CATDOLL : CATDOLL: What is the reasonable method for stocking fish in large waters?

1. What are the reasonable methods for stocking fish in large waters?

The method for the rational development of fish in large waters is mainly to classify the farmed fish first, so that there is no phenomenon of big fish eating small fish, and then feed them carefully.

2. What fish are suitable for raising in rice fields?

In rural areas, basically every household has its own rice fields. Some farmers also raise some aquatic products in them to make money. The most common is fish farming. In fact, you can raise several kinds of aquatic products. Here are six low-cost and high-efficiency aquatic projects recommended to you.

The following aquaculture products are low-cost and highly profitable in rice fields:

1. Fish farming in rice fields

Fish farming in rice fields is mainly based on rice, while fish farming is also considered. Not only can fish products be obtained, but fish can also be used to eat pests and weeds in rice fields. At the same time, the fish's excretion of manure and turning over of the soil promotes the decomposition of fertilizer, creating good conditions for rice growth, thereby achieving the goal of increased rice production and fish harvest. Generally, rice production can be increased by about 10%. The main farmed fish are grass carp and carp, and crucian carp, silver carp, bighead carp, and dace can also be farmed.

2. Farming shrimp in rice fields

Dig trenches around the rice fields and use the shallow water environment of the rice fields to grow rice and raise crayfish. Rice is planted and raised from late April to early May, and the seedlings are planted from the end of May to early June. Shallow water, wide rows, and dense planting methods are adopted, and the planting density on both sides of the trenches on the inner side of the ridge is appropriately increased to give play to the marginal advantages. The specification of crayfish stocking is 200-300 per kilogram, and the density is 3,000-4,000 per mu, and the time is from April to May.

3. Raising loaches in rice fields

Raising loaches in rice fields is a relatively simple breeding method, but it requires raising and reinforcing the ridges, and installing escape-proof facilities at the inlets and outlets. Dig a "well"-shaped ditch in the field, 30 to 40 cm wide and 50 cm deep, and release 1,000 to 2,000 loach fry per mu. Use livestock manure and compost as base fertilizer, and feed bean cake, vegetable cake, rice bran, etc. every day. Field management is the same as that of ordinary rice fields, and more than 50 kilograms of mature loaches can be produced per mu.

4. Raising crabs in rice fields

Crab farming in rice fields is a rice-crab symbiotic farming model. Rice planting adopts large ridges with double rows, edge row density, soil testing and fertilization, biological pest control and other technical methods, so that crab-raising rice fields have sufficient sunlight and fewer diseases, which not only ensures rice yield, but also produces high-quality rice. River crab farming adopts early temporary rearing, early feeding, and early field planting, which can not only remove weeds in rice fields and prevent rice pests, but also improve soil fertility through feces.

5. Raising frogs in rice fields

Frog farming in rice fields is a symbiotic breeding model of rice and frogs. It can not only control the harm of rice field pests and reduce the use of pesticides, but also maintain the natural state of frog survival, which is beneficial to the growth and development of frogs and saves breeding costs. At the same time, frog farming in rice fields has significantly increased income. The utilization rate of paddy fields where frogs are released is about 80%. Although the total rice output has decreased by about 20% due to the reduction in effective planting area, the economic benefits have greatly increased.

6. Raising eels in rice fields

The rice field eel breeding model is to slightly transform the rice field with good water retention performance as a breeding base. The transformation of the rice field mainly involves digging one or several small eel ditches in the rice field and setting escape prevention nets on the rice field ridges. There are many advantages to raising eels in rice fields. It does not affect the cultivation, management and harvest of rice. It can also use the good shallow water conditions and shade environment in the rice field to implement semi-artificial and semi-wild breeding of eels, thereby increasing the output rate of farmland.

3. What fish should not be kept in the fish tank when aquatic plants are placed?

Friends who keep fish all want to put some water plants in their fish tanks, so that the fish can swim among the water plants, which is a unique charm. However, what kind of fish should not be kept in water plant tanks? Today, the editor has sorted out some information, hoping to help everyone.

