Abstract

The invention provides a sipunculus nudus workshop culture pond which comprises a pond body. The pond body is a pit comprising a pond wall and a pond bottom, an opening is formed in the upper portion of the pond body, the pond wall and the pond bottom are built with cement or bricks, a filter composite layer is arranged on the upper surface of the pond bottom, a clay brick layer, a filter plate, a bolting-silk net and a sand layer are sequentially arranged on the filter composite layer from bottom to top, clay bricks of the clay brick layer are arranged at intervals, gaps are reserved among the clay bricks, a water inlet pipe is arranged on one side of the pond wall, a filter bag sleeves a pipe orifice of the water inlet pipe, and a drain hole is formed in the pond bottom. Aquaculture water in the pond body can be conveniently and rapidly replaced, poisonous and harmful substances in the sand layer are timely discharged, a substrate environment of a sipunculus nudus cement culture pond is effectively improved, harmful organism breeding is decreased, and siphon-worm survival rate and growth speed are increased. Besides, the culture pond is convenient to build, mount and debug and simple in operation and running maintenance, and has a great application prospect.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a culture pond for a naked star worm workshop. Background technique [0002] Naked star worms are commonly known as "sand worms" and belong to the phylum Astrozoa. This species is large, tender and delicious, and has always been one of the important sea treasures in South China, with high economic value. Affected by the rising market prices, fishing intensity is increasing day by day, coupled with changes in the marine environment and destruction of tidal flats, the resources of the naked star insects have decreased significantly. Therefore, in order to protect and sustainably utilize the resources of the naked starworm, it is necessary to change the traditional mode of overfishing natural resources and take the road of artificial breeding. In recent years, significant progress has been made in the research and application of artificial breeding technology of P...
