Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to industrial production and management of fish and shellfish, and more particularly to administration of a hibernation inducer to fish and shellfish to reduce the physiological activity of the fish and shellfish, and to preserve or transport the fish and shellfish. The present invention relates to an automatic hibernation inducing device used in a case where the hibernation state is suitable.

2. Description of the Related Art At the present time, seafood on a general dining table is roughly classified into seafood caught in the inside and outside oceans and seafood grown by aquaculture.

[0003] Biological accumulation of harmful substances due to pollution of the global environment has been recognized in so-called natural fish and shellfishes caught in the inner and outer oceans. In addition, not only fish and shellfish contaminated by environmental pollution, but also a large number of those infected with viruses have been recognized. In recent years, these viruses have been shown to be affected by sudden changes in host specificity, as evidenced by the AIDS and Ebola viruses. Notwithstanding, the development of vaccines against these mutant viruses is far behind for the economics of the pharmaceutical industry, raising doubts about the safety of these seafood as human food . In addition, when focusing on the safety of human food, the presence of bacteria that infect these fish and shellfish and the presence of parasites that are parasitic inside and outside the body cannot be ignored.

On the other hand, in cultured fish, the spread of the disease is chronic, and a large amount of antibiotics is administered to a culture pond where the cultured fish grows, so that the emergence of antibiotic-resistant pathogens is inevitable. At present, there is a cyclical contradiction that a new antibiotic against this new resistant bacterium is always required.

[0005] In addition, the release of salmon and trout into a river results in a decrease in survival rate and the occurrence of malformation because these fry are genetically fertilized by closely related individuals. Since the genetic load is large in population genetics as described above, artificial bias is applied to the natural environment, and this has become a major problem from the viewpoint of species conservation.

[0006] Under the current situation, it is desirable that fish and shellfish to be served as human food be placed under an orderly and controlled system, that is, it is desirable that the shellfish and shellfish be domesticated. For example, if it is possible to find good-quality fish and shellfish at the world level and transport them to a pond in a safe manner and manage and farm them as livestock,

Then, the holding basket 22 together with the holding basket 22 is transported again to the second washing tank 5 and is washed for 5 seconds. Next, the fry together with the holding cage 22 is transported to the hibernation induction tank 10 where it is immersed for 2 minutes, and from the activated gills or side lines of the fry, the hibernation inducer (in this example, 10 μ / g DAD
LE) is taken into the fry body.

Thereafter, the fry into which the hibernation-inducing substance has been taken into the body is held in the hibernation-introduction reserve tank 13 until a complete pseudo-hibernation state is established. That is, after carrying out the holding basket 22 from the hibernation induction tank 10, the transport device 20 is rotated to transfer the holding basket 22 to the adjacent hibernation introduction preliminary tank 13.

In this test, the fry is immersed in the hibernation introduction preliminary tank 13 for about 30 minutes. Thereafter, the fry is transferred to the adjacent low-temperature tank 15 by rotating the hibernation holding basket 23 about one upper side of the hibernation holding basket 23 as a pivot. The fry transferred in the low-temperature bath 15 is stored for a required time.

In the present test, the processing time from the collection of the fry to the transport to the hibernation introduction preliminary tank 13 is 5 minutes and 30 seconds.
The processing capacity of the hibernation induction device 1 at one time depends on the density of the fry in the breeding tub, but when the larvae are bred at a density of 10% in the breeding tub 2, about 23 kg of the fry is processed by one processing. Can induce hibernation. The time required for the fry to be completely hibernated is 27 minutes and 30 seconds,
Since the apparatus of this example is capable of performing processing five times in a row, about 30
It is possible to induce about 115 kg of fry into hibernation in about a minute.
