Problems solved by technology

[0007] The catch efficiency of fishing gear is affected by the operation time. Within a certain time range, the catch efficiency of fishing gear increases with the extension of the operation time; when the operation time exceeds a certain time range, the catch efficiency decreases with the extension of the operation time

Embodiment 1

[0019] 1. The high-efficiency fishing method for crustacean harmful organisms in the marine treasure breeding reef area is characterized by its appropriate operating time. Including the following process:

[0020] (1) Select a single crab cage and assemble a sinker at the bottom;

[0021] (2) Assemble the ropes 0.5-1.0m deeper than the maximum water depth of the treasure breeding reef area on the crab cage in (1);

[0022] (3) a float is assembled on the top of the rope in (2);

[0023] (4) Place the Pacific herring pieces with a wet weight of 200-300g in the crab cage;

[0024] (5) After placing the crab cages in (4) in the breeding reef area for 40-48 hours, harvest the crab cages.

Embodiment 2

[0026] 1. The high-efficiency fishing method for crustacean harmful organisms in the marine treasure breeding reef area is characterized by its appropriate operating time. Including the following process:

[0027] (1) Select a single crab cage and assemble a sinker at the bottom;

[0028] (2) Assemble the ropes 0.5-1.0m deeper than the maximum water depth of the treasure breeding reef area on the crab cage in (1);

[0029] (3) a float is assembled on the top of the rope in (2);

[0030] (4) Place the shelled mussels with a wet weight of 200-300g in the crab cage;

[0031] (5) After placing the crab cages in (4) in the breeding reef area for 40-48 hours, harvest the crab cages.

Abstract

The invention belongs to the field of propagation and cultivation ecology, and relates to an efficient fishing method for crustacean harmful organisms in a precious-marine-product propagation reef area. The efficient fishing method includes selecting a single-body crab trap and assembling a sinker; assembling a rope on the upper portion of the crab trap, and assembling a floater at the other end of the rope, wherein the length of the rope is slightly larger than the maximum water depth of the precious-marine-product propagation reef area; putting baits for the crustacean harmful organisms of the precious-marine-product propagation reef area into the crab trap, and pulling out the crab trap after the crab trap is placed in the precious-marine-product propagation reef area for 40-48 hours. The efficient fishing method has the advantages that fishing rate of the crustacean harmful organisms in the precious-marine-product propagation reef area can be improved remarkably, costs for control and elimination of the crustacean harmful organisms in the propagation reef area are reduced, management cost for precious-marine-product propagation is lowered, and sound development of the precious-marine-product propagation and cultivation industry is benefited.

Description

technical field [0001] The invention belongs to the field of breeding and breeding ecology. The invention relates to a high-efficiency fishing method for capturing crustacean harmful organisms in reef areas where sea treasures proliferate. The invention can significantly increase the catch rate of crustacean harmful organisms in the multiplication reef area of ​​marine treasures, reduce the cost of controlling crustacean harmful organisms in the multiplication reef area, reduce the management cost of marine treasure multiplication, and is beneficial to the increase of marine treasures. , The healthy development of the aquaculture industry. Background technique [0002] 1. Features of cage fishing gear [0003] Cage fishing gear is an environmentally friendly fishing gear with low energy consumption and less labor, which is suitable for various operating environments. The arrangement of artificial reefs in the sea treasure breeding reef area leads to the diversification of...
