Embodiment Construction

[0007] The invention temporarily raises the hatched golden squid for 5 to 20 days, makes the length of the back of the squid 0.5 to 1.5 cm, and dyes the inner shell of the golden squid. When dyeing, the dye is dissolved in fresh water to make an aqueous solution of the dye. Described dyeing agent is alizarin complex indicator, and it is a kind of yellow powder, easily soluble in water, and aqueous solution is purple, and English name Alizarin Complexone, is called for short ALC, chemical name 3-[N, N-Bis (carboxymethyl) aminomethyl]-1,2-dihy-oxyanthraquinone, molecular formula C 19 h 15 NO 18 Put into the aqueous solution of above-mentioned dyeing agent in the container that fills golden squid and seawater, make the concentration of dyeing agent in seawater be 60~80ppm, soak 20~28 hours. During operation, reduce the water level of seawater in the breeding water tank, and raise the breeding density of the above-mentioned cuttlefish to 10000 tails / m 3 . Add an aqueous solut...

It is widely distributed in the Far East Sea of ​​Russia, Honshu, Shikoku, and Kyushu of Japan, the west coast, south coast of North Korea, and the waters of the Philippine Islands. In my country, it is mainly distributed in Shandong Rizhao Lanshantou, Qingdao, the middle and north of the Yellow Sea. Golden squid has a short life cycle, fast generation renewal, rapid growth, wide appetite, delicious meat, high protein content, and a wide range of comprehensive utilization. It is an excellent species with high economic value. It was once one of the four major marine fisheries in my country. However, after the 1980s, the environment and production order of golden squid spawning grounds and multiplication protection areas were destroyed. In...
