Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of aquaculture facilities, and specifically relates to a composite octopus nest, a breeding pond and an application method thereof. Background Art
[0002] Octopuses have characteristics such as a short life cycle and a fast growth rate, and are one of the most potential protein resources in the ocean. The artificial breeding of octopuses has gradually become one of the research hotspots in the industry. During the mating and spawning stages of octopus parents, nests need to be placed artificially. Currently, the nests used in production, whether they are earthenware pots, polymer tiles or PVC pipes, are all single-type nests, which are only suitable for one octopus to live in, and the three-dimensional space utilization rate of the breeding pond is relatively low. At the same time, octopuses will eat a large amount of food during the mating period to develop gonads, and the remains or shells of fish, shrimps, crabs and shellfish need to be cleaned regularly. Too many nests seriously hinder the cleaning work of the pond bottom. In addition, it has been found in production that male octopuses in the process of mating are easily interrupted by other male octopuses; during the mating process between male and female octopuses, the male octopus is preyed on by the female octopus due to too close mating distance; and the phenomenon of one female octopus mating with multiple male octopuses at the same time. The above phenomena will all reduce the survival rate of octopus parents and the mating success rate. Summary of the Invention
[0003] The purpose of this invention patent is to provide a composite octopus nest to solve the current situation in production where male octopuses in the process of mating are easily interrupted by other male octopuses; during the mating process between male and female octopuses, the male octopus is preyed on by the female octopus due to too close mating distance; one female octopus mates with multiple male octopuses at the same time; and the low three-dimensional space utilization rate of the breeding pond caused by single-type nests.
[0004] This invention patent is realized by adopting the following technical solutions:
[0005] A composite octopus nest is composed of one female octopus nest and three male octopus nests; both the female octopus nest and the male octopus nests are tubular structures. The three male octopus nests are arranged above one female octopus nest. One end of the female octopus nest is open, and both ends of the male octopus nests are open. The cross-sectional area of the tubular structure of the female octopus nest is larger than that of the tubular structure of the male octopus nests.
[0006] As a preferred technical solution, round holes or slits are provided on the left, right and back of the female octopus nest and on the left and right of the male octopus nests.
[0007] As a preferred technical solution, the cross-section of the female octopus nest is a trapezoid, more preferably an isosceles trapezoid; the male octopus nests are three identical cuboids fixed in a "pin" shape. The cross-section of the male octopus nests is a square, and the side length of the square is half of the length of the upper base of the trapezoid.
[0008] Furthermore, the composite nest is made of PC or PVC or any other hard material with a density greater than water, and the size is appropriately adjusted according to the different types of octopuses being bred.
[0009] Furthermore, the upper edge of the female octopus nest and the lower edge of the male octopus nest are provided with a circular hole protrusion, which is used to fix the female octopus nest and the male octopus nest together.
[0010] The invention also provides a breeding pool in which the composite nest is arranged.
[0011] The present invention also provides a method for breeding using the breeding pool, firstly, female octopuses equivalent in number to the composite nests are arranged, and after the female octopuses settle in the female octopus nests, male octopuses 1.5 times the number of the female octopuses are placed.
[0012] The beneficial effects of the present invention compared with the prior art are as follows:
[0013] The present invention arranges the composite nest structure so that the cross-sectional area of the female octopus nest is large and one end is closed. The volume of the female octopus is larger than that of the male octopus. Out of the instinct of choosing safety, the female octopus will actively choose the female octopus nest as the egg-laying base. The male octopus does not have as high a safety demand as the female octopus, is relatively small in size, and prefers a nest with smooth water flow, so it will choose to settle in the male octopus nest.
[0014] The present invention fixes one female octopus nest and three male octopus nests into a group, thereby meeting the demand of mating one female octopus with multiple male octopuses at the same time. In addition, the male octopus and the female octopus have independent spaces and will not be easily interrupted by other male octopuses during mating, thereby reducing casualties caused by fighting between male octopuses for mate rights.
[0015] The present invention arranges the male octopus nest at the top and the female octopus nest at the bottom. During mating, the male octopus stays in the male octopus nest and only extends the stem arms into the carcass of the female octopus in the female octopus nest, thereby avoiding the risk of being preyed upon by the female octopus during mating and improving the survival rate and mating success rate of octopus parents.

[0018] Example 1
[0019] like Figure 1As shown in the figure, a composite octopus nest is composed of a female octopus nest 1 and three male octopus nests 2; both the female octopus nest and the male octopus nests are tubular structures. The three male octopus nests are arranged at the upper end of a female octopus nest. One end of the female octopus nest is open, and both ends of the male octopus nests are open. The cross-sectional area of the tubular structure of the female octopus nest is larger than that of the tubular structure of the male octopus nests. Circular holes or slits are provided on the left, right, and back of the female octopus nest and on the left and right of the male octopus nests.
[0020] Example 2
[0021] As shown in the figure, a composite octopus nest is composed of a female octopus nest 1 and three male octopus nests 2; both the female octopus nest and the male octopus nests are tubular structures. The three male octopus nests are arranged at the upper end of a female octopus nest. One end of the female octopus nest is open, and both ends of the male octopus nests are open. The cross-sectional area of the tubular structure of the female octopus nest is larger than that of the tubular structure of the male octopus nests. Circular holes or slits are provided on the left, right, and back of the female octopus nest and on the left and right of the male octopus nests.
[0022] The cross-section of the female octopus nest is an isosceles trapezoid; the male octopus nests are three identical cuboids fixed in a "pin" shape. The cross-section of the male octopus nests is a square, and the side length of the square is half of the length of the upper base of the trapezoid of the female octopus nest.
[0023] The material of the composite nest is PC or PVC or any other hard material with a density greater than that of water, and the size is appropriately adjusted according to different breeding octopuses.
[0024] Convex circular holes are provided on the upper edge of the female octopus nest and the lower edge of the male octopus nests for fixed connection. After the parent bodies have completely laid eggs, the male octopus nests are removed, and the female octopus nest is transferred to the hatching pool for further hatching.
[0025] Example 3
[0026] Using the composite nest of Example 2 to arrange the breeding of Octopus sinensis in the breeding pool. In the breeding pool, the composite nest described in Example 2 is arranged. First, put in female Octopus sinensis with a quantity equivalent to the number of composite nests. After the female Octopus sinensis settle in the female octopus nests, then put in male Octopus sinensis with a quantity 1.5 times that of the female Octopus sinensis. During the entire mating period, the survival rate, mating frequency, and mating success rate of male octopuses in the breeding pool with the composite nest are significantly higher than those in the breeding pool with the traditional nest. After mating, the egg-laying rate and egg production of female octopuses in the breeding pool with the composite nest are also significantly higher than those in the breeding pool with the traditional nest.
