CATDOLL : CATDOLL: How to cultivate bigmouth catfish? What is the appropriate breeding density?

1. The breeding technology of bigmouth catfish and the appropriate breeding density

1. Environmental requirements: Build a pond in a place with sufficient running water source, and the pond must have good water retention. 2. Stocking preparation: Drain water 2 weeks before stocking, then clean the entire pond with quicklime solution, soak for 1 week and then clean the pond. 3. Stocking: Stock fry of the same size, not too large or too small. 4. Feeding: After stocking, you can feed feed after a few hours. 5. Stocking density: 8-10cm size, 1000-1500 per mu.

1. Breeding technology of bigmouth catfish

1. Environmental requirements

To breed catfish, you must have a clean water source. You must build a pond in a place with sufficient running water. The pond must have good water retention and must not be permeable. You can plant some water plants in the pond to provide a habitat for catfish, but the water plants cannot grow on a large scale to prevent them from blocking the water surface, blocking oxygen, and causing poor breathing. The inlet and outlet can be covered with mesh to prevent other animals from entering and prevent fish from escaping. The pond should be raised and reinforced.

2. Preparation for stocking

Two weeks before stocking, you can use quicklime solution to clean the pond after draining the water. After soaking for one week, wash the pond again. Then fill it with clean water and soak it until two days before stocking. After draining the water, it must be refilled with water to prepare for stocking. Before stocking, the fry must be soaked in light salt water or other disinfectant solution for 20 minutes. They must be sterilized before stocking, and the feed for feeding in the water must also be prepared.

3. Delivery

Generally, 20,000 fry can be placed in a pond of one mu, or less. When placing fry, be sure to choose fry of the same size, not too large or too small, otherwise it is easy to grow unevenly and kill each other. The time of placing can be chosen at noon when the temperature is suitable.

4. Feeding

A few hours after the release, you can start feeding. The feed can be made of some grains into powder, and then kneaded into a ball with water to avoid loosening too quickly when entering the water and causing waste. You can also feed it some shell meat and snail meat, but it must be chopped. You can also feed it small fish and shrimp, mix it with grain powder and nutrient powder and feed it twice a day.

5. Maintenance

You can add fertilizers to the water and cultivate natural bait for the fish. You must pay attention to changing the water at ordinary times. The water source must be flowing all the time. You must prevent the fish from escaping on rainy days. When the temperature is high, you must pay attention to oxygenation to maintain oxygen in the water. A common disease of largemouth catfish is printing disease. When the disease is found, it must be treated in time, and the whole pond must be isolated and disinfected. At the same time, bleaching powder is used for disinfection. Common insect pests of largemouth catfish include wheelworms. For prevention and control, copper sulfate and ferrous sulfate can be used together.

2. What is the appropriate breeding density of largemouth catfish?

1. In order to improve the survival rate and breeding efficiency, the largemouth catfish species must be above 8cm and of uniform size. The stocking density is generally 1000-1500 per mu for 8cm-10cm and 800-1200 per mu for 10cm-12cm. 100-120 large-sized silver carp and bighead carp species of 150-250g can also be added to the pond to regulate water quality.

2. When breeding bigmouth catfish, please note that the new pond should be disinfected with chlorine dioxide, copper sulfate, potassium permanganate, etc. or exposed to the sun. Fish can be put in after 1 week. Bigmouth catfish are suitable for survival in water temperatures of 20°C-28°C. The water quality should be fresh and pollution-free, with sufficient dissolved oxygen content. At the same time, the water quality should be fully regulated frequently. Do not accumulate old water, which is not conducive to the healthy growth of fish. Generally, 1/3 of the old water can be replaced every 3-7 days, and oxygenation equipment can be added when conditions permit.

3. You must insist on feeding compound feed as the main method of breeding, because compound feed has balanced nutrition, is easy to digest and absorb by fish, has strong attractant and good palatability, can increase the growth rate of bigmouth catfish and shorten the breeding cycle. In order to meet the nutritional needs of breeding at different times, do not choose mechanical feeding when feeding. Feeding too much will easily cause leftover feed, resulting in the remaining feed sinking to the bottom and polluting the water quality. Feeding too little will cause the fish to be not full and their physical fitness will decline, which is not conducive to the healthy growth of fish. Therefore, feed the feed in a timely, appropriate and reasonable manner.

Second, if the crocodile is over 20cm and the water temperature is relatively high, its growth rate will be very fast???

As long as the temperature and food are sufficient, they will grow very fast no matter where they are.

3. Is catfish an amphibian?

Catfish, Animalia-Chordata-Chordata-Actilopsis-Siluriformes-Siluridae-Silurus-Silurus. There are 4 whiskers on the mouth, the upper ones are long and the lower ones are short. They are carnivorous, mostly wild, and have low requirements for water quality. They can be cultivated artificially. They grow fast, and some species can grow to be very large.

It is a completely aquatic animal, not an amphibian.

4. What does it mean to read fish?

It should be catfish.

Catfish, the same as catfish. There are many species, the most common ones are catfish (native catfish), bigmouth catfish, bearded catfish (tang mullet), leather bearded catfish (Egyptian bearded catfish), Hakka commonly known as Tang slippery fish

Catfish, Animalia-Chordata-Chordata-Actilopsis-Siluriformes-Siluridae-Silurus-Silurus. There are 4 whiskers on the mouth, the upper ones are long and the lower ones are short. They are carnivorous, mostly wild, and have low requirements for water quality. They can be cultivated artificially. They grow fast, and some species can grow to be very large.

Bigmouth catfish, Animalia-Chordata-Chordata-Actinopterygii-Siluriformes-Siluridae-Silurus-Bigmouth catfish. It looks similar to catfish, also with 4 barbels, but with a very large mouth and much larger individuals than catfish. It can be artificially bred and grows fast. The fry bred in the same year can grow to 500-750 grams in the same year, 1500-2000 grams in the second year, and 3000-4000 grams in the third year. Most of the catfish sold in the market are of this type, with ordinary meat and cheap price.

Catfish, local catfish, also known as pond mullet, pond angler fish. Animal kingdom - Chordata - Chordata - Actinopterygii - Siluriformes - Catfish - Catfish - Catfish. 8 whiskers, 4 on the upper and 4 on the lower. Yellow body color, wild fish grow slowly, generally weighing no more than 1 catty, high nutritional value, good taste. Can be artificially cultivated, great market potential.

The leather-bearded catfish, also known as the Egyptian bearded catfish and the Egyptian pond catfish, was introduced from Egypt. Animalia - Phylum Chordata - Subphylum Chordata - Class Actinopterygii - Order Siluriformes - Family Catfish - Genus Catfish - Species Leather-bearded catfish. It has 8 whiskers, is black all over, and is huge. It is mostly artificially bred, grows very fast, can weigh up to 2 kg after one year of breeding, and the largest individual can reach more than 10 kg. It has very low requirements for water quality for survival and is resistant to low oxygen. The meat quality is not very good, and the market price is cheap. However, it is easy to breed and grows fast, so many people also breed it.
