Octopus family parent industrialized cultivation method and special hidden object

Abstract

The invention provides an octopodidae parent industrialized culture special concealment object having the advantages of effectively reducing the mutual injury of the octopodidae parents for propagation and facilitating the collection of the fertilized ovum and having a reasonable structure. The invention also provides an economical and efficient octopodidae parent industrialized culture method through the special concealment object. The octopodidae parent industrialized culture special concealment object comprises a pipe body, wherein the pipe body is formed by connecting a first elbow pipe and a second elbow pipe; and a baffle plate is arranged at the joint of the first elbow pipe and the second elbow pipe. The octopodidae parent industrialized culture method comprises the following steps: feeding the octopodidae parents in a holding pond; and placing the octopodidae parent industrialized culture special concealment object on the bottom of the holding pond. The invention has the advantages of bringing about the natural and reasonable distribution of the parents and reducing the food fight, ensuring good water quality conditions and reducing diseases, benefiting the oviposition ofthe parents in the concealment object, avoiding the possible impact of the air bubble disturbance on the oviposition of the parents, urging the octopodidae parents to deposit the ovum in the special concealment object so as to facilitate the concentrated collection of the operating staff and bring about economical and high efficiency work.

Description

technical field [0001] The invention relates to a method for industrialized cultivation of aquatic animal broodstock and special facilities thereof, in particular to a method for industrialized cultivation of octopidae broodstock and its special concealment. Background technique [0002] Octopus (Octopodidae) is the largest family of cephalopods, commonly known as octopuses. The diameter of eyes on both sides of the head of octopuses is small, and there are four pairs of arms in front of the head and around the mouth, with similar or different lengths. Widely distributed in various sea areas of the world, there are about 140 species. Most of them are shallow sea species, and there are also a few deep sea species. Most of the octopidae have two rows of suckers on their wrists, and some species only have a single row of suckers. Stemization of the right or left third wrist. The top of the wrist is deformed, called "end device", without touching the wrist. Brain oval, smal...

AI Technical Summary

Problems solved by technology

However, the broodstock for breeding purposes must be reared and managed uniformly in large ponds, and mutual mutilation often occurs until only one or two broodstock remain in the pond.

The phenomenon of mutual mutilation has caused a great bottleneck to the broodstock breeding and subsequent breeding of Octopidae, which seriously restricts the large-scale promotion and breeding of this aquatic species.

The prior art, such as the Chinese invention patent application with the application number 200810069661.4, discloses a short and steep breeding method, which adopts the method of cultivating an octopus in each individual cage. Although it can avoid mutual destruction, it also isolates the Contact between broodstock, unsuitable for broodstock for breeding purposes
