method is to thoroughly remove excessive sludge at the bottom of the pond and solarize the bottom of the pond. In the second method, the feed fish must be disinfected, and the feed fish is soaked in 100 ml of strong iodine per 1000 kg of fish for disinfection and then fed.

The second method is to sprinkle 130 g/mu.m of bactericidal red or 270 g/mu.m of dibromohydantoin 200-.

(6) Black gill disease of crab

The black gill disease of crabs is caused by various reasons: the gill part is infected by mould and bacteria. ② the heavy metal content at the bottom of the pond exceeds the standard, which causes the water quality deterioration, the crab poisoning, the melanin precipitation at the gill part and the influence on the respiration. And the long-term lack of vitamins can lead the biochemical reaction in the crab body to be unable to be carried out, thus leading the crab to be thin and weak. Excessive organic matters (suspended matters) in the pool water are accumulated in the gills to influence the breathing of the crabs. The main symptoms are: the diseased crab gill threads are black or dark gray and locally rotten. Part of diseased crabs are accompanied by side black spots of the breastplate and the abdominal shell, the activity is reduced, the prescription of the commonly used fishery disease is withdrawn, and the molting period is prolonged or can not be molted. The disease is mostly caused in the later stage of breeding and large-sized crabs.

1. Prevention: the first method is to sprinkle 10-15 kg/mu.m of quicklime in a full pool 2 times a month. And in the second method, photosynthetic bacteria are sprayed periodically to improve the water quality.

2. Treatment: in the first method, the bacterial gill disease is splashed by sterilizing red 130 g/mu.m in a full pool for 2 times, and high-stability easy-to-restore Vc (1 per thousand) and florfenicol powder (1 per thousand) are added into plant baits. In the second method, the Holotrichia parallela caused by excessive suspended organic matters in water is periodically disinfected by Hanbao strong chlorine. And thirdly, changing a large amount of water caused by heavy metals, sprinkling 600 g/mu.m of the Hanbao detoxification medicine in a whole pool, and periodically adding high-stability easy-to-reduce Vc (1 per thousand).

(7) Edema disease of crab

The crab edema disease is mainly shown in the unhardened part of the crab after shelling, and the watermark is obviously shown. The mortality rate is relatively high, but is often unnoticed on site because such crabs are cannibalized after most of them die or are about to die.

1. Prevention: the method I comprises the steps of periodically sprinkling photosynthetic bacteria of Hanbao in a whole pool to adjust the water quality environment; during the cultivation process, especially during molting, the disturbance is reduced as much as possible to avoid injury. And in the second method, the substrate is improved by using the Hanbao substrate modifying agent regularly for the old culture pond.

2. Treatment: the first method is that the whole pool of dibromine hydantoin 200-. The second method, the strong iodine is sprinkled in the whole pool with 200 g/mu.m of the strong iodine when the symptom is found, and the strong iodine can be continuously used for 2 times. And thirdly, periodically adding 1 per mill of Hanbao florfenicol powder and 1 per mill of Hanbao high-stability easy-to-reduce Vc.

(8) Tremor disease of crabs

The cause of crab shaking disease is mainly small RNA virus and is caused by synergistic environmental deterioration. The main symptoms are: necrosis of liver and pancreas, unstable standing, difficulty in turning over, stopping eating, roaming around the pond, and finally failing to die.

1. Prevention: the first method is to thoroughly remove excessive sludge at the bottom of the pond and solarize the pond. And in the second method, water is periodically added and replaced to keep the water quality fresh.

2. Treatment: in the first method, the Hanbao florfenicol powder (1 per mill), high-stability easy-to-reduce Vc (1 per mill) and crab shivering are periodically added into the plant feed. In the second method, the first step is to kill external parasites, the whole pond is splashed with dibromine hydantoin 200 g/mu.m or strong iodine 200 g/mu.m for Hanbao aquatic products, and the bactericidal aldehyde 130 g/mu.m.

