Improved alga culture apparatus

Abstract

The invention discloses an improved alga culture apparatus. The apparatus comprises a fixing board, floating blocks, a cage frame, a limiting rod and a lower protection net. The fixing board is equipped with the limiting rod in a penetrating manner through a locking bolt. The bottom end of the fixing board is equipped with the floating blocks. The center positions of the floating blocks are equipped with support columns in cavity structures. Inflation chambers are installed between the support columns and the floating blocks. Additionally, two sides of each support column are equipped with airoutlets communicating with the inflation chambers. The bottom end of each position is provided with a connecting rod. Two groups of telescopic rods are installed at the bottom end of the bottom board. The lower protection net is arranged at the bottom end of the limiting rod in the cage frame. Alga seedlings can be delivered in a concentration manner. The apparatus has the structure of preventingbillows. When billows hit, the floating blocks discharge air in order to drive algae to sink. Therefore, loss of algae is reduced. A net cage is formed by the cage frame, an upper protection net andthe lower protection net so that sea fish is prevented from taking algae. The initial protection of seedlings is achieved so that survival rate is increased.

Description

technical field [0001] The invention relates to the technical field of seaweed cultivation, in particular to an improved seaweed cultivation device. Background technique [0002] Seaweed is algae that grows in the sea and is a cryptogamous plant in the plant kingdom. Algae include several different types of organisms that generate energy through photosynthesis. The content of dietary fiber in dry matter seaweed is about 50%, and the protein content is as high as 23.5%. It contains a variety of minerals, and most of the seaweed contains 8 kinds of essential amino acids, taurine, Fe, Zn and other essential trace elements. It is a kind of natural high-quality food raw material with high dietary fiber, high protein and low fat. Seedling planting, this breeding method cannot resist bad weather such as storms and waves, and the algae seedlings hanging on the rope are easily broken by the waves and drift away with the current. Bitten off, pinched off, and because seaweeds in diffe...

[0002] Seaweed is algae that grows in the sea and is a cryptogamous plant in the plant kingdom. Algae include several different types of organisms that generate energy through photosynthesis. The content of dietary fiber in dry matter seaweed is about 50%, and the protein content is as high as 23.5%. It contains a variety of minerals, and most of the seaweed contains 8 kinds of essential amino acids, taurine, Fe, Zn and other essential trace elements. It is a kind of natural high-quality food raw material with high dietary fiber, high protein and low fat. Seedling planting, this breeding method cannot resist bad weather such as storms and waves, and the algae seedlings hanging on the rope are easily broken by the waves and drift away with the current. Bitten off, pinched off, and because seaweeds in different periods have different light requirements, the water layer needs to be adjusted. The seaweed seedlings should be hung a little deeper when they first come out of the warehouse, and the water layer should be gradually raised after the seedlings adapt to the sea environment. , the lifting range should not be too large at one time, but the lifting should be timely and diligent, and it is necessary to manually lift the seedling rope to hang at different heights, which is very troublesome
