Tips about future sustainable fisheries management development

 Today, we will introduce some knowledge about the fishery.

The global fishery production has been slowing down year by year or affected by the increasing awareness of sustainable development of fisheries, which is also in line with the expectations of the United Nations Sustainable Development Goal 14: "Conservation and sustainable use of oceans and marine resources for sustainable development", The development trend of the world's fisheries in the future is generally reflected in the following three aspects:

Ecosystem Sustainability

In the future, international, regional and national fishery management legal systems and organizational models will continue to increase and improve, becoming the guarantee and foundation for the smooth cooperation and management of global sustainable fisheries. Since the adoption of the Code of Conduct for Responsible Fisheries in 1995, the United Nations and related organizations have issued a series of international guidelines and technical specifications accordingly, and the number of countries developing responsible aquaculture and establishing legal frameworks has also increased from less than 40 in 2011 to 2018. more than 90 countries.

Another sustainable development direction of the modern ecosystem is the improvement of technological innovation and informatization. First, the establishment of a comprehensive database of fisheries and aquaculture has made it possible to connect data on production, fishing vessels, trade, and employment. Based on this, information systems and partnerships have been established among various fisheries-related organizations, such as the Fishery Resources Monitoring System (FIRMS), the Aquatic Genetic Resources Monitoring System, and the Aquatic Species Introduction Database. Quantity and product legality monitoring, biological genetic research, fishery resource management, information exchange and sharing, etc. Now, more and more farmers use the dry type fish feed pellet machine.

Biodiversity Sustainability

The sustainability of biodiversity is an important part of maintaining marine ecosystems. At present, about 24.2% of fish stocks in marine fisheries are in a state of overfishing. It will be imperative to promote sustainable transformation of marine fishery fishing methods in the future. action. For example, among the seven species of tuna with high economic value, about 33.3% of the population is currently overfished. In the future, purse seine and trawling will continue to be replaced by longline fishing. Through the popularization of improved fishing gear fishing methods, bycatch will generally be reduced by about 25%-50%, and help to retain and select high-value species, improve economic efficiency and environmental sustainability.

Sustainable Fisheries Livelihood Development

In terms of sustainable fishery livelihoods, the United Nations has designated 2022 as the "International Year of Artisanal Fisheries and Aquaculture", and the participation of small-scale producers in sustainable resource management will become mainstream. Correspondingly, neglected human and labor rights in the fisheries and aquaculture value chain will also be emphasized in the future, and social security systems, laws and regulations at the national and international levels will be further implemented.

Aquaculture is the leading force in the global fishery in the future. As a major aquaculture country, China will continue to transform from extensive to intensive, adopting eco-friendly technological innovations to reduce production capacity and improve efficiency.

Kind tips:

The FAO forecast results are based on the following specific assumptions: future macroeconomic environment; international trade rules and tariffs; frequency of events and impact on resources; immunity from tsunamis, tropical storms (cyclones, hurricanes and typhoons), floods, Impact of severe climate events; no outbreaks of new fish diseases; fisheries management measures including fishing restrictions; and no market shocks. China's policy implications (the 13th Five-Year Plan) are also taken into account.

The world fishery in 2020 is still full of unknowns and challenges, but as people's awareness of sustainable development gradually increases, it is expected to bring a more promising future to the industry.

Complete and Balanced Dog Food Diets Content

Healthy pets lead to happy pets, they need balanced amounts of protein, carbohydrates, fats, oils. 

Healthy pets lead to happy pets. Just like with humans, meals that include balanced amounts of protein, carbohydrates, fats, oils, along with essential minerals and vitamins are key to a dog’s long-term health. But unlike their human owners, dogs can't choose from an array of fruits, vegetables, meats and grains every day. 

Instead, dogs typically eat the same food at each meal, which is why picking a food that uses scientific research to formulate a precise balance of nutrients is important. If you understand what is in dog food, you're likely to pick the highest quality food for your four-legged friend, which is essential to many long, memorable years of companionship. It's important for dog food is "complete and balanced".

And you should learn about the floating fish feed production line which will help you a lot in your making food for your pet.