1. Large pencil fish: likes to nibble on the thin water plants in the aquarium.

2. Silver plate: mainly feeds on aquatic plants.

3. Red-bellied Firemouth: It is restless and highly destructive to aquatic plants.

4. Snake fish: They like to dig in the sandy bottom, which often prevents the roots of aquatic plants from taking root in the water.

5. Silver shark: It likes to feed on the tender shoots of aquatic plants.

6. Crown loach: commonly known as three-striped loach. It likes to dig in the sandy bottom and destroy the orderly arrangement of aquatic plants.

7. Red-tailed black shark: It acts in groups and likes to dig in the sand and destroy aquatic plants.

8. Golden Baby: A very beautiful pufferfish, it is very popular among aquarium enthusiasts. Golden Baby feeds on snails. However, since they also like to attack aquatic plants and often bite large holes in the leaves, they are not suitable for being kept in aquariums with aquatic plants.

9. Goldfish: Goldfish are not tropical fish and cannot adapt to water temperatures above 26 degrees. Goldfish like to nibble on tiny aquatic plants.

4. Is it more risky to raise Tibetan pigs or sheep?

I think the risk of free-range Tibetan pigs is definitely greater than that of free-range sheep. First of all, free-range means that the two are released into the mountains and forests to live and grow naturally. This is why the risk of pigs is higher than that of sheep.

5. What should be the reasonable fish stocking density?

The stocking density of fish is mainly related to the fish species and size. Generally, the number of conventional fish species stocked per acre is 600-1200. For larger or faster growing fish, the stocking density can be controlled to be smaller. For smaller and slower growing fish, the initial stocking density can be higher.

6. How to fish in waters with big waves?

1.

Choose a suitable fishing spot

When you encounter big waves in the river, don't rush to fish. First, observe the surrounding environment, pay more attention to the wind and waves, the direction of the water flow, and the speed of the water flow. Then observe whether the river flow is relatively gentle. When choosing a fishing spot, we can choose a place with slow water flow, so that when casting a rod to fish, the bait will not be washed away quickly. But when choosing a fishing spot, you should follow the principle of fishing big fish against the wind. After all, big waves are definitely caused by wind. But fishing big fish against the wind does not mean fishing directly against the wind, but choosing to fish with the wind at the leeward outlet.

2.

Choosing the right fishing tackle

When fishing in a river with big waves, the choice of fishing gear is also a science. First of all, the fishing rod should not be too long. After all, when fishing in the waves of a river, the closer you are to the shore, the smaller the waves are. In order to reduce the impact of the waves on fishing, and at the same time the fish will be closer to the shore, you can only choose a rod less than 5.4 meters.

As for the line combination, since big fish have a greater chance of coming to shore to feed when the wind and waves are strong, the chance of catching big fish will be much greater. The line combination can be slightly larger, and it is best to use a 3.0 main line with a 2.5 sub-line.

As for the choice of fish hooks, barbed fish hooks are the best option. After all, fishing in strong winds and waves requires preventing fish from escaping. Barbed fish hooks are more conducive to piercing fish and are not easy to come off, thus avoiding the phenomenon of fish escaping.

Due to the large waves, you can choose a long float or a jujube-shaped float that is wind and wave resistant, has good buoyancy, and has a long body and tail. When fishing in strong winds and waves, from my experience, a long float has greater advantages than a jujube-shaped float, and has better stability. You can choose a long float with a lead capacity of more than 4 grams.

3.

Choose the right bait

Because the waves in rivers are large and the currents are relatively strong, when fishing in rivers, the choice of bait and nesting materials must be very careful.

When making a nest, you need to combine the wind, waves and water flow to make the nest. Because of the relationship between wind, waves and water flow, sometimes the prepared nest will be washed away by the water not long after a while. Therefore, when fishing in rivers under such circumstances, try to choose solid nesting materials, such as plant bait, rice, corn and other crops, or use animal viscera in a cloth bag to make a sinking stone nest. However, it is best to use fishy smell to lure fish and keep fish in the wind and waves.

