Description

technical field [0001] The invention relates to a method for industrialized artificial breeding of saddle grouper. Background technique [0002] Saddle band grouper is one of the largest species of grouper fish. It is known as the king of grouper. It grows extremely fast, has obvious weight gain effect, and is expensive. In the indoor cement pool, the physical and chemical factors of the growth environment are artificially regulated, so that the fry can grow quickly and healthily, and the survival rate of the seedlings is improved; this seedling raising technology is the first in the world. Contents of the invention [0003] The object of the present invention is to provide a method for factory artificial breeding of saddle grouper. [0004] Industrialization artificial seedling raising method of the present invention is as follows: [0005] 1. Environmental conditions for seedling cultivation [0006] a. Cement cultivation pool [0007] Area 15~35m 2 The rectangular ...