Complete and Balanced Dog Food Diets Content

Protein

A well-balanced dog food should contain a good source of high-quality protein (which provides essential amino acids) as one of the first ingredients. Protein is needed for growth, development and a healthy immune system.

Carbohydrates

Carbohydrates supply Fido with the energy he needs to get through his day.They also contain fiber which converts to glucose in his body.

Raw vegetables

Good sources of carbohydrates include most grains, fruits and vegetables.

Fats

Fat is a valuable source of energy and is also needed to keep your puppy/dogs; coat and skin healthy. In commercial dog food formulas these may be found in muscle meats, or as animal fat or vegetable oils. Again, a specified source of animal fat such as chicken fat; is good, the more generalized; animal fat is not.

Vitamins And Minerals

These are vital to your pets: health and it's important that they're supplied in the right quantities and in the correct ratio.

Not so long ago there were far fewer dog food choices, and most dogs and puppies ate basically the same food. Today, the industry is much more specialized as scientists and nutritionists have come to realize that different dogs have different nutritional needs.

You'll find puppy and adult food for large breeds, small breeds; giant breeds; senior dogs; active dogs; overweight dogs; dogs with certain medical conditions; breed-specific dog foods and much more. Each group has very unique and individual requirements which need to be met if they’re to stay healthy.

The ways of eworming chickens

 Deworming method:

1. In the process of first-line treatment, we often classify them into one category. Now the levamisole and other anthelmintics on the market can achieve very good prevention and control effects.

2. For free-range chickens, deworming starts at about 50 days of age. At this time, the chickens have basically been cold, and it is easy to ingest the eggs in the free-range state. At this time, the first deworming will begin. After the first deworming, 7 days later, another deworming will be carried out to ensure that the eggs in the chicken body will regenerate adults and be killed more thoroughly.

 

3. In the future, deworming will be performed every 40 days or so. This kind of flock will be healthier and grow evenly in the later period, and the farmers will reduce a lot of unnecessary damage.

 

4. Tobacco leaves repelling chicken insects: Feeding chickens with tobacco leaves soaked in water can repel chicken roundworms and chicken tapeworms. The method is: take an appropriate amount of yellow tobacco leaves, dry and crush them, add 2 kg of water to 1 kg of tobacco leaves and soak for one day and night, and wait until the tobacco leaves are reddish-brown in water. Be careful not to feed the chickens 14 hours before feeding the tobacco powder. For the first 4 hours, you can feed 2 spoons of 1% salt water and an appropriate amount of water. Then, fill each chicken with 5 ml of tobacco powder, 3 days apart, and then feed according to the above method. A few times, it can get rid of chicken roundworms and chicken tapeworms.

 

Treatment measures:

For roundworms and nematodes, use albendazole ivermectin powder and mix it evenly with the feed according to the usual amount. Allow chickens to eat or drink freely. The effect of taking the medicine on an empty stomach is better. This method has ideal deworming effect and is safe. During the deworming of chickens, the feces of the chickens should be cleared in time and accumulated and fermented to kill the eggs. At the same time, thoroughly clean and disinfect the chicken house, utensils, and grounds.

 

Deworming chickens

In addition, in order to prevent the occurrence of chicken parasitic diseases, we must pay attention to the management of the environmental sanitation of the chicken house. When medication, we must choose a wide range of deworming drugs. Try to use small doses that can be used for group deworming to prevent the worms from developing resistance. Sex, improve insecticidal effect.

 

And if you have a chicken farm, maybe you can go to see the feed crushing machine, feed drying machine, which will be used in the chicken feed processing line.

Have a good day!

Introduction of the poultry ring die feed pellet machine

Do you need some ways about the poultry feeding? Come to learn about the ring die feed pellet machine.

Our chicken ring die feed pellet machine is a type of feed machinery for commercial purpose, belonging to the industrial pellet mill. The basic function of a ring die feed pellet mill is to produce high quality pelleted feeds for chicken, cattle, pigs, horse, duck etc. in large scale feed pellet plant.

