Artificial breeding method for Octopus variabilis

Abstract

The invention provides an artificial breeding method for Octopus variabilis. The method solves the technical problems that a death rate of existing Octopus variabilis parents is high, an egg laying amount is low, and an egg incubation rate is low. The method comprises the steps such as breeding of Octopus variabilis parents, setting of a breeding pond, egg laying and egg incubation. A gallipot is used as a place for the egg laying and egg incubation of the Octopus variabilis parents; and a series of course control such as water temperature control is conducted. In this way, a survival amount of the Octopus variabilis parents is increased, and thus the egg laying amount and the egg incubation rate of the Octopus variabilis parents can be increased. The method can be widely applied to Octopus variabilis aquaculture.

Description

technical field [0001] The invention relates to an artificial breeding method for aquatic products, in particular to an artificial breeding method for long octopuses, and belongs to the technical field of aquatic breeding and cultivation. Background technique [0002] Long octopus belongs to the mollusk phylum, cephalopods, octopods, and octopidae. It is a common cephalopod in the northern coast of my country. It has the characteristics of rich nutrition and delicious meat. At the same time, it has a good domestic and international market and has a broad Prospects. In recent years, due to the pollution of the marine environment and overfishing, the resources of marine octopus have declined year by year. The artificial breeding of octopus can solve the problem of depletion of octopus resources in the ocean through artificial release, and it is also of great significance to the development of octopus breeding. [0003] At present, in the process of artificial breeding of long...

AI Technical Summary

Problems solved by technology

[0003] At present, in the process of artificial breeding of long octopus, the high parental mortality rate, low egg production and low hatching rate of long octopus have not been effectively solved, making it difficult to form industrialization of long octopus breeding

On the one hand, the long octopus parents generally do not take the initiative to go out to eat bait during the hatching process, resulting in the weak constitution of the long octopus parent during the hatching period. In addition, the long octopus has the nature of fighting with each other, and it is very easy to cause self-mutilation and mutual mutilation, causing carcass and wrist damage. , resulting in the death of the parent octopus; on the other hand, if the residual bait cannot be effectively cleaned up after the parent octopus ingests, the sewage generated will also cause the death of the parent octopus; in addition, the parent octopus is subject to more external disturbances, which will also lead to the death of the parent; The mortality rate of octopus broodstock increases, which reduces the overall egg production in artificial breeding. Fertilized eggs without parental care are prone to mold and fall off in large quantities during the incubation process, resulting in a decrease in hatching rate.
