Technical Field

The invention belongs to the technical field of mariculture, and particularly relates to a combined hanging frame for cultivating seaweed seedlings.

Background

For a long time, various marine cultivations basically adopt shells as substrates to collect and cultivate seedlings in different forms, and especially the seedling cultivation of red algae. At present, the use of sea farming on shells is carried out in almost two ways:

the first is that the shell is not punched, the seedling is picked in a flat spreading mode, and the shell is discarded after the seedling is picked (such as the porphyra yezoensis seedling raising);

the second is that the shell is perforated and fixed on the steel rope by string (or other fixing) method, which can complete the whole process from seedling collection to cultivation (such as the collection and cultivation of oyster, porphyra haitanensis and other animals and plants).

Both of the above methods are currently in production, but the problems are more prominent. For example, put or string hang the shell and need consume a large amount of manpowers, the management during seedling collection is comparatively loaded down with trivial details, and the shell is easy damaged and produce the dark split when punching, and the rope breakage easily appears in the sea wind surge, leads to breeding the variety and loses and the material is mostly the extravagant very big scheduling problem of disposable.
