Pellet feed feed fish four note
Pay attention to the water quality and dissolved oxygen in the fish pond and find that the water quality is bad. Add water in time to improve the water quality of the fish pond. The dissolved oxygen per litre of water in the fish pond is generally required to be more than 4 milligrams. If it is less than 4 milligrams, the fish pond should be oxygenated. Pay attention to adjust the amount of feeding should be based on changes in water temperature appropriate increase or decrease the amount of feeding, because the water temperature and the fish's intake, the water temperature is high, the fish eat more food instead of feeding less. Water temperature above 10 °C, feeding amount can account for 3% to 4% of the total weight of pool fish. Pay attention to choose different diameter pellet feed Different size fish should be fed different diameter pellet feed. Generally, fish with a body length of 4-6 cm should be fed a pellet feed with a diameter of 0.5 mm. For a fish with a length of 7-8 cm, a pellet feed with a diameter of 3 mm should be fed. Pay attention to vitamin supplements because vitamins have been destroyed during pellet production. Therefore, in the use of granular feed fish, should be fed a small amount of vitamin-rich green feed to supplement the lack of vitamins.
