Seaweed Farming Tools

Abstract

The invention discloses an algae cultivation tool. The tool comprises a floater, a supporting frame and a balancing weight, wherein the floater, the supporting frame and the balancing weight are connected in sequence through a stay cord, the supporting frame comprises a center rod, a sliding sleeve in sliding connection with the center rod, and multiple fan-shaped supporting plates arranged around the center rod, multiple algae cultivation bricks are arranged on each fan-shaped supporting plate, a connecting base is arranged on the top of the center rod, the fan-shaped supporting plates are connected with the connecting base in a rotary mode on the vertical plane, a supporting rod is hinged between the sliding sleeve and the upper surface of each fan-shaped supporting plate, the sliding sleeve is connected with the connecting base through a tension spring, the corresponding side edges of every two adjacent fan-shaped supporting plates are attached to each other when the sliding sleeve is located at the top dead center of the sliding stroke of the sliding sleeve, and a deflation valve is arranged on the floater. By the adoption of the tool, apposition growth of young algae is facilitated, young algae at the early growth stage are well protected, the survival rate of algae is increased, concentrated releasing is facilitated, and management is convenient.

Description

technical field [0001] The invention relates to the field of seaweed cultivation, in particular to a seaweed cultivation tool. Background technique [0002] Macroalgae grow in the intertidal subtidal zone and subtidal shallow water zone of the mid- and high-latitude seas. As supporting plants, other plankton, swimming animals, benthic animals, and environmental factors that coexist with them constitute the nearshore ecosystem. . Seaweed farms supported by macroalgae have high primary productivity, and at the same time form a complex animal and plant food web that can enrich eutrophic salts such as N and P, restrain the outbreak of "red tide" and protect the marine environment. The economic value created by seaweed farms is great. Seaweed itself has industrial, edible and medical value. Seaweed farms also provide places for fish to seek bait, avoid enemies, and lay eggs. However, according to recent observations, seaweed fields are disappearing, and seaweed biodiversity is ...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to overcome the disadvantages of low initial protection of seaweed seedlings resulting in low seaweed survival rate and inconvenient management in the prior art when seaweeds are propagated in seaweed farms, and provides a method that facilitates the attachment and growth of seaweed seedlings, and is suitable for seaweed seedlings in the early growth stage. It provides better protection for seedlings, improves the survival rate of seaweed, and is convenient for centralized feeding and management of seaweed cultivation tools
