Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0014] When implementing the method of the present invention, the hatching device of laying eggs that adopts is as shown in the figure, and it has a net cage body 2, and net rope 1 is arranged above; 60cm, the diameter of the bottom is 40-50cm; the cage body 2 is made of tulle 3 and support 4, and the aperture of the net is 1-2cm; in addition, it is also equipped with an ovipositor.

[0015] The density of temporarily raising brood octopuses is 1-2 / m 3 , water temperature 10-23 ℃, salinity 20-35. Gradually increase the temperature to promote ripening, and feed fresh fish and shrimp. The ovipositors put in are PVC pipes with a diameter of 20-30cm and a length of 30-50cm, ensuring that each octopus has more than two ovipositors. After being stimulated by dry dew, the octopus will hide in the ovipositor to lay eggs and protect the eggs from ha...

Abstract

A method for the oviposition and incubation of poulpe includes such steps as temporary culture of parents, repening the sex gland of parents, arranging ovum collectors which are the PVC tube with 20-30 cm in length, oxytocia, moving the female poulpes along with said ovum collectors in a netted cage, aerating while incubating, collecting larvae, and culturing in pool. Its netted cage for incubation is also disclosed.

Description

technical field [0001] The invention relates to a method for hatching marine cephalopod seedlings in the field of aquaculture, in particular to a method for hatching octopus eggs and a used device. Background technique [0002] Octopus belongs to the phylum Molluscs, Cephalopoda, Order Octabura, and Octopidae. Among them, the true octopus is a species widely distributed in the world. It belongs to medium and large octopuses, grows rapidly, and has a large number of eggs (100,000-600,000 per octopus). Due to a large amount of exports to countries such as Japan and South Korea, my country's original natural resources have declined due to serious fishing. Artificial breeding and release are effective means to protect and increase the amount of resources, and have urgent and practical significance. During the hatching process of the fertilized eggs of octopuses, the parent octopuses have the characteristics of egg protection. They protect their own habitats and hatching places ...
