Sepia esculenta temporary rearing spawning device

Abstract

The invention provides a sepia esculenta temporary rearing spawning device which solves the technical problems that an existing sepia esculenta culture device is easy to damage spawning parents, is not applicable to habits of multi-time spawning of the sepia esculenta, and includes the spawning quantity of the sepia esculenta. The sepia esculenta temporary rearing spawning device is provided withbuoys, fine nylon ropes and sepia esculenta temporary rearing spawning bottles, wherein the two ends of each fine nylon rope are respectively connected with the corresponding buoy and a correspondingpottery pendant; the fine nylon ropes are connected with the sepia esculenta temporary rearing spawning bottles; each sepia esculenta temporary rearing spawning bottle is provided with a bottle cap, abottle body and a bottle bottom; openings at two ends of each bottle body are respectively and detachably connected with the bottle cap and the bottle bottom in a sealed way; first water passing holes are formed in the side wall of each bottle body; each bottle bottom is respectively provided with second water passing holes and a first accommodating groove; an attaching base is detachably connected with the groove bottom of the first accommodating groove in a matched way; the attaching base is provided with third water passing holes; a second accommodating groove communicating with the bottlebody is formed in the bottom surface of the attaching base; and a net sheet capable of being used for fertilized egg attachment is laid, connected and arranged at the groove bottom of the second accommodating groove. The sepia esculenta temporary rearing spawning device can be widely applied to the sepia esculenta aquatic product temporary rearing spawning culture.

Description

technical field [0001] The invention relates to a culture device, in particular to a golden squid temporary breeding and spawning device. 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 renewal, and rapid growth....

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
