Problems solved by technology

The artificial fish reef in this application also did not consider how to form different flow field environments on the seabed through the artificial fish reefs put in, and how to stir the seabed sediments through the artificial fish reefs, so that the nutrients deposited on the seabed can rise, and improve the quality of the artificial fish. The primary productivity of the sea near the reef provides sufficient bait for fish

Embodiment Construction

[0025] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0026] like figure 1 Shown, a kind of multifunctional artificial fish reef comprises reef body 1, floating ball 15, connecting rope 14, the reef body cavity 2 that is arranged in reef body and some are arranged on the side of reef body, and the inlet and outlet that communicate with reef body cavity 5. The bottom surface of the reef is flat. The top surface of the reef body is plane, and the top surface of the reef body is parallel to the bottom surface. The cross-section of the reef is circular. The top surface of the reef body is provided with installation grooves, and each installation groove is respectively provided with algae reef blocks 4 that have been cultivated in a laboratory and attached to seaweed sporophytes. The algae reef block is fixed on the reef body by bolts.

[0027] The outer surface of the reef body extends obliquely d...

Abstract

The invention discloses a multifunctional artificial fish reef, and aims to provide an artificial reef which is beneficial to formation of different flow field environments with upwelling, can raise nutrient substances deposited at the seabed, can improve the primary sea field productivity near the artificial reef and can provide sufficient feed to fishes. The multifunctional artificial fish reef comprises a reef body, an inner reef cavity and a plurality of inlets and outlets, wherein the inner reef cavity is arranged inside the reef body; the plurality of inlets and outlets are formed in the side surface of the reef body and are communicated with the inner reef cavity; the outer side surface of the reef body extends downwards from top to bottom towards the outer side of the reef body in an inclined manner; a partitioning plate which extends upwards and downwards is arranged inside the inner reef cavity.

Description

technical field [0001] The invention relates to the field of fish reefs, in particular to a multifunctional artificial fish reef. Background technique [0002] Due to the deterioration of the marine environment and the over-exploitation and destruction of marine fishery resources, it is imperative to improve this problem through artificial means. Among them, artificial fish reefs are used to improve the ecological environment of the sea area and create a habitat for marine organisms. It has achieved good results in providing places for shelter, growth and reproduction, etc. for fish. [0003] Present artificial fish reefs are usually made of objects such as stones, concrete blocks, and discarded vehicles and boats. The current design of artificial reefs is mainly aimed at how to provide shelter, growth and reproduction places for fish, etc.; however, little consideration is given to how to form different flow field environments on the seabed through artificial reefs, and ho...
