Background

Octopus vulgaris belongs to the phylum mollusca, the class of cephalopoda, the order of Octagales, the family of Octopaceae, the genus of Octopus, commonly known as octopus and Octopus vulgaris, is a species commonly seen in the world, is widely distributed in temperate sand-bottom and rocky reef sea areas in China, such as coastal areas, Japan, Rex domestica, Australia, Atlantic areas, Mediterranean areas and the like, is an important economic octopus vulgaris in coastal areas of China Minyue, and has fresh and tender meat, rich nutrition and delicious taste. In recent years, due to over-fishing and the change of ecological environment, natural resources are less and less, the demand of market consumption on cephalopods is increased year by year, and the supply and demand relationship is seriously unbalanced, so that the octopus culture has attracted wide attention as an important means for resource recovery. Octopus vulgaris has strong adaptability to the culture environment, wide distribution, high egg laying amount, rapid growth and high nutritive value, and becomes the most popular culture object and research hotspot in the head-foot.

In the actual cultivation process of the octopus ocellatus, the demand of octopus ocellatus seedlings for nutrition is very large, so in the seedling growth process, the seedlings cultivated in the same batch are difficult to avoid large individual difference caused by unbalanced nutrition intake. However, the octopus ocellatus can be killed mutually in the seedling stage or the growth stage, and is mainly characterized in that the young octopus ocellatus with larger individuals can attack and eat the young octopus ocellatus with smaller size. In addition, the research finds that the argonanthus ocellatus of similar specifications is cultured in the same environment, fighting behaviors of the argonanthus ocellatus are obviously reduced, and the survival rate of the argonanthus ocellatus is obviously superior to that of the argonanthus ocellatus of different specifications in mixed culture. Therefore, the method for avoiding the seedling killing is to sieve the seedlings with different sizes and specifications, separately feed the seedlings and carry out grading treatment on the seedlings so as to reduce the overlarge individual size difference of the seedlings as much as possible.
