Juvenile sea cucumber and Ciona intestinalis separator for use in sea cucumber culture

Abstract

The invention discloses a juvenile sea cucumber and Ciona intestinalis separator for use in sea cucumber culture. The juvenile sea cucumber and Ciona intestinalis separator comprises separating lines fixed at equal intervals on a support 1; the separating lines 2 are made of nylon or metal wire; spacing of the separating lines is changed according to the growth size of the juvenile sea cucumbers; the diameter of the separating lines is changed according to the growth size of the juvenile sea cucumbers; the support 1 is semi-arc shaped or arrow shaped; the separating lines 2 are symmetrically tensioned on the support 1. The juvenile sea cucumber and Ciona intestinalis separator is simple and reasonable in design, stability of the separator and supporting capacity thereof are greatly improved, the juvenile sea cucumbers and Ciona intestinalis can be quickly separated according to the diameter and size of the separating lines, the spacing of the separating lines and the size of an opening of the support, and the separator is simple in structure, highly practical, time saving and labor saving, efficient and high in use value.

Description

technical field [0001] The invention belongs to the field of sea cucumber cultivation and is suitable for the separation of juvenile sea cucumber cultivation participating in Citronella. Background technique [0002] With the rapid development of the sea cucumber breeding industry, the technology of pest control is relatively lagging behind, coupled with the lack of awareness of prevention, this problem has been aggravated year after year, resulting in serious economic losses. Judging from the survey results of sea cucumber predators, glass sea squirts are important predators in the sea cucumber breeding process. Among sea cucumber predators, glass sea squirts are the most difficult to remove. When they occur in large numbers, they will compete with sea cucumbers for survival in the sea cucumber breeding system. Space and bait consume dissolved oxygen and produce ammonia nitrogen, which has a serious inhibitory effect on the growth of sea cucumbers. At present, there is no e...

[0002] With the rapid development of the sea cucumber breeding industry, the control technology of harmful organisms is relatively lagging behind, coupled with the lack of awareness of prevention, this problem has been aggravated year after year, causing serious economic losses

Judging from the survey results of sea cucumber predators, glass sea squirts are important predators in the sea cucumber breeding process. Among the sea cucumber predators, glass sea squirts are the most difficult to remove. When they occur in large numbers, they will compete with sea cucumbers for survival in the sea cucumber nursery system. Space and bait consume dissolved oxygen and produce ammonia nitrogen, which has a serious inhibitory effect on the growth of sea cucumbers. At present, there is no effective method to control the occurrence of glass sea squirt populations, which is a major problem that plagues sea cucumber farming.

Because its living environment is the same as that of sea cucumbers, and it is easy to deteriorate the water body environment, and it is easy to cause sea cucumbers to "dirty" or even die. In the field of seafood farming, glass sea squirts often occur in the breeding ponds in the later stage of juvenile ginseng cultivation. Inverting the tank can easily cause Ciona to grow on the pool wall or on the attachment base. At present, because Ciona is biologically similar to sea cucumbers, the drugs that kill Ciona will also affect the growth and reproduction of sea cucumbers, so there is no effective one. The method of removing Ciona with drugs, if it is found that there are sea squirts attached to the culture system, manually remove them if necessary

This not only wastes a lot of manpower and material resources, but most of the manual removal methods are manual removal, the process is complicated and slow, and it is easy to cause sea cucumbers to be exposed to the air for too long and mechanically damage the sea cucumber skin, which is very harmful to sea cucumbers.
