Study on Octopus sinensis and its Breeding

Octopus sinensis,commonly known as Octopus and Red Octopus,is mainly distributed in temperate,subtropical and tropical seas.It is an important economic species in southern China,with characteristics of fast growth,strong reproduction and high economic value.The daily growth rate of body weight is 13%,the food conversion rate is 15%-43%,the 80 g larvae can grow to 1500 g after 3 months of breeding,and the spawning capacity of mature females is 60000-200000,which is suitable for large-scale breeding and breeding,and is one of the hot spots in international cephalopod breeding and development.Due to the long incubation period and complex technology,no mature seedling cultivation technology has been established,which restricts the industrialization of squirts.In the process of squirts breeding,it is the key to find a suitable feed for the late planktic stage of squirts.In the absence of suitable feed,we can try to take advantage of the phototactic ability of squirts and feed a small amount of shredded Opossum shimp when squirts flock together.The key to protecting the larvae is to provide a suitable hiding place for them at the bottom of the pond.In practice,stones and oyster shells can be piled on the bottom of the pond to provide a hiding place for them,and the effect of oyster shells is better than that of stones.
