Embodiment 1

[0070] From June 5, 2018 to July 20, 2018, the above-mentioned method was adopted in a special aquaculture base in Ganzhou City, Jiangxi Province to cultivate the seedlings of the big spiny loach.

[0071]1. Cultivation pool construction: (1) Brick rectangular cement pool with a length of 5m, a width of 4m, and a height of 1m. Smooth tiles; (3) special water inlet and drainage pipes are installed in the cultivation pond, and the water inlet pipe is a PVC pipe with a diameter of 40mm, which is installed on the top of the pond embankment at the higher end of the bottom of the cultivation pond. The water outlet is on the lower side of the pool bottom. First build a sewage collection tank with a length of 50cm and a width of 30cm. Cover the sewage collection tank with a plastic or stainless steel plate with holes. The water pipes are made of PVC pipes, which are connected to the outside of the pool, and then a 90° elbow is installed. The other end of the elbow is connected to a PV...

Embodiment 2

[0093] From June 12, 2019 to July 27, 2019, a special aquaculture base in Ganzhou City, Jiangxi Province was used to cultivate the seedlings of the large spiny loach. The method was the same as in Example 1.

[0094] The number of cultivation ponds is 1, and the area is 20 square meters. The structure and built-in special facilities of the cultivation ponds are the same as those in Example 1.

[0095] The fry stocking density and other management measures are the same as in Example 1.

Abstract

The invention provides a mastacembelus armatus fry cultivation device and a mastacembelus armatus fry cultivation method, and belongs to the technical field of fish farming. The cultivation device includes a cultivation pool (1), a dirt collecting pool (2), a cultivation net cage (3), a bait table (4), a moth-killing lamp (5), a sunshade stand (6) and an oxygenation device (7). Through the arrangement of the cultivation net cage in the cultivation pool, fries can be put in the net cage to cultivate, so that convenient management can be achieved, the growth of the fries can be promoted, and compared with traditional methods that directly cultivate the fries in the cultivation pool, manpower costs and time can be saved; during the pool separation of the fries, the methods adopting artificialnets to catch the fries are not needed; and the probability that the fries get hurt due to the pulling of the nets can be reduced by directly screening the fries in the net cage, so that the survivalrate of the fries can be enhanced. In addition, through the adopting of a method of the gradual transition of rotifer-tubificidae-compound feed in proportion, the problems of the conversion of feeding habits of mastacembelus armatus fries can be better solved, and bait utilization rates and fry survival rates can be enhanced.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to a cultivating device and a method for cultivating large spinach seedlings. Background technique [0002] Mastacembelus armatus is a species of ray-finned fishes, Perciformes, Mastacembelus armatus, and the genus Mastacembelus.
