1. Breeding freshwater shrimp is still a hot spot

my country’s freshwater shrimp market is mainly distributed in Guangdong, Guangxi, Jiangsu, Fujian, Shanghai and Zhejiang. The main cultured species include Macrobrachium rosenbergii, green shrimp, New Penaeus genus, Australian freshwater lobster, etc. Last year, vannamei shrimp were successfully cultured on trial in Guangdong, Fujian, Jiangsu and other places, making shrimp farming species more diversified.

At present, with the continuous expansion of the scale of freshwater shrimp farming, seed production is becoming more and more important. Overall, significant progress has been made in propagation technology for several freshwater shrimp species, and seed supply will not be a problem. For example, although the taste of Macrobrachium rosenbergii is slightly inferior to that of green shrimp, the price of about 40 yuan per kilogram has been accepted by most consumers; the key to maintaining a relatively stable selling price for commercial shrimp is to avoid centralized listings as much as possible, and farmers must make reasonable arrangements Production planning,

avoiding risks.

2. Risks and benefits of turtle farming coexist

The market price of soft-shell turtle has experienced from high price (200-300 yuan/kg) to low price (45-50 yuan/kg) ) and then to the development process that tends to be balanced (the current price is 90-100 yuan/kg). It can be seen that as the soft-shell turtle breeding technology improves, the varieties are optimized, and people's pursuit of natural and nourishing fashion is met, the price will stabilize and rise. Artificial turtle breeding is quietly emerging as a new industry in my country. Among them, golden turtles and snapping turtles are the species with the most publicity. Currently, the demand for seeds is large and the supply exceeds supply. However, the author believes that whether it is money turtles or snapping turtles, how much capacity they will have after entering the commodity market remains to be tested over time. Breeders should fully consider the potential risks of the market and should not blindly follow the trend.

3. Standardized sturgeon breeding has huge market potential

my country has eight species of sturgeon distributed in the Yangtze River, Heilongjiang and other water systems. The representative species include Chinese sturgeon and Acipenser schrenckii. , Acipenser dabricus etc. In addition, species introduced from abroad include Russian sturgeon, European sturgeon, etc. Regarding the development and utilization of sturgeon, my country's Wildlife Protection Law stipulates that breeding must be more than the second generation before operation, and stipulates that breeding must obtain an operation license issued by the fishery government department.

After several years of development in sturgeon farming, breakthroughs have been made in some key technical schools. Currently, it is a better time to invest in the sturgeon breeding industry from a market perspective. Sturgeons are large fish and generally reach sexual maturity in more than 10 years. They have strong limitations and will not rush into the fish industry. Sturgeon roe is known as black gold, and the price of sturgeon meat is more than 150-200 yuan per kilogram. Currently, there are no cultured sturgeons for sale in the domestic market, and the market is basically blank. If a breeding enterprise invests in sturgeon, it is believed that there will be a higher return on the premise of obtaining a business license.

4. The prospects for ornamental fish breeding are promising.

As the economic income of the people continues to increase, the quality of life has also been greatly improved. Breeding ornamental fish can not only beautify the family environment, but also adjust the traditional fishery production structure. In recent years, ornamental fish breeding in Guangzhou has continued to develop healthily, with an area of ??1,600 acres. The scale, variety, and output of ornamental fish have increased year by year. Among them, the three major series of goldfish, koi, and tropical colorful fish have reached more than 200 varieties.

5. There is great potential for cultivating small freshwater species

Small freshwater species generally refer to eels, loaches, pond lice, mountain groupers, whitebait, field snails, clams, mountain snails, etc. The above varieties can be cultivated in the courtyard by using the water in front and behind the houses of the village, as well as mountain springs and streams. They can be cultured intensively, purely, and intensively, and can be cultured with high yield and efficiency. Most of these small freshwater species can survive the winter in large quantities on the spot, stagger the seasons, and be put on the market according to demand in a balanced manner to obtain better economic benefits.

All in all, the market capacity and the following factors must be considered when choosing which species to breed:

(1) The price must be stable and rise;

(2 ) variety quality. While giving priority to breeding species, we also seriously consider the quality of the species.

For this reason, when selecting breeding sources, the water quality must be fresh, no pollution or less pollution, and the feed and drugs must be particular;

(3) Regional consumption habits. For example, carp (four major species of fish) is consumed inland, fresh is consumed in Guangzhou, and specialties are consumed in Hong Kong and Macao (turtle, turtle, eel, crab, shellfish, etc.);

(4) Regional economic development level . Generally speaking, the economic development level of coastal areas is higher than that of inland areas, that of plain areas is higher than that of mountainous areas, and that of cities is higher than that of rural areas. This determines that aquatic products in coastal areas, plain areas, and cities have higher sales prices, greater consumption, and higher quality requirements;

(5) Traffic conditions;

(6) Sales channels. In terms of transportation conditions and sales channels, coastal areas, plain areas, and urban areas are all better than inland areas, mountainous areas, and rural areas.

