Embodiment 1

[0019] Neem bark 6000g, flavescens 3700g, ginger 1300g, pepper 400g, mung bean 600g, Codonopsis 800g, wild chrysanthemum 1800g.

[0020] Preparation:

[0021] 1) Crush each raw material into coarse powder, extract by percolation method, use 70% ethanol as solvent, soak for 24 hours, slowly percolate at a rate of 10ml per minute per kilogram, and collect 10 times the weight of the medicinal material liquid, recover the ethanol until it has no alcohol smell, and obtain the alcohol extract and medicinal residues for subsequent use;

[0022] 2) Add 10 times the amount of water to the dregs, decoct for 2 hours, and separate the liquid medicine;

[0023] 3) Add 10 times the amount of water to the medicinal residue obtained in step 2), decoct for 2 hours, and separate the medicinal liquid;

[0024] 4) Filter the second decoction solution of step 2) and step 3) with a 100-mesh sieve, and when the filtrate is concentrated to a relative density of 1.02, use a tubular high-speed centr...

Embodiment 2

[0029] Neem bark 6500g, flavescens 3500g, ginger 1500g, pepper 300g, mung bean 700g, Codonopsis 700g, wild chrysanthemum 2000g.

[0030] The preparation method is the same as in Example 1.

[0031] Stir the fish medicine into the feed by 0.2% of the fish body weight and mix evenly.

Embodiment 3

[0033] Neem bark 7000g, flavescens 3300g, ginger 1700g, pepper 200g, mung bean 800g, Codonopsis 600g, wild chrysanthemum 2200g.

[0034] The preparation method is the same as in Example 1.

[0035] Stir the fish medicine into the feed by 0.2% of the fish body weight and mix evenly.

[0036] From July 1st to July 10th, 2014, a 10-day experiment on the effect of fish medicine was carried out in a fish farm in Zhoushan City, Zhejiang Province. 400 fish infected with small meloniosis were divided into 4 groups on average, of which 1 group The control group was fed with common fish medicines, and the other three groups were fed with the fish medicines of Examples 1-3 every day. The results are shown in Table 1:

Abstract

The invention provides a fish medicine for treating ichthyophthiriasis. The fish medicine is characterized by being prepared from the following raw materials in parts by weight: 50-80 parts of cortex meliae, 30-40 parts of radix sophorae flavescentis, 10-20 parts of ginger, 1-5 parts of pepper, 5-10 parts of mung bean, 5-10 parts of codonopsis pilosula and 15-25 parts of chrysanthemum indicum. The fish medicine has the advantages of good prevention effect, little side effect and no pollution to fish ponds.

Description

technical field [0001] The invention belongs to fish medicine, in particular to a fish medicine for treating small melon worm disease. Background technique [0002] Small melon worm disease is a common fish disease. The body surface and gill flaps of the diseased fish are covered with white dot-like worms and cysts, which are visible to the naked eye, so it is also called white spot disease. The mucus on the head, trunk and fin rays of the body surface increases significantly, and it is mixed with the insect body, which seems to have a thin film. The melon worm disease has an obvious onset season, and spring, autumn and early winter in the south are popular seasons. After the mature melon worm leaves the fish body, the body secretes transparent and elastic cysts, sinks to the bottom of the water or attaches to aquatic plants and plant debris, and then begins to divide. After 9 to 10 divisions, 300 to 1000 larvae are formed. At 15 to 20 degrees Celsius, after about 24 hours...
