Farmers urgently seek good defense against the next wave of strong salty attacks
The last round of strong salty tides affected the normal life of the people to a certain extent. The use of river water in the cage aquaculture industry was in danger. It is reported that the salty degree of the cage culture base of the Modaomen Waterway on the Xijiang River has reached 14 miles. If it lasts for more than one week, it will cause great losses to farmers. According to the prediction of relevant departments, the salty tide of the next wave may be even more serious, and some farmers urgently seek a recipe for preventing salty tides.
Pearl River oysters are not afraid of salty
The city's oyster breeding is concentrated in Nanlang Town. The local farmed oysters have a long history. At present, the largest farmer is Xu Huajian. His oyster breeding base covers an area of ​​1,000 mu. The reporter learned from an interview yesterday that the salty tide in the last round has significantly increased the saltiness of the cultured water. Fortunately, the oysters were resistant to saltiness and escaped the looting.
Or influence cage fish culture
The coastline of the city is 26 kilometers long, the sea area is 176 square kilometers, shallow beach covers 160,000 acres, and the inland water area is more than 200,000 acres. In recent years, rapid development of river cage culture has mainly concentrated on the Modaomen waterway of the Xijiang River and Xiaolan Waterway.
Banfu Town, a large breeding farmer Chen Guirong, has more than 100 cages in the cage breeding base of the Modaomen Waterway in Xijiang. He told reporters that according to the usual tests, the saltiness of the breeding base is 2-4 ‰, which is suitable for fish growth, but during the last wave of salty tide, the highest saltiness reached 14 ‰. He said: "The test results startled me and I never saw such a high salinity. Observing that the fish's ability to move was obviously weakened. Fortunately, it lasted only three or four days. Once it lasted for more than 10 days, it could endanger the fish. Lifelike."
Chen Guirong said that the next wave of stronger salty tides will soon come. Once the salty tide threatens the survival of fish, I do not know what to do. I have no anti-salty experience and I must consult aquaculture experts to learn relevant knowledge.
Expert statement
According to experts in fisheries, salty levels below 2 ä¸ä¼š will not affect the freshwater aquaculture of the four major populations, but the salty effect can reduce the disease, but when the saltiness reaches 3-5 ,, the growth rate of freshwater fish will decrease. Slow, reaching 8 miles and for some time it is possible to salt the fish. For brackish seawater aquaculture, the salinity of normal fish growth is 2-4 ‰, and the fish growth rate is slow at 5-8 。.
