In extremely cold weather, Qingdao has a large area of sea ice. How does this affect the local aquaculture industry?

Affected by the cold wave this year, there has been a significant cooling in various places, which makes people bluntly say that this winter is very difficult. When it is cold, it will cause ice, and then in extremely cold weather, large-scale sea ice appears in Qingdao, which has brought great impact to the local aquaculture industry. Even the sea water can freeze, so you can imagine how cold it is. So what is the impact of such a large range of sea ice on aquaculture? Bian Xiao will take you to analyze: first, seafood is difficult to catch; Hypoxia may lead to a large number of fish deaths; Third, it is impossible to feed, and the fish grow slowly.

First of all, it is difficult to catch seafood.

It is said that relying on mountains to eat mountains and relying on the sea to eat the sea, the seawater on which local residents depend for survival is frozen, and it is difficult for many farmers to catch seafood. Once the sea water freezes, it is very thick. If you want to break it, you need professional tools, and it is still dangerous. But if it's not bad, it can't be caught on a large scale. Near the end of the year is the time when the market demand is greatest. Many farmers rely on these days to make money. This sudden cold wave caused them heavy losses, but the temperature will gradually rise and they can fish again.

Second, lack of oxygen

When the sea surface freezes, the outside oxygen can't enter the sea water, and all the fish will surface. Failure to break the ice in time will lead to large-scale death of fish. Some farmers will install some aerators, which is really environmentally friendly, but it is of little use. An aerator with insufficient power will only be a drop in the bucket for such a large-scale fish. Break the ice in time to minimize the loss as much as possible.

Third, it becomes difficult to feed.

Normal farmers are driving boats to feed the feed, so as to spread it evenly. But when there is a large area of ice, this method can't be used, because there is no way to break all the ice, so it can only be fed on the side. Without feed, seafood will grow slowly and can't be sold at the best time in the market, and it is difficult to make a direct ratio between income and expenditure.
