Matters needing attention in platypus fish culture

Duck-billed fish is called American spoon Sturgeon, it is a large freshwater economic fish culture project, but also a very rare fish species. Platypus fish has no scales, few fish bones are transparent and edible, so it is also a favorite of chefs. Now all the platypus fish on the market are farmed, so the editor below will teach you a few things that you need to pay attention to in the process of cultivating platypus fish. Let's see if you really know the platypus fish.

1. Pond cleaning management

Duckbill fish are generally cultured in ponds or cages. For cage culture, we only need to select areas with good water quality and disinfect and clean the cages. In order to adopt pond culture, it is necessary to select fish ponds suitable for duckbill fish culture, then disinfect them with quicklime, add fertilizer to replenish water fertility after disinfection, and finally inject new water before breeding. If the fish ponds are improperly located or cleaned up improperly, the survival rate of fish fry will be affected.

2. Fish fry selection

Fish fry selection is in fact the same as other fish fry, to choose uniform size, robust, good mental state, no diseases and insect pests, no mechanical damage, easy to swim, eat good fry. Before stocking, the fish fry should be disinfected, and then a small amount of water from the fish pond should be taken for trial culture, and only if there is no problem can the fish fry be put into culture.

3. Water quality management

Platypus fish have strong adaptability to the environment, but the requirements for water quality are also very strict, especially the phenomenon of hypoxia must not occur in the water, otherwise it is easy to cause large-scale death. In general, the depth of the pond should be about 1.5 to two meters, and the second is that we should be equipped with an aerator to replenish the oxygen in the pool in time. In addition, the water is generally changed every 10 to 15 days or so, and the miscellaneous fish and weeds in the pond should be eliminated. Of course, some aquatic plants can also be properly cultivated to regulate the water quality and enhance the oxygen content in the water.

4. Culture method

Platypus fish can be divided into monoculture and mixed culture, for novice culture, monoculture is recommended, so it is not easy to cause problems. If we are mixed friends, then we need to pay attention to the proportion of mixed culture and control the number of farming. In general, we are cultured with silver carp and herbivorous fish, and the ratio is controlled at 1: 1: 8. At the same time, it is also necessary to control the number of aquatic plants to avoid eutrophication, leading to the failure of aquaculture.

5. Feeding and management

First of all, we should pay attention to the density of breeding. Monoculture usually puts about 40 to 100 tails per mu, while mixed farming usually puts about 20 to 70 tails. The second is to pay attention to the temperature of the water body, and according to the water temperature, weather, water quality and other conditions, reasonable control of feed supply. Normally, we need to feed three times a day, at 07:30 in the morning, 11:30 in the afternoon and 06:30 in the afternoon. There is to ensure that the nutrition of the feed balance, do not often change the feed.

At present, platypus fish are cultured in many areas, but the platypus fish on the market are still very rare, one of the biggest problems is that the mortality rate of platypus fish culture is very high. For farmers, the annual loss is also very large, so we need to solve this problem from the culture technology to improve the production of platypus fish.