Farmers in various places must adapt to local conditions, be targeted, and base their efforts on their own (fisheries, companies) It depends on the marketing capabilities of funds and technology, and should not be rushed to avoid undue losses.

Experts explain the use of EM bacteria:

Take fish farming in ponds as an example. The water quality must be purified first. One day before stocking, 100 times of the dilute EM bacteria solution should be sprayed On the water surface, spray once every 15 days in the future. The frequency of spraying will be adjusted according to the water quality. The best effect is when it rains. Use 1 kilogram of EM bacterial liquid per acre. Fish feed can be treated with 200 times of EM bacteria liquid dilution, such as spraying on the pellet feed, with the spray moisture as the degree, and it can be used immediately after spraying.

Precautions for use are as follows: EM bacterial liquid is a brown translucent liquid with a sour taste and a slightly sweet aroma. You must pay attention to the smell when you first open the bottle. If the bottom of the container is slightly turbid and there is a small amount of white substance floating on the top, it will It is normal. Cap the bottle tightly after use and keep it sealed.

EM bacterial solution should be stored in a cool place away from light. The suitable temperature is 5℃~45℃. Beyond this temperature, the vitality of some bacterial strains will be affected, and the dosage should be increased appropriately.

The main functions of aquatic EM bacteria liquid:

1. Enhance the immunity and disease resistance of fish, shrimps, crabs, and sea cucumbers, and reduce the red skin, rotten gills, hard scales, and skin of aquatic animals The incidence of ulcers, malnutrition and metabolism, slow growth, emaciation and other diseases;

2. Rapidly degrade harmful substances in water, reduce nitrite, hydrogen sulfide, ammonia nitrogen content, and regulate water quality;

2. p>

3. Reduce the mortality rate during the transportation of fresh aquatic products. It is particularly effective in preventing the death of fry and larvae during transportation and extending the fresh life of aquatic products;

4. Reduce Residues of harmful substances in feed and aquatic animals improve the quality of aquatic products;

5. Improve feed conversion rate and reduce feeding costs.

6. Inhibit the growth and reproduction of harmful algae and fungi, promote the reproduction of beneficial single-cell algae, and maintain the microecological balance of the water body;

7. Stabilize the quality of the water body, prevent the aging of the water body, and improve Increase the dissolved oxygen content of the breeding water and increase the breeding density.

Water quality control

Take 10 acres of water surface as an example: dilute 10 kilograms of Qifu aquatic bacteria liquid 50 times with water, and then sprinkle it evenly on the water surface, or when placing bait , evenly mix the bacterial solution and bait according to the above proportions, and put them together. The usage cycle is generally 2-3 times a month. It is usually released in the morning on a sunny day.

Feed fermentation

Commonly used fermentable materials include: various types of residue, straw, grass meal, vegetable cakes, animal excrement, scraps, etc. You can choose the materials according to local materials . One kilogram of Qifu aquatic bacterial liquid can ferment 200 kilograms of bait (calculated based on dry weight).

The fermentation method is: dilute the Qifu aquatic bacteria liquid 100 times with water (that is, add 100 kilograms of water), then mix it evenly with the bait to be fermented, adjust the moisture to about 60, and then seal it to start fermentation , the fermentation time is generally 2-5 days.

The method to judge the humidity is: grab a handful of material with your hands and hold it tightly. Water stains can be seen on the seams of your hands, but no dripping. Stand up and release your hands. The material will fall to the ground and disperse. open.

Mixing and feeding

If you want to mix the Qifu aquatic bacteria liquid into the feed and feed it, you can add Qifu aquatic bacteria liquid according to 0.5 of the weight of the feed. The specific method is as follows:

To prepare 100 kilograms of feed, take 0.5 kilograms of Qifu bacterial liquid and dilute it with about 20 kilograms of water. Spray the diluted Qifu aquatic bacterial liquid while turning the bait, and mix evenly. Ready to feed.

Benefits and functions: Produce biologically active substances, which can reduce the feed coefficient, enhance the absorptive function and disease prevention and stress emergency response capabilities of aquatic animals, promote growth, significantly reduce the dosage of medicinal products, improve water quality, and make the water refreshing and unsustainable. It does not rot and smells bad, the visibility can reach 25~50 cm, and the water change time can be extended by more than 2 times. Full use can significantly reduce drug costs by more than 80%. Adhering to the use of Qifu aquatic bacterial liquid throughout the process can significantly increase the survival rate by nearly 30% and increase the efficiency by 20-35% (Penaeus vannamei gain 15-60% weight; the average weight gain of freshwater fish is 10-30%), and increase the spawning rate by 20-35%. Breeding cycles in similar environments can be put on the market 10 to 20 days in advance, with obvious comprehensive benefits and large growth rates.