Bait. It is best to choose solid bait, such as corn, earthworms, red worms, etc. When fishing in rivers with big waves, the editor recommends using meat bait, because firstly, meat bait is resistant to blisters and does not need to be changed frequently, and secondly, its strong fishy smell can attract more omnivorous fish to eat, thereby increasing the fish catching rate.

4.

Grip

When fishing in waters with big waves, the main thing is to catch the top float, displacement and black float. In the wind and waves, there is still a certain pattern in the up and down movement of the float caused by the water ripples. You can judge according to the movement of the water ripples and filter out the false drift caused by the water ripples. When the pattern is broken and the floating phase of the float is abnormal, it may be a signal of catching fish. This requires calm observation and careful distinction. You can still distinguish the fish signal. When the signal of catching fish appears, you must catch it quickly.

7. What are the fish species in the Great Lakes?

The "Five Great Lakes" in this question should be the five Great Lakes of the United States. There are a large number of white-spotted pike and banded pike (North American pike) in the five Great Lakes of the United States. The adult banded pike can reach a length of more than 1.2 meters, even up to 1.8 meters, and weigh up to 150 kilograms. There are no less than 20 other fish species.

8. What are China’s six major water bodies?

1. Yangtze River:

The Yangtze River runs from west to east across central China, with hundreds of tributaries radiating from north to south, extending to parts of eight provinces and autonomous regions, including Guizhou, Gansu, Shaanxi, Henan, Guangxi, Guangdong, Zhejiang, and Fujian. The basin area is 1.8 million square kilometers, with a total length of more than 6,300 kilometers.

2. Yellow River:

The Yellow River, which originates from the Zhaqu River in the Chahasila Mountain of the Bayankala Mountains on the Qinghai-Tibet Plateau, the Karji River in the northern foothills, and the Yuguzonglie River in the west of the Xingxiu Lake, forms a "J" shape. The Yellow River flows through nine provinces and regions in China and finally flows into the Bohai Sea.

3. Heilongjiang:

Heilongjiang River is one of the largest rivers in Asia, flowing through Mongolia, China and Russia. It is located in northeastern Asia. In ancient China, it was called Yushui, Heishui, Yushui, Wangjian River and Shilihan River. Heilongjiang River has two sources, the southern source is Ergun River, and the total length is 4440 kilometers.

4. Pearl River:

The Pearl River, also known as the Yue River, is the second largest river in China and the third longest river in the country. The Pearl River originally referred to a 96-kilometer-long waterway from Guangzhou to the estuary, and was named after the famous Haizhu Island (Shi) it flows through. Later, it gradually became the general name for the Xijiang River, Dongjiang River, Beijiang River and various rivers in the Pearl River Delta.

5. Lancang River:

The Lancang River originates from the Guyongqu section of Zaaqu at the foot of Jifu Mountain in the northwest of Zaduo County, Yushu Tibetan Autonomous Prefecture, Qinghai Province. It originates from the foot of a mountain called "Jifu Mountain" in the north. The domestic length of the river is 2,139 kilometers.

6. Tarim River:

The Tarim River has a drainage area of ​​1.02 million square kilometers and a total length of 2,179 kilometers (some say 2,327 or 1,321 kilometers, but if the longest tributary, the Hotan River, is taken as the source, the total length is 2,376 kilometers). It is the longest inland river in China and the fifth largest inland river in the world.

9. How to choose a fishing spot in wild waters with large drop in height?

, choose fishing spots according to time changes

Generally speaking, it is better to fish near the water in the morning and evening, because it is quiet in the morning and evening, and there won't be much noise to scare away the fish. You can take advantage of the water's abundant aquatic plants, thick silt, rich impurities and organic matter, and more fish, and you can often catch large and diverse fish.

During the day, the surroundings are noisy and it is easy to scare away the fish near the shore, so you should cast the rod far away and fish in the middle of the water away from the shore. In addition, you should fish in the west in the morning and in the east in the afternoon. This is in line with the direction of sunlight. In the morning, the sun shines in the east, and anglers in the west can avoid projecting their shadows on the water surface and scaring away the fish, and keep the water surface calm. The opposite is true in the afternoon.

