Double-harvest-one-year industrialized culture method for octopuses

Abstract

The invention discloses a double-harvest-one-year industrialized culture method for octopuses, which comprises the following steps of: cultivating parent octopuses in a strengthened mode, laying eggs, hatching fertilized eggs, cultivating young bodies, cultivating adults at a controlled temperature and the like. The method can stabilize and improve the physical quality of the parent octopuses, reduce mutual killing, effectively reduce the diseases of the fertilized eggs and improve hatchability. Furthermore, an adopted octopus industrialized cultivator for the fertilized eggs of the octopuses can be conveniently moved, so that cost is low, sterilization and desinsection can be performed by a high concentration medicated bath, the infringement of parasites to the octopus eggs which have relatively long hatching periods can be greatly reduced, and the adopted octopus industrialized cultivator is particularly suitable for hatching the octopus eggs on a large scale. By adopting hidden matters, the energy loss of octopus young bodies caused by swinging can be reduced, and the growth speed of the octopus young bodies can be improved. Male and female octopuses are bred in an isolated mode in the step of cultivating the adults at the controlled temperature, so that the mutual killing and energy loss caused by mating can be avoided, and the weight increment of finished octopuses is facilitated. The double-harvest-one-year industrialized culture method for the octopuses has the advantages of industrialization value, short production period, high hatchability and fewer diseases.

Description

technical field [0001] The invention relates to a technology for industrialized aquatic product heating and cultivation, in particular to a method for industrialized cultivation of octopuses with two crops a year. Background technique [0002] Most octopuses are shallow-sea species, and there are also a few deep-sea species. The inner shell of the octopus is degenerated, only two small shell needles remain on both sides of the back, and there is no light emitter. Females have 1 pair of fallopian tubes. It mainly lives on the bottom of the sea and crawls on the bottom of the sea. It can also swim in the bottom seawater for a short time by virtue of the reaction of the water sprayed by the funnel. It has short-distance reproductive and overwintering migration habits, and feeds on lobsters, shrimps, crabs, shellfish and bottom fish. It is often prey for sharks, moray eels, etc. The amount of eggs laid by different species of octopus varies greatly, ranging from a few thousa...

AI Technical Summary

Problems solved by technology

The implementation of artificial large-scale culture of octopus is of great significance to increasing new species of seawater culture and improving economic benefits. However, there is no relevant literature disclosing the multi-crop culture technology of octopus.
