CATDOLL : CATDOLL: Is dace a marine fish or a freshwater fish? Can it be farmed?

1. Is dace a marine fish or a freshwater fish? Can it be farmed?

Mud carp is a freshwater fish, not a marine fish. They live in freshwater, not in seawater, and cannot adapt to seawater life. Mud carp itself has very high requirements for water temperature and mainly lives in tropical and subtropical areas. Therefore, they are mainly distributed in the south of my country, such as the Pearl River, Minjiang River and other waters. Mud carp often inhabits the bottom and middle layers of the Lancang River in the freshwater basin, especially during the winter. In addition, they also live in freshwater basins rich in organisms.

1. Is dace a marine fish or a freshwater fish? Dace is one of the fish that lives in my country. There are many species of fish, including marine fish and freshwater fish, and their living environment and body structure are quite different. Dace is a freshwater fish that lives in fresh water. They are not marine fish and cannot adapt to life in seawater. The main place of origin of dace is my country, and it can be found in many waters in my country. However, this fish has very high requirements for water temperature, so it is more widely distributed in tropical and subtropical waters. For example, it is widely distributed in the waters of Lancang River, Pearl River, Minjiang River and other waters in my country.

Dace often inhabits the bottom and middle of freshwater areas, and rarely goes to the upper layer. Especially in winter, the temperature is lower than usual, and dace have poor cold tolerance, so they will stay at the bottom of the water in winter and basically do not move. In addition, dace also has requirements for food. They will use phytoplankton and animals in the surrounding environment as their food, so they like to live in freshwater basins rich in organisms. For example, there are more dace in places with abundant aquatic plants.

2. Can dace be farmed? Dace is a unique fish species in my country and can also be farmed artificially. In fact, it is quite common to farm them artificially. As mentioned above, dace is a freshwater fish, so they also need to live in freshwater under artificial farming conditions. Since they have relatively high requirements for water temperature, not only wild dace mainly live in the south, but also farmed dace mostly live in the south. Moreover, since they are not very cold-resistant, some cold-proof measures need to be taken in winter.

3. Methods and techniques for fish farming in ponds, techniques for growing Thai ling flowers in fish ponds in summer

Pond cleaning and disinfection: dredge the pond irrigation and drainage channels and clean up the silt; disinfect with 200 catties of quicklime per mu, keep the water 2m deep, and release fish after cleaning it out for 1 week without any residual chemicals. Maintain water quality: Too much aquatic plants and algae in the pond will cause the water quality and air to deteriorate, so it needs to be cleaned regularly. Disease prevention: Sprinkle 20 catties of lime per mu every half a month during the high temperature period, and spray 250g of 90% crystal trichlorfon with water to prevent and control diseases.

1. Methods and techniques for fish farming in ponds

1. Pond cleaning and disinfection

(1) Clear the irrigation and drainage channels and clean the silt in the pond, leaving only 20 cm of silt.

(2) Use 200 catties of quicklime per mu of pond to disinfect and kill insect pests, pathogens and microorganisms, and keep the water 2m deep. After one week, clean the pond and make sure there is no residual pesticide. Then you can start breeding fish.

2. Maintain water quality

(1) When there are too many aquatic plants in a pond, the air quality of the pond will be poor. The decay of some substances will also affect the water quality of the pond. Some algae will emit harmful substances, pollute the water source, make the water acidic, and cause the water quality to age. Therefore, it is necessary to clean the aquatic plants or algae to maintain the water quality.

(2) A small amount of duckweed can provide shade, but too much will affect the reproduction of fish. Duckweed also grows quickly, so it needs to be cleaned up regularly.

3. Disease prevention

(1) Because fish are more susceptible to disease in the hot summer and the fluctuating temperatures in the autumn, during the high temperature period, sprinkle 20 kilograms of lime per mu every half a month and spray with 250 grams of 90% crystalline dichlorodiphenyltrichloroethane diluted with water.

(2) Fish feed needs to be disinfected with copper sulfate and feeding utensils should be cleaned with bleach. When gastrointestinal diseases are prevalent, feed can be fed together with garlic.

4. Pond environment

(1) A pond that is too large is difficult to manage. It is recommended that the pond be about 5 mu wide and 2 meters deep to facilitate drainage or water changes.

(2) Use slightly alkaline sandy soil, and the water quality should be such that it can be seen at a depth of 30 cm.

