Detailed Description
The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1, 2, and 3: an ecological fish cage capable of releasing juvenile fish comprises a foam floating ring 1 located at the top, a steel ring is arranged in the foam floating ring 1, a plurality of ropes 2 distributed at equal intervals are connected to the foam floating ring 1, the tail ends of all the ropes 2 are connected with a hanging ring 3 together, an elastic steel wire 4 is connected below the foam floating ring 1, the bottom of the elastic steel wire 4 is connected with a middle steel ring 5, a bottom steel ring 6 is arranged below the middle steel ring 5, the middle steel ring 5 and the bottom steel ring 6 are connected through four elastic folding devices 19 uniformly distributed in the circumferential direction, an upper netting 7 covers the foam floating ring 1, the elastic steel wire 4 and the middle steel ring 5, a lower netting 8 is connected between the middle steel ring 5 and the bottom steel ring 6, a top netting 9 is arranged at the top of the upper netting 7, a plurality of lateral netting 10 are arranged on the lateral side, all the net openings are connected with extension parts 20 in the direction towards the inside of the upper net 7, the hanging ring 3 is also connected with a bait bag 11 through a rope, the bait bag 11 can enter the inside of the upper net 7 through the top net opening 9 when the fish cage is in a working state, the bottom steel ring 6 is also provided with a plurality of sinkers 12 which are evenly distributed in the circumferential direction,
