Embodiment 3
[0030] Example 3 : Cultivation and feeding experiment of mandarin fish seedlings
[0031] The breeding and feeding experiment of mandarin fish seedlings was carried out in a mandarin fish breeding center in Hubei. The purpose of the test at this stage is to cultivate the mandarin fish fry (about 0.6 cm in body length) that started feeding to the mandarin fish fry with a body length of about 1.4 cm. The test was carried out in 5 square (2mX2m) cement pools in the temperature-controlled first-level seedling cultivation workshop. The depth of the pool is 1.0 m, and the water depth is 0.8 m. Each cement pool is equipped with nano-aeration pipes and independent inlet and outlet pipes. Water temperature 23~25℃. Dissolved oxygen is above 5 mg / L. The pool numbers are 1, 2, 3, 4, 5, and the breeding density is 4000 tails / square meter. Among them, pool 1 is used as a control group, and the conventional mandarin fish compound feed is used to feed; pool 2-3 is the test group, and th...
