Problems solved by technology

As one quickly sees, this idea is inefficient and only multiplies in one direction, but only removes or destroys the reef when the population becomes too dense

Embodiment

[0016] Example: refer to figure 1 , self-submerged fish reef multiplication method, it has the following steps:

[0017] 1. attach eggs: put the atoll 21 of the self-sinking fish reef into the waters where seedlings are abundant;

[0018] ②Transplanting: Combine the atoll 21 in step ① on the self-sinking fish reef device and put it into the sea area to be multiplied;

[0019] 3. population strengthening: inject seawater containing seaweed or shellfish seedlings into the multifunctional tube 15 of the self-sinking fish reef device of step 2;

[0020] 4. Variety change: as needed, inject saturated calcium hypochlorite solution through the multifunctional tube 15; carry out step 3. operation after one week; also can adopt other poisonous, low-residue chemical preparations that can kill aquatic animals. cannot be listed one by one.

[0021] The self-sinking fish reef has a self-sinking support 1; the self-sinking support 1 contains a platform 13; a trapezoidal support frame is ...

Abstract

The invention discloses a self-sinking fish reef proliferation method which comprises the following steps: (1) attaching eggs; (2) transplanting; (3) enhancing populations; and (4) changing varieties. A self-sinking bracket of a self-sinking fish reef comprises a platform; a ladder-shaped bracket frame is arranged below the platform; the bracket frame is formed in a way that side supporting rods on the side surfaces are connected with bottom supporting rods at the bottom; limiting columns are arranged at the parts on the inner sides of the side supporting rods below the platform; an upwardly projected positioning boss is arranged on the platform; a multifunctional pipe is arranged in a position of the positioning boss, close to an edge opening; a combined reef body is arranged above the platform; the combined reef body comprises an annular reef matched with the edge opening of the positioning boss; through positioning holes capable of accommodating pins are formed in positions close to the side surfaces at the top or the bottom on the annular reef; and the bottom supporting rods can be of a rectangular structure formed by the four bottom supporting rods and can be also ring-shaped. The self-sinking fish reef proliferation method has the advantages of high laying speed, stability for laying, high proliferation efficiency, high success rate and capability of changing the proliferation varieties according to the need.

Description

technical field [0001] The invention relates to a method for multiplying artificial fish reefs, in particular to a method for multiplying self-submerged fish reefs. Background technique [0002] Artificial fish reefs refer to specially constructed fishery engineering facilities in waters where fish swim through caves, have suitable natural conditions and do not hinder other operations. The purpose of the artificial reef is to improve the ecological environment of the water area, attract fish to gather, breed or feed and grow, thereby forming a stable fishing place. In addition, there are artificial reefs specially set up to protect fish resources, cultivate larvae or induce fish schools to swim in a directional way. Humans have built artificial reef fisheries dating back to the 19th century. As early as 1860, American fishermen discovered the role of reefs. The United States and Japan are the countries with the earliest history of artificial reef construction, large scale...
