TECHNICAL FIELD

[0001] The present application relates to the field of aquaculture technology, and particularly relates to a device for attaching eggs of Sepiella maindroni de Rochebrune using a biological proportioning liquid of gorgonian. BACKGROUND

[0002] Sepiella maindroni de Rochebrune is an annual medium-sized squid, commonly known as cuttlefish, which grows fast and has delicious meat, and is a popular seafood food. Sepiella maindroni de Rochebrune is distributed in the northwest Pacific Ocean and the coast of the North Indian Ocean. The main fishing grounds in China are in the coastal waters of Zhejiang and Fujian. The highest annual yield exceeds 80,000 tons, and it is an important economic species in the world. In particular, the waters near Zhoushan in Zhejiang are the main producing area of Sepiella maindroni de Rochebrune.

[0003] Currently, the spawning of Sepiella maindroni de Rochebrune is mainly improved and stabilized by means of artificial squid reefs. Sepiella maindroni de Rochebrune prefers to attach eggs on substrates with a diameter of less than 7 mm. In natural waters, Sepiella maindroni de Rochebrune prefers to attach eggs on gorgonian. However, gorgonian grows slowly and cannot provide long-term and stable egg attachment protection for Sepiella maindroni de Rochebrune. SUMMARY

[0004] The purpose of the present application is to solve the problem that Sepiella maindroni de Rochebrune prefers to attach eggs on gorgonian, but gorgonian grows slowly and cannot provide long-term and stable egg attachment protection for Sepiella maindroni de Rochebrune. The present application provides a device for attaching eggs of Sepiella maindroni de Rochebrune using a biological proportioning liquid of gorgonian. The device for attaching eggs using a semi-biological proportioning liquid can attract Sepiella maindroni de Rochebrune by using gorgonian proportioning liquid, and can achieve maximum efficiency by using an automatic shedding structure, so as to maximize the improvement of the egg attachment environment of Sepiella maindroni de Rochebrune.
