CATDOLL : CATDOLL: What fish can be raised in blue potion aquaculture?

1. What fish species are farmed in Blue Potion Aquaculture?

Mini parrot fish. Blue water medicine is the common name for methylene blue. In order to prevent the occurrence of saprolegniasis, care should be taken to avoid damaging the fish body and parasite bites during operation, and a small amount of salt can be added to the water to inhibit the occurrence of saprolegniasis.

When the fish is found to be infected with Saprolegniasis, you can use: 1. Soak in 1-2ppm methylene blue solution for 20-30 minutes, or soak in 5ppm furazolidone solution, or directly sprinkle 0.02ppm malachite green solution or 0.3ppm formaldehyde solution into the aquarium to inhibit the growth of mold. You can also increase the water temperature to inhibit the growth of Saprolegnia. Install a 15-watt ultraviolet lamp on the top of the aquarium and irradiate it for several hours every day to effectively inhibit or eliminate the growth of Saprolegnia. 2. Soak in 3% salt water once a day for 5-10 minutes each time. 3. Soak in 2ppm potassium permanganate solution plus 1% salt for 20-30 minutes, or soak in 1-2ppm malachite green solution for 20-30 minutes.

2. How to raise fish and what kind of aquatic products are the most profitable?

Let’s not talk about how to raise fish. First of all, you need to know what kind of aquatic products are suitable for your area. The cost of raising fish itself is not very high. At present, it is mainly contracting fish ponds or breeding in water tanks. If you care about making money, then you have to analyze your local market needs and the relationship between supply and demand. It is also very simple. You can get information from various restaurants and fishmongers in the vegetable market. Then discuss what kind of fish you said can make money. In fact, you can make money by raising anything. What the breeding industry cares about is the breeding cost. As long as you have a market, it is normal to produce fish in more than 20 days using current products such as fish feed. So if you want to make money by raising fish, you have to go to the market yourself to analyze the gaps and understand the market conditions. At present, raising fish is really not as profitable as raising shrimp.

3. What should we do if fish get enteritis in aquaculture?

Prevention and treatment of fish enteritis:

(1) Do not feed spoiled feed. Feeding with green feed can help prevent enteritis.

(2) Regulate intestinal health. Adding Yucca schidigera extract to feed can inhibit the accumulation of ammonia nitrogen and nitrite, while improving the balance of beneficial intestinal flora, enhancing resistance and preventing the outbreak of enteritis.

(3) Maintain sufficient dissolved oxygen in the water, adjust the pH value of the water, and control the water temperature.

(4) When fish enteritis breaks out, it is important to adjust the water and improve the bottom first to prevent the disease from further deteriorating. When the condition is relatively mild, use amoxicillin + doxycycline hydrochloride for treatment. When the condition is relatively serious, use florfenicol + doxycycline hydrochloride for treatment.

In short, although fish are easy to raise, if diseases are not properly prevented and controlled, great losses will be caused. We should adhere to the principle of prevention is better than cure. Long-term use of Yucca extract can effectively prevent the incidence of enteritis, improve water quality, regulate the intestines, enhance physical fitness, and ensure high yield and high income of tilapia farming!

4. What can be used to purify water for aquaculture fish?

Physical, chemical and biological methods can be used.

5. Which fish are special aquatic products?

Special aquatic fish should refer to farmed species other than conventional species (common fish and shrimp) that are farmed on a large scale, such as sea cucumbers, sea horses, sea urchins, jellyfish, economically farmed fish (rainbow trout, loach, catfish, mandarin fish, sturgeon, freshwater silver pomfret, tilapia, black snakehead, etc.), river crabs, frogs, and turtles, which are special farmed animals with relatively high economic value and relatively small farming scale.

6. What varieties of aquatic fish are there?

Aquatic fish include abalone, grass carp, crucian carp, carp, silver carp, etc.

7. What are some similar words to fish farming?

There are: farming, clearing land, planting flowers, transporting, breeding, sweeping the floor, brushing teeth, washing face, watering flowers, raising fish, cooking, feeding pigs, repairing, building houses, sharpening knives, taking walks, chopping wood, picking vegetables, singing, fighting, eating, dancing, getting a haircut, taking a bath, combing hair, washing face, buying vegetables, mopping the floor, knocking on the door, beating drums, playing the piano, drawing, weeding, cleaning, planting trees, playing, drinking, watching the moon, writing, lecturing, tug-of-war, giving speeches, walking, skipping ropes, etc. These are all similar words to farming.

8. Fish farming technology?

1.

Stocking time selection: Fish should be released on sunny days when the temperature is not too low. Generally, the temperature should be between 2℃ and 5℃. At this stage, the fish scales are tight and the activity is small. It is not easy to injure the fish during fishing, transportation and stocking operations, which can reduce the morbidity and mortality of fish. It is easy to frostbite the fish on rainy days with low temperature or snowy, frozen and windy weather; when the temperature is too high, the fish scales are loose and the activity is large, which is easy to injure the fish during operation.

2.

Stocking of fish: Before stocking the fish, check whether the drugs have lost their effectiveness after pond cleaning. In early spring, the water temperature is low and the toxicity disappears slowly. Water should be taken in advance and test fish should be released. According to the stocking plan, individual size, density, and matching species and specifications, the fish that can be released at one time should not be released in batches, so that the fish can adapt to the environment, start eating early, and promote growth. At the same time, [Gold Iodine] should be used for drug disinfection when stocking fish.

3.

Feeding at the right time When the water temperature rises to 810℃, fish begin to eat, and the amount of food intake gradually increases with the increase of water temperature, so they should be fed in time. Feed once a day or every other day, and choose to feed at noon on a sunny day; as the water temperature continues to rise, the number of feedings can be increased to twice, that is, feeding once in the morning and once in the afternoon. Feeding should adhere to the principle of four determinations (timing, quality, positioning, and quantity), and the specific daily feeding amount should be flexibly controlled according to the weather, water temperature, and the feeding situation of fish. For grass carp weighing more than 1 jin, it is recommended to feed Da Beinong high-grade expanded feed 8103 in the early stage of feeding; for small grass carp mode, it is recommended to feed Da Beinong microecological juvenile fish special feed [Intestinal Liver Health], and the feeding rate is controlled at about 0.5%1%. This product is rich in nutrients and probiotics, which can quickly repair the fish intestines, restore the physique, and improve immunity.

9. Are there any good methods for aquaculture (various fish) in hotels?

It is not clear that if you keep it in a fish tank, do not use tap water. If you use tap water, you must expose it to the sun for 2 days and add 0.01% edible salt to the water. In addition, change 30% of the water every 3 days, so you can safely keep freshwater fish. As for saltwater fish, I don't know much about it so I won't comment.

10. How to issue an invoice for live aquatic fish?

Live aquatic fish are agricultural products and are duty-free products with a zero tax rate.
