There are ways to rejuvenate weak fish species in autumn.
Due to the hot summer climate, aging water quality and feeding management and other reasons, the physique of fish species raised by many farmers is weak. If these weak fish species are not rejuvenated in time when the autumn is high and cool, it is not conducive to the overwintering of fish species, and will greatly affect the annual output in the coming year. Therefore, it is very important to rejuvenate weak fish species in autumn. The methods of rejuvenation of weak fish species in autumn are introduced as follows: after the high temperature season of turning ponds and Qingtang in spring and summer, the general water quality is aging, the natural organisms are reduced, and the harmful bacteria are increased, which is not conducive to the fish.

What should be caught by fish species management in autumn?
Clear the pond. Transfer the fish to a pond that has been cleaned and sterilized for cultivation. If there are difficulties in the turnover of water sources and fishing ponds, all the fish species can be transferred out of temporary culture, then disinfect the original ponds with 75 kg ~ 100 kg quicklime per mu, and fertilize the water quality according to the conventional method, and return the fish species after the medicine disappears. Separate cultivation. Adjust the fish species according to different specifications, so that the specifications of the fish species in the same pond are the same. Large fish species have large food intake and strong grabbing power, just like small fish species in ponds, small fish will suffer from physical decline because they do not get enough feed. Fish over 16 centimeters

Pay attention to winter and spring fish
1. Pay attention to the tidiness of fish species. If the size of the fish species in the same fish pond is not neat, the ventral line is straight, the tail is thin, and the individual is thin, put into the fish cage for 30 minutes, that is, the activity is weak, slow, and some even have symptoms of illness. This kind of fish cannot enter fish pond to stock, also unfavorable long-distance transportation, can reduce stock density or transfer to fertilizer water to raise. If you are infected, you need timely treatment. 2. Pay attention to the length of fish species. When pulling nets, fish species jump violently

Autumn management techniques for fish species
Autumn is the peak season for fish species growth, because it is cold but warm and the water temperature is suitable. The management of fish species in autumn is the direct means to improve economic benefits. The author thinks that the management technology of fish species in autumn should pay attention to the following work. I. Clear the pond in time. After 23 months of breeding fish, the water quality will generally age, natural food will decrease, harmful substances such as hydrogen sulfide and pathogenic bacteria will increase. After autumn, fish species should be transferred to ponds that have been cleared of toxins for cultivation. Where water sources and fish ponds have difficulty in turnover, all fish species can be transferred out of temporary cultivation

Management of fish species in autumn
㈠ cleans the pond. After entering autumn, the fish species should be transferred to the pond which has been cleared and sterilized for cultivation, so that the fish species can survive the winter safely. Where there are difficulties in the turnover of water sources and fish ponds, all the fish can be temporarily reared, disinfect the original pond with 75-100 kg of quicklime per mu, fatten the water according to the conventional method, and return the fish to the fish after the drug disappears. Separate cultivation of ㈡. It is necessary to make sure that the specifications of the fish species in the same pond are consistent. Large size fish species have large food intake and strong grabbing power. If small size fish species are put at the same time, small size fish species will cause.

How to identify high quality fish species
"half the profit is good for planting, and half the grain is good for seedlings." Strong and good quality fish species is not only an important factor to improve the survival rate of fish species, but also an important basis and guarantee to increase fish production and economic benefits. High-quality fish species should have: appropriate specifications, neat, robust and harmless, lively action, strong food grabbing power, specifically to identify high-quality fish species can be summarized as "three look and one sampling". A look: the specifications of fish species in the same pond and the same fish pond should be neat and uniform, with little difference in body length and weight, on the contrary, there is a large individual gap.

Key techniques for breeding fish species in autumn
Autumn water temperature is appropriate, is a good season for rapid growth of fish species, do a good job in autumn fish species cultivation is very critical, autumn fish species cultivation technology points are as follows: 1, clear pond after 2-3 months of fish species cultivation pond, water quality aging, natural bait reduced, harmful substances and pathogens increased. Therefore, after autumn, fish species should be transferred to ponds disinfected by pond cleaning for cultivation. Under the condition of relatively insufficient water and fish ponds. All the fingerlings can be transferred out for temporary cultivation, and 75-100 parts of quicklime are used for each mu of the original fingerling pond.

Measures to strengthen autumn breeding of fish species
Autumn water temperature is generally between 20~30℃, it is a good time for fish growth, if autumn does not grasp the breeding of fat fish species, to the cold winter, most fish species will die due to thin physique, the average survival rate is often less than 60%. Therefore, strengthening the autumn cultivation of fish species is a top priority for farmers. The specific cultivation measures are: disinfecting and clearing the pond, transferring to the fish pond where the fish species are cultivated in Xintang. After several months of cultivation in spring and summer, the water quality is gradually aging, and the dissolved oxygen and food organisms are reduced.

How to distinguish high-quality fish species
A look at the specifications of fish species the specifications of the same kind of fish in the same pond should be neat and uniform, with little difference in body length and weight. On the contrary, the overall survival rate of poor fish species with large individual gap and uneven quality is often very low due to predation, mixed germplasm, poor feeding and other reasons. Second, look at the body color of fish species. The body color of fish species is bright and full of luster. Different species and different feeding methods have different body colors. Generally speaking, the back of high quality silver carp should be silver gray, the side of body and abdomen should be silver white, and the body color of high quality grass carp should be light.

Due to the water system, fish species should be put in reasonably.
In an activity of science and technology going to the countryside, the author learned that the output and benefit of many fish farmers were not ideal in the process of fish culture in ponds over the years. the main reason is that the fish species are not reasonably matched according to the fish diet and habits, and the species is single, the quantity is too large and the size is small. This situation exists more or less all over the country, and the end of the year and the beginning of the year is the season for the release of a large number of fish fingers. in order to make full use of the water body, put the fish species reasonably and increase the yield per unit area of the water body, the fish species will be put in reasonably according to the water system.

Key measures for cultivating large size fish species
Fish species are the material conditions for stable and high yield of adult fish. Practice has proved that large-size fish species have strong ability to adapt to the environment, escape from enemy damage, disease resistance and feeding ability, so the survival rate is high, the size of water is large, and can achieve the goal of high yield. In order to cultivate large-scale fish species, in addition to "four-fixed" feeding, "three-look" fertilization, daily pond patrol and fish disease prevention and control, the following measures should also be taken: 1. Add new water to improve water quality. "when the water rises by an inch, the fish grows by three cents" and "the wide water raises the big fish". In the process of feeding

Five points for attention in fish species management in autumn
The water temperature is suitable in autumn, which is the peak season for fish growth. Fish species management should do a good job in the following five tasks. 1. Clear the pond.
