With the continuous expansion of the scale of mud aquaculture, the water quality of the culture has been continuously deteriorating and the number of diseases has increased. The “flatulence” disease that has emerged in recent years is one of them. If not treated, it will often lead to a large number of deaths.

1 The symptoms of muddy "flatulence". Loach in the pond is expressed as the abdomen floating on the surface of the water, and sinking to the bottom of the water, to salvage it up to find mud bulging belly, the performance of the symptoms of swelling, and sometimes swelling in the abdomen, the abdominal wall is thin, the intestinal wall changes It's very thin. Sometimes accompanied by enteritis; most liver and gallbladder disease. Some liver and spleen are swollen and the liver is yellow, white, and green. Bile turns black and yellow. Severe illness occurred.

2 Causes of mudflat “flatulence”. 1 Muddy Intestinal Respiratory: In addition to using fleas and skin to breathe, the loach can also be used to breathe in the intestines. The muddy intestine not only has the function of digesting food, but also assumes the respiratory function. According to research, loach "intestinal respiration" can account for 1/3 of its respiratory capacity. When feeding, the number of "intestine breaths" increased. This number of Pegasus. Sometimes related to the quality of feeding. For example, after feeding a high protein or a single bait, the loach clusters in the pool and the number of "intestines" rapidly increases. After that, the bait is not baited. It swims in the pool and finally floats to the surface. Anatomical observations. The symptoms are as described above.

2The effect of water temperature on the loach: The suitable water temperature for loach growth is 14~28°C, the optimum water temperature is 23~26°C, when the water temperature is 5°C, the loach enters deeper waters and hibernates: when the water temperature reaches 30°C, it enters the state of hibernation, ie, enters the mud and stability. Do not eat it.

3 Loach food habit: Loach is an omnivorous fish. Loach has high digestive rate and conversion rate for animal foods, but it has low digestion rate and conversion rate for plant foods. In the case of artificial breeding, generally select the full-price compound feed with a protein content of about 30% to meet the growth and development needs of loach.

3 control methods. Quanchiposa salt, 5 kg/mu: Oral baits: 100 kg of feed added Xiaoshi Liwei scattered 500 grams, 500 grams Gantai music, 200 grams of allicin, 300 grams of salt, even fed 5 to 7 days.

Carbon Monoxide Detector

new high-performance sensors can effectively detect smouldering fires It can detect all kinds of indoor smoke. When the indoor smoke volume reaches the alarm concentration, the detector will alarm, the red indicator light will be on, and the buzzer will beep, so as to prompt the user to timely check the causes of the leakage accident and eliminate potential safety hazards.
