Description

Technical Field

[0001] The invention relates to a breeding device, in particular to a golden squid temporary breeding and spawning device. Background Art

[0002] Golden squid (Sepia esculenta), also known as cuttlefish and mullet, belongs to the class Cephalopoda, order Sepiidae, and is a wide-temperature migratory species. It likes to lay eggs near islands with a depth of 5 to 10 meters, high salinity, clear water and slow current, hard bottom, and dense algae and reefs. It has the habit of spraying sand and living in caves during spawning, and the parents die one after another after reproduction. Golden squid is widely distributed in the Russian Far East Sea, Honshu, Shikoku, Kyushu of Japan, the west coast and south coast of North Korea, and the waters of the Philippine Islands. In my country, it is mainly distributed in Lanshantou, Rizhao, Shandong, Qingdao, and the central and northern Yellow Sea. It has a short life cycle, fast generation renewal, and rapid growth. It is an excellent variety with high economic value and was once one of the four major marine fisheries in my country.

[0003] Since the 1980s, golden squid has been facing the dual pressures of overfishing and habitat destruction. The environment and production order of its spawning grounds and proliferation protection areas have also been threatened, and the resource regeneration capacity has declined significantly. The sea areas around Shandong Province are important spawning grounds for golden squid, which were included in the Shandong Provincial Local Resource Proliferation Plan in 1992. At present, there are two ways to proliferate golden squid. One is to use traditional spawning bases such as Tamarix or Artemisia annua. Although they are cheap, they cannot be reused. In addition, due to continuous logging, the number of Tamarix and Artemisia annua has decreased significantly, causing great damage to terrestrial vegetation. The other is to adopt a semi-artificial proliferation and protection method, that is, to collect squid cages with golden squid fertilized eggs attached, and concentrate them in a certain sea area to allow them to hatch naturally for proliferation and protection management. The semi-artificial proliferation and protection method was used to carry out golden squid proliferation and release work in the coastal area of ​​Rizhao, Shandong Province, and achieved good economic benefits.

[0004] Although the effect of using squid cages as spawning base is good, the squid cages themselves are for the purpose of fishing, which can easily damage the spawning parents and are not suitable for the habit of golden squid to lay eggs multiple times, which affects the egg-laying amount of golden squid.