Ring Die Pellet Machine application:

Mainly suitable for medium-and small-scale farming professional households and other processing of various livestock and poultry and aquatic pellet feed can reduce the cost of aquaculture. Animal feed machines can be used for raising rabbits, chickens, ducks, geese, fish, pigs, cattle, sheep, aquatic products, and so on. 

Purpose of feed quenching and tempering

A. Conducive to feed granulation molding

B. Improve feed digestion and absorption rate

C. Increasing the stability of aquatic pellet feed in water

D. Increasing the output of the granulator and reducing the power consumption E. Reducing the wear of the stamper and the pressroll

F. Destruction and killing of harmful factors

G. 2~3 liquid components can be added during quenching and tempering

So come to see the lima animal feed machines.

Tips of tilapia breeding and seedling preservation

There are two methods of clearing the pond: dry clearing and water clearing. Due to limited conditions, wet clearing is generally adopted here. The specific plan is that 15-20 days before the seedlings are placed, 5-10 cm of quicklime with water can be used for disinfection, and the general dosage is 40-80 kg/mu. After 2-3 days, use a dense mesh filter to inject water, and the water depth should be 2 meters.

It is very important to cultivate a pond of good water, which is related to the success rate of seedling placement. If the water quality is too thin, the water body will lack the stability and nutrients needed for the growth of fish fry. At this time, it is recommended to use "Algae Ansheng" to cultivate beneficial algae such as diatoms and green algae. Use the "Double Profit" package every two days (1 pack of "Limiaoduo" + 4 bottles of "Lijunduo" + 10 catties of brown sugar + 400 catties of water, fermented for 1-2 days) to improve the carbon-nitrogen ratio of the water body and maintain the pond biological stability. 

Note: Do not use large bags of granular organic fertilizer or chemical fertilizers. Avoid the rapid growth of algae and the single algae phase, which will cause algae inversion, dirty bottom, water change, high pH value, bubble disease, etc.

10-15 days after water cultivation, the zooplankton, phytoplankton, and microorganisms in the water have reached a balance. The typical sign is the appearance of cladocerans in the water body. This kind of water is stable, has strong self-purification ability and normal indicators. This is the best time to put seedlings. good time. The fish feed extruder machine in fish feed production line is very important.

The density of tilapia seedlings should be 20,000 to 30,000/mu. If the density is too high, the bait organisms in the pond will be insufficient, and it is not conducive to insect and disease prevention. The temperature difference between the seedling bag and the pond should not exceed 2 °C. Generally, the seedling bag is placed in the water until the temperature difference is lower than 2 °C, and then the seedling bag is opened and the seedlings are placed. The fry is easy to cause mechanical damage during the operation. 

After the fry are placed, the use of disinfectants with high safety and low irritation (such as "Yongle iodine") can reduce the probability of the fry getting sick.

1. Feeding "Benefit Duo" Suspended bait "Benefit Duo" can be fed from the start of seedling release, which has an attracting effect and is helpful for fry opening and nutritional supplement; it can also cultivate zooplankton, stabilize water and prevent air bubbles. Purify water body; use for 7-10 days, the effect of strengthening seedlings is outstanding. Maybe you will use the feed crushing machines, which will help you a lot in feeding your fish.

2. Multi-use live bacteria Using the "Double Profit" package can not only increase the bait for fry, but also supplement the beneficial flora of the pond, speed up the circulation of substances, stabilize the water body, and prevent and control bubble diseases.

3.Under normal weather conditions, 7-10 days after the seedlings are released, the oxygen consumption of the fry will increase, which will cause hypoxia and affect the survival rate of the fry. It is recommended to turn on the aerator at around 12 o'clock in the evening to prevent hypoxia and increase oxygen. It can also stabilize water bodies.

The difference between feed pellet machine and feed extruder

Feed pellet machine: feed pellet machine, widely used in large, medium and small aquaculture, grain feed processing plants, livestock farms, poultry farms, individual farmers and small and medium-sized farms, farmers or large, medium and small feed processing Factory use.

Feed extruder: This series of dry and wet extruders are suitable for large, medium and small farms, feed factories and food factories.

So today, we will learn the feed pellet machine and feed extruder.

