Problems solved by technology

Practice shows that bamboo tubes and straw traps have the worst fishing effect and have no practical significance; ground cage net fishing and trawl net fishing have certain effects, but the initial catch rate is not high at one time, and most of the leeches in the cultured water body cannot be caught in a short period of time. ;Light fishing at night is the most laborious and labor-intensive, and the efficiency is not high
In short, the existing fishing methods cannot catch most of the leeches in the cultured water body in a short period of time, and cannot effectively solve the problem of leech fishing.

example 1

[0017] Example 1 Leeches were fished in ponds where leeches were cultured in net pens.

[0018] Leech fishing was carried out in a small pool of 500 square meters of net-enclosed cultured leeches. The net enclosure of this net enclosure culture mode is arranged in the water 1 meter away from the pool bank. First reduce the water depth of the pool to 0.5 meters, then remove water plants such as water hyacinths and various floating sundries in the pool, and then mix 375 grams of solid preparations with an effective content of 20 billion active Bacillus subtilis per gram, and mix with water for 15 minutes. After one kilogram, the whole pool is splashed. Then cover a layer of black plastic film on the water surface of the leech breeding water body. After 5 hours, the leeches will float up in large quantities and be adsorbed on the purse net and the plastic film on the water surface. At this time, the leeches can be manually scraped up gently with the hand-made net.

example 2

[0019] Example 2 Leeches were fished in ponds where leeches were raised in cement ponds.

[0020] Carry out leech fishing in the pool of a cement pond with an area of ​​600 square meters for cultivating leeches. First reduce the water depth of the pool to 0.3 meters, then remove water plants such as water hyacinths and various floating sundries in the pool, and then add 270 grams of a solid preparation with an effective content of 20 billion active Bacillus licheniformis per gram, and mix with water for 15 minutes. After one kilogram, the whole pool is splashed. Then cover the plastic foam floating board on the water surface of the leech breeding water body. After 5 hours, the leech will float up in a large amount and be adsorbed on the cement pool wall and the foam floating board on the water surface.

example 3

[0021] Example 3 Harvesting of leeches in ponds where leeches were cultured in cages.

[0022] Leech fishing was carried out in a pond with an area of ​​900 square meters in which the leeches were cultured in pond cages. The characteristic of this cage culture mode is that the pond area is 900 square meters, and the leeches are cultured in the cages arranged in the pond. First reduce the water depth of the pool to 0.3 meters, then remove water plants such as water hyacinths and various floating sundries in the pool, and then mix 405 grams of solid preparations with an effective content of 20 billion active Bacillus subtilis per gram, and mix with water for 15 minutes. After one kilogram, the whole pool is splashed. Then cover the plastic film of one deck black on the water surface of leech breeding net cage. After a few hours, the leeches will float up and absorb in large quantities and attach to the mesh cloth and plastic film around the inside of the cage. At this time, th...

Abstract

The invention provides a leech catching method. According to the technical scheme, the leech catching method comprises the following steps of 1, adjusting the water depth of a leech cultivation pool so that the water level of the leech cultivation pool is controlled at 0.3-0.5 meters; 2, clearing away the float grass and different floating sundries in a leech cultivation water area; 3, uniformly splashing oxygen consumption microbes with a certain solubility in a leech cultivation water body; 4, covering a layer of black plastic film or placing a foam floating plate on the water surface of the leech cultivation water body; and 5, manually collecting leeches which are adsorbed on the pool walls of the periphery of the cultivation water body, the covered plastic film or the foam floating plate by utilizing a microcheiria brail. Through adopting the leech catching method provided by the invention, most of the leeches in the cultivation water body can be caught once, thus the leech catching efficiency is greatly improved, the cost of catching is reduced, and the cultivation economic benefits are improved.

Description

technical field [0001] The invention relates to a leech fishing method, which belongs to the field of special economic animal breeding. Background technique [0002] Leeches, commonly known as leeches, are a general term for the annelida leeches. Leech is a traditional Chinese medicine in my country. It has the effects of breaking blood, removing blood stasis, and dredging menstruation. It is mainly used to treat blood stasis, amenorrhea, bruises, stroke, hypertension and other cardiovascular diseases and tumors and cancers. The type of leech used in Chinese medicinal materials is mainly the broad-bodied golden line leech. At present, the artificial breeding of leeches wide-bodied has achieved initial success. Although the artificial breeding of leeches has been successful, there are still many imperfections. As far as leech fishing is concerned, the current leech fishing methods mainly include ground cage net fishing, trawling net fishing, night light fishing, and bamboo...
