Octopus oosperm attaching device

Abstract

The invention relates to an octopus fertilized egg attachment device, which is characterized in that the attachment device is a box body (1) with six surfaces jointed; a corner below the frontal panel of the box body (1) is provided with an inlet / outlet (11) with the size adaptive to the parent octopuses, and an upper corner thereof is provided with a through hole (12); the edges of other three side plates of the box body (1) are provided with external interfaces (14) and through holes (12); the top plate of the box body (1) is provided with a through hole (12) and the soleplate thereof is provided with a sewage drainage hole (15). The attachment device of the invention can protect the fertilized egg and the puerperal parent against the interference and harm of other biology; furthermore, the box body is suitable for the habit of the parent octopuses, can induce the parent octopuses to attach the fertilized eggs to a position relatively concentrated, can attach the fertilized eggs with high efficiency and carry out the artificial propagation of the fertilized eggs and has good attachment performance and high egg hatching rate.

Description

technical field [0001] The invention relates to a special device for attaching fertilized eggs of octopus (octopus), which belongs to the field of aquaculture. The invention can solve the special purpose of attaching the fertilized eggs of octopus parents in natural sea areas and artificial breeding, and is convenient for efficient harvesting of fertilized eggs and artificial breeding and hatching of fertilized eggs. Background technique [0002] The true octopus (Octopus vulgaris Cuvier) belongs to the mollusc phylum Mollusca, and the family Octopodiae, commonly known as "octopus" and "octopus". Rocky reefs, coral reefs, and algae fields; octopuses show negative phototaxis and live in seclusion; they like to eat crustaceans, and they are more active at night or in the evening. The embryos of octopus organisms are directly generated, and the fertilized egg is protected by a glial membrane; the parent body has a special egg-protecting behavior. The research work on octopus ...

Problems solved by technology

The research work on octopus breeding in my country started relatively late and has just started in recent years. So far, the artificial breeding of octopus from fertilized eggs to immature octopus is still limited to the experimental stage, and the breeding of octopus is limited to the collection of wild juvenile octopus. The level of cultivating, and the production of seedlings has always restricted the development of the octopus aquaculture industry; how to create a good ecological environment, so that the fertilized eggs of the octopus (octopus) can be successfully produced and hatched, and the egg production rate can be improved to solve the problem of the fertilized eggs of the octopus. Base (delivery room) is one of the key technologies in seedling production
