[Selected Cases] Successful Treatment of Dinoflagellate Outbreak in Sea Cucurbita Pond

Case Details

Time: May 3, 2020

Location: Breeding Area, Xinhu Town, Hekou District, Dongying City, Shandong Province

Breed varieties: sea cucumber

Farming area: 80 mu divided into 2 ponds with a water depth of 1.2 meters.

Water quality index: pool 1 PH:8.6 ammonia nitrogen: 0 nitrite: 0.003

2 PH: 8.7 ammonia nitrogen: 0 nitrite: 0

Description of the situation: Farmers reported that the water in both ponds was red, and there was a large amount of oil film. Sea cucumbers were also hard. Water samples were taken from the downwind. Microscopic examination found a large amount of dinoflagellate and dinoflagellate. One pond was more serious, while the other pond only had red water from the downwind.

Treatment Scheme

The next day, after a massive change of water in the serious pond,Bishui Jiedu Ann(5L) 20 mu per barrel, splash the whole pool,Weedley.30 acres per box, finallyLactic acid bacteria stock solutionEach bottle of 2 mu of land is splashed outside, and lactic acid bacteria are used to expand and accompany, splash at any time, control ph value, and gradually press down dinoflagellate.

Another pond to useWater Change OverlordEach pack is 2 mu, splashed in the limelight, and thenBishui Jiedu AnnDetoxification, supplement lactic acid bacteria.

Effect feedback

After 2 days of treatment, the water color changed obviously, the hardening of sea cucumber gradually disappeared, and the dinoflagellate decreased significantly after taking off the wind-head water microscope.

Case analysis

April to May every year is the peak period of dinoflagellate outbreak, especially this year. With unstable temperature and serious water pollution in the outer sea, dinoflagellate is especially easy to break out in alkaline water. With the release of dinoflagellate toxin, sea cucumbers will show stiffness, poor stretching, and vomiting of intestines after eating dinoflagellate by mistake.

Prevention recommendations: regular useWeedley.Regularly change the bottom, remove black mud and deodorize, prevent eutrophication at the bottom, inhibit dinoflagellates, cooperateBishui Jiedu Ann, can detoxify algae, restore sea cucumber physique, and use Zhongren importedlactic acid bacteria species, self-expansion, sprinkle once every 7-10 days to reduce ph and inhibit dinoflagellate outbreak. If some water bodies have been found to be red at the downwind, use them in time.Water Change OverlordSprinkle it near the downwind head, and then use the clear water to detoxify.
