Diligent pond, anti-floating head Check the pond 2 or 3 times a day. Look for fish floating heads before and after dawn. Observe the fish’s feeding situation in the afternoon and check the fish’s all-day eating conditions at sunset to see if there are signs of floating heads. When the weather changes abruptly, it is also advisable to inspect the pond around midnight to prevent serious floating heads. The hot weather, high water temperature, water quality fertilizer, sudden drop in food intake, fish swimming in the water layer without sinking, and early morning deaths of small shrimps in the pond all indicate that the dissolved oxygen in the pool will decrease, and the water quality will deteriorate. Floating head phenomenon occurs, especially when the weather is hot and rainy, the floating head phenomenon is likely to happen before midnight. To prevent floating head method: When there are signs of floating head, feed and fertilizer should be stopped immediately, water should be injected immediately, dissolved oxygen should be increased, and water quality should be adjusted. If the fish pond is far away from the water source, 100 kg of yellow mud may be used per acre of water, and 5 kg of salt or 2.5 kg of raw gypsum powder may be added. Inject water and promote growth To cultivate a pond fish, we must first raise a pool of water. The majority of intensive fisheries with high yields are over-fertilized and need to be controlled in the following ways: Note for the convenience of the new fish ponds can be 5 to 7 days for a change of water, each time you can not change the water too much too much injection, injection and pond water temperature difference between the wells, streams should be the case. A microbiological agent is applied every 10 to 15 days, and sunny days are applied at shallow water in the sunny area. The aerator is opened slightly earlier in the morning when it is calmer. Note Fish ponds with poor new water conditions can be treated with algaecides and other drugs. They should be sprayed on a small area in the afternoon of the pond in sunny afternoons to control some algae and must not splash in the whole pool. Diligent decontamination, disease prevention Frequently fish out fish left over to eat the remaining grass, residue, remove the stems of non-perishable grass roots, often move the grass frame, clean the food table, sprinkle lime to the grass rack and food table parts, regular drug prevention, pay attention to dispel the birds and beasts, etc. Predators.
L-Ascorbic Acid, also known as Vitamin C, is a six-carbon lactone produced by plants and some animal species but not by humans and other primates. Ascorbic acid functions as an enzymatic cofactor for multiple enzymes, serving as an electron donor for monooxygenases and dioxygenases.
