I have raised children at home for about 10 months, but I can't sell them after watching their professional artificial breeding for about a year!
In addition, tell you about the hairy crabs today:
In the summer of 2022, the persistent high temperature and drought caused heavy losses to the original world-famous Yangcheng Lake hairy crab producing area. So, there was one online earlier? No matter how hard you try, hairy crabs can't catch up with the Mid-Autumn Festival in 2022. A heated discussion.
The continuous high temperature, on the one hand, makes the water temperature in the culture area increase obviously and the dissolved oxygen decrease, which some hairy crabs can't resist? Bad environment? About one fifth of them died directly. On the other hand, under the influence of high water temperature, the number of algae, other plankton and crustaceans in the water body is greatly reduced, and crabs have lost important food sources. Even if they don't die, their growth rate becomes slower.
Take Yangcheng Lake hairy crabs as an example. Every August, they basically shed their shells for the last time, which indicates that hairy crabs are mature enough to catch and enter the market.
Affected by the high temperature in 2022, the last molting period of a large number of Yangcheng Lake hairy crabs was seriously delayed, and this road has not been completed yet? Process? . According to farmers, the last shelling period of Yangcheng Lake hairy crabs will be postponed until mid-September, 2022, so the time to market for hairy crabs is estimated to be postponed until around the National Day.
In order to improve the survival rate of hairy crabs, farmers have to take a series of measures, such as continuously planting plants such as water peanuts and duckweed on the water surface to cool the water body; Regularly adding oxygen to the water body to improve the dissolved oxygen content of the water body; In a crab pond with good conditions, farmers change water almost every day, and some even put ice cubes in the crab pond, and so on.
It is conceivable that after such operation, the cost of raising crabs by farmers will definitely increase greatly, and the price of Yangcheng Lake hairy crabs will definitely increase in 2022? A rising tide lifts all boats? .
