Title
Control Sudden Shrimp Death
Details

On September 21, the shrimp died at Mollahhat, Fakirhat and Chitlmari upazilas of Bagerhat district due to changing weather at dawn. The subject of farmers' statements at the field level and inspection of shrimp farms on the ground and examining the soil and water of the farm shows that due to excessive temperature during the day and sudden rain at night, the quality of the water (pH and O2) changes and the shrimp die. Examination of the enclosure water shows that the pH of water in the morning at 10.30 o'clock is very low and indicates an oxygen crisis. Moreover, the black soil under the shrimp enclosure has a more pronounced shape of the crisis. In the meantime, it is important for farmers to be aware of the crisis facing climate change in the future. It is important for every shrimp farmer, especially the Galda shrimp farmers, to preserve one dose medicine per Ger. Because there is usually an oxygen crisis in the morning and the shrimp die before dawn, there is nothing to do with the farmer. Therefore, in order to address this crisis, zeolite national medications like Maxillite-P, Geopond Fresh,Ultramax, Topziolite, JV Zeolite, etc at a dose 100-200gm per Decimal . and Gasonex plus Y / Gasoline should be stored at the rate of 5 gram per decimal. In the morning or at any time if there is oxygen crisis, these two medicines should be mixed together and sprinkled. if the oxygen crisis is severe, then it should be sprinkled with 5-7 oxygen tablets per decimal . After that, a permanent solution should be taken by examining the water and soil of the enclosure. Free soil and water tests are provided at the Senior Upazila Fisheries Officer's Office, Mollahhat, Bagerhat. Shrimp cannot be made unsafe by using any unauthorized medication
