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.

The present invention discloses a vessel for three-dimensional breeding and raising of schizontids, belonging to the technical field of breeding vessel equipment. The vessel comprises a hull, with a breeding mechanism provided in the middle of the hull. The breeding mechanism comprises multiple cage assemblies and two lifting components. The cage assemblies comprise a box body and four tethering components. The box body comprises an upper cover and a baffle. Multiple first mesh holes are provided on the sides of the box body, and second mesh holes are provided on the bottom of the box body. The baffle is slidably embedded in the bottom of the box body. The tethering components comprise two tethers, a first lifting ring, and a first locking buckle. The two tethers are arranged vertically and fixedly connected to the upper and lower sides of the box body, respectively. The first lifting ring is fixedly mounted at the bottom end of the bottom tether, and the first locking buckle is fixedly mounted at the top end of the upper tether. The present invention effectively solves the problems of laying, replacing, and removing sediment and other substrates at the bottom of the breeding area, which are labor-intensive and labor-intensive, and the breeding area is relatively fixed, resulting in low water utilization and the inability of schizontids to fully absorb nutrients from the water.
