Embodiment

[0030] The present invention consists of an anchor 1, a main cable 2, an auxiliary cable 3, an anchor tail rope 14 and a marker float 15 to form an anchoring system; the anchor 1 is fixed on the seabed, and the auxiliary cable 3 is bound on the fixed frame 5 in the middle layer of the fish reef; the floating ball 4 is bound Constitute the fish reef top at fixed frame 5, and floating ball 4 quantity is determined according to fish reef size and weight; The middle layer of the fish reef is formed; the top of the fish reef is connected with the middle layer of the fish reef by connecting ropes 6; the layers of the fish reef are connected by a longitudinal cross-shaped grid 9, which is woven by ropes; the bottom layer of the fish reef is fixed by a circular The frame 5, the horizontal grid 7 and the bottom spherical fish reef 10 are formed, and are connected with the middle layer of the fish reef on the vertical cross grid 9; the middle spherical fish reef 8 has two bumps 11 with h...

Abstract

The invention provides an alga/fish mixed type three-dimensional ecological fish shelter and a feeding method of the fish shelter, wherein the fish shelter comprises an anchoring system, a fish shelter top consisting of a floating ball and a fixed frame, a fish shelter middle layer consisting of a horizontal grid and a fixed frame suspended with a middle spherical fish shelter, and a fish shelterbottom consisting of a horizontal grid and a fixed frame suspended with a bottom spherical fish shelter; and the fish shelter middle layer is respectively connected with the fish shelter top and the fish shelter bottom by a connecting rope and the lengthways crossed grid. The feeding method comprises the following steps of: shipping to a feeding sea area, firstly throwing a first anchor along with the direction of incident flow, sequentially throwing a second anchor by means of fair current, tying an anchor tail rope and a mark float at the back end of the anchor, dragging the anchor tail rope by means of fair current, tensioning a whole system, and completing feeding. According to the invention, the fish shelter can be used for culturing and proliferating the alga with different water depths, is taken as a perching and refuge occasion of the small size medium-upper layer fish and a large size medium-upper layer juvenile fish, and is simple in structure, and convenient to assemble andrecover, so that the novel artificial fish shelter can be provided for building an ecological marine ranch.

Description

technical field [0001] The invention relates to a three-dimensional ecological fish reef mixed with algae and fish, belonging to the technical field of marine fishery. Background technique [0002] With the decline of marine fishery resources, the desertification of coastal waters is becoming more and more serious. Various artificial structures (artificial reefs) set up in the sea by countries around the world have been expected to improve the ecological environment of the sea area, create an environment for marine life to inhabit, and provide fish, shrimp, shellfish, algae and other aquatic organisms with reproductive, growth, and retrieval services. The purpose of protecting the marine environment, improving the breeding effect and increasing the catch is achieved. At present, the construction of artificial reefs has been extensively carried out at home and abroad, and the restoration of offshore marine habitats and fishing grounds has achieved good results.
