Especially in the developed areas of aquaculture, this service is more obvious. Therefore, many people don't buy quick test kits in their own fishing grounds, thinking that they won't use and don't understand them when they buy them, and they have to spend their own time. It is better to send them to the pharmacy directly if there is any situation. However, what I want to tell you today is that the quick test kit is one of the necessary weapons in fishing grounds, which is beneficial and harmless.
A gold boss in Meishan just came into contact with fish farming this year. He thought loach was easy to raise, so he bought more than four million loach splashes and went back to see for himself. Due to the immature culture technology, the transparency of the pond has always been high. After the weather warms up, the moss at the bottom of the pond grows in large quantities. After consulting the boss who sells seedlings, the medicine was spilled, and the dead moss foam has been floating on the surface of the pond for several days. During the day, some loach seedlings can be seen spinning and floating on the surface of the water, and some of them died when they saw it, with their mouths open.
According to his judgment, he felt that it was caused by lack of oxygen, because he took the pond water to the fishing pharmacy for testing before planting, which was normal, so in this case, he only sprinkled some oxygen-increasing particles at the bottom, and according to him, the effect was obvious after using it. When I went to his small fish pond this time, I took out the quick test kit and measured the relevant water quality of the pond. I didn't know it. In the test results, the contents of nitrate and nitrite almost reached the maximum limit of the test kit, and the dissolved oxygen was not high. Other indicators were still relatively normal, so I told him that the fish in the pond were mainly poisoned, not killed by lack of oxygen. Recently, it happened that transplanting water was being released, so I quickly suggested that he change the water, replace two-thirds of the water in the pond, and then change the bottom (because there are bubbles running to the water surface at the bottom of his pond, and the bottom material is very bad), detoxify and transfer water.
This is a counter-example, and there are many positive examples of using quick test kits, all of which show that the time to engage in aquaculture by experience has passed, and we need some methods and means to avoid detours and reduce losses. The rapid detection kit was originally produced to make aquatic products detection easier and convenient for farmers. It is called a rapid detection kit, which has three advantages.
First, the steps are simple, the results can be produced in a short time, and the illness will not be delayed;
Second, the application group is wide, and the combination of numbers, words and pictures can make different types of farmers understand and learn to operate;
3. The price is low and the effect is obvious.
Many places have sales of quick test kits. Just like fishing medicines, you should also pay attention to the following points when buying them:
1, look for businesses, and choose qualified and trustworthy manufacturers to buy;
2, don't be greedy for cheap, although the overall unit price of the quick test kit will not be very expensive, but the prices of different manufacturers or different sales points are still obviously different, so don't just try to be cheap, not worth the candle;
3. Operate according to the instructions (avoid strong light, etc.), and pay attention to the preservation conditions after use;
4. Don't use those that are about to expire or have expired, and don't be reluctant to give up, resulting in inaccurate test results;
5. Don't use the leaked ones. If the leaked ones are found at the time of purchase or before the next use after use, replace them with new ones for testing to avoid inaccurate test results.
