The invention relates to a penaeus japonicus ceramsite filter bed culture system which comprises a culture pond, a bottom layer support, a bolting-silk net and a ceramsite filter layer. The bottom-layer support is erected at the bottom of the culture pond, the bottom-layer support is used for supporting the ceramsite filter layer, the bottom-layer support forms the ceramsite filter layer, a culture area above the ceramsite filter layer and an overhead area below the ceramsite filter layer in the culture pond, and the bottom-layer support is a sieve-shaped porous sieve plate with supporting legs; the bolting-silk net is laid on a bottom-layer support in the culture pond, the periphery of the bolting-silk net is tightly attached to the pond wall of the culture pond, the edge of the bolting-silk net is higher than the ceramsite filter layer, and the bolting-silk net is used for filtering water and enclosing ceramsite; the ceramsite filter layer is laid on the bolting silk net, the ceramsite filter layer is composed of a plurality of ceramsite, the ceramsite is porous ceramsite formed by firing argil, and the ceramsite filter layer is used for providing a sand diving environment for penaeus japonicus and purifying water. The breeding system is simple in structure and convenient to operate, manpower is saved, and emission is reduced.
Description
technical field [0001] This application relates to the field of prawn farming, in particular to a ceramsite filter bed culture system for prawns in Japan. Background technique [0002] Japanese prawns (Penaeus japonicus), commonly known as: flower shrimp, bamboo-jointed shrimp, flowertail shrimp, spotted shrimp, car shrimp, belong to Crustacea, Decapod, Penaeidae, and Penaeus. The small shrimp body is called shrimp money. The body is light yellow, with a blue-brown horizontal stripe pattern, and the tail tip is bright blue. The carapace is thicker, the frontal angle is slightly bow-shaped, the upper edge has 8-10 teeth, and the lower edge has 1-2 teeth, the frontal horn side groove is very deep, extending to the back edge of the carapace, and the liver and stomach ridges are very obvious. The frontal ridge has a central groove. The first step has no seat spines, the male genus has a thick protrusion on the top of the middle leaf, and the female genus is cylindrical. Adult...
