The invention relates to the technical field of urechis unicinctus breeding, in particular to a seedling raising device for urechis unicinctus breeding, which comprises a urechis unicinctus seedling raising box body, breeding assemblies are arranged on two sides of the urechis unicinctus seedling raising box body, each breeding assembly comprises a device port, and the device ports are arranged on one side of the urechis unicinctus seedling raising box body. According to the invention, through the arrangement of the interlayer type culture assembly formed by sequentially stacking the outer side water-permeable net plate, the liftable blocking plate and the inner side water-permeable net plate, when water body exchange needs to be adjusted, the control assembly drives the blocking plate to stably lift in a guide space formed by the two layers of fixed net plates; the design ensures that water flow needs to be subjected to double filtering and buffering under any opening degree, linear fine regulation and control of flow can be achieved, effective escape prevention of at least one physical barrier can be maintained all the time, and therefore the technical defects that when a traditional seedling raising window single-layer structure is opened, the escape risk is high, and water flow impacts and directly disturbs seedlings are fundamentally overcome.
