Electric mosquito repellent incense can be used to raise fish. The main component of mosquito repellent incense is pyrethrin, which is not harmful to fish, but harmful to arthropods. Therefore, you can't light mosquito repellent incense when raising shrimp and crab. Generally, if you raise fish in summer, you should first pay attention to controlling the water temperature and not let the temperature be too high. At the same time, make sure that the temperature difference is not too large, so as not to stimulate the fish. Feeding food must be quantitative, do not feed too much, and change water regularly. 1、 Can you light mosquito repellent incense for fish farming? You can light mosquito repellent incense for fish farming. Although the smoke of mosquito repellent incense will dissolve in water, its main component is pyrethrin, which will be harmful to arthropods, such as shrimp and crab, but has little impact on fish. However, the concentration of mosquito repellent incense should not be too high. At the same time, it is best to maintain a certain ventilation. It is better if there is a cover on the top of the fish tank. 2、 What should we pay attention to in summer? 1. The water temperature should not be high: in summer, we should first pay attention to the water temperature. If the water temperature is too high, it is easy to affect the health of fish. Moreover, high temperature will accelerate the reproduction of some bacteria. Sufficient light may also make the water eutrophic, resulting in algae explosion in the fish tank. Therefore, we must pay attention to cooling.
2. The temperature difference shall not be large: in summer, the temperature during the day is high, and the temperature at night will drop. A large temperature difference is unfavorable to the growth of fish, and even stimulate the fish body, affect its appetite, and may lead to its death. Therefore, in addition to cooling during the day, pay attention at night not to let the water temperature drop too low.
3. Feeding should be quantitative: when the temperature rises, the activities of the fish will be more vigorous. At this time, the appetite will also increase. Compared with peacetime, when feeding the same amount of feed, the fish will still grab food, but don't continue feeding at this time, otherwise too much feeding will lead to the death of the fish and the residual bait will pollute the water quality.
4. Timely water change: compared with other times, the temperature in summer is higher and the rate of water body deterioration is also increasing, so it is necessary to change water in time. The water change time is generally in the afternoon or evening, and about one quarter or one third can be changed each time. （YangYuNengDianWenXiangMa，XiaTianYangYuYaoZhuYiShenMe）
