Embodiment

[0018] Example: 1. Preparation of Adhesive Base Material and Adhesive Base Material Premix

[0019] When preparing the attachment base material, the aquatic waste shells are crushed to a particle size of 2-5 cm for use.

[0020] When preparing the adhesive base material premix, add one or more of adhesive or cement, river sand, water or organic solvent, and alum, and mix well.

[0021] Preparation of mussel attachment base material and mussel attachment base material premix

[0022] Aquatic waste mussel shells were crushed to a particle size of 4 cm for use. During preparation, mix 750 kg of cement, 500 kg of sand, 900 kg of mussel shell fragments with a particle size of 4 cm, 45 kg of alum, and 500 kg of water.

[0023] Preparation of oyster attachment base material and oyster attachment base material premix

[0024] Aquatic waste oyster shells were crushed to a particle size of 4 cm for use. During preparation, mix 750 kg of cement, 500 kg of sand, 900 kg of oyster shell...

Abstract

The invention discloses a floating artificial fish reef. During preparation, the floating manual fish reef is characterized in that an adhesion base material is bonded to a floating body material and a suspender by using an adhesive or cement, the suspender is suspended below the floating body material after being cured, and a counter weight is suspended below the suspender. The floating artificial fish reef is arranged on the euphotic layer of sea water in an aquaculture zone, so that the adhesion growth of algae, shellfishes and microorganisms is facilitated, the water quality of the aquaculture zone is improved, and the generation of eutrophication is inhibited.

Description

technical field [0001] The invention relates to an artificial fish reef which is especially suitable for preventing and controlling water eutrophication around marine aquaculture areas and providing attachment bases for algae, shellfish and microorganisms, in particular to a floating artificial fish reef. Background technique [0002] Cage culture is a fine farming model with high yield and good benefit. It has been widely developed in countries all over the world since it came into being in the 1970s. However, with the continuous expansion of the scale of cage culture, the environmental pollution caused by residual bait and various metabolic wastes caused by cage culture, especially the problem of nitrogen and phosphorus eutrophication, has received widespread attention from all countries in the world. Water quality has deteriorated, water biodiversity has decreased, Red tides and the death of farmed fish have hindered the healthy development of cage culture. [0003] Arti...
