I personally think that as a fish farmer, both love fish and love to eat fish, if you do not love what you do enough, then you will lack the spirit of research, work hard and concentrate on doing this, and the effect will be good and bad. If you don't love agriculture, how can agriculture reward you?
I like crucian carp, crucian carp in two weights, fried in oil until crispy and crunchy. In particular, crucian carp raised in rice paddies is more fragrant. Another way to eat crucian carp is to cook soup, crucian carp tofu soup color milk white, rich in nutrition, sweet taste. When my daughter-in-law is pregnant and with children, she often drinks crucian carp soup, and the fish left over from her soup can only be eaten by me.
Crucian carp is also favored in the market, consumers like its nutritious, delicious characteristics, and some people like it not much thorn. The part of crucian carp with fewer spines is mainly in the two ribs, but this part of the meat is too thin and too little, so the best way to eat it is to eat it directly, or braise it into a sour and spicy mouth.
The more people who eat, the more people who raise them. Farmers value the characteristics of crucian carp with strong adaptability and easy farming. The more people raised, the more problems encountered, because the environmental conditions in which everyone is located are different, and the problems encountered in breeding are also different.
In this article, I will combine my own and some fish breeding veterans to share with you the experience of 7 crucian carp farming techniques for your reference and discussion.
<h1 class="pgc-h-arrow-right" > first, choose a good breed of crucian carp</h1>
What is a good breed of crucian carp.
Good breeds are colloquially known as excellent breeds. Specifically, the fine breed of crucian carp is an aquatic scientist according to the market demand and breeding needs, different species, different characteristics of crucian carp hybridization, breeding, such as our farmers need to grow fast, less sick crucian carp species, aquatic scientists according to the two needs of farmers, to breed, hybridize we need crucian carp species.
Why choose good seeds.
The purpose of our fish farming is to increase production and income. Now the crucian carp market is basically stable, the market price will not fluctuate greatly, the buying and selling bilateral basically tends to be saturated and stable, in such a situation, only by reducing the cost of breeding and improving the efficiency of breeding can we get more benefits. How to reduce the cost of breeding, improve the efficiency of breeding, the use of good seeds is a good way. Fine breed crucian carp through specific selection, with high feed conversion rate, strong disease resistance, fast growth and development of the characteristics, these characteristics of them can help us reduce the cost of breeding, improve the efficiency of breeding. Assuming that the situation such as the area under cultivation is the same, at the same price, if our production is higher than others and the cost is lower than others, then we are more profitable than them.
What are the good seeds.
Such as heterogeneous silver carp, Pengze carp, abundant carp, Xiangyun carp, white carp, etc., it has the characteristics of fast growth and strong disease resistance.
<h1 class= "pgc-h-arrow-right" > second, to use fertilizer aquaculture</h1>
Crucian carp is an omnivorous fish, which can eat vegetable leaves, melon leaves, corn, wheat bran, aquatic grasses and other plant foods, and also eat animal bait such as miscellaneous fish meat, snail meat, and earthworms. Aquatic insects, phytoplankton, and zooplankton in the water are also food for crucian carp. The fish pond for breeding crucian carp should be kept in a "fat" state, and there are many phytoplankton and zooplankton in the fertile water, and crucian carp can make full use of these foods to grow and develop, thereby reducing our feed costs.
Suppose we had to spend the same amount of time raising crucian carp to 1 pound, the lean water fish pond would feed more than the fat water. Fertilizer water can help you save money on feed.
Before releasing crucian carp fry, it is necessary to fertilize 5-7 days in advance and fertilize the water; after the seedlings are released, it is necessary to observe the changes in water quality at any time, if the transparency of the water is large and the water quality is thin, it is necessary to topdress in time. Bio-bacterial fertilizers can be used, which are both fatty aquatic products and can also be provided to crucian carp food.
<h1 class= "pgc-h-arrow-right" > third, to be domesticated</h1>
Fish farmers have found that fish must be domesticated to feed. Some fish keepers whistle, or slap a few fingers, clap a few palms, and the fish swim over to concentrate on eating. The advantage of this is that on the one hand, each fish can eat the bait, and on the other hand, we can observe the eating and health of most of the fish in order to make adjustments to the farming strategy.
