Abstract
The scheme discloses a method for preventing and treating fish skin ulceration in the technical field of aquatic product culture, which comprises the following steps: a. placing the sweet wormwood in a storage device, and then immersing the storage device in pond water; the storage equipment comprises a voice reminding device and a placing box, wherein a storage frame with an opening at the upper end is arranged on the upper surface of the placing box, water inlet holes are uniformly distributed in the storage frame, and a pressing cover is connected to the opening end of the storage frame in a sliding manner; the lower surface of the pressing cover is connected with a pressure sensor which is positioned right above the placing box; a controller and an air cylinder are arranged in the placing box, the air cylinder comprises a piston rod, and the output end of the piston rod penetrates through the upper end face of the placing box and is fixedly connected with the pressing cover; the controller is respectively connected with the pressure sensor, the air cylinder and the voice reminding device through electric signals; b. the volume of the sweet wormwood in each mu of fishpond is 2-4 m3And after the voice reminding device reminds by voice, the material storage equipment is taken out and the sweet wormwood is added again. The method can effectively prevent and treat fish skin ulceration.
Description
Technical Field
The invention belongs to the technical field of aquatic product culture, and particularly relates to a method for preventing and treating fish skin ulceration.
Background
The fish is a temperature-changing aquatic vertebrate which is in scales of bones, breathes by gills, swims through swinging of tails and trunk parts and coordinated action of fins and feeds by upper and lower jaws, and belongs to the subgenus of vertebrates in the phylum of chordata. In the process of fish culture, the fish often has diseases such as hemorrhage, enteritis, saprolegniasis, gill rot and the like caused by pathogenic bacteria such as columnar fiber bacteria, pseudomonas fluorescens, aeromonas and intestinal parasites. In order to reduce the occurrence of fish diseases, medicines such as bleaching powder, sodium dichloroisocyanurate, trichloroisocyanuric acid, chlorine dioxide disinfectant and the like are mainly adopted to kill pathogenic bacteria at present; the mode has good killing effect on pathogenic bacteria and intestinal parasites, but when the mode is used for killing the pathogenic bacteria and the intestinal parasites, the pathogenic bacteria and the intestinal parasites can further stimulate damaged parts of fish epidermis and fish intestinal inflammation, so that fish diseases are more serious. Meanwhile, in the process of disinfecting the fish pond, the use amount and time of the medicine are determined according to the growth condition of the fish in the fish pond by experienced breeding personnel, and the fish is easy to die due to too large addition amount or too early or too late addition time.
Aiming at the situation, in journal "ocean and fishery", 2015(9):52-52, the authors' small stone discloses a method for skillfully using chinaberry leaves to prevent and treat parasitic diseases, the method is to bundle the chinaberry leaves into small bundles and then hang the small bundles in a pond through a hanging rod, as the chinaberry leaves are soaked in water, the threads for wrapping the chinaberry leaves are easy to fall off, so that the chinaberry leaves fall into the water, and people add the chinaberry leaves mainly judge whether the chinaberry leaves are still on the hanging rod, so that the excessive chinaberry leaves are often added in the pond; the neem leaves have a killing effect on parasites and some pathogenic bacteria, but the neem leaves have toxicity, and excessive neem leaves can cause fish poisoning and death in severe cases.
Disclosure of Invention
The invention aims to provide a method for preventing and treating fish skin ulceration, and aims to solve the problems that in the prior art, when a fish pond is disinfected, the fish growth is influenced due to strong toxicity of selected medicines and uncertain medicine adding time.
The method for preventing and treating fish skin ulceration in the scheme comprises the following steps:
a. placing the sweet wormwood in a storage device, and then immersing the storage device in pond water; the storage equipment comprises a voice reminding device and a placing box, wherein a storage frame with an opening at the upper end is arranged on the upper surface of the placing box, water inlet holes are uniformly distributed in the storage frame, and a pressing cover is connected to the opening end of the storage frame in a sliding manner; the lower surface of the pressing cover is detachably connected with a pressure sensor, and the pressure sensor is positioned right above the placing box; a controller and an air cylinder are arranged in the arrangement box, the air cylinder comprises a piston rod, and the output end of the piston rod penetrates through the upper end face of the arrangement box and is fixedly connected with the press cover; the pressure sensor unidirectionally sends data to the controller, and the controller respectively unidirectionally sends the data to the air cylinder and the voice reminding device;
b. the volume of the sweet wormwood in each mu of fishpond is 2-4 m3And after the voice reminding device reminds by voice, the material storage equipment is taken out and the sweet wormwood is added again.
The working principle of the scheme is as follows: set for the cylinder through the controller and carry out the biggest of function, middle and minimum pressure value, through controller control cylinder, make the piston rod of cylinder stretch out, and then drive the pressfitting lid rise rather than being connected, after the pressfitting lid surpassed the storage frame, place the storage frame with the sweet wormwood through the space between pressfitting lid and the storage frame in, the sweet wormwood is placed and is accomplished the back, and the piston rod of cylinder is retracted, and then drives the pressfitting lid and slides down and compress sweet wormwood and reach the intermediate pressure value until pressure sensors. After the storage equipment is placed in a fish pond, water enters the storage frame through a water inlet hole in the storage frame and contacts with the sweet wormwood, along with the soaking and dissolution of the sweet wormwood in the water and the gnawing of fish, along with the sinking of the sweet wormwood, the pressure value sensed by the pressure sensor is reduced and the value is fed back to the controller, the controller starts the air cylinder again to enable the piston rod of the air cylinder to retract, and then the pressing cover is driven to extrude the sweet wormwood until the pressure sensor reaches the intermediate pressure value; along with the continuous dissolution or decomposition of the sweet wormwood herb in the pond, the piston rod drives the pressing cover to compress the sweet wormwood herb for multiple times, the pressure sensor on the pressing cover is in contact with the upper surface of the placing box, and when the pressure value sensed by the pressure sensor after the contact reaches the maximum pressure value set by the controller, the controller controls the air cylinder to stop operating and controls the voice reminding device to carry out voice reminding; the fish breeder can take out the storage equipment and put the sweet wormwood herb into the storage frame and put the sweet wormwood herb into the fish pond.
