Early summer fish culture management
Fish is a temperature-changing animal. The climate in winter and spring is cold, the water temperature is low, and the 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. The majority of farmers should seize this favorable opportunity to fertilize pond water to allow fish to eat as early as possible to prompt the fish to 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. Therefore, the interval feeding method should be adopted during the breeding process. Generally, feeding is conducted once every 2 days to 3 days. It is better to feed at sunny noon to ensure It is advisable for fish to finish within 2 hours to 3 hours. Feeds should be fed with good quality, 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 cm to 40 cm. This standard is not acceptable in this season, and it cannot reach the production requirements of water, fat and fish. Many years of practical experience in production tells us that the transparency of pool water should be kept between 5 cm and 10 cm in the late spring and early summer. In the cultivation of fertilized water, 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.
