Description
Technical Field
The invention relates to the technical field of aquaculture production, in particular to a high-efficiency culture method of high-quality fries with good environmental adaptability.
Background
Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under artificial control, and has modes of rough culture, intensive culture, high-density intensive culture and the like. The rough culture is to put seedlings in medium and small natural waters and to culture aquatic products such as fish in lakes and reservoirs, shellfish in shallow seas and the like by completely relying on natural baits. Intensive culture is to culture aquatic products such as pond fish culture, net cage fish culture, fence culture and the like in a small water body by using bait casting and fertilizing methods. The high-density intensive culture adopts methods of flowing water, controlling temperature, increasing oxygen, feeding high-quality baits and the like to carry out high-density culture in a small water body so as to obtain high yield, such as flowing water high-density fish culture, shrimp culture and the like.
According to the development of the breeding industry, many people start breeding, especially in the breeding of fish, the demand of fish on the market is large, because many people such as the old can carry a fish, and the fish is often seen at home and in restaurants, so that many people breed fish, which feel that the fish is a good way to get rich, so that many people with achievements are created in the breeding of fish, some fry breeding is also important, because some fish eaten usually are bred through fry breeding, so that the breeding of fry is very important, because the fish cannot grow big fish if the fry breeding is not good, and the farmer often dies the fry bred by himself, and the reason for death can not be found, which is often caused by unscrupulous breeding technology, at present, the breeding technology of some farmers falls behind, so that the mortality rate of fry breeding is high, the breeding cost is increased, and therefore, an efficient breeding method of high-quality fries with good environmental adaptability is provided.
Disclosure of Invention
The invention aims to solve the problems that farmers often die of self-cultured fry and cannot find out the cause of death in the prior art, which is often caused by unscientific culture technology, and the culture technology of some farmers falls behind at present, so that the death rate of fry culture is high and the culture cost is increased, and provides a high-efficiency culture method of high-quality fry with good environmental adaptability.
In order to achieve the purpose, the invention adopts the following technical scheme:
an efficient culture method of high-quality fries with good environmental adaptability comprises the following steps:

s3: selecting a fish pond: the area of the pond is 3-5 mu, a plurality of grids which are arranged in a crossed manner are arranged in the fish pond, and an incubator is arranged in each grid;
s4: disinfecting the fishpond: pumping out water in the pond water by a water pump, then dredging until the depth of sludge is 0.4-0.6 m, insolating for 3-5 days, and then spreading quicklime and disinfectant water in the pond for disinfection;
s5: introducing running water into the pond: an opening communicated with an external water source is formed in the dam of the pond, so that the external water source can enter the pond;
s6: pre-throwing the fry: firstly, trying to put 30-60 fish fries into an incubator in a pond, observing day and night, observing the activity of the fish fries, and observing whether the floating head condition is abnormal or not, such as the phenomena of scorching, uneasy floating head struggle and cross-swimming at four places, which indicate that the pond cleaning medicine is remained, and the fries can be put after the medicine effect is completely disappeared;
s7: putting the fries formally: if the fry put into the incubator at the current period is not dead in large batch, the healthy fry can be put into the incubator formally, and the fry tail number in each incubator is between 350 and 600 tails;
s8: detecting the water quality: the water quality is detected every 3-7 days, and once the water quality is found to be in problem, the water needs to be changed immediately.
Preferably, in S1, the fish fry is selected to be hatched for 4-7 days, the fish ticket has strong air inflation swimming capability, the specification is neat, the high-quality fish seeds are kept in good order, objects are inserted into the container for holding the fish, the high-quality fish fry can quickly swim and scatter after being disturbed, the poor-quality fish fry is slow in response, in addition, water in the pot can be poured for observation, the high-quality fish fry can strongly struggle and bounce forcefully, the head and the tail can bend into a ring shape, the poor-quality fish fry is attached to the bottom of the pot and struggle without force, and only the head and the tail shake.
