Autumn and winter management method of carp

In autumn, squid enters a semi-hibernation state. When the temperature drops below 15°C, they become inactive and rely on minimal breathing to survive the winter. To help them build up fat reserves for this period, it's important to feed them more high-fat foods such as mealworms, crickets, and fly larvae. This not only supports their energy needs during hibernation but also helps them stay healthy and strong. Proper harvesting is essential during this time. As the temperature decreases, squid tend to burrow into the mud. If you plan to harvest them before winter, first drain the pond water and carefully remove some of the mud from the bottom. Then, gently turn the mud to collect the squid. Avoid using sharp tools like shovels, as this can damage or injure the animals. Also, it's wise to keep a mix of large and small squid to ensure better egg production in the following year. Since eels are hermaphroditic, smaller individuals often have higher fertility and spawning rates. Keeping only large ones for breeding is not only inefficient but also unwise from a farming perspective. To protect the squid from predators and cold weather, once they start hibernating, the pond should be drained, but the soil should remain moist. Covering the area with a plastic net can prevent animals like cats and weasels from attacking them. In freezing conditions, proper insulation and antifreeze measures are crucial. For ponds with good water quality, consider using the deep-water overwintering method. Maintain a water depth of 50 to 70 centimeters and add aquatic plants or duckweed on the surface to help regulate the temperature and provide a stable environment for the squid to survive the winter safely.

Reagent Strips For Urinalysis

Urinalysis test strips refer to test strips that test for bilirubin, urobilinogen, ketone bodies, ascorbic acid, glucose, protein (albumin), blood cells, PH, etc. in urine.
Detection principle
1. pH: The pH value in the range of 5-9 is measured by the pH indicator, and the pH value of the fresh urine of a normal person is between 5-7.
2. Nitrite: The reaction is based on the reduction of nitrate to nitrite by Gram-positive bacteria in the urine. The nitrite reacts with p-aminobenzenesulfonic acid to form diazonium compounds, which are then combined with N-(1-naphthalene) )-3 aminopropanesulfonate combined with a pink color.
3. Glucose: According to the reaction principle of glucose oxidase, glucose oxidase specifically oxidizes glucose to generate glucuronic acid and hydrogen peroxide. Under the action of hydrogen peroxide, hydrogen peroxide oxidizes the indicator and turns color. .
Classification
Urinalysis test strips are divided into visual series and machine series. The visual inspection series is divided into several models according to different inspection items; the machine inspection series is divided into several models according to different applicable instruments.
1. Classification by measurement method
1) Visual inspection series
When observing the result, compare the color with the standard color code within the time specified on the color code, judge and read the result.
2) Machine test series.
For instrument operation, refer to the instruction manual of the Urine Analyzer used.
2. According to the number of measurement items
There are single-item, 2-item, 4-item and multiple test strips. Currently, 10-item or 11-item multiple test strips are most commonly used in hospitals.
3. Classification by structure
Urinalysis test strips with single-layer membrane structure and multi-layer membrane structure.
