Abstract

Disclosed are a combined mandarin fish fries cultivating net cage and a using method. The combined mandarin fish fries cultivating net cage is characterized in that the net cag is rectangular, two net walls are added in the middle of the net cage to divide the net cag into three net cells, a first cell is made of 40-mesh bolting-silk net and is 2m*1m*1.2m in dimension, the net wall between the first cell and a second cell is a movable net wall convenient to demount, the second cell is made of a mesh with 0.3cm screen and is 4m in length and 2m in width, the combined cage of the first cell and the second cell is 5m in length and 2m in width, the net wall between the second cell and a third cell is a movable net wall convenient to demount, the third cell made of a mesh with 0.6cm screen and is 5m in length and 2m in width, and in this way, the combined net cage is 10m in length and 2m in width. With the combined mandarin fish fries cultivating net cage, frequent fishing of mandarin fish fries and changing of net cages are not needed during cultivation of the mandarin fish fries, damages to the mandarin fish fries are reduced, cultivation survival rate of the mandarin fish fries is improved, and labor intensity during cultivation of the mandarin fish fries is reduced.
