A Migration Seabed Culture Device and Its Operation Technology

Abstract

The invention discloses a migratory seabed culture device and its operating technology. The device includes a cubic frame group, a boat-type base, ropes and positioning floating balls. The cubic frame group is arranged on the boat-type base. The boat base is connected with the positioning floating ball through ropes, wherein the cube frame group is composed of more than one cube frame. With simple structure and low cost, the device uses seawater flow as the driving force to realize the directional migration of seabed pastures, avoiding the ecological burden on the same sea area, and avoiding abnormal changes in a certain seawater temperature; combined with artificial reefs The flow field effect provides downward seawater flow and continuously supplies seawater rich in seaweed to the seabed farming pasture; combined with the biological effect of the artificial reef, a multi-layered marine pasture is formed.

Description

technical field [0001] The invention belongs to the field of marine aquaculture, and in particular relates to a migratory seabed aquaculture device and an operating process thereof. Background technique [0002] Bottom sowing and multiplication of shellfish refers to the production activities of putting artificial seedlings or semi-artificial seedlings of shellfish on the substrate of waters with suitable environment, and cultivating them through natural growth. Bottom-seeding multiplication mode has many advantages such as the breeding site is located on the seabed where there is no temperature and salinity, the environment is less affected by wind and waves, the habitat water temperature is low and the change is small, and it is suitable for cold-water biological breeding. For example, the scallops multiplied by bottom-seeding are It grows naturally on the seabed at a water depth of about 30 meters, and has become an important economically cultivated shellfish along the co...

Problems solved by technology

However, the high-density sowing of scallop seedlings has caused a great burden on the original ecosystem of the cultured sea area, especially the various microalgae used as food for scallops. Once climate change or other environmental changes occur, it is very easy to cause related algae populations in the cultured sea area The number has dropped sharply, further causing the continuous starvation stress of farmed scallops

In recent years, there have been reports of large-scale disappearance or migration of scallops from related companies that have continued to sow and multiply at the bottom, which has brought huge losses to the local aquaculture industry.
