Embodiment Construction

[0023] The technical solution of the present invention will be further explained by the following examples, but the protection scope of the present invention is not limited in any form by the examples.

[0024] A cofferdam multiplication method of sargassum, it comprises the following steps:

[0025] 1) Site selection for the intertidal proliferation sea area: choose an intertidal zone with small wind waves, relatively tortuous coastline, and a water depth of about 30cm after ebb tide, and the bottom of the sea area is a reef with few other large algae.

[0026] 2) Arrangement of the attachment base: Use the reef with the natural bottom of the selected sea area as the attachment base for seedlings, scrub the surface of the reef clean, and make it flat on the bottom of the water after a little arrangement.

[0027] 3) Construction of cofferdams: when the tide is low, use flood control sandbags and waterproof mortar to build cofferdams in the intertidal zone in selected sea area...

Abstract

The invention discloses a cofferdam multiplication method of sargassum thunbergii and belongs to the technical field of restoration of biological resources. By the cofferdam method, sargassum thunbergii seedlings are directly multiplied in the intertidal zone, so that the problem that an existing sargassum thunbergii multiplication method is high in cost and operation difficulty and poor in multiplication effect is solved.

Description

technical field [0001] The invention belongs to the technical field of biological resource restoration, and in particular relates to a cofferdam multiplication method of sargassum. Background technique [0002] Macroalgae are mainly distributed in the intertidal and subtidal shallow waters of several meters near the coast of the ocean. They are the most important primary producers in the offshore and play a very important role in the offshore carbon cycle. The seaweed field formed by the distribution of various seaweeds can provide a place for foraging, habitat, spawning and hatching for various marine animals, forming a typical ecosystem with rich biodiversity, and playing a fundamental role in offshore ecology. [0003] Sargassum is an important macroalgae widely distributed in my country. It not only has important economic value, but also is an important part of coastal seaweed farms. However, due to the destruction of human activities such as land reclamation, port cons...
