Multilayer three-dimensional industrial aquaculture device of standard-thickness whitmania pigra larvae

Abstract

The invention discloses a multilayer three-dimensional industrial culture device of standard-thickness whitmania pigra larvae. The device comprises a fixing frame, a first-layer partition, a second-layer partition and a third-layer partition are fixedly connected on the inner side of the fixing frame, the first-layer partition is positioned below the second-layer partition which is positioned below the third-layer partition, a culture tank is arranged at the top of each of the first-layer partition, the second-layer partition and the third-layer partition, and a net cage is arranged at the topend of the inside of each culture tank. An attaching partition is arranged inside each net cage, and whitmania pigra in each net cage can attach to two sides of the attaching partition, so that convenience is brought to more whitmania pigra to being capable of attaching, and the problem that culture effect of the culture tanks is affected caused by the fact that a lot of leeches are going to haveno place to adsorb or accumulate to lead disease transmission and death after stocking density is high because leeches after intake like to expose out of water with heads upward to adsorb around theculture tanks to help digestion when the culture device is in use is solved.

Description

technical field [0001] The invention belongs to the technical field of leech cultivation, and in particular relates to a multi-layer three-dimensional industrialized cultivation device with thick wide-body golden wire leech seedlings. Background technique [0002] Wide-bodied golden thread leeches, commonly known as leeches, belong to the phylum Annelids, the class Hirudophylum, the order Chloridae, and the family Leechidae. It grows and reproduces in inland fresh waters and is a traditional special medicinal aquatic animal in my country. Leeches contain leech, which can delay and hinder blood coagulation, thus having anticoagulant effect. The leech element extracted from leeches has a very significant effect on dilating blood vessels, reducing blood viscosity, and increasing blood circulation. Now it has developed medicines for treating stroke, high blood pressure, clearing blood stasis, amenorrhea, and bruises, as well as various health products and cosmetics. . The mark...

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of multi-layer three-dimensional industrial cultivation device with wide-bodied golden line leech seedling standard thickness, to solve the problem that when using the cultivation device proposed in the above-mentioned background technology, the leech likes to face up and expose the water surface for adsorption after ingesting. Help digestion around the breeding box. When the stocking density is high, many leeches will have nowhere to adsorb or accumulate in large numbers, causing the disease to spread and die, which will affect the breeding effect of the breeding box. Out of the water, the leeches are easily sucked through the water outlet and die, which affects the survival rate of the leeches
