It has a frame body structure, the entrance end of the seedling box is provided with a reinforcing frame, and the reinforcing frame is provided with elastic ropes, and the elastic ropes are staggered and form a mesh opening;

The phoenix anchovy seed collection device can collect fish fry in the water through the main hull and cooperate with the seedling assembly. In the process of picking fry, as the number of fry collected increases, the river water required for temporary storage of fry also increases, which leads to a continuous increase in the overall weight of the main hull. When the weight of the main hull increases To a certain extent, the auxiliary hull can provide buoyancy support to the main hull; the auxiliary hulls on both sides increase the stability of the center of gravity of the main hull on the water surface, and can reduce the risk of the main hull overturning when facing the wind and waves on the river; Through the flexible ropes provided on the first connecting rod and the second connecting rod, the water depth for picking seedlings of the hoisted seedling picking assembly can be adjusted.
