Reef type circulating egg-holding device suitable for cuttlefish reproduction and application method thereof

Abstract

The invention discloses a reef type circulating egg-holding device suitable for cuttlefish reproduction and an application method thereof. The reef type circulating egg-holding device suitable for cuttlefish reproduction includes a substrate, a main shaft and a plurality of egg-holding frames, wherein the substrate is provided with the main shaft; the egg-holding frames are hung from the bottom tothe top, and can be arranged on a large water surface; shaft sleeves sleeve the main shaft, and the number of the shaft sleeves can be adjusted according to requirements; and each shaft sleeve is connected to one egg-holding frame, and a plurality of egg-holding frames can be arranged on one main shaft. The reef type circulating egg-holding device suitable for cuttlefish reproduction can be combined into a line-shaped, net-shaped or surface-shaped structure by using lines, a plastic net or rough surface materials, thus being able to simulate an environment of gorgonian and achieving the effect of promoting egg laying for cuttlefish.

Description

technical field [0001] The invention relates to the field of egg attachment, in particular to a reef-type circulation type egg attachment device suitable for squid reproduction and an application method thereof. Background technique [0002] With the development of the squid breeding industry, the supply of artificial seedlings of squid is also increasingly in short supply. How to improve the egg collection rate and hatching rate in the squid breeding process is the key to improving the artificial seed production and realizing the large-scale seed cultivation. Appropriate squid egg collection and hatching devices are the basis for improving squid spawning rate and hatching rate. At present, most squid indoor egg collection adopts mesh-type incubators. This egg-picking device only hangs the mesh with frame support into the water body from above the water body to collect eggs. Due to the habit of spawning on corals, the effect of collecting eggs is not good; 2. It cannot be ...

Problems solved by technology

At present, most squid indoor egg collection adopts mesh-type incubators. This egg-picking device only hangs the mesh with frame support into the water body from above the water body to collect eggs. Due to the habit of spawning on corals, the effect of collecting eggs is not good; 2. It cannot be reused, and a new egg collector must be remade every time an egg collector is used up; 3. It is not suitable for large water surfaces. It is difficult to hang the mesh down; this technology has invented a reef-type circulating egg attachment device for squid reproduction and its use method, imitating the spawning scene of the natural environment of squid to prepare reef-type device attachment eggs to improve the egg collection rate; On the other hand, the slot-type attachment egg base fixing device is adopted, and the incubator can be used repeatedly; moreover, the egg attachment device adopts a vertical adjustable bracket, which does not need to find a support point from above the water body, and at the same time, the position of the attachment egg base in the water layer can be adjusted. location for squid spawning
