Complex culture device for shellfish and algae

Abstract

The invention discloses a complex culture device for shellfish and algae. The complex culture device for the shellfish and algae is low in requirement for the transparency of seawater in a sea area and can effectively solve the problem that algal reef floats along with waves of the sea surface, so that growth on the algal reef is damaged. The device comprises a balance weight anchor, a shellfish culture floating frame and an algal reef body. The balance weight anchor sinks to a seabed; the shellfish culture floating frame suspends in water and connected with the balance weight anchor through a connecting rope, and multiple shellfish culture boxes are arranged on the shellfish culture floating frame; the algal reef body suspends in the water and located above the shellfish culture floating frame; the algal reef body comprises an algal reef frame body and floating devices arranged on the algal reef frame body which is provided with multiple alga attaching substrate, and the algal reef frame body is connected with the shellfish culture floating frame body through connecting parts.

Description

technical field [0001] The invention relates to the field of shellfish culture, in particular to a shellfish compound culture device. Background technique [0002] Affected by changes in the near-shore marine environment, the transparency of seawater has decreased, the sediment on the attachment base of near-shore rock reefs has increased, the habitat of seaweed is covered by a large number of low coral algae that can adapt to environmental changes, and the near-shore rock reef matrix has a large slope. , leading to the gradual reduction of the space suitable for seaweed habitat. [0003] The current artificial algae reefs are roughly divided into two categories: one is sunken algae reefs, which have very high requirements for the transparency of seawater in sea areas, otherwise it is difficult for seaweeds to obtain suitable light conditions; and they are easily covered by sediments; 2. Floating algae reefs (floating on the sea surface by floating balls, suspending the alg...

Problems solved by technology

[0003] The current artificial algae reefs are roughly divided into two categories: one is sunken algae reefs, which have very high requirements for the transparency of seawater in sea areas, otherwise it is difficult for seaweeds to obtain suitable light conditions; and they are easily covered by sediments; 2. Floating algae reefs (floating on the sea surface by floating balls, suspending the algae reefs in the sea water), this type of floating algae reefs float with the sea waves and are greatly affected by the sea waves, and are easy to damage the algae reefs due to the floating sea waves The algae growing on it; especially when the wind and waves are strong (such as severe weather such as typhoons), the entire algae reef will be destroyed