Range of frogs

(1) Red leg disease

The etiology is as follows: the red leg disease is also called septicemia, and is a common disease of tadpoles, frogs and adult frogs. The pathogens are gram-negative bacteria such as aeromonas hydrophila, acetic acid-free strains of acetobacter and acinetobacter calcoaceticus, and the like. The disease can occur all the year round, the infection is fast, and the death rate is high.

Symptoms are: the affected individuals have lassitude, impaired mobility, abdominal distension, and bloody mucus in the mouth and anus. In the early stage of the disease, the toe tip of the hind limb is red and swollen, has a bleeding point and quickly spreads to the whole hind limb. After the autopsy, a large amount of ascites in the abdominal cavity, enlargement of the liver, spleen and kidney with bleeding spots, congestion of the stomach and intestine and filling of mucus can be seen.

And (4) control measures: the water is changed regularly, the water quality is kept fresh, the culture density is reasonably controlled, food is fed regularly and quantitatively, the diseased individuals are separated and treated in time, and the disease spreading is controlled.

The treatment scheme comprises the following steps: at the early stage of onset, the following protocol can be adopted: 100g of 10% enrofloxacin (the products in the market are more counterfeit products, and need to be selected from a regular factory) +160g of peptidase Jiean, and mixed with 20kg of feed for one treatment course, wherein one treatment course is 5 days. Meanwhile, the whole grand ceremony pond is used for disinfection, 500ml grand ceremony is used, and 2000 cubic meters of water is used.

(2) Air blister disease

The etiology is as follows: the water contains many phytoplankton, and under the condition of strong illumination, the photosynthesis of the plants generates a large amount of oxygen, so that the dissolved oxygen in the water is excessively saturated; when the soil pond is used, underground water is excessively saturated with nitrogen or underground methane; the temperature suddenly rises, which causes the dissolved gas in the water to be excessively saturated; the over-saturated gas forms bubbles, the tadpoles continuously swallow the bubbles in the process of taking food, and the bubbles are excessively gathered in the tadpole digestive tube to cause the bubble disease.

Symptoms are: the tadpole intestinal tracts are full of gas, the abdomen expands, the body loses balance and floats on the water surface, and when the tadpole intestinal tracts are serious, the expanded bubbles obstruct normal blood circulation and damage the heart. Congestion of the intestinal wall was visible after dissection.

And (4) control measures: changing water frequently, keeping the water quality fresh, and controlling the number of aquatic organisms in the pool. When the bubble disease is found, the sick individuals can be fished out by using a fishing net and put into clear water, and the patients do not feed food for 2 days, so that part of individuals can be cured by themselves. In addition, salt can be added into the culture pond to relieve the disease condition, and about 15 g of salt is added into each cubic meter of water body.

(3) Meningitis

Symptoms are: the patients have poor spirit, slow movement, anorexia, and obvious blood spots on hind limbs, abdomen and around mouth of the diseased tadpoles. The abdomen of part of tadpoles is enlarged, and the tadpoles float upward on the water surface and do not rotate freely, and sometimes return to normal. When the abdominal cavity is dissected, a large amount of water is accumulated in the abdominal cavity, the liver is blackened and swollen, bleeding spots exist, the spleen is shrunk, and the intestinal tract is congested. Meanwhile, "head distortion" and eyeball "cataract" are typical symptoms thereof.

The treatment scheme comprises the following steps: at the early stage of onset, the following protocol can be adopted: 100g of Fukang (10% florfenicol, which is a product in the market with more counterfeit goods, a regular large factory) +160g of peptidase-kinase-A is selected and mixed with 20kg of feed, and the frog is preferably completely cultured for one treatment course, wherein the treatment course is 5 days. (particularly, if the dosage and the treatment course are not achieved, the disease is frequently relapsed, thereby increasing the treatment difficulty of the disease); for the pond of the disease culture, the number of the pond can be increased to 7 days. Meanwhile, the whole grand ceremony pond is used for disinfection, 500ml grand ceremony is used, and 2000 cubic meters of water is used.