2. Fishing position according to water quality

First of all, we should choose waters without harmful substances, but the clearer the water, the better. Because the organic matter content is higher in ponds where people often wash vegetables, animal feces and feed, the fish here are not only numerous, but also large, thick and delicious. The saying "big fish are found near chicken coops and pig pens" is for this reason. In addition, the places where several water currents meet, especially the confluence of cold and warm currents in the ocean, are rich in nutrients and plankton, making it easy to catch fish.

3. Choose the fishing spot based on personal practice

The practical fishing position is the fishing position that anglers have summed up after many personal experiences. Some specific fishing positions cannot be obtained by theory, but are judged by the experience gained by anglers through many practices. The practical fishing position is often more real and reliable than the fishing position found by theoretical judgment. Therefore, experienced anglers are always willing to fish at their fixed fishing positions.

4. Fish that are too fat or too thin are not suitable for fishing

The richness of water quality is determined by the amount of plankton and nutrients in the water. If the water quality is too thin, it contains too few plankton and nutrients; fish are less active in it, so it is not suitable for fishing. However, more nutrients are not necessarily better. Overly rich water quality is mostly brown-green. Although fish have more food, there is a lack of oxygen; secondly, the water is turbid and visibility is low, which is also not suitable for fishing. From the perspective of water quality alone, the most suitable waters are those that are slightly rich (slightly brown) and are most suitable for fishing.

5. The fishing spot should be remote

Experienced professional anglers prefer to go fishing in the suburbs away from the downtown area. First, the air here is fresh, which is good for the health of the anglers themselves; second, the environment is elegant and there are many fish; third, there are few pedestrians passing by, which has little impact on the activities of the fish. When fishing, it is best not to have too many people watching, as there are too many people and it will disturb the anglers' peace of mind; in addition, human voices can easily disturb the fish in the water.

6. Tips for choosing fishing spots

To obtain information about the fishing spot, you can use methods such as "look", "smell", "ask", "listen" and "try". "Look" means to learn about the relevant situation by observing the color depth of the water area, water ripples, and the activities of fish schools in the water; "smell" means standing at the downwind side of the water and sniffing against the wind. Generally, the fishy smell is stronger in places with many fish; "ask" means to ask local anglers or the public whether there are fish or whether there are fish species that you are satisfied with; "listen" means to stand in a place with downwind and listen to the sounds of fish swimming, playing, and biting water plants; "try" means that the angler can personally test the depth of the water and even conduct trial fishing.

7. Choose the fishing spot according to the terrain

The terrain of the reservoir is complex, especially the interface area has a large drop, and there are many fish. The intersection of deep and shallow water and the ditch are rich in bait, and the fish are concentrated. The upper layer of the dam is also where fish gather to feed. In addition, steep slopes, village drainage channels, and docks are all good places for fishing. As for the best fishing spots in rivers, they should be at the inlet of small tributaries or the inlet of sewers, which is also where fish gather to feed, and often have a large harvest.

8. Choose the fishing spot according to the shape of the water area

In long waters, fish mostly swim along the long side, so you should fish along the middle of the long side, at the waist; in square waters, fish must pass through the four corners to swim back and forth, so you should fish at the corners; in addition, the parts of the shore that protrude into the water are conducive to artificial baiting and fish eating, which are ideal fishing spots; places where there are live water buckets, the water inlet has sufficient dissolved oxygen, and fish gather; some anglers also place oxygenators artificially by the water based on this principle to create larger splashes and sufficient oxygen to attract fish.

10. How deep are the waters where big carp usually live?

Wild carp generally like to live within 0.5-25 meters, but they seldom go to water depths between 10-25 meters because the pressure is too great. They only swim to such deep places to hibernate in winter. In other seasons, they will play and forage within 8 meters. The most suitable depth for them is the shore within 5 meters.

Artificially farmed carp usually live in water depths of 0.8-1.2m. The pond is usually 2.0m deep, with 10-15cm of silt at the bottom and 1.2m water depth, making injection and drainage convenient.
