Technical Field

The invention relates to a culture device, in particular to a temporary culture and spawning device for sepia esculenta.

Background

Sepia esculenta (Sepia esculenta) also called cuttlefish and cuttlefish belongs to cephalopoda, Sepiales, Sepiidae, and is a broad-temperature migration species. The sea cucumber grows eggs near islands which are favored to have water depth of 5-10 m, high salinity, slow clear water flow, hard substrate and more dense seaweeds, sand blasting and cave habits are generated during egg growing, and parents die after reproduction. The sepia esculenta is widely distributed in the far east sea of russia, the local state, the four countries and the nine states of japan, the west coast and the south coast of korea and the national waters of philippine archipelagia, and is mainly distributed in the middle and the north of the shandong langlan hill, the Qingdao, the yellow sea in China. It has short life cycle, fast generation updating and fast growth, is a good variety with higher economic value and is one of four oceanic fisheries in China.

Since the eighties of the last century, sepia esculenta is under the dual pressure of over-fishing and damage of habitat environment, the environment and production order of a spawning site and a proliferation protection area are threatened, and the resource regeneration capacity is remarkably reduced. The peripheral sea area of Shandong province is an important spawning ground of sepia esculenta, and is listed in local resource proliferation plan of Shandong province in 1992. At present, the sepia esculenta has two proliferation modes, one mode is that the traditional spawning base tamarisk or artemisia annua is used, although the price is low, the sepia esculenta cannot be recycled, and the quantity of the tamarisk and the artemisia annua is obviously reduced due to felling in successive years, so that the land vegetation is greatly damaged; the other adopts a semi-artificial proliferation protection mode, namely collecting the cuttlefish cages attached with the fertilized eggs of the sepia esculenta, and putting the cuttlefish cages into a certain sea area in a centralized manner to naturally hatch the cuttlefish cages for proliferation protection management. The sepia esculenta proliferation and release work is carried out on sunshine coastal areas in Shandong province by utilizing a semi-artificial proliferation protection method, and good economic benefits are obtained.

Although the effect is good when the cuttlefish cage is used as the spawning base, the cuttlefish cage is caught, so that spawning parents are easily damaged, the habit of multiple spawning of the sepiella esculenta is not adapted, and the spawning amount of the sepiella esculenta is influenced; and the cuttlefish cage is complex to manufacture and is not suitable for large-scale proliferation of the sepia esculenta.
