Sepia esculenta trapping and spawning device

Abstract

The invention provides a sepia esculenta trapping and spawning device. The sepia esculenta trapping and spawning device solves the technical problems that an existing sepia esculenta catching device is prone to damaging spawning parents, not suitable for the habit of repeated spawning of sepia esculenta and capable of affecting the spawning amount of the sepia esculenta. The sepia esculenta trapping and spawning device is provided with a buoy, a thin nylon rope, a pottery pendant, a support, and a sepia esculenta trapping and spawning bag, wherein the top end of the thin nylon rope is connected with the float; the bottom end of the thin nylon rope is connected with the pottery pendant; the sepia esculenta trapping and spawning bag is of a mesh-bag-shaped structure with one open end and oneclosed end, wherein the sepia esculenta trapping and spawning bag is provided with a funnel body and a barrel body which are communicated with each other; the funnel body is arranged at the opening of one end of the sepia esculenta trapping and spawning bag; a hollow spawning channel is formed in the barrel body; meshes for sepia esculenta to lay eggs are connected in the spawning channel; the support is provided with an annular support and a connecting support; the annular support is connected with the edge of an outer opening of the funnel body; one end of the connecting support is connected with the annular support; and the other end of the connecting support is connected with the thin nylon rope. The sepia esculenta trapping and spawning device can be widely applied to sepia esculentaaquatic product trapping and spawning devices.

Description

technical field [0001] The invention relates to a device for trapping and laying eggs, in particular to a device for trapping and laying eggs for golden squid. Background technique [0002] Golden squid (Sepia esculenta), also known as cuttlefish and mullet, belongs to Cephalopoda, Sepia order, Sepiaidae, and is a wide-temperate migratory species. It likes to lay eggs near islands with a water depth of 5-10 meters, high salinity, clear water, slow flow, hard bottom, and dense algae reefs. They have sandblasting and burrowing habits during spawning, and their parents die one after another after reproduction. Golden squid is widely distributed in the Russian Far East Sea, Honshu, Shikoku, and Kyushu in Japan, the west coast, south coast of North Korea, and the waters of the Philippine Islands. In my country, it is mainly distributed in Lanshantou, Qingdao, and the central and northern parts of the Yellow Sea in Rizhao, Shandong. It has a short life cycle, fast generation rene...

AI Technical Summary

Problems solved by technology

[0004] Although the effect of using squid cages as a spawning base is good, the squid cage itself is for fishing purposes, which is easy to damage the spawning broodstock, and is not suitable for the habit of golden squid spawning multiple times, which affects the spawning amount of golden squid; and the squid cage is complicated to make. , not suitable for large-scale proliferation of golden squid
