CATDOLL : CATDOLL: How to raise golden carp

1. How to raise golden carp

There are two key points to keeping fish: one is feeding. Every morning after getting up, the first thing I do is to feed the fish. Fish also have conditioned reflexes. As long as they hear my footsteps, they all float to the surface of the water and keep making smacking sounds, knowing that the owner is here to serve breakfast. The fish food is bought from a fish store, 30 yuan per catty, it is an orange-red granule the size of corn, with a fishy smell. I sprinkled the fish food into the tank, and the fish rushed to grab the food, swallowing it, and it took less than half a minute for all of them to be eaten. Seeing that the fish are still swimming around on the surface and seem to be not full, don't be soft-hearted at this time, sorry, wait until tomorrow!

The second is water. It is not good to change the water in the fish tank frequently. Because the newly changed water is raw water, which is not conducive to the life of fish. When I bought the fish tank, I bought an aerator. This is a very magical thing. It has two major functions. In addition to continuously adding oxygen to the water, it also has a very important function, which is to absorb fish feces. Therefore, fish feces are never seen in the fish tank. They are all sucked into this black long strip. Every ten days or half a month, take out the aerator and take out the two sections with sponges. At this time, you will find that the black sponge has turned orange-red. This is fish feces. Put it in the pool and keep washing and squeezing it with tap water, and it will return to its original state. It takes less than 5 minutes. This kind of feces water is most suitable for growing flowers.

The water in the fish tank has a fishy smell and can be used to grow flowers. It is the best fertilizer water. When there is only 2/3 of the water in the fish tank, I use tap water to fill it up. Therefore, my family belongs to low-carbon fish and low-carbon flower farming. I also bought a double-sided magnetic brush, one in the water and one outside. It is firmly attracted by magnetism. When there is dirt on the inner wall of the tank, as the brush moves up and down, left and right, the dirt on the inner wall of the glass can be cleaned cleanly.

Raising fish at home is really effortless and worry-free. It not only brings vitality to the home, but also has an advantage. Due to the continuous evaporation of water, it can also regulate the air humidity in the home!

2. Offshore fish farming technology for golden drum

Golden drum fish is an omnivorous and bottom-feeding fish. It is mild-tempered and likes to live in groups. It can be mixed with large fish of the family Sophora japonica. The water temperature for breeding is 22-26 degrees Celsius. It likes weakly alkaline hard water. Some salt can be added to the aquarium. Golden drum fish likes to move in the middle and bottom layers of the water layer. Studies have found that it prefers to eat aquatic plants and live bait.

1. Golden Drum Fish Breeding Technology

Golden Drum Fish, commonly known as Golden Drum Fish, belongs to the order Perciformes, the suborder Perciformes, and the family Golden Drum Fish. Golden Drum Fish is a warm-water small- to medium-sized fish, distributed in the Indian Ocean, the Pacific Ocean, the South China Sea and the southern East China Sea of ​​my country, especially in the coastal areas of Guangdong. It inhabits near-shore reefs, mangroves and salty and seawater waters with dense seaweed. The body length is generally about 100 mm, and the larger ones can reach 280 mm. It takes 2 winters to grow into commercial fish. However, due to the special freshness of Golden Drum Fish, the diversity of market demand and human hobbies, Golden Drum Fish is still a high-priced seafood product that is in short supply, with a price of about 70 yuan per kilogram.

The golden coin fish is a euryhaline warm-water fish. Juvenile fish can live in groups in the surface waters near the estuary. The young and adult fish gradually migrate to the deeper and rocky waters far from the shore to live independently. It is a marine fish and often enters fresh water. It is slightly afraid of cold, and there is a risk of freezing to death if the water temperature is below 10℃.

The golden coin is an omnivorous fish that feeds mainly on animals. Juvenile fish feed on floating algae, copepods, and decapod larvae (water spiders); young and adult fish mainly prey on shrimps, crabs, benthic ringworms, and small shellfish. Under artificial breeding conditions, juvenile fish can be fed with Artemia nauplii and artificially caught or cultured copepods and cladocerans; juvenile fish over 2.5-3 cm can be fed with surimi and microcapsule pellet feed; adult fish mainly feed on surimi. Under domestication conditions, golden coin can prey in groups on artificially added surimi and soft pellet feed in a floating state or static state.