The following scheme can be adopted in the peak period of the disease onset: 100g of Shengfukang (10% of florfenicol, the products are more counterfeit goods in the market, a regular large factory) +200g of per gram (sulfadiazine + methoxybenzidine) +160g of peptidase una are selected and mixed with 10kg of feed, and one treatment course lasts for 5 days. (particularly, if the dosage and the treatment course are not achieved, the disease is frequently relapsed, thereby increasing the treatment difficulty of the disease). Chlorine dioxide and disinfectant pill are added to strongly disinfect.

If the cataract phenomenon is serious, the anthelmintic needs to be fed for one course of treatment: fishing is finished; 200g of the fish are mixed with 20kg of feed and orally taken for 3 days.

(4) Saprolegniasis of saprolegniasis

The etiology is as follows: tadpoles and adult frogs in the wintering period are susceptible to the disease, and the pathogen is water mold and is caused by trauma.

Symptoms are: the inner hypha of the water mold grows in the skin of the body surface of the animal, the outer hypha forms cotton-like villi on the body surface, and the hypha absorbs nutrient substances of the tadpoles and the frog bodies, so that the tadpoles and the frog bodies are thinned and have dysphoria. The proteolytic enzyme secreted by the hyphae also festers the skin and muscles where the hyphae grow.

And (4) control measures: the transportation and pool separation process is carefully operated, so that the trauma is cautiously prevented. And (4) in low-temperature seasons (the water temperature is lower than 20 ℃, the seed frogs and tadpoles are prevented from being captured and transported as much as possible). Once the disease occurs, 500ml of shenquan can be used per cubic meter of water, 1200 cubic meters of water can be used for full-pool splashing, and the saprolegniasis can be inhibited and treated to a certain extent.

(5) Enteritis (enteritis)

The etiology is as follows: the enteritis is easily caused by feeding unclean baits, and pathogens are bacteria, possibly aeromonas and streptococcus. If natural fly maggots are put in the container, enteritis is easily caused if the sterilization treatment is not proper, and the fly maggots die in large quantities.

Symptoms are: the sick frogs hang down on the head and back, so the body is emaciated, the activity is abnormal, the food intake is obviously reduced, the reaction is slow, and the tadpoles mostly float on the water surface after the onset of the disease.

And (4) control measures: the occurrence of enteritis is mostly related to unclean water and food, so water needs to be changed regularly to keep the water quality fresh; without feeding moldy and deteriorated bait, and adding garlic and Sanhuang powder. In addition, gastroenteritis is also caused by overeating, so that the bait feeding needs to be timed, quantified and fixed in point. Timely sterilizing water, using a full pool of a grand ceremony, 500ml of a grand ceremony, and using 2000 cubic meters of water. And 100g of 10% enrofloxacin, 50g of changning (5% neomycin sulfate), 160g of peptidase-kinase-A and 20kg of feed are mixed in the bait for 3 days continuously.

(6) Dystocia

The etiology is as follows: the temperature is high in winter hibernation, the temperature difference changes greatly and frequently, and if the water temperature is not controlled well in the hibernation period and the frogs repeatedly revive from the hibernation state, the frogs are very easy to produce difficultly and even do not lay eggs. The main reasons are as follows:

excessive interference and excessive physical consumption during the dormancy; ② the female frogs are over-aged and weak; the male frogs are insufficient in quantity, and the male frogs and the female frogs are not coordinated in proportion; fourthly, the environment of the spawning pond is not suitable for spawning, such as too deep water level and not quiet enough; fifthly, the breeding frogs are severely frightened before spawning; sixthly, the spawning time is inaccurate.

Symptoms are: the female frog is expanded in the abdomen and has already finished dropping eggs, but the eggs are retained in the uterus and cannot be produced. After dissection it was visible that the dark egg mass had dissolved in the uterus.

