In recent years, with some squid and other cephalopods ocean resources growing recession, people study the right-footed past the focus has changed from simple marine resources survey, evaluation of a gradual shift towards the rational utilization of marine resources, protection and breeding by the technical level. Artificial propagation of squid biology research, to solve the pro-body squid fishing, embryo development, seed breeding, adult breeding and rapid fall of current year seedlings squid key technology, with a view to squid and the industrial development of fishery resources in Zhoushan fishing ground to provide repair technical support. 2006 East in Zhoushan fishing ground highly fertilized sea squid caught 6810; hatched juvenile squid 5855, the hatching rate was 86.0%; by the torso of the young squid 20mm long 4182, foster the survival rate was 71.4%; by mantle length 92mm ~ 130mm, weight 106g ~ 219g of squid 2885, 69.0 percent survival rate of aquaculture; through squid rapid breeding and reproductive control, the year 1000 of Health autumn spawning squid 151.6 kg, or 970,200.

In recent years, and so on the partial sea cephalopoda resources day by day declined along with the cuttlefish, the people to the cephalopoda research with emphasis already from the past pure marine resource investigation, the appraisal gradually changed technical stratification planes and so on the marine resource reasonable use, protection and increased reproduction. Through to the cuttlefish artificial propagation biology research, the solution cuttlefish kissed body fishing for, the embryonic development, the seedling plants breeding, the adult fast cultivation and the same year lives the key technologies which the cuttlefish autumn grew seedlings, provided the technical support take the time as cuttlefish's industrial production development and the Zhoushan fishery fishery resources repair.In 2006 east Zhoushan fishery extremely sea area capture cuttlefish fertilized egg 6810 grains; Hatches the young cuttlefish 5855 heads, the hatching rate is 86.0%; Attains torso long 20mm the young cuttlefish 4182 heads, the cultivation survival rate is 71.4%; Attains torso long 92mm~130mm, the body weight 106g~219g cuttlefish 2885 heads, the cultivation survival rate is 69.0%; Through cuttlefish's fast cultivation and the reproduction regulation, 1000 same year lived the cuttlefish autumn to spawn 151.6㎏, gathered 970,200 grains.
