How to raise herring
Herring is also called herring, and now herring has also been artificially propagated, so there are many species of herring. In our country, most of the herring is still produced in the Pacific region, so it is also called Pacific herring. Some time ago, canned herring became popular in the extreme challenge. Many people want to try whether it really smells that bad. Many Internet celebrities are also asked to eat canned herring. So today let's take a look at how herring is farmed.
1. Culture preparation
Because herring is a kind of marine fish, it can only be cultured near the ocean basin, so the herring culture industry mainly uses cage culture technology. We have to choose the appropriate sea area according to the living habits of herring, as well as the texture of the cage, and then put the cage to please the culture according to the specific conditions of herring, and spread it according to different depths. This is conducive to herring breeding in groups, and attention should be paid to the disinfection of cages, and finally, Jie Hu must do to install a red tide warning to prevent natural disasters.
2. Fish fry cultivation
The fry of herring is relatively fragile at the beginning, and it needs to be cultivated for a period of time before it can be put into the cage for large-scale rearing. First, we need to disinfect the place where the fry is cultured, and the second is to pour in the right amount of livestock feces. After three or four days, the fry is put into the culture pond. At this time, the fry mainly feed on soybeans, so we need to grind the soybeans into soybean milk or soybean meal. And add an appropriate amount of feed mixing to feed, except in winter, you need to feed at least four or five times a day, and once or twice a day in winter, and finally wait until the fry grows to seven or eight centimeters.
3. Fish fry restocking
The cage needs to be disinfected before the fry is released, and then the fry can be put in. The density of the fry in each cage needs to be reasonably planned according to the size of the fry and the area of the cage. In general, the maximum can not exceed 1500, but the minimum can not be less than a hundred, otherwise what to take to make money. In order to maintain the water quality and make full use of the culture space, we can also raise some silver carp in an appropriate amount.
4. Feeding and management
The feeding habits of herring are similar to those of tilapia, so the feed of herring is basically similar to that of tilapia, but the amount of feed is different. Secondly, it is necessary to feed an appropriate amount of crude protein feed, that is, foods such as coarse grains, up to three times a day, according to the size of herring, the change of weather and their food intake. At the same time, do not give bad or inferior feed to the herring, which will lead to the death of the herring.
5. Daily management
First of all, we should pay attention to the hygiene of the feed when putting in the feed, and the second is to clean up the food residue in the water in time after the herring is ingested, and then pay attention to the timing and positioning when raising, and that is to carry out reasonable fertilization according to the specific conditions of the water and cultivate plankton. At the same time, we should also pay attention to the irregular cleaning and disinfection of the cages, and finally, to prevent natural disasters, keep abreast of weather changes, and prepare for disasters.
