Whitmania pigra inhabiting and feeding ground

Abstract

The invention discloses a whitmania pigra inhabiting and feeding ground. Using the inhabiting and feeding ground disclosed in the invention, food organisms for the whitmania pigra such as snails are put in a groove body device; the whitmania pigra feeds on the snails in the device; the snail shells are gathered in the groove body device; after feeding on the snails, the whitmania pigra is adsorbedto an inhabiting plate to take a rest; due to shielding of a herringbone sunshade above a top longitudinal brace, the whitmania pigra is not disturbed by the sunshine and can be inhabited nearby quietly, the adsorbing and inhabiting space of the whitmania pigra is increased, and the whitmania pigra does not need to swim in long distance and does not need to search for a habitat again; the snail shells in the groove device body are cleaned regularly, fresh and live snails are fed to the whitmania pigra, the water quality in a water area is kept good to meet the requirements of the whitmania pigra for the water quality, the quantity of the whitmania pigra per unit area is increased, the quality is good, and the risk of disease infection is reduced; and the design is simple, the use is convenient, the effects are good, and popularization value exists.

Description

technical field [0001] The invention relates to the technical field of fishery, in particular to a wide-bodied golden leech habitat and feeding ground. Background technique [0002] Wide-bodied golden line leeches are also called leeches, commonly known as leeches, horse turtles, etc. In terms of animal classification, they belong to the phylum Annelida and the class Hirudophylum. The body is composed of many links, and each body segment is divided into several individual rings. There is a sucker at the back end, which is used for adsorption, feeding and exercise; the wide-body golden leech has high medicinal value, and is mainly used to extract natural hirudin, which has anti-coagulation and thrombolytic effects. In natural waters, the wild leech grows up, the body is flat, slightly spindle-shaped, and the adult body is 6-13 cm long and 1.3-2 cm wide, and the large body width can reach 3.5 cm. cm, the back is usually dark green, with 5 longitudinal stripes formed by altern...

Problems solved by technology

With the development of the medicinal functions of leech spp., the application of leeches spp. has become more and more extensive. The leeches in natural waters are far from meeting the needs. The leeches cultivated artificially have gradually become The first choice for medicinal leeches; breeding wide-bodied golden leech requires frequent feeding of snails and other baits. The traditional way of feeding snails is to spread the snails directly in the water. The bottom of the water is not easy to remove, and it is easy to cause water quality to deteriorate. The wide-bodied golden leech feeds and lives at the bottom of poor water quality for a long time, which is easy to breed diseases; the wide-bodied golden leech has poor swimming ability in the water area, and its feeding range is limited, which is not convenient. Looking for bait organisms such as snails farther away, the range of activities is limited, and they like to inhabit the interface between water and land close to the shore. However, in traditional aquaculture ponds, there are no other things that can be used for wide-ranging except for some attachment bases such as tiles set on the bottom of the water. The golden leech provides habitat and attachment places, which reduces the density of the wide-bodied golden leech per unit of water and limits the production of the wide-bodied golden leech in a unit of water