2. Techniques for growing Thai ling flowers in fish ponds in summer

1. Bait formula

(1) The taste of Thai ling

Thai carp likes sweet and slightly sour taste, so the prepared bait is sweet and sour.

(2) Formula 1

①First, boil 80% refined flour or corn flour in boiling water, then mix with 20% rapeseed cake (soybean flour can be used instead) and add a small amount of honey and sweet wine lees.

②Then put the bait into a container, cover it and seal it, and place it under sunlight for 2-3 days to allow it to ferment.

③ When using, add a small amount of rapeseed oil or sesame oil and mix it into a bait ball with moderate hardness and softness, so that the bait has a strong oily aroma and a slightly sour taste.

④Note: The flour used for fishing bait must be very sticky. If the flour is very sticky, the Tailing will not be able to eat up all the bait easily, leaving some bait left on the hook. The Tailing will then eat the remaining bait and the hook together.

(3) Formula 2

①First, prepare 40% corn flour, 20% refined flour, 10% peanut bran and 20% raw sweet potatoes (mashed).

②Then cook 5% cornmeal and 5% refined flour into a paste, put the other ingredients in a large bowl, then pour the cooked batter into the bowl while it is still hot and stir.

③ After the temperature drops below 50℃, add sweet wine lees (use 1 small bag of sweet wine lees for 1kg of raw materials) and seal it with a plastic bag.

④Then ferment the bait for 36 hours before use.

(4) Notes

① When fermenting bait, pay attention to the fermentation time. It should not be fermented for too long, because excessive fermentation will cause the bait to be too acidic, making it difficult for the Tailing to bite the hook.

② In late spring and early summer, Tailing has a strong appetite and likes to eat earthworms or river shrimps, especially live earthworms. Therefore, live earthworms can be used as bait when fishing.

2. Fishing gear selection

(1) 4.5-6.3m hand rod, 3-4 main line, 1.5-2 sub-line, 8-10 Ise-type hook or 9-12 Izu-type hook and 2-5 hard-tail vertical marker.

(2) When fishing for Tailing with a hand rod, it is usually better to use the platform fishing method.

3. Fishing skills

(1) Fishing time

Tailing has a weak appetite in hot and humid weather and at noon, but feeds frequently on rainy days and in the morning and evening. Therefore, it is better to go fishing on rainy days in summer and autumn, and fish in the morning or evening on normal days.

(2) Shallow and deep fishing

Tailing has a strong tendency to move towards temperature. It will go to shallow waters to find food on hot weather and at noon in summer and autumn, and enter deep waters on rainy days and in the morning and evening. Therefore, it is better to fish in shallow water on hot weather and at noon, and in deep water on rainy days and in the morning and evening.

(3) Bait

Tailing has a large appetite, and there are other fish competing for food, so the nest must be made large and sufficient, and the bait should be a combination of large pieces of peanut bran cakes and granular bait.

(4) Bait formula

①First, break the peanut bran cakes into palm-sized pieces. Add a few drops of liquor the night before fishing and seal them with a clean plastic bag. When fishing the next day, put 4-5 pieces as the main bait into each selected fishing spot. The auxiliary bait is fried peanut bran powder, soybean powder and wine lees. Mix them, soak them in water, pinch them into fist-sized pieces and throw them into the nest. Put in 3-4 balls each time.

② If there are no small fish biting the hook when fishing, you can use red earthworms as bait, and it is better to hang the hook with the whole living earthworm.

(5) Commercial bait

①Formula 1: 2 portions of King Grass Carp + 1 portion of Laogui 918 Crucian Carp Bait + 3g each of egg and milk + 4g of strawberry fragrance.

②Formula 2: 2 portions of king dace + 1 portion of sweet potato flour + 2 portions of peanut bran + 1/2 of silky powder + 4g of strawberry flavor.

(6) Characteristics of Thai ling biting hooks

① Tailing is more cautious when taking the hook, steadier than wheatling and not as ferocious.

③ After the Thai carp bites the hook, the float starts to move slowly and then gradually sinks into the water. Usually, you can catch the fish by lifting the rod during the black mark process.

(7) Notes

When small fish appear to be disturbing the hook, whether it is homemade bait or commercial bait, the fishy smell of the bait should be reduced to avoid the situation where other fish gather into the nest and the Tailing cannot get close.
