Manufacturing and using method for artificial fish nest and artificial algae facilitating rapid and multiple fish births

Abstract

The invention discloses a manufacturing and using method for an artificial fish nest and an artificial algae facilitating rapid and multiple fish births. The method comprises the steps that ultrafine fiber artificial seaweeds are adopted for manufacturing the artificial fish nest or algae, and an artificial fish nest field or an artificial algae forest is formed in a target water area. The artificial fish nest attracts various kinds of fishes for egg laying, fertilization and incubation, the artificial algae can alleviate sea area eutrophication, the good living environment is created for marine animals such as fish and shrimps, the water area biological diversity is increased, and the purposes of improving and stabilizing the sea area ecological environment, repairing fishery resources and improving the sea area economic benefits are achieved.

Description

technical field

[0001] The invention relates to aquaculture technology, in particular to a method for making and using an artificial fish nest or artificial seaweed that can promote fish reproduction and improve the living environment of fish. Background technique

[0002] Nowadays, due to changes in the ecological environment of rivers and lakes, the aquatic plants that fish rely on to breed and spawn have basically disappeared, the environment suitable for fish breeding is decreasing, and the natural fishery resources are seriously declining. Factors such as the degradation of natural fishing grounds have caused a serious decline in marine fishery resources and a serious decline in the productivity of inshore fisheries. Fishing has to go to distant waters, and often even causes international disputes.

[0003] In freshwater waters, in order to promote the natural proliferation of indigenous fish, the fishery management departments of many places have placed a large number ...

Examples

Embodiment 1

[0036] A method for making and using an artificial fish nest and artificial seaweed to help fish grow more and faster, the method is as follows:

[0037] (1) Refer to figure 1 , buckle the longitudinal central rope of superfine fiber artificial aquatic plants on the porous bricks, buckle 2 to 5 artificial aquatic plants on each porous brick to make artificial fish nest clusters; the length of the superfine fiber artificial fish nests is 0.5 to 2m ;

[0038] (2) Transport the manufactured artificial fish nest clusters to the target water area, and put them into the water according to the density of the artificial fish nest clusters at an interval of about 1m to form an artificial fish nest field; the artificial fish nests are laid in sheets, and the area of ​​each sheet is 20m 2 Left and right, the interval between each artificial fish nest field is 10-30m.

[0039] During the breeding season, fish and shrimps lay a large number of eggs on the superfine fiber artificial fish...

Embodiment 2

[0042] A method for making and using an artificial fish nest and artificial seaweed to help fish grow more and faster, the method is as follows:

[0043] (1) Refer to figure 2 , connecting the head and tail of superfine fiber artificial aquatic plants to form artificial seaweed strings, buckle the central rope at the end of the artificial seaweed strings on the concrete components, and buckle 3 to 5 artificial seaweed strings on each concrete component to form artificial seaweed clusters; The length of the superfine fiber artificial seaweed is 30m, which is formed by connecting 30 1m long superfine fiber artificial seaweed heads and tails in series, and each connection part has a floating ball grass head;

[0044] (2) Transport the manufactured artificial seaweed clusters to the target sea area, put them into the water according to the density of the artificial seaweed clusters at an interval of 3 to 10m, and form artificial seaweed forests; the artificial seaweed forests are...

Embodiment 3

[0046] A method for making and using an artificial fish nest and artificial seaweed to help fish grow more and faster, the method is as follows:

[0047] (1) Refer to image 3 , put one or several stones in the net bag, buckle the central rope of the tail of the superfine fiber artificial seaweed on the stone net bag, buckle 3 to 5 artificial seaweeds on each stone net bag, and make artificial seaweed clusters; The length of the superfine fiber artificial seaweed is 40m, and it is formed by connecting 40 superfine fiber artificial aquatic plants with a length of 1m head to tail, and each connection part is provided with a floating ball grass head;

[0048] (2) Transport the manufactured artificial seaweed clusters to the target sea area, put them into the water according to the density of the artificial seaweed clusters at an interval of 3 to 10m, and form artificial seaweed forests; the artificial seaweed forests are laid in pieces, each with an area of ​​200m 2 The interval...