The pond area is about 2 mu, the pH value is 6.6-7.8, and the suitable salinity is 5-21‰. Seedlings are planted in June and July, with a size of 0.8-1.2cm. First, they are domesticated and induced to eat in the fixed net cages in the intensive culture pond, with a stocking density of 400-500 per square meter. After 30-40 days, they grow up to 1.5-2cm, and are transferred to the net enclosures in the transfer pond according to their specifications. The stocking density is 200-300 per square meter, and they continue to be cultivated for 60-80 days until they grow to 3-4cm. Finally, the net enclosures are removed, and the stocking density is controlled to 8-13 per square meter. The original pond continues to be cultivated until the end of spring and early summer of the following year, when they grow to 5-6cm, and then transferred to the cultivation pond for cultivation until winter and can be put on the market. During the breeding period, the pond is regularly filled with water to maintain the dissolved oxygen content in the water above 4mg/L, and the pond is prevented from flooding. During the winter, the water level of the pond is raised to more than 2.5m. The annual growth of the golden coin shows obvious stages. The main growth period is from May to November, and the small growth period is from December to April of the following year. The growth in the second year is basically the same as that in the first year. It can be seen that the growth of this fish is accelerated when the water temperature is high.

According to the characteristics of the independent bottom-dwelling life of the juvenile and adult goldfish, the winter-aged goldfish can be used as the main culture fish or as a supplementary culture fish for reasonable interculture and mixed culture with various estuarine and near-shore economic fish in the same pond. In mixed culture, it is necessary to consider the living habits and growth patterns of various fish to determine the corresponding stocking specifications, feed selection and feeding methods, and to plan the time of listing and fishing methods according to the netting rate, marketing season and market weight of various fish.

4. Breeding techniques of golden pineapple fish

Adult pineapples are relatively less susceptible to disease, but it is also important to pay attention to some issues when raising them, otherwise it is difficult to raise a good-looking pineapple. The first is water quality. The big pineapple has a strong adaptability to water quality, and it is not as demanding as parrots, but it is also necessary to pay attention to maintaining the water quality it likes in order to raise a fish with a bright yellow color. The big pineapple likes weakly acidic soft water. Like parrots, be careful not to use alkaline or hard water to raise pineapples, otherwise the color of the pineapple will turn white, not yellow. The second is water temperature. The water temperature required by the big pineapple is not as high as that of young fish. It can grow well from 22 to 30 degrees, but if you want the pineapple to grow faster, it is better to keep it above 26 degrees. The third is feed. The big pineapple is not as picky about feed as the small pineapple. It is willing to eat artificial granular feed, bloodworms, fish eggs, shrimps, mealworms, chicken and duck livers, etc., and often eats very full and can eat a lot, but the big pineapple loves mealworms the most and grows fastest when eating mealworms. The fourth is color. When the pineapple grows to 6 cm, you should start to pay attention to its color. Don't wait until it grows to more than ten centimeters before it starts to color. It will be too late. The color of pineapple is different from that of parrot. The color of parrot is red, while the color of pineapple is both red and yellow. The main feeds for coloring can be: fish eggs (yellow), river shrimp (red and bright), artificial coloring feed (such as Bao Zenghong). Pineapples that are fed with fish eggs for a long time are yellower than ordinary pineapples. River shrimp has a strong brightening effect on the red eye circles and red spots on the body of pineapples. If a pineapple that is more than ten centimeters long does not have red spots, as long as you insist on feeding river shrimp every day, within a month, the face and pelvic fins will become red and attractive. Fifth, mixed breeding: pineapples are docile large fish. Be careful not to mix them with some overly ferocious large fish (such as Luohan and Red Devil), otherwise the fins of the pineapple will be repeatedly torn and cannot be restored, greatly reducing the ornamental value. The above is my experience in raising pineapples. It is very superficial, and I would like to listen to your criticism and correction.
