Temperature rises at the end of spring and early summer, and fish farming management issues
October 08 07:02:01, 2024
Fish is a temperature-changing animal. Water temperature is low in winter and spring, and fish are in hibernation. Under normal circumstances, fish activity is small, food intake is also very small, fish body will gradually thin. After the spring, as the temperature rises, fish gradually start to feed. We should seize this favorable opportunity to fertilize pond water to allow fish to eat as early as possible, so that fish can resume growth as soon as possible. Early spring feeding of fish should catch an "early" word. Since the temperature is still relatively low at this time, the food intake of the fish is still relatively small. The interval feeding method is adopted. Generally, it is fed once every 2 to 3 days. It is better to feed at sunny noon to ensure that the fish are in 2 to 3 It is advisable to eat within hours. Feeds fed should be easily digestible commodity feeds. After the Ching Ming Festival, the water temperature gradually recovered, but the digestive power of fish is still not strong, and the amount of feeding can only gradually increase. During the period from the rain to the summer solstice, the food intake of fish began to increase, and the amount of feed to be fed should be appropriately increased, but it should not be too much. Feed feeding can be changed from interval feeding to daily feeding. The feed is best placed on a fixed food farm in order to reduce feed wastage and observe fish eating. While doing a good job in feeding management, we must pay attention to improving water quality. Some people say that the transparency of pool water should be controlled at 30 to 40 centimeters. This standard will not work in this season, and it will not reach the production requirements for water, fat and fish. Many years of practical experience in production tells us that the transparency of pool water should be maintained at 5 to 10 cm in the late spring and early summer. When fertilizing water quality, the specific method should be determined according to the season, water temperature, water color, transparency and other conditions. When fertilizing the water quality, traditional organic fertilizers can be used, as well as commercial drug fertilizer kings. In early spring, the temperature is low, organic matter is decomposed slowly, and fertility is kept for a long time. When fertilizing, the principle of less quantity should be mastered, so as to keep the pool water fat, live, tender and cool.
