Embodiment 1

[0033] A method for preventing birds in aquaculture ponds with buckle crabs.

[0034] Breeding object: Eriocheir sinensis young crabs, with a breeding area of ​​15 mu.

[0035] Major bird damage: egrets, herons, gray herons and other wading birds.

[0036] Preparation of materials: 100 bamboo poles (3.5 meters in length, 8 cm in diameter), polypropylene thread (No. 4 thread, 600 meters / kg), and 300 nylon threads (0.3mm).

[0037] (1) Dig pits with a diameter of about 10cm and a depth of 50cm at equal intervals on the sides 610 and 620 of the crab pond 600, put the bamboo pole 100 in, then put in a little broken bricks and compact it with soil to ensure that the bamboo pole 100 will not shake , forming two rows of piles 100a, 100b, as the main support of the bird-proof net, the distance between the adjacent two bamboo poles 100 of each row of piles 100a, 100b is 5 meters;

[0038] (2) Tie the polypropylene thread 200 on the bamboo pole 100 of each row of pile bodies 100a, 100...

Abstract

The invention relates to an ecological bird-preventing method for an aquaculture pond. The ecological bird-preventing method comprises the following steps of: (1) installing pile bodies, serving as a main bracket of a bird-preventing net, on the two sides of the culture pond, wherein the spans among the pile bodies are 50 to 100 meters, the spaces among the pile bodies are 4 to 6 meters, and the underground embedding depth of the pile bodies is 50 to 100 centimeters; (2) binding main ropes on the pile bodies, wherein the distance between the main rope and the ground is 2 to 3 meters; (3) binding nylon ropes on the main ropes, wherein the nylon ropes stretches across the culture pond, and the spaces among the nylon ropes are 35 to 50 centimeters; and (4) tightening the nylon ropes. The method disclosed the invention is low in cost, convenient to operate and suitable for aquaculture enterprises and farmers to use. The method can prevent birds from eating cultured aquatic products on the premise of not hurting the birds, the bird-preventing rate is over 80%, and the predation of the cultured aquatic products and the spread of diseases caused by the birds are reduced.

Description

technical field [0001] The invention relates to a method for preventing birds, more specifically, relates to an ecological method for preventing birds in aquaculture ponds. Background technique [0002] my country's aquaculture industry has developed vigorously in recent years. According to statistics in 2010, the output of aquaculture aquatic products accounted for 75% of the total output of aquatic products, far exceeding the output of fishing. With the development of the aquaculture industry, the impact of bird damage on aquaculture has become increasingly more and more cannot be ignored. [0003] Birds often choose places close to water sources as habitats. At the same time, some migratory birds also use breeding ponds as an ideal resting place during migration, so that the surrounding ponds become a gathering place for birds, and the breeding objects in the ponds also If it is included in their predation range, the resulting loss has to be paid attention to by farmers. ...