1. Different in nature

Feed pellet machine: feed pellet machine (also known as: pellet feed machine, feed pellet machine, pellet feed forming machine), belongs to feed pelleting equipment. It is a feed processing machine that uses corn, soybean meal, straw, grass, rice husks, etc. as raw materials, and directly presses the raw materials into pellets after crushing the raw materials.

Feed extruder: Feed extruder is a kind of extruder, mainly used for food extruding, livestock and poultry feed or for extruding a single raw material, and can also be used as the pretreatment of raw materials in the production of vegetable oil and drinking wine.

2. Different scope of application

Feed pellet machine: feed pellet machine, widely used in large, medium and small aquaculture, grain feed processing plants, livestock farms, poultry farms, individual farmers and small and medium-sized farms, farmers or large, medium and small feed processing Factory use. And you can go to see the ring die chicken feed pellet machine.

Feed extruder: This series of dry and wet extruders are suitable for large, medium and small farms, feed factories and food factories. Maybe you can see the dry type fish feed pellet machine.

3. Different features

Feed pellet machine: simple structure, wide adaptability, small footprint and low noise. Powdered feed and grass powder can be granulated without adding a little liquid, so the moisture content of pelleted feed is basically the moisture content of the material before granulation, which is more convenient for storage.

Feed extruder: novel design, compact structure and high production efficiency. Reliable work, sturdy and durable, low failure rate, easy operation and maintenance. Simple and convenient to use, stable transmission, low noise.

Breeding Mode of Tilapia

 Hello:

1. Intensive cultivation mode

 

The intensive cultivation mode of tilapia developed rapidly in the past few years. Intensive cultivation, that is, pure tilapia cultivation, can produce more than 5,000 kilograms per mu, creating a lot of tilapia myths. The representative areas of the intensive breeding model are tropical and subtropical breeding areas such as Wenchang, Hainan and Nanning, Guangxi. Ponds need to be equipped with strong oxygenation capacity, and ponds with good conditions even have sewage systems.

 

Hainan, taking advantage of its unique climate, can raise three fish a year; Nanning, on the other hand, relies on its advantages in the domestic market, and the price of fish has been relatively strong. Tilapia in intensive culture mode grow fast and yield high, so they are highly respected by farmers in the two places. In addition, the peak market period of tilapia is from October to December, which is also the time when the price is the lowest. Tilapia under the intensive culture mode can be listed one month earlier, and farmers can make a time difference to avoid the peak fish output and impact the fish price.

 

However, in the past two years, intensively cultured tilapia has faced the double test of streptococcosis and weak exports. Under the circumstance that the market situation in the past two years is still unclear, many large tilapia farmers are still in a wait-and-see mood. 

 You should learn the fish feed pellet production line.

2. Tilapia-shrimp polyculture mode

 

The tilapia-shrimp polyculture model can be regarded as a relatively classic breeding model, which is also due to the frequent occurrence of shrimp diseases and the downturn of the tilapia market in recent years. This pattern is distributed in Taishan, Zhuhai, Zhanjiang and Maoming in Guangdong.

 

The tilapia-shrimp polyculture model is dominated by tilapia and supplemented by prawns. The two complement each other and improve the ability to resist risks. Farmers generally start to label rough tilapia fry and shrimp fry in the middle and late March. The seedling density of tilapia is 2500-3000/mu, and the shrimp fry is 20000-30000/mu, mainly the second generation. After the standard thickness, the size of tilapia fry reaches 50/catties, and when the size of shrimp fry reaches 800/catties, tilapia and prawns can be mixed in ponds. There are also some farmers who directly put shrimp fry in the tilapia fry pond, and then replenish the fry in a timely manner during the breeding process. Farmers with sufficient ponds can start preparing the standard thickness of the second crop in the middle of the first crop to achieve the goal of maximizing aquaculture efficiency. Tilapia is fed in the whole process, while vannamei shrimp does not feed or feed less. Taking advantage of the omnivorous characteristics of prawns, the utilization rate of feed and the purification capacity of ponds are improved, and the risk and cost of breeding are reduced.