Fish ponds generally need to be set up with food tables. Crucian carp is a demersal fish, and crucian carp needs to be domesticated to go up to the table to eat feed. When buying crucian carp seed, ask the manufacturer if it has been trained to eat. However, most fry breeding farms may not have a food platform, although the fry have been domesticated, but not necessarily on the food table to eat, so it is still necessary to domesticate, and the fry from the original fish pond to another fish pond, the environment has changed, the area of the fish pond is also larger, but also need to adapt to the eating environment through domestication.
The feeder has its own domestication effect, here we will not talk about it, talk about artificial feeding and domestication. Within a week after the seedlings are released, with the food table as the center of the circle, the material is first sprinkled five meters away from the food table, and the barrels, pots and other utensils are rhythmically beaten with wooden sticks when the material is sprinkled, as a sound to guide the fry to come to eat. Then, in the same way, every 3 days, sprinkle the feed 1 meter closer to the food table until all the fry swim to the table to eat.
< h1 class = "pgc-h-arrow-right" > four, a small number of multiple feedings</h1>
Crucian carp and carp have similarities in terms of feeding habits and living habits, but they are also different. Crucian carp seems to be more like a "little family jasper". One property of crucian carp is that it eats less at a time. However, if the fish wants to grow, it needs food to give it energy, and they are swimming all the time, and they are constantly consuming energy, so they need to supplement food.
According to this characteristic of crucian carp, we can use a small number of feeding methods when feeding. The fish farmer I know told me that when he raised crucian carp, the fry were fed 5 times a day, and the adult fish had to be fed 4 times a day.
<h1 class= "pgc-h-arrow-right" > five, the seedlings should be released at one time</h1>
This recommendation applies to all types of fish farming.
Generally, during the period from Qingming to the summer solstice, the temperature gradually rises, and everyone slowly begins to release fish fry. Because of the difference in climate from place to place, my recommendation is to release seedlings at a water temperature of more than 15 degrees Celsius, and choose to release seedlings when the water temperature is stable on continuous sunny days. In this way, the survival rate of seedlings is high.
For the same type of fry, release them at once and avoid irregular specifications. I met a fish farmer who, when he raised crucian carp, put fry in the pond three times in a month and a half. In this way, the time span of the fry before and after is large, and the size of the fry is not neat; the second is that when feeding the feed, it will be chaotic because of the size of the fish; the third is that the small fish cannot grab the big fish; and the fourth is that the multiple batches of fish may bring germs.
It is recommended to buy enough seedlings at one time, if the number of fry in the fish hatchery is not enough, it is better to wait until the number is enough to buy seedlings.
Here is a problem to pay attention to, we raise crucian carp will be paired with silver carp and grass carp, these fish do not put in the same time as crucian carp, because it will affect the domestication of crucian carp. When breeding different species, it is possible to stagger the time to release seedlings, such as silver carp and grass carp after 1-2 months.
<h1 class = "pgc-h-arrow-right" > six, give crucian carp calcium and vitamins</h1>
This technique was told to me by a fish farmer who regularly supplements crucian carp with calcium and vitamins, and crucian carp gets fewer diseases and grows faster.
Vitamins are familiar to everyone, and you can buy vitamins for aquatic products and mix them in the feed to feed them.
The problem of calcium supplementation is also very simple, regular sprinkling of quicklime, it has the effect of calcium supplementation, because quicklime contains calcium, and sprinkling quicklime can also disinfect the water body and play a role in preventing diseases. Of course, it is also necessary to buy calcium supplement products from fish pharmacies and mix them in feed, so that the effect is better.
< h1 class = "pgc-h-arrow-right" > seven, winter should also be properly fed</h1>
This recommendation is not suitable for places where fish ponds can freeze in winter.
In the south, in some places, the winter fish ponds do not freeze, and the water temperature at noon can be 5-8 ° C, at this time the fish are not completely out of food, and they will also find food to eat when the water temperature is right. We also found that the fish of friends still look very fat after a winter, while the fish of some friends are the opposite, and the fish is emaciated after a winter. In addition to the problem of good and bad fattening work in autumn, we recommend that fish breeding friends combine their local climate conditions and feed a small amount of fish in winter, so that they can preserve their fat.
If your local winter climate is good, you can do this by feeding a small amount around noon on a sunny day and feeding high-quality concentrate.
In short, when we are breeding, we pay more attention to targeted management according to the characteristics of crucian carp, and we will do better than others when we find out some ways.
