Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] A method for the conservation of fish of the genus Pyramidus based on copper algae cultivation, said method comprising the following steps:

[0033] 1) Determine the maintenance time and select the target sea area;

[0034] The maintenance time is the high temperature season, when other large seaweeds are in the decline period, and the target seaweed scale growth season; the larvae and juveniles of the genus Pyramidus are laid out before the larvae and juveniles arrive at the feeding area at the age of three to four months.

[0035] The selection of the target sea area meets the following conditions:

[0036] ① Feeding grounds with larvae and juveniles;

[0037] ② The seawater depth is within 15-16m, and the transparency is 1-2m;

[0038...

Abstract

The invention belongs to the technical field of maintenance of sebastes fishery, and particularly relates to a sebastes fish maintenance method based on sargassum horneri cultivation. The method comprises the following steps: 1) determining maintenance time and selecting a target sea area; 2) determining a target alga, wherein the target alga is sargassum horneri; 3) constructing algal reef unitsor culture raft frames, and clamping seedlings; 4) laying algal reef units or culture raft frames; 5) performing maintenance effect evaluation on a maintenance sea area; and 6) performing corresponding later-period management according to the maintenance effect evaluation. According to the sebastes fish maintenance method, the proper target alga is selected, the sebastes fishery resources, especially in the larva and juvenile fish stage, are maintained, and very good effects are achieved.

Description

technical field [0001] The invention belongs to the technical field of maintenance of genus genus fishery, and in particular relates to a method for maintaining fish of the genus genus genus based on copper algae cultivation. Background technique [0002] In the far sea area, since there is no natural attachment base in the far sea area and the water depth is relatively deep (15-16 meters), the method of planting algae by bottom sowing cannot be used for maintenance. In the high temperature season (August and September), most of the seaweeds have almost died out, resulting in a shortage of resources, which has brought great trouble to the conservation of the flatfish fishery. At this time, copper algae can grow healthily, therefore, there is an urgent need for a method for fishery resources conservation based on seaweed cultivation. Contents of the invention [0003] In view of the above-mentioned problems, the object of the present invention is to provide a method for th...