 

The prawns can be harvested at the beginning of June, and the land cages are used for catching. The annual output per mu is about 200 catties. Calculated at an average price of 15-20 yuan/catties, the per-mu output value of prawns is 3000-4000 yuan, which can offset most of the tilapia. feed expenditure. Tilapia can be marketed in batches in mid-September, with a bait coefficient of about 1.3 and a yield of 2,500-3,000 catties per mu. Taking advantage of the high value-added characteristics of prawns, this model can greatly improve the farming income of tilapia.

 

3. Intensive breeding of large-sized tilapia

 

In recent years, the market for large-sized tilapia of 3-4 catties has been very stable, with an average price of about 10 yuan / catty, and the profit margin is not small. It is chased by some farmers. The breeding areas are mainly concentrated in Zhuhai and Foshan. Near high-consumption cities. In this mode, the seedlings are generally invested in March, and the amount of seedlings per mu is 3000-4000 (size 7-8). After 3 months of breeding, farmers can choose to remove some commercial fish or separate ponds for breeding to speed up capital. Turnover and reduce farming risks in hot seasons. After raising until the end of the year, the size of tilapia reaches 3-4 kilograms, and farmers can produce fish in batches according to market conditions. Taking the farmers in Pingsha, Zhuhai as an example, under this model, the annual output of tilapia can reach 6,000 kilograms, and the profit per mu is as high as 12,000-15,000 yuan.

 

Although profitable, this farming model is only suitable for farming areas close to wholesale markets or urban consumer groups. These areas not only have strong consumption capacity for large-sized tilapia, but farmers can also directly connect with the market to obtain greater profit margins.

 

In addition, raising large-sized tilapia must overwinter, because the price of tilapia is the highest after the year when the green and yellow are not in contact. Whether it can survive the winter has become the most concerned issue for tilapia farmers. Therefore, this model is only suitable for ponds with winter sheds and sufficient groundwater or geothermal heat. This model has a long breeding cycle and high cost. Farmers should choose according to their own pond environment and market environment, and do not blindly follow the trend. 

4. Three-dimensional breeding mode

 

Stereoscopic farming includes traditional fish-duck polyculture and fish-pig polyculture, which are mainly concentrated in eastern Guangdong and inland large-water aquaculture areas. Taking the mixed breeding of fish and ducks in eastern Guangdong as an example, the stocking density of tilapia is 800-1000 tails/mu (size 8-9), and it is also matched with filter-feeding and omnivorous fish such as bighead carp, silver carp and dace. kind. Feeding open feed in the fry stage to improve the survival rate, no feed or less feed in the middle of the breeding period, when the fish reaches a size of more than half a catty, they start feeding tilapia feed for fertilization, and some farmers will feed duck feed when they are waiting for the price of fish . The bait coefficient of the whole process is about 0.6-0.8, and the breeding cost is 2-3 yuan/catties.

 

According to an industry personnel analysis, the cost of intensive tilapia culture is generally 3.5 to 4 yuan per kilogram, polyculture is 3 to 3.5 yuan per kilogram, and the cost of three-dimensional culture is 2 to 3 yuan per kilogram. Under the current situation, the first two breeding modes are loss-making transactions. Therefore, for now, three-dimensional farming is still the best farming mode for tilapia farmers to avoid market risks.

 

In the short term, the three-dimensional breeding model will not disappear, but as the policy level shifts and the breeding industry and environmental protection are linked, the government will strengthen the management and control of the pond breeding environment. Some areas have banned the construction of pig houses and duck sheds in ponds. In the long run, farmers still have to make timely changes to cope with changes in the general environment. Maybe you can see the fish feed extruder machine.

 

5. Large polyculture mode

 

Large-scale polyculture is the mixed culture of tilapia and common carp, dace, grass carp, bighead carp, silver carp, etc., making full use of water space and fish feeding habits, thereby improving the efficiency of the entire breeding process. The table below shows the seedlings and income of the large-scale polyculture model of tilapia farmers in Enping City, Guangdong Province, for your reference.

 

Compared with three-dimensional farming, the large-scale polyculture model of tilapia avoids drug residues and substrate pollution in livestock and poultry manure, has higher operability, and still has a large excavation space.
