CATDOLL : CATDOLL: How are oysters farmed?

1. How to farm oysters?

Oysters, also known as oysters, are a kind of marine shellfish with wide temperature and salinity. They are mainly caught in the ocean, and are rarely cultivated artificially. The oyster seedlings used for artificial cultivation are generally natural seedlings in the ocean. The main cultivation methods include: raft culture, longline culture, trellis culture, etc. 5 to 6 months before the oysters are harvested, the cement columns in the cultivation area are moved to the muddy beach with fertile water quality and fast flow rate for fattening.

Due to the different types of oysters and the different sea environments, the seedling collection seasons are also different; therefore, artificial breeding is mostly semi-finished product breeding. That is, wild seedlings are used and then artificially cultivated. The growth environment is basically the same as that of wild shellfish.

Oysters, also known as oysters, are one of the larger species. There are many breeding methods, among which there are 8 basic methods (with key points): 1. Raft culture, which is divided into two types: hanging rope and cage culture. It is necessary to ensure that the water depth is about 4 meters, and choose a river mouth with low salinity to breed near the river. 2. Sowing and raising seedlings on the tidal flats; the site should be selected with small waves, flat tides, and pollution-free inner bays. Sowing is more suitable from mid-March to mid-April. 3. Oyster and shrimp mixed culture. With silt or mud sand as the bottom material, the water depth is more than 1.3 meters, and the daily average water exchange rate should reach more than 50%. The sowing time is selected in early April. 4. Stone throwing culture. The rocks of the oyster seedling machine are used as cultivation equipment, and the baby's baby, plum blossom and row cultivation methods are adopted. 5. Bamboo cultivation. Arrange in a straight or oblique manner with gaps in the middle to make the water flow smooth. 6. Bridge culture. The stone bars used in the bridge seedling method are rearranged, with 6 to 7 bars in a group, the distance between groups is about 50 to 60 cm, and the distance between rows is 1 to 2m. 7. Vertical stone culture. This method is relatively simple. As long as the amount of seedlings collected is appropriate, it can be allowed to grow naturally. It is mainly used for the cultivation of pleated oysters. 8. Grid farming. The water depth is 2 to 4 meters, and a fixed grid is set in a calm place. Most oyster seedlings are raised on a grid with shells and cement tiles. Each string is 1 to 1.5 meters long and the distance between strings is 0.5 to 1 meter. Note that the density should not be too high to prevent the bottom from being seen, so as to avoid being attacked by the natural enemies of benthic organisms.

2. What medicine and what ratio of seawater and fresh water should be used to make oysters fatter?

What medicine can Li Wang use to make the ratio of seawater to freshwater? It should be six to one to five.

3. How to make oysters fatter faster

Add some fertilizer to the water that is beneficial to the growth of oysters

4. How do I raise oysters? Others raise fish, but I want to raise some oysters for viewing and tasting. I live in a city far from the sea. How can I turn fresh water into

It's very troublesome. Do you know how much a filtration system for a saltwater aquarium costs? It costs tens of thousands of yuan. You also need to mix seawater salt with the water, and test and observe the salinity every day. Not to mention the trouble, the cost investment is very high. It is recommended to raise some freshwater shellfish.
