Culture techniques of silverfish (noodle fish)

Silverfish is a kind of translucent fish, which can be cultured in the salt water of the freshwater river. the meat is delicious and is very popular with people. So, today the editor will take you to learn about the culture technology of silverfish!

1. Pond requirements

The first thing to cultivate silverfish is to build a pond suitable for the growth of silverfish. You can choose ponds that have been farmed before to ensure clean water, leeward, sufficient light, good drainage and irrigation capacity, and control the area and number of ponds according to the number of cultures. the depth of the pond shall not be less than 2 meters. There should be certain aquatic plants in and around the pond. Silverfish are very fragile, so we cannot mix with carnivorous and omnivorous fish to prevent these fish from attacking and eating silverfish. Disinfect and clean the pond three days before stocking.

2. Seedling cultivation

First of all, it is necessary to prepare the seedling cultivation pond, turn over the mud at the bottom of the breeding pond, and then thoroughly disinfect the silverfish and put in the right amount of clean water, because the growth ability of the silverfish seedlings is relatively strong, and the ordinary pond water cannot be cultivated, so it is necessary to use fertilizer and water to cultivate the young fish. The young fish feed on rotifers and all kinds of nauplius, start eating about 9 days after hatching, and put in bait in time after eating. If you do not eat for more than three days, it will lead to death, so it is necessary to apply enough fertilizer before the young fish begin to eat, to ensure that the young fish have enough bait after eating, to apply fertilizer regularly during the breeding period, and to control the amount of fertilizer according to water color and water volume. Ensure that the transparency of the pond water is more than 35 cm.

3. Adult fish culture

The growth ability of adult fish is strong, and the growth rate will be obviously accelerated, so it is necessary to fertilize and cultivate plankton frequently, fertilizers can be used with rotten farm fermentative fertilizer, the dosage can be controlled, and the dosage should be properly adjusted according to the water quality and the quantity of culture. then in the process of culture, it is necessary to prevent floating head, because the requirement of dissolved oxygen for silverfish growth is very high, if the silverfish floating head is not treated in time, it may lead to large area death. When the floating head phenomenon is serious, it is necessary to reduce the amount of fertilizer, avoid too much plankton, change water regularly, and add oxygen-increasing equipment to increase oxygen in time.

4. Feeding and management

The eating habits of silverfish will change at a certain stage, gradually changing from vegetarian feed such as cladocephalus to carnivorous fodder. We should observe the growth of silverfish regularly. When it is found that there are a small amount of fish and shrimp in the intestines and stomach when the body length of most silverfish is close to 0.8-1 cm, it shows that the silverfish is already in a period of diet transformation. At this time, we should add appropriate amount of small fish and shrimps smaller than silverfish. To promote the growth of silverfish, we should pay attention to the number of fish and shrimp to prevent overdensity. Introduce an appropriate amount of pregnant green shrimp in May-June, and the hatched young shrimp can be eaten by silverfish.

The above is the silverfish culture technology that Xiaobian arranged for you. I hope I can help you!