And (4) control measures: a quiet environment is created for the female frogs which lay eggs, and the breeding frogs are matched according to reasonable male and female proportion (the male and female ratio is preferably 1: 1). Before hibernation, the rana nigromaculata is fed with peptidase for a treatment course (7 days) to strengthen the physique of the rana nigromaculata, and is beneficial to spawning and breeding of the rana nigromaculata nigra in the next year.

(7) Rotten skin disease and mouth rot disease

The etiology is as follows: the skin disease is a common skin disease of frogs and adult frogs, and skin inflammation and ulceration are caused by skin trauma and bacterial infection (gram-positive bacteria such as staphylococcus). The disease can be caused by too high cultivation density and insufficient bait.

Symptoms are: in the early stage of the disease, the skin of the diseased frog is partially congested and inflamed, sometimes, the front part of the tip of the mouth is ulcerated, the skin of the body is intact, and the nasal bone is completely exposed when the disease is serious. The sick frog has bradykinesia, lassitude, stop taking food, and ulcerate at many parts of body surface.

And (4) control measures: after the disease occurs, the water body is disinfected in time, and the water body can be disinfected in a full grand ceremony pond with 500ml of grand ceremony and 2000 cubic meters of water body. And 100g of 10% enrofloxacin, 50g of changning (5% neomycin sulfate), 160g of peptidase-kinase-A and 20kg of feed are mixed in the bait for 3 days continuously. The following scheme can be adopted for oral administration: 100g Shengfukang +160g peptidase-stimulated-an, and is mixed with 20kg of feed, and the frog is preferably completely cultured for one treatment course, and one treatment course is 5 days.

(8) Leech (leech) infection

Some Rana chensinensis farms suffer from leech damage, and in severe cases, a frog bites more than ten leeches. Leeches secrete toxins with anesthesia and anticoagulation effects when being bitten and sucked, and since the blood plasma of the rana nigromaculata itself is very little and only 1-2 drops, the leeches are adsorbed on the affected part for a long time until the rana nigromaculata dies due to insufficient sucking, and even the whole rana nigromaculata of the whole farm is used for covering.

And (4) control measures: the pond cleaning work is the fundamental measure for preventing and treating the disease before the frogs are placed in the frog pond.

(9) Lernaea disease

The etiology is as follows: due to mistaking of the wrong head .

The disease symptoms are as follows: if 3-4 lernaea are parasitized on the tadpole body, the tadpole can quickly cause first death. If 1-3 parasites are parasitized, the tadpoles can be stopped from growing and gradually lean to die, although the tadpoles cannot die immediately.

The control method comprises the following steps: soaking tadpoles in potassium permanganate dropping liquid with the concentration of 10-15 mg/L for 10-20 min, continuously using for 2-3 times every day, and scattering crystal trichlorfon (the content is more than 90%) with the concentration of 0.3-0.5 mg/L in a whole pool. It is used once more every few days.

(10) Red spot disease (also known as disease)

The etiology is as follows: bacterial, fungal infections.

For improving the oxygen injection concentration in water, on one hand, the oxygen is increased by using organisms, so that sufficient plant nutrient elements and illumination in water are ensured to increase the quantity of phytoplankton population. On the other handThe artificial oxygenation comprises mechanical oxygenation and chemical oxygenation. The mechanical oxygenation mainly adopts water with high dissolved oxygen injected by a person, belongs to water supplementing oxygenation, or uses an aerator to stir water, so as to increase the dissolving speed of oxygen in the air to the water. Chemical oxygenation is the release of oxygen, such as calcium peroxide (Ca0), into water by means of a chemical agent. CaO2 is white crystalline powder, and can release oxygen by chemical reaction with water₂+H₂O=Ca(OH)₂+O_2,The calcium peroxide is applied once a month, 50-100kg is applied to each hectare for the first time, and half can be reduced later. When the organic matter load of the water substrate is too high, the dosage can be in a high limit, otherwise, the dosage is in a low limit. The calcium peroxide can not only increase oxygen, but also increase the shout degree and hardness of the water body, improve the pH value, flocculate organic matters and colloidal particles and play a role in improving the water quality and the substrate.