Fermented organic fertilizer

Common fermentation materials include: various animal manure, plant stems and leaves, straw, grass powder, etc. Through fermentation, organic fertilizer can proliferate beneficial bacteria in large quantities, promote the reproduction of zooplankton, and avoid pollution of water bodies. The fermentation method is the same as the above-mentioned "bait fermentation" method. It is worth noting that if too much animal manure is used, the appropriate dosage per acre should be 100-150 kilograms, not too much.

Mainly aimed at large lakes, reservoirs and other breeding places.

(1) Pre-stocking treatment: dilute Qifu aquatic bacteria liquid 50 times and directly spray it on the spawning grounds of ferocious fish or wild fish to destroy their breeding and growth environment and control their population size.

(2) Feed with Qifu aquatic bacterial liquid fermented feed. For the fermentation method, please refer to the above "Feed Fermentation" column.

(3) Soak a honeycomb-shaped object such as a sponge in the diluent of Qifu Aquatic Bacteria Liquid (about 10 times) for 24 hours, then hang it in the middle of the cage, and use it through the swimming of the fish. The Qifu aquatic bacteria liquid continues to spread, and the Qifu aquatic bacteria liquid suspension is replaced every 7 days or so, which can completely change the water environment of the cage.

(4) Use Qifu aquatic bacteria liquid, fermentation material, and yellow soil in a ratio of 1:2:4 to make very sticky clumps, weighing 1 to 1.5 kilograms each, and dry them Finally, hang bags and baskets near the feeding materials so that the beneficial bacteria of Qifu aquatic bacteria liquid have a fixed residence to improve the purification effect, thereby improving and stabilizing the water quality. This mass is replaced once a month. Put 10 to 15 per acre.

After Qifu aquatic bacteria liquid penetrates into the water body, its group effect can kill or inhibit pathogenic microorganisms and harmful substances, adjust the breeding environment, increase the amount of dissolved oxygen (oxygen) in the water, and promote the normal development of the breeding ecosystem. The activated growth of bacterial flora and beneficial algae maintains the ecological balance of the cultured water body; mixed with bait for feeding, it directly enhances the absorptive function and disease prevention and stress resistance of aquaculture animals, and promotes healthy growth.

The photosynthetic bacteria in the Qifu aquatic bacterial solution can also use hydrogen sulfide, organic acids, and ammonia in the water to remove ammonium nitrite from the water through denitrification, thus reducing the excrement in the breeding pond. and residual bait pollution are purified, water quality is improved, and diseases are reduced.

The main functions of Qifu aquatic bacterial liquid are:

1. Reduce pathogenic microorganisms and undesirable algae; significantly enhance the immunity and disease resistance of cultured objects, reduce the incidence rate, and improve survival Rate. Users reported that Qifu Aquatic Bacteria Liquid can nearly double the survival rate of crab seedlings and increase the survival rate of Chinese grouper from 30% to more than 70%.

2. Increase the number of beneficial microorganisms. Zooplankton and beneficial algae are increasing on the water surface, especially red worms, which are increasing to cover the water surface.

3. Stabilize and improve water quality. The water body is fresh in color, not smelly or rotten, and has no odors such as hydrogen sulfide or ammonia. The visibility is long and stable at 25 to 50cm. The water change time can be extended by 2 More than times.

4. Fish and shrimp manure, pond bottom impurities and scraps will not turn into silt but become loose sand.

5. Promote growth and significantly increase the weight gain rate.

Practice has proved that under the same environment, after using Qifu aquatic bacterial liquid, it can be put on the market 10 to 15 days in advance, the average yield per mu is increased by 20% to 35%, the amount of eggs laid is increased by 25%, and the egg laying time is extended. Some tests have shown that after using Qifu aquatic bacteria liquid in new turtle ponds at room temperature, the egg-laying time is extended by nearly 70 days, and the hatching rate is better; the bait is not smelly, which improves the breeding environment.

Really large farmers or more professional farmers will choose high-quality microecological preparations to achieve considerable benefits and reduce costs and risks. A good product will always create benefits for customers instead of becoming a cost to them. On the contrary, choosing low-priced or diluted products may seem more economical on the surface, but in fact you are the one who really suffers. As long as you insist on using a good product for 1 to 3 months, you will find that the breeding benefits are obviously different.

Qifu Company was established in 2005. It is one of the earliest enterprises in China engaged in the research, development and production of EM bacterial starter. For 9 years, the company has always led the industry with its absolute product technology advantages and extensive market customer share. wind direction.
