Full-automatic temporary tubificidae culturing device

Abstract

The invention provides a full-automatic temporary tubificidae culturing device which comprises a culturing tank. A water feed system is communicated with the culturing tank. A transversely-forced swing frame is arranged in the culturing tank. One of the faces of the culturing tank is provided with a water overflow opening. A water receiving tank is formed in the lower portion of the water overflow opening outside the culturing tank. The bottom of the water receiving tank is movably fixed. The water receiving tank can rotate with a connection point as an axis. One end of the transversely-forced swing frame is connected with the water receiving tank through a pulling line. The other end of the transversely-forced swing frame is connected with a balance weight outside the culturing tank through the pulling line. The water receiving tank rotates in the direction of being away from the culturing tank to drive the transversely-forced swing frame to move and enable the balance weight to ascend in the vertical position, and the balance weight descends in the vertical position to drive the transversely-forced swing frame to move and enable the water receiving tank to rotate in the direction of being close to the culturing tank. By means of the full-automatic temporary tubificidae culturing device, high-density temporary culturing can be conducted on tubificidae, the transversely-forced swing frame is pulled under the action of the gravity of the body of water in the water receiving tank to conduct reciprocating swing, the dissolved oxygen of the culturing water body is increased, the highly-concentrated tubificidae can be dispersed, and it is avoided that the tubificidae gathers together in a highly-concentrated mode and dies due to lack of oxygen.

Description

technical field [0001] The invention belongs to the field of facility fishery, and in particular relates to a fully automatic water worm temporary breeding device. Background technique [0002] Water earthworms, also known as silk earthworms and red nematodes, belong to the aquatic oligochaetes of the phylum Annelida, and usually live in the sludge at the bottom of rivers. The nutrition of water earthworm is comprehensive, its dry product contains 62% of crude protein and 35% of various essential amino acids, so it is regarded as an ideal bait for various aquatic animals. [0003] However, under the conditions of artificial breeding, there will often be a phenomenon that the water worms die in large numbers due to the local environmental hypoxia caused by the high clustering of water worms. The death rate and amount of death have also increased the possibility of disease outbreaks for farmed aquatic animals due to feeding on spoiled water earthworms, seriously affecting the...

[0003] However, under the conditions of artificial breeding, there will often be a phenomenon that the water worms die in large numbers due to the local environmental hypoxia caused by the high clustering of water worms. The death rate and amount of death have also increased the possibility of disease outbreaks in aquatic animals due to feeding on spoiled water earthworms, seriously affecting the healthy growth of aquatic organisms in farming
