The eel and loach slaughtering machine is formed by a rack, a feeding barrel and a slaughtering device, wherein the feeding barrel is mounted at the one end of the rack and the slaughtering device is arranged at the other end of the rack; the feeding barrel and the slaughtering device are movably connected through a feeding hose and a hose clamp; and the slaughtering device is provided with a protection cover. The eel and loach slaughtering machine disclosed by the invention adopts a feeding roller to randomly grasp and convey eel and loach, the slaughtering speed is high, the slaughtering requirements on eel and loach with different sizes can be met, and the frequent problems that some eel and loach are not correctly slaughtered or are not slaughtered when an existing slaughtering machine is used for slaughtering eel and loach with different sizes are solved. When the eel and loach slaughtering machine disclosed by the invention is used for slaughtering eel and loach, eel and loach do not need to be classified according to specifications and sizes in advance, so that the labor intensity of workers is reduced and the working efficiency is improved; and eel and loach can be slaughtered from abdomens or from backs through the selection connection between the feeding hose and a back cutting supporting plate and between the feeding hose and an abdomen cutting supporting plate, and furthermore, the requirements on deep processing of eel and loach can be met.

The invention discloses a pond for artificially culturing misgurnus anguillicaudatus, and relates to the field of aquaculture. The slope-protected pond is 2,000-3,000 square meters in area and is rectangular, the length-width ratio is 2:1 or 3:2, the pond depth is 80-150 centimeters, and the thickness of sludge at the bottom of the pond does not surpass 30 centimeters; the bottom of the pond inclines towards a water outlet, a fish pit connected with the water outlet is arranged, is 5 percent the area of the bottom of the pond and is 30 centimeters lower than the bottom of the pond; a water inlet is formed 20 centimeters below the bank surface of a pond bank, and the bank surface of the pond bank is 150 centimeters in width; the water inlet is made of a PVC (Polyvinyl Chloride) pipe, and is 30-40 centimeters in diameter; a filter screen which is made of dense screen cloth and is used for intercepting pests is arranged on a pipe orifice; the water outlet is formed in the bottom of the fish pit at the bottom of the fish pond obliquely opposite to the water inlet; a gate valve is arranged at the water outlet close to the pond bank; an escape-proof net is arranged. In the pond for artificially culturing misgurnus anguillicaudatus provided by the invention, a medicinal soil layer is paved, and a blended Chinese medicinal composition can be used for inhibiting and killing major pathogenic bacteria of misgurnus anguillicaudatus and has good prevention and control effects on bacterial diseases of misgurnus anguillicaudatus; the medicinal soil layer and clay are blended, the pesticide effect can be released out slowly after contact with water, and the clay has the effect of controlling the release of the pesticide effect.

The invention discloses a method for cultivating loach larvae by arranging net cages in a pond to improve the rate of survival. The method mainly comprises the steps that firstly, the pond which is appropriate in area and water depth is selected, water is injected into the pond to clean and disinfect the pond, and palatable bait is prepared; secondly, the net cages with the total area being 10% of the area of the pond are arranged inside the pond, wherein each net cage conforms to the standard of (5-8)m*1m*0.7m, the net mesh is 60, the net cages are evenly arranged along the long edges of the pond in a multi-line and two-row mode, and the cage bottoms are close to the bottom of the pond but not make contact with the bottom mud when the net cages are fixed; thirdly, four submerged pumps are installed at the four corners of the pond, and pond circulating small-flow water is formed by adjusting the direction of a water outlet; fourthly, loach larvae are thrown into the net cages according to the demand of 2250-3000 loach larvae per square meter, the submerged pumps are started, and wheel animalcule and other palatable bait enter the net cages along water flow to be eaten by the loach larvae; fifthly, unobstructed exchanging of water inside and outside the net cages is guaranteed, and the bait is thrown into the net cages in due time to ensure adequate bait; sixthly, the loach larvae are moved out of the net cages when growing to be 2 centimeters long, the net is dragged out, aquatic insects in water are removed, then the loach larvae are moved to the pond to be bred, the bait is thrown into the pond in due time, and the loach larvae are bred to be larvae being 4 centimeters to 5 centimeters long.

The invention relates to a tilapia and loach mixed-pool-breeding method. A tilapia breeding pool is selected and is disinfected through quick lime after water in the pool is drained out in March every year, and after the water temperature is stabilized at 20 DEG C, 1,800 to 2,000 single male tilapia over-wintering fry with the weights ranging from 20 grams to 25 grams are thrown into the pool every 667 square meters, and 20,000 loach fry with the lengths ranging from 3 centimeters to 4 centimeters are thrown into the pool 30 days later. By means of food training, tilapias and loaches are fed in different feeding areas. Special mixed feed is thrown to feed the tilapias and the loaches two times everyday. After being bred for four to five months, the tilapias are caught in advance to be sold, the pool breeding density is decreased, and the growing period of the loaches is prolonged. The technology that the tilapias and the loaches are fed respectively in the same pool is adopted, rational combination is carried out according to the life habits and the feeding habits of the tilapias and the loaches, the aquatic water space is fully utilized, the bred marketable fishes are large in size and good in quality, and the purposes of promoting growth, increasing production and efficiency and improving benefits are achieved.

The invention belongs to the field of cultivation and particularly relates to a loach larva cultivating method. The method includes the following steps that firstly, breeding and oviposition are performed; secondly, eggs are put into an incubation pool to be incubated evenly, an oxygen boosting rod is placed beside the pool, the oxygen boosting rod is placed at the bottom of the pool after loach larvae get out of membranes, and the loach larvae are cultivated; thirdly, pond cleaning medicine is used for cleaning the pond, water filling and fertilizing are started three days later, and when the color of water of the pond is cultivated to be yellow green, the loach larvae are put into the pond; fourthly, before the loach larvae are put into the pond, the loach larvae are put into oxygen bags at first, the oxygen bags are put into the pool for buffering and then, the loach larvae are put into a net box; fifthly, milk powder and quail egg yolk are used as bait for feeding the loach larvae; sixthly, powder materials starts to be cast after seven to ten days. The rate of survival of the larvae cultivated with the loach larva cultivating method is improved to be more than 35%. By adjusting the position of the oxygen boosting rod, the density of the eggs can be adjusted, workloads are reduced, the cost in cultivating the larvae is reduced and economic benefits are boosted.

The invention discloses a separation method of fries and roes after hatching of loach fertilized roes, which relates to a loach fertilized roe hatching technology and comprises the following steps: (1) carrying out separation when mostly of or all loaches break through a membrane; and (2) adding a proper amount of trypsinase in a fry culture water body. The separation method quickly dissolves roemembranes and necrotic roes, prevents the roe membranes and the necrotic roes from winding fries, reduces the mortality rate of the fries, quickly separates the fries from other sundries, saves the labor time, improves the survival rate of the dries, reduces the consumption of the roe membranes and the necrotic roes on dissolved oxygen in the water body, keeps dissolved oxygen in water body adequate, reduces the labor consumption of the fries in the hatching process and improves the labor efficiency.