The beneficial effect of this scheme: 1. sweet wormwood is selected as a medicine for preventing and treating fish skin ulceration, and has the effects of clearing deficiency heat, removing bone-steaming, relieving summer-heat, preventing malaria, removing jaundice, stopping bleeding, cooling blood, disinfecting and the like. Meanwhile, the sweet wormwood has strong volatile fragrance, can attract fishes to gnaw, and has an anti-inflammatory effect on effectively treating intestinal inflammation of the fishes after the fishes gnaw the sweet wormwood. In addition, after the sweet wormwood is placed in the fish pond, part of nutrient substances are dissolved in water under the soaking of the sweet wormwood in the water, so that the water in the fish pond is similar to liquid medicine, and the sweet wormwood is beneficial to killing part of germs; the fish swims in water and contacts with the drug soaked in the sweet wormwood herb, so that the skin damaged by the fish is repaired, and the bleeding of the fish is reduced, thereby further having the effects of treating the fish hemorrhagic disease, enteritis, gill rot, red skin disease, branchiomycosis, bubble disease and sinergasia.
In addition, after the sweet wormwood is decomposed in water, nutrient substances in the fish pond are increased, favorable conditions are provided for the growth of microorganisms such as bacillus cereus and bacillus subtilis, and a large amount of feed is provided for fish due to the large growth of the microorganisms, so that the fish growth is facilitated. Meanwhile, the bacillus cereus can generate antibacterial substances, inhibit the propagation of harmful microorganisms, degrade nutrient components in soil and improve the environment of the fish pond. Active substances such as subtilin, polymyxin, nystatin, gramicidin and the like generated in the growth process of bacillus subtilis have obvious inhibiting effect on pathogenic bacteria or conditionally pathogenic bacteria of endogenous infection, and further the occurrence of fish diseases is reduced. The bacillus subtilis can also stimulate the growth and development of fish immune organs, activate T, B lymphocytes, improve the levels of immunoglobulin and antibody, enhance the cellular immunity and humoral immunity functions, improve the fish immunity and further prevent diseases. The bacillus subtilis can also synthesize a plurality of B vitamins such as vitamin B1, B2, B6, nicotinic acid and the like, improves the activity of interferon and macrophage in fish bodies, and has positive effect on preventing and treating fish skin ulceration.
2. When the sweet wormwood is thrown, storage equipment is adopted, the storage equipment is provided with a controller, and the controller extrudes the sweet wormwood by receiving a pressure value transmitted by a pressure sensor and then passing through an air cylinder; after the sweet wormwood is decomposed, the pressure sensor is in contact with the placement box, so that the pressure value of the pressure sensor is increased, and when the pressure value reaches the maximum value set by the controller, the controller controls the voice reminding device to send voice reminding. Because at the decomposition in-process of sweet wormwood, sweet wormwood is all the time in the storage frame, only when its decomposition completion back, pronunciation reminding device just can take place to remind, and then has avoided adopting the peg control medicine among the prior art, and the medicine is in the pond of landing easily, and then has accelerated the interpolation cycle of medicine, leads to the medicine use amount too big, influences the problem that fish grew.
The sweet wormwood adopted by the scheme has low toxicity, is safe to use and generally has no obvious adverse reaction; meanwhile, the material storage equipment is used for putting in the sweet wormwood herb, so that the problem of excessive putting in the sweet wormwood herb is solved.
Furthermore, the pepper is thrown into the fish pond 3-5 times per month, and the throwing amount of the pepper in each time of each mu of the fish pond is 0.6-0.8 kg. During the decomposition process of the sweet wormwood, after the sweet wormwood is dissolved in water, a large amount of microorganisms such as bacillus cereus and bacillus subtilis can be rapidly expanded, although the bacillus cereus and the bacillus subtilis both have an inhibiting effect on the growth of pathogenic bacteria, excessive bacillus cereus can generate a large amount of enterotoxin and is not beneficial to the growth of fish; excessive bacillus subtilis quickly consumes free oxygen in intestinal tracts to cause hypoxia of the intestinal tracts, so that fish are easy to lack oxygen. The capsaicin in the capsicum has obvious inhibition effect on bacillus cereus and bacillus subtilis, so that the excessive growth of the bacillus cereus and the bacillus subtilis is prevented, and the capsaicine plays a key role in the healthy growth of fishes. Meanwhile, the capsicum contains a large amount of capsaicin, which has the functions of promoting appetite and improving digestion, and simultaneously, the capsicum has better inhibiting or killing effects on various pathogenic bacteria such as columnar fiber-philic bacteria, rhizoctonia solani and the like, so that the occurrence of fish hemorrhagic disease, gill rot disease, saprolegniasis and the like can be further inhibited.
